5 | This is a high-level summary of the most important changes. | |
6 | For a full list of changes, see the git commit log; for example, | |
7 | https://github.com/openssl/openssl/commits/ and pick the appropriate | |
8 | release branch. | |
9 | ||
10 | Changes between 1.1.0f and 1.1.1 [xx XXX xxxx] | |
11 | ||
12 | *) Add multi-prime RSA (RFC 8017) support. | |
13 | [Paul Yang] | |
14 | ||
15 | *) Add SM3 implemented according to GB/T 32905-2016 | |
16 | [ Jack Lloyd <jack.lloyd@ribose.com>, | |
17 | Ronald Tse <ronald.tse@ribose.com>, | |
18 | Erick Borsboom <erick.borsboom@ribose.com> ] | |
19 | ||
20 | *) Add 'Maximum Fragment Length' TLS extension negotiation and support | |
21 | as documented in RFC6066. | |
22 | Based on a patch from Tomasz Moń | |
23 | [Filipe Raimundo da Silva] | |
24 | ||
25 | *) Add SM4 implemented according to GB/T 32907-2016. | |
26 | [ Jack Lloyd <jack.lloyd@ribose.com>, | |
27 | Ronald Tse <ronald.tse@ribose.com>, | |
28 | Erick Borsboom <erick.borsboom@ribose.com> ] | |
29 | ||
30 | *) Reimplement -newreq-nodes and ERR_error_string_n; the | |
31 | original author does not agree with the license change. | |
32 | [Rich Salz] | |
33 | ||
34 | *) Add ARIA AEAD TLS support. | |
35 | [Jon Spillett] | |
36 | ||
37 | *) Some macro definitions to support VS6 have been removed. Visual | |
38 | Studio 6 has not worked since 1.1.0 | |
39 | [Rich Salz] | |
40 | ||
41 | *) Add ERR_clear_last_mark(), to allow callers to clear the last mark | |
42 | without clearing the errors. | |
43 | [Richard Levitte] | |
44 | ||
45 | *) Add "atfork" functions. If building on a system that without | |
46 | pthreads, see doc/man3/OPENSSL_fork_prepare.pod for application | |
47 | requirements. The RAND facility now uses/requires this. | |
48 | [Rich Salz] | |
49 | ||
50 | *) Add SHA3. | |
51 | [Andy Polyakov] | |
52 | ||
53 | *) The UI API becomes a permanent and integral part of libcrypto, i.e. | |
54 | not possible to disable entirely. However, it's still possible to | |
55 | disable the console reading UI method, UI_OpenSSL() (use UI_null() | |
56 | as a fallback). | |
57 | ||
58 | To disable, configure with 'no-ui-console'. 'no-ui' is still | |
59 | possible to use as an alias. Check at compile time with the | |
60 | macro OPENSSL_NO_UI_CONSOLE. The macro OPENSSL_NO_UI is still | |
61 | possible to check and is an alias for OPENSSL_NO_UI_CONSOLE. | |
62 | [Richard Levitte] | |
63 | ||
64 | *) Add a STORE module, which implements a uniform and URI based reader of | |
65 | stores that can contain keys, certificates, CRLs and numerous other | |
66 | objects. The main API is loosely based on a few stdio functions, | |
67 | and includes OSSL_STORE_open, OSSL_STORE_load, OSSL_STORE_eof, | |
68 | OSSL_STORE_error and OSSL_STORE_close. | |
69 | The implementation uses backends called "loaders" to implement arbitrary | |
70 | URI schemes. There is one built in "loader" for the 'file' scheme. | |
71 | [Richard Levitte] | |
72 | ||
73 | *) Add devcrypto engine. This has been implemented against cryptodev-linux, | |
74 | then adjusted to work on FreeBSD 8.4 as well. | |
75 | Enable by configuring with 'enable-devcryptoeng'. This is done by default | |
76 | on BSD implementations, as cryptodev.h is assumed to exist on all of them. | |
77 | [Richard Levitte] | |
78 | ||
79 | *) Module names can prefixed with OSSL_ or OPENSSL_. This affects | |
80 | util/mkerr.pl, which is adapted to allow those prefixes, leading to | |
81 | error code calls like this: | |
82 | ||
83 | OSSL_FOOerr(OSSL_FOO_F_SOMETHING, OSSL_FOO_R_WHATEVER); | |
84 | ||
85 | With this change, we claim the namespaces OSSL and OPENSSL in a manner | |
86 | that can be encoded in C. For the foreseeable future, this will only | |
87 | affect new modules. | |
88 | [Richard Levitte and Tim Hudson] | |
89 | ||
90 | *) Removed BSD cryptodev engine. | |
91 | [Rich Salz] | |
92 | ||
93 | *) Add a build target 'build_all_generated', to build all generated files | |
94 | and only that. This can be used to prepare everything that requires | |
95 | things like perl for a system that lacks perl and then move everything | |
96 | to that system and do the rest of the build there. | |
97 | [Richard Levitte] | |
98 | ||
99 | *) In the UI interface, make it possible to duplicate the user data. This | |
100 | can be used by engines that need to retain the data for a longer time | |
101 | than just the call where this user data is passed. | |
102 | [Richard Levitte] | |
103 | ||
104 | *) Ignore the '-named_curve auto' value for compatibility of applications | |
105 | with OpenSSL 1.0.2. | |
106 | [Tomas Mraz <tmraz@fedoraproject.org>] | |
107 | ||
108 | *) Fragmented SSL/TLS alerts are no longer accepted. An alert message is 2 | |
109 | bytes long. In theory it is permissible in SSLv3 - TLSv1.2 to fragment such | |
110 | alerts across multiple records (some of which could be empty). In practice | |
111 | it make no sense to send an empty alert record, or to fragment one. TLSv1.3 | |
112 | prohibts this altogether and other libraries (BoringSSL, NSS) do not | |
113 | support this at all. Supporting it adds significant complexity to the | |
114 | record layer, and its removal is unlikely to cause inter-operability | |
115 | issues. | |
116 | [Matt Caswell] | |
117 | ||
118 | *) Add the ASN.1 types INT32, UINT32, INT64, UINT64 and variants prefixed | |
119 | with Z. These are meant to replace LONG and ZLONG and to be size safe. | |
120 | The use of LONG and ZLONG is discouraged and scheduled for deprecation | |
121 | in OpenSSL 1.2.0. | |
122 | [Richard Levitte] | |
123 | ||
124 | *) Add the 'z' and 'j' modifiers to BIO_printf() et al formatting string, | |
125 | 'z' is to be used for [s]size_t, and 'j' - with [u]int64_t. | |
126 | [Richard Levitte, Andy Polyakov] | |
127 | ||
128 | *) Add EC_KEY_get0_engine(), which does for EC_KEY what RSA_get0_engine() | |
129 | does for RSA, etc. | |
130 | [Richard Levitte] | |
131 | ||
132 | *) Have 'config' recognise 64-bit mingw and choose 'mingw64' as the target | |
133 | platform rather than 'mingw'. | |
134 | [Richard Levitte] | |
135 | ||
136 | *) The functions X509_STORE_add_cert and X509_STORE_add_crl return | |
137 | success if they are asked to add an object which already exists | |
138 | in the store. This change cascades to other functions which load | |
139 | certificates and CRLs. | |
140 | [Paul Dale] | |
141 | ||
142 | *) x86_64 assembly pack: annotate code with DWARF CFI directives to | |
143 | facilitate stack unwinding even from assembly subroutines. | |
144 | [Andy Polyakov] | |
145 | ||
146 | *) Remove VAX C specific definitions of OPENSSL_EXPORT, OPENSSL_EXTERN. | |
147 | Also remove OPENSSL_GLOBAL entirely, as it became a no-op. | |
148 | [Richard Levitte] | |
149 | ||
150 | *) Remove the VMS-specific reimplementation of gmtime from crypto/o_times.c. | |
151 | VMS C's RTL has a fully up to date gmtime() and gmtime_r() since V7.1, | |
152 | which is the minimum version we support. | |
153 | [Richard Levitte] | |
154 | ||
155 | *) Certificate time validation (X509_cmp_time) enforces stricter | |
156 | compliance with RFC 5280. Fractional seconds and timezone offsets | |
157 | are no longer allowed. | |
158 | [Emilia Käsper] | |
159 | ||
160 | *) Add support for ARIA | |
161 | [Paul Dale] | |
162 | ||
163 | *) s_client will now send the Server Name Indication (SNI) extension by | |
164 | default unless the new "-noservername" option is used. The server name is | |
165 | based on the host provided to the "-connect" option unless overridden by | |
166 | using "-servername". | |
167 | [Matt Caswell] | |
168 | ||
169 | *) Add support for SipHash | |
170 | [Todd Short] | |
171 | ||
172 | *) OpenSSL now fails if it receives an unrecognised record type in TLS1.0 | |
173 | or TLS1.1. Previously this only happened in SSLv3 and TLS1.2. This is to | |
174 | prevent issues where no progress is being made and the peer continually | |
175 | sends unrecognised record types, using up resources processing them. | |
176 | [Matt Caswell] | |
177 | ||
178 | *) 'openssl passwd' can now produce SHA256 and SHA512 based output, | |
179 | using the algorithm defined in | |
180 | https://www.akkadia.org/drepper/SHA-crypt.txt | |
181 | [Richard Levitte] | |
182 | ||
183 | *) Heartbeat support has been removed; the ABI is changed for now. | |
184 | [Richard Levitte, Rich Salz] | |
185 | ||
186 | *) Support for SSL_OP_NO_ENCRYPT_THEN_MAC in SSL_CONF_cmd. | |
187 | [Emilia Käsper] | |
188 | ||
189 | *) The RSA "null" method, which was partially supported to avoid patent | |
190 | issues, has been replaced to always returns NULL. | |
191 | [Rich Salz] | |
192 | ||
193 | ||
194 | Changes between 1.1.0f and 1.1.0g [2 Nov 2017] | |
195 | ||
196 | *) bn_sqrx8x_internal carry bug on x86_64 | |
197 | ||
198 | There is a carry propagating bug in the x86_64 Montgomery squaring | |
199 | procedure. No EC algorithms are affected. Analysis suggests that attacks | |
200 | against RSA and DSA as a result of this defect would be very difficult to | |
201 | perform and are not believed likely. Attacks against DH are considered just | |
202 | feasible (although very difficult) because most of the work necessary to | |
203 | deduce information about a private key may be performed offline. The amount | |
204 | of resources required for such an attack would be very significant and | |
205 | likely only accessible to a limited number of attackers. An attacker would | |
206 | additionally need online access to an unpatched system using the target | |
207 | private key in a scenario with persistent DH parameters and a private | |
208 | key that is shared between multiple clients. | |
209 | ||
210 | This only affects processors that support the BMI1, BMI2 and ADX extensions | |
211 | like Intel Broadwell (5th generation) and later or AMD Ryzen. | |
212 | ||
213 | This issue was reported to OpenSSL by the OSS-Fuzz project. | |
214 | (CVE-2017-3736) | |
215 | [Andy Polyakov] | |
216 | ||
217 | *) Malformed X.509 IPAddressFamily could cause OOB read | |
218 | ||
219 | If an X.509 certificate has a malformed IPAddressFamily extension, | |
220 | OpenSSL could do a one-byte buffer overread. The most likely result | |
221 | would be an erroneous display of the certificate in text format. | |
222 | ||
223 | This issue was reported to OpenSSL by the OSS-Fuzz project. | |
224 | (CVE-2017-3735) | |
225 | [Rich Salz] | |
226 | ||
227 | Changes between 1.1.0e and 1.1.0f [25 May 2017] | |
228 | ||
229 | *) Have 'config' recognise 64-bit mingw and choose 'mingw64' as the target | |
230 | platform rather than 'mingw'. | |
231 | [Richard Levitte] | |
232 | ||
233 | *) Remove the VMS-specific reimplementation of gmtime from crypto/o_times.c. | |
234 | VMS C's RTL has a fully up to date gmtime() and gmtime_r() since V7.1, | |
235 | which is the minimum version we support. | |
236 | [Richard Levitte] | |
237 | ||
238 | Changes between 1.1.0d and 1.1.0e [16 Feb 2017] | |
239 | ||
240 | *) Encrypt-Then-Mac renegotiation crash | |
241 | ||
242 | During a renegotiation handshake if the Encrypt-Then-Mac extension is | |
243 | negotiated where it was not in the original handshake (or vice-versa) then | |
244 | this can cause OpenSSL to crash (dependant on ciphersuite). Both clients | |
245 | and servers are affected. | |
246 | ||
247 | This issue was reported to OpenSSL by Joe Orton (Red Hat). | |
248 | (CVE-2017-3733) | |
249 | [Matt Caswell] | |
250 | ||
251 | Changes between 1.1.0c and 1.1.0d [26 Jan 2017] | |
252 | ||
253 | *) Truncated packet could crash via OOB read | |
254 | ||
255 | If one side of an SSL/TLS path is running on a 32-bit host and a specific | |
256 | cipher is being used, then a truncated packet can cause that host to | |
257 | perform an out-of-bounds read, usually resulting in a crash. | |
258 | ||
259 | This issue was reported to OpenSSL by Robert Święcki of Google. | |
260 | (CVE-2017-3731) | |
261 | [Andy Polyakov] | |
262 | ||
263 | *) Bad (EC)DHE parameters cause a client crash | |
264 | ||
265 | If a malicious server supplies bad parameters for a DHE or ECDHE key | |
266 | exchange then this can result in the client attempting to dereference a | |
267 | NULL pointer leading to a client crash. This could be exploited in a Denial | |
268 | of Service attack. | |
269 | ||
270 | This issue was reported to OpenSSL by Guido Vranken. | |
271 | (CVE-2017-3730) | |
272 | [Matt Caswell] | |
273 | ||
274 | *) BN_mod_exp may produce incorrect results on x86_64 | |
275 | ||
276 | There is a carry propagating bug in the x86_64 Montgomery squaring | |
277 | procedure. No EC algorithms are affected. Analysis suggests that attacks | |
278 | against RSA and DSA as a result of this defect would be very difficult to | |
279 | perform and are not believed likely. Attacks against DH are considered just | |
280 | feasible (although very difficult) because most of the work necessary to | |
281 | deduce information about a private key may be performed offline. The amount | |
282 | of resources required for such an attack would be very significant and | |
283 | likely only accessible to a limited number of attackers. An attacker would | |
284 | additionally need online access to an unpatched system using the target | |
285 | private key in a scenario with persistent DH parameters and a private | |
286 | key that is shared between multiple clients. For example this can occur by | |
287 | default in OpenSSL DHE based SSL/TLS ciphersuites. Note: This issue is very | |
288 | similar to CVE-2015-3193 but must be treated as a separate problem. | |
289 | ||
290 | This issue was reported to OpenSSL by the OSS-Fuzz project. | |
291 | (CVE-2017-3732) | |
292 | [Andy Polyakov] | |
293 | ||
294 | Changes between 1.1.0b and 1.1.0c [10 Nov 2016] | |
295 | ||
296 | *) ChaCha20/Poly1305 heap-buffer-overflow | |
297 | ||
298 | TLS connections using *-CHACHA20-POLY1305 ciphersuites are susceptible to | |
299 | a DoS attack by corrupting larger payloads. This can result in an OpenSSL | |
300 | crash. This issue is not considered to be exploitable beyond a DoS. | |
301 | ||
302 | This issue was reported to OpenSSL by Robert Święcki (Google Security Team) | |
303 | (CVE-2016-7054) | |
304 | [Richard Levitte] | |
305 | ||
306 | *) CMS Null dereference | |
307 | ||
308 | Applications parsing invalid CMS structures can crash with a NULL pointer | |
309 | dereference. This is caused by a bug in the handling of the ASN.1 CHOICE | |
310 | type in OpenSSL 1.1.0 which can result in a NULL value being passed to the | |
311 | structure callback if an attempt is made to free certain invalid encodings. | |
312 | Only CHOICE structures using a callback which do not handle NULL value are | |
313 | affected. | |
314 | ||
315 | This issue was reported to OpenSSL by Tyler Nighswander of ForAllSecure. | |
316 | (CVE-2016-7053) | |
317 | [Stephen Henson] | |
318 | ||
319 | *) Montgomery multiplication may produce incorrect results | |
320 | ||
321 | There is a carry propagating bug in the Broadwell-specific Montgomery | |
322 | multiplication procedure that handles input lengths divisible by, but | |
323 | longer than 256 bits. Analysis suggests that attacks against RSA, DSA | |
324 | and DH private keys are impossible. This is because the subroutine in | |
325 | question is not used in operations with the private key itself and an input | |
326 | of the attacker's direct choice. Otherwise the bug can manifest itself as | |
327 | transient authentication and key negotiation failures or reproducible | |
328 | erroneous outcome of public-key operations with specially crafted input. | |
329 | Among EC algorithms only Brainpool P-512 curves are affected and one | |
330 | presumably can attack ECDH key negotiation. Impact was not analyzed in | |
331 | detail, because pre-requisites for attack are considered unlikely. Namely | |
332 | multiple clients have to choose the curve in question and the server has to | |
333 | share the private key among them, neither of which is default behaviour. | |
334 | Even then only clients that chose the curve will be affected. | |
335 | ||
336 | This issue was publicly reported as transient failures and was not | |
337 | initially recognized as a security issue. Thanks to Richard Morgan for | |
338 | providing reproducible case. | |
339 | (CVE-2016-7055) | |
340 | [Andy Polyakov] | |
341 | ||
342 | *) Removed automatic addition of RPATH in shared libraries and executables, | |
343 | as this was a remainder from OpenSSL 1.0.x and isn't needed any more. | |
344 | [Richard Levitte] | |
345 | ||
346 | Changes between 1.1.0a and 1.1.0b [26 Sep 2016] | |
347 | ||
348 | *) Fix Use After Free for large message sizes | |
349 | ||
350 | The patch applied to address CVE-2016-6307 resulted in an issue where if a | |
351 | message larger than approx 16k is received then the underlying buffer to | |
352 | store the incoming message is reallocated and moved. Unfortunately a | |
353 | dangling pointer to the old location is left which results in an attempt to | |
354 | write to the previously freed location. This is likely to result in a | |
355 | crash, however it could potentially lead to execution of arbitrary code. | |
356 | ||
357 | This issue only affects OpenSSL 1.1.0a. | |
358 | ||
359 | This issue was reported to OpenSSL by Robert Święcki. | |
360 | (CVE-2016-6309) | |
361 | [Matt Caswell] | |
362 | ||
363 | Changes between 1.1.0 and 1.1.0a [22 Sep 2016] | |
364 | ||
365 | *) OCSP Status Request extension unbounded memory growth | |
366 | ||
367 | A malicious client can send an excessively large OCSP Status Request | |
368 | extension. If that client continually requests renegotiation, sending a | |
369 | large OCSP Status Request extension each time, then there will be unbounded | |
370 | memory growth on the server. This will eventually lead to a Denial Of | |
371 | Service attack through memory exhaustion. Servers with a default | |
372 | configuration are vulnerable even if they do not support OCSP. Builds using | |
373 | the "no-ocsp" build time option are not affected. | |
374 | ||
375 | This issue was reported to OpenSSL by Shi Lei (Gear Team, Qihoo 360 Inc.) | |
376 | (CVE-2016-6304) | |
377 | [Matt Caswell] | |
378 | ||
379 | *) SSL_peek() hang on empty record | |
380 | ||
381 | OpenSSL 1.1.0 SSL/TLS will hang during a call to SSL_peek() if the peer | |
382 | sends an empty record. This could be exploited by a malicious peer in a | |
383 | Denial Of Service attack. | |
384 | ||
385 | This issue was reported to OpenSSL by Alex Gaynor. | |
386 | (CVE-2016-6305) | |
387 | [Matt Caswell] | |
388 | ||
389 | *) Excessive allocation of memory in tls_get_message_header() and | |
390 | dtls1_preprocess_fragment() | |
391 | ||
392 | A (D)TLS message includes 3 bytes for its length in the header for the | |
393 | message. This would allow for messages up to 16Mb in length. Messages of | |
394 | this length are excessive and OpenSSL includes a check to ensure that a | |
395 | peer is sending reasonably sized messages in order to avoid too much memory | |
396 | being consumed to service a connection. A flaw in the logic of version | |
397 | 1.1.0 means that memory for the message is allocated too early, prior to | |
398 | the excessive message length check. Due to way memory is allocated in | |
399 | OpenSSL this could mean an attacker could force up to 21Mb to be allocated | |
400 | to service a connection. This could lead to a Denial of Service through | |
401 | memory exhaustion. However, the excessive message length check still takes | |
402 | place, and this would cause the connection to immediately fail. Assuming | |
403 | that the application calls SSL_free() on the failed connection in a timely | |
404 | manner then the 21Mb of allocated memory will then be immediately freed | |
405 | again. Therefore the excessive memory allocation will be transitory in | |
406 | nature. This then means that there is only a security impact if: | |
407 | ||
408 | 1) The application does not call SSL_free() in a timely manner in the event | |
409 | that the connection fails | |
410 | or | |
411 | 2) The application is working in a constrained environment where there is | |
412 | very little free memory | |
413 | or | |
414 | 3) The attacker initiates multiple connection attempts such that there are | |
415 | multiple connections in a state where memory has been allocated for the | |
416 | connection; SSL_free() has not yet been called; and there is insufficient | |
417 | memory to service the multiple requests. | |
418 | ||
419 | Except in the instance of (1) above any Denial Of Service is likely to be | |
420 | transitory because as soon as the connection fails the memory is | |
421 | subsequently freed again in the SSL_free() call. However there is an | |
422 | increased risk during this period of application crashes due to the lack of | |
423 | memory - which would then mean a more serious Denial of Service. | |
424 | ||
425 | This issue was reported to OpenSSL by Shi Lei (Gear Team, Qihoo 360 Inc.) | |
426 | (CVE-2016-6307 and CVE-2016-6308) | |
427 | [Matt Caswell] | |
428 | ||
429 | *) solaris-x86-cc, i.e. 32-bit configuration with vendor compiler, | |
430 | had to be removed. Primary reason is that vendor assembler can't | |
431 | assemble our modules with -KPIC flag. As result it, assembly | |
432 | support, was not even available as option. But its lack means | |
433 | lack of side-channel resistant code, which is incompatible with | |
434 | security by todays standards. Fortunately gcc is readily available | |
435 | prepackaged option, which we firmly point at... | |
436 | [Andy Polyakov] | |
437 | ||
438 | Changes between 1.0.2h and 1.1.0 [25 Aug 2016] | |
439 | ||
440 | *) Windows command-line tool supports UTF-8 opt-in option for arguments | |
441 | and console input. Setting OPENSSL_WIN32_UTF8 environment variable | |
442 | (to any value) allows Windows user to access PKCS#12 file generated | |
443 | with Windows CryptoAPI and protected with non-ASCII password, as well | |
444 | as files generated under UTF-8 locale on Linux also protected with | |
445 | non-ASCII password. | |
446 | [Andy Polyakov] | |
447 | ||
448 | *) To mitigate the SWEET32 attack (CVE-2016-2183), 3DES cipher suites | |
449 | have been disabled by default and removed from DEFAULT, just like RC4. | |
450 | See the RC4 item below to re-enable both. | |
451 | [Rich Salz] | |
452 | ||
453 | *) The method for finding the storage location for the Windows RAND seed file | |
454 | has changed. First we check %RANDFILE%. If that is not set then we check | |
455 | the directories %HOME%, %USERPROFILE% and %SYSTEMROOT% in that order. If | |
456 | all else fails we fall back to C:\. | |
457 | [Matt Caswell] | |
458 | ||
459 | *) The EVP_EncryptUpdate() function has had its return type changed from void | |
460 | to int. A return of 0 indicates and error while a return of 1 indicates | |
461 | success. | |
462 | [Matt Caswell] | |
463 | ||
464 | *) The flags RSA_FLAG_NO_CONSTTIME, DSA_FLAG_NO_EXP_CONSTTIME and | |
465 | DH_FLAG_NO_EXP_CONSTTIME which previously provided the ability to switch | |
466 | off the constant time implementation for RSA, DSA and DH have been made | |
467 | no-ops and deprecated. | |
468 | [Matt Caswell] | |
469 | ||
470 | *) Windows RAND implementation was simplified to only get entropy by | |
471 | calling CryptGenRandom(). Various other RAND-related tickets | |
472 | were also closed. | |
473 | [Joseph Wylie Yandle, Rich Salz] | |
474 | ||
475 | *) The stack and lhash API's were renamed to start with OPENSSL_SK_ | |
476 | and OPENSSL_LH_, respectively. The old names are available | |
477 | with API compatibility. They new names are now completely documented. | |
478 | [Rich Salz] | |
479 | ||
480 | *) Unify TYPE_up_ref(obj) methods signature. | |
481 | SSL_CTX_up_ref(), SSL_up_ref(), X509_up_ref(), EVP_PKEY_up_ref(), | |
482 | X509_CRL_up_ref(), X509_OBJECT_up_ref_count() methods are now returning an | |
483 | int (instead of void) like all others TYPE_up_ref() methods. | |
484 | So now these methods also check the return value of CRYPTO_atomic_add(), | |
485 | and the validity of object reference counter. | |
486 | [fdasilvayy@gmail.com] | |
487 | ||
488 | *) With Windows Visual Studio builds, the .pdb files are installed | |
489 | alongside the installed libraries and executables. For a static | |
490 | library installation, ossl_static.pdb is the associate compiler | |
491 | generated .pdb file to be used when linking programs. | |
492 | [Richard Levitte] | |
493 | ||
494 | *) Remove openssl.spec. Packaging files belong with the packagers. | |
495 | [Richard Levitte] | |
496 | ||
497 | *) Automatic Darwin/OSX configuration has had a refresh, it will now | |
498 | recognise x86_64 architectures automatically. You can still decide | |
499 | to build for a different bitness with the environment variable | |
500 | KERNEL_BITS (can be 32 or 64), for example: | |
501 | ||
502 | KERNEL_BITS=32 ./config | |
503 | ||
504 | [Richard Levitte] | |
505 | ||
506 | *) Change default algorithms in pkcs8 utility to use PKCS#5 v2.0, | |
507 | 256 bit AES and HMAC with SHA256. | |
508 | [Steve Henson] | |
509 | ||
510 | *) Remove support for MIPS o32 ABI on IRIX (and IRIX only). | |
511 | [Andy Polyakov] | |
512 | ||
513 | *) Triple-DES ciphers have been moved from HIGH to MEDIUM. | |
514 | [Rich Salz] | |
515 | ||
516 | *) To enable users to have their own config files and build file templates, | |
517 | Configure looks in the directory indicated by the environment variable | |
518 | OPENSSL_LOCAL_CONFIG_DIR as well as the in-source Configurations/ | |
519 | directory. On VMS, OPENSSL_LOCAL_CONFIG_DIR is expected to be a logical | |
520 | name and is used as is. | |
521 | [Richard Levitte] | |
522 | ||
523 | *) The following datatypes were made opaque: X509_OBJECT, X509_STORE_CTX, | |
524 | X509_STORE, X509_LOOKUP, and X509_LOOKUP_METHOD. The unused type | |
525 | X509_CERT_FILE_CTX was removed. | |
526 | [Rich Salz] | |
527 | ||
528 | *) "shared" builds are now the default. To create only static libraries use | |
529 | the "no-shared" Configure option. | |
530 | [Matt Caswell] | |
531 | ||
532 | *) Remove the no-aes, no-hmac, no-rsa, no-sha and no-md5 Configure options. | |
533 | All of these option have not worked for some while and are fundamental | |
534 | algorithms. | |
535 | [Matt Caswell] | |
536 | ||
537 | *) Make various cleanup routines no-ops and mark them as deprecated. Most | |
538 | global cleanup functions are no longer required because they are handled | |
539 | via auto-deinit (see OPENSSL_init_crypto and OPENSSL_init_ssl man pages). | |
540 | Explicitly de-initing can cause problems (e.g. where a library that uses | |
541 | OpenSSL de-inits, but an application is still using it). The affected | |
542 | functions are CONF_modules_free(), ENGINE_cleanup(), OBJ_cleanup(), | |
543 | EVP_cleanup(), BIO_sock_cleanup(), CRYPTO_cleanup_all_ex_data(), | |
544 | RAND_cleanup(), SSL_COMP_free_compression_methods(), ERR_free_strings() and | |
545 | COMP_zlib_cleanup(). | |
546 | [Matt Caswell] | |
547 | ||
548 | *) --strict-warnings no longer enables runtime debugging options | |
549 | such as REF_DEBUG. Instead, debug options are automatically | |
550 | enabled with '--debug' builds. | |
551 | [Andy Polyakov, Emilia Käsper] | |
552 | ||
553 | *) Made DH and DH_METHOD opaque. The structures for managing DH objects | |
554 | have been moved out of the public header files. New functions for managing | |
555 | these have been added. | |
556 | [Matt Caswell] | |
557 | ||
558 | *) Made RSA and RSA_METHOD opaque. The structures for managing RSA | |
559 | objects have been moved out of the public header files. New | |
560 | functions for managing these have been added. | |
561 | [Richard Levitte] | |
562 | ||
563 | *) Made DSA and DSA_METHOD opaque. The structures for managing DSA objects | |
564 | have been moved out of the public header files. New functions for managing | |
565 | these have been added. | |
566 | [Matt Caswell] | |
567 | ||
568 | *) Made BIO and BIO_METHOD opaque. The structures for managing BIOs have been | |
569 | moved out of the public header files. New functions for managing these | |
570 | have been added. | |
571 | [Matt Caswell] | |
572 | ||
573 | *) Removed no-rijndael as a config option. Rijndael is an old name for AES. | |
574 | [Matt Caswell] | |
575 | ||
576 | *) Removed the mk1mf build scripts. | |
577 | [Richard Levitte] | |
578 | ||
579 | *) Headers are now wrapped, if necessary, with OPENSSL_NO_xxx, so | |
580 | it is always safe to #include a header now. | |
581 | [Rich Salz] | |
582 | ||
583 | *) Removed the aged BC-32 config and all its supporting scripts | |
584 | [Richard Levitte] | |
585 | ||
586 | *) Removed support for Ultrix, Netware, and OS/2. | |
587 | [Rich Salz] | |
588 | ||
589 | *) Add support for HKDF. | |
590 | [Alessandro Ghedini] | |
591 | ||
592 | *) Add support for blake2b and blake2s | |
593 | [Bill Cox] | |
594 | ||
595 | *) Added support for "pipelining". Ciphers that have the | |
596 | EVP_CIPH_FLAG_PIPELINE flag set have a capability to process multiple | |
597 | encryptions/decryptions simultaneously. There are currently no built-in | |
598 | ciphers with this property but the expectation is that engines will be able | |
599 | to offer it to significantly improve throughput. Support has been extended | |
600 | into libssl so that multiple records for a single connection can be | |
601 | processed in one go (for >=TLS 1.1). | |
602 | [Matt Caswell] | |
603 | ||
604 | *) Added the AFALG engine. This is an async capable engine which is able to | |
605 | offload work to the Linux kernel. In this initial version it only supports | |
606 | AES128-CBC. The kernel must be version 4.1.0 or greater. | |
607 | [Catriona Lucey] | |
608 | ||
609 | *) OpenSSL now uses a new threading API. It is no longer necessary to | |
610 | set locking callbacks to use OpenSSL in a multi-threaded environment. There | |
611 | are two supported threading models: pthreads and windows threads. It is | |
612 | also possible to configure OpenSSL at compile time for "no-threads". The | |
613 | old threading API should no longer be used. The functions have been | |
614 | replaced with "no-op" compatibility macros. | |
615 | [Alessandro Ghedini, Matt Caswell] | |
616 | ||
617 | *) Modify behavior of ALPN to invoke callback after SNI/servername | |
618 | callback, such that updates to the SSL_CTX affect ALPN. | |
619 | [Todd Short] | |
620 | ||
621 | *) Add SSL_CIPHER queries for authentication and key-exchange. | |
622 | [Todd Short] | |
623 | ||
624 | *) Changes to the DEFAULT cipherlist: | |
625 | - Prefer (EC)DHE handshakes over plain RSA. | |
626 | - Prefer AEAD ciphers over legacy ciphers. | |
627 | - Prefer ECDSA over RSA when both certificates are available. | |
628 | - Prefer TLSv1.2 ciphers/PRF. | |
629 | - Remove DSS, SEED, IDEA, CAMELLIA, and AES-CCM from the | |
630 | default cipherlist. | |
631 | [Emilia Käsper] | |
632 | ||
633 | *) Change the ECC default curve list to be this, in order: x25519, | |
634 | secp256r1, secp521r1, secp384r1. | |
635 | [Rich Salz] | |
636 | ||
637 | *) RC4 based libssl ciphersuites are now classed as "weak" ciphers and are | |
638 | disabled by default. They can be re-enabled using the | |
639 | enable-weak-ssl-ciphers option to Configure. | |
640 | [Matt Caswell] | |
641 | ||
642 | *) If the server has ALPN configured, but supports no protocols that the | |
643 | client advertises, send a fatal "no_application_protocol" alert. | |
644 | This behaviour is SHALL in RFC 7301, though it isn't universally | |
645 | implemented by other servers. | |
646 | [Emilia Käsper] | |
647 | ||
648 | *) Add X25519 support. | |
649 | Add ASN.1 and EVP_PKEY methods for X25519. This includes support | |
650 | for public and private key encoding using the format documented in | |
651 | draft-ietf-curdle-pkix-02. The corresponding EVP_PKEY method supports | |
652 | key generation and key derivation. | |
653 | ||
654 | TLS support complies with draft-ietf-tls-rfc4492bis-08 and uses | |
655 | X25519(29). | |
656 | [Steve Henson] | |
657 | ||
658 | *) Deprecate SRP_VBASE_get_by_user. | |
659 | SRP_VBASE_get_by_user had inconsistent memory management behaviour. | |
660 | In order to fix an unavoidable memory leak (CVE-2016-0798), | |
661 | SRP_VBASE_get_by_user was changed to ignore the "fake user" SRP | |
662 | seed, even if the seed is configured. | |
663 | ||
664 | Users should use SRP_VBASE_get1_by_user instead. Note that in | |
665 | SRP_VBASE_get1_by_user, caller must free the returned value. Note | |
666 | also that even though configuring the SRP seed attempts to hide | |
667 | invalid usernames by continuing the handshake with fake | |
668 | credentials, this behaviour is not constant time and no strong | |
669 | guarantees are made that the handshake is indistinguishable from | |
670 | that of a valid user. | |
671 | [Emilia Käsper] | |
672 | ||
673 | *) Configuration change; it's now possible to build dynamic engines | |
674 | without having to build shared libraries and vice versa. This | |
675 | only applies to the engines in engines/, those in crypto/engine/ | |
676 | will always be built into libcrypto (i.e. "static"). | |
677 | ||
678 | Building dynamic engines is enabled by default; to disable, use | |
679 | the configuration option "disable-dynamic-engine". | |
680 | ||
681 | The only requirements for building dynamic engines are the | |
682 | presence of the DSO module and building with position independent | |
683 | code, so they will also automatically be disabled if configuring | |
684 | with "disable-dso" or "disable-pic". | |
685 | ||
686 | The macros OPENSSL_NO_STATIC_ENGINE and OPENSSL_NO_DYNAMIC_ENGINE | |
687 | are also taken away from openssl/opensslconf.h, as they are | |
688 | irrelevant. | |
689 | [Richard Levitte] | |
690 | ||
691 | *) Configuration change; if there is a known flag to compile | |
692 | position independent code, it will always be applied on the | |
693 | libcrypto and libssl object files, and never on the application | |
694 | object files. This means other libraries that use routines from | |
695 | libcrypto / libssl can be made into shared libraries regardless | |
696 | of how OpenSSL was configured. | |
697 | ||
698 | If this isn't desirable, the configuration options "disable-pic" | |
699 | or "no-pic" can be used to disable the use of PIC. This will | |
700 | also disable building shared libraries and dynamic engines. | |
701 | [Richard Levitte] | |
702 | ||
703 | *) Removed JPAKE code. It was experimental and has no wide use. | |
704 | [Rich Salz] | |
705 | ||
706 | *) The INSTALL_PREFIX Makefile variable has been renamed to | |
707 | DESTDIR. That makes for less confusion on what this variable | |
708 | is for. Also, the configuration option --install_prefix is | |
709 | removed. | |
710 | [Richard Levitte] | |
711 | ||
712 | *) Heartbeat for TLS has been removed and is disabled by default | |
713 | for DTLS; configure with enable-heartbeats. Code that uses the | |
714 | old #define's might need to be updated. | |
715 | [Emilia Käsper, Rich Salz] | |
716 | ||
717 | *) Rename REF_CHECK to REF_DEBUG. | |
718 | [Rich Salz] | |
719 | ||
720 | *) New "unified" build system | |
721 | ||
722 | The "unified" build system is aimed to be a common system for all | |
723 | platforms we support. With it comes new support for VMS. | |
724 | ||
725 | This system builds supports building in a different directory tree | |
726 | than the source tree. It produces one Makefile (for unix family | |
727 | or lookalikes), or one descrip.mms (for VMS). | |
728 | ||
729 | The source of information to make the Makefile / descrip.mms is | |
730 | small files called 'build.info', holding the necessary | |
731 | information for each directory with source to compile, and a | |
732 | template in Configurations, like unix-Makefile.tmpl or | |
733 | descrip.mms.tmpl. | |
734 | ||
735 | With this change, the library names were also renamed on Windows | |
736 | and on VMS. They now have names that are closer to the standard | |
737 | on Unix, and include the major version number, and in certain | |
738 | cases, the architecture they are built for. See "Notes on shared | |
739 | libraries" in INSTALL. | |
740 | ||
741 | We rely heavily on the perl module Text::Template. | |
742 | [Richard Levitte] | |
743 | ||
744 | *) Added support for auto-initialisation and de-initialisation of the library. | |
745 | OpenSSL no longer requires explicit init or deinit routines to be called, | |
746 | except in certain circumstances. See the OPENSSL_init_crypto() and | |
747 | OPENSSL_init_ssl() man pages for further information. | |
748 | [Matt Caswell] | |
749 | ||
750 | *) The arguments to the DTLSv1_listen function have changed. Specifically the | |
751 | "peer" argument is now expected to be a BIO_ADDR object. | |
752 | ||
753 | *) Rewrite of BIO networking library. The BIO library lacked consistent | |
754 | support of IPv6, and adding it required some more extensive | |
755 | modifications. This introduces the BIO_ADDR and BIO_ADDRINFO types, | |
756 | which hold all types of addresses and chains of address information. | |
757 | It also introduces a new API, with functions like BIO_socket, | |
758 | BIO_connect, BIO_listen, BIO_lookup and a rewrite of BIO_accept. | |
759 | The source/sink BIOs BIO_s_connect, BIO_s_accept and BIO_s_datagram | |
760 | have been adapted accordingly. | |
761 | [Richard Levitte] | |
762 | ||
763 | *) RSA_padding_check_PKCS1_type_1 now accepts inputs with and without | |
764 | the leading 0-byte. | |
765 | [Emilia Käsper] | |
766 | ||
767 | *) CRIME protection: disable compression by default, even if OpenSSL is | |
768 | compiled with zlib enabled. Applications can still enable compression | |
769 | by calling SSL_CTX_clear_options(ctx, SSL_OP_NO_COMPRESSION), or by | |
770 | using the SSL_CONF library to configure compression. | |
771 | [Emilia Käsper] | |
772 | ||
773 | *) The signature of the session callback configured with | |
774 | SSL_CTX_sess_set_get_cb was changed. The read-only input buffer | |
775 | was explicitly marked as 'const unsigned char*' instead of | |
776 | 'unsigned char*'. | |
777 | [Emilia Käsper] | |
778 | ||
779 | *) Always DPURIFY. Remove the use of uninitialized memory in the | |
780 | RNG, and other conditional uses of DPURIFY. This makes -DPURIFY a no-op. | |
781 | [Emilia Käsper] | |
782 | ||
783 | *) Removed many obsolete configuration items, including | |
784 | DES_PTR, DES_RISC1, DES_RISC2, DES_INT | |
785 | MD2_CHAR, MD2_INT, MD2_LONG | |
786 | BF_PTR, BF_PTR2 | |
787 | IDEA_SHORT, IDEA_LONG | |
788 | RC2_SHORT, RC2_LONG, RC4_LONG, RC4_CHUNK, RC4_INDEX | |
789 | [Rich Salz, with advice from Andy Polyakov] | |
790 | ||
791 | *) Many BN internals have been moved to an internal header file. | |
792 | [Rich Salz with help from Andy Polyakov] | |
793 | ||
794 | *) Configuration and writing out the results from it has changed. | |
795 | Files such as Makefile include/openssl/opensslconf.h and are now | |
796 | produced through general templates, such as Makefile.in and | |
797 | crypto/opensslconf.h.in and some help from the perl module | |
798 | Text::Template. | |
799 | ||
800 | Also, the center of configuration information is no longer | |
801 | Makefile. Instead, Configure produces a perl module in | |
802 | configdata.pm which holds most of the config data (in the hash | |
803 | table %config), the target data that comes from the target | |
804 | configuration in one of the Configurations/*.conf files (in | |
805 | %target). | |
806 | [Richard Levitte] | |
807 | ||
808 | *) To clarify their intended purposes, the Configure options | |
809 | --prefix and --openssldir change their semantics, and become more | |
810 | straightforward and less interdependent. | |
811 | ||
812 | --prefix shall be used exclusively to give the location INSTALLTOP | |
813 | where programs, scripts, libraries, include files and manuals are | |
814 | going to be installed. The default is now /usr/local. | |
815 | ||
816 | --openssldir shall be used exclusively to give the default | |
817 | location OPENSSLDIR where certificates, private keys, CRLs are | |
818 | managed. This is also where the default openssl.cnf gets | |
819 | installed. | |
820 | If the directory given with this option is a relative path, the | |
821 | values of both the --prefix value and the --openssldir value will | |
822 | be combined to become OPENSSLDIR. | |
823 | The default for --openssldir is INSTALLTOP/ssl. | |
824 | ||
825 | Anyone who uses --openssldir to specify where OpenSSL is to be | |
826 | installed MUST change to use --prefix instead. | |
827 | [Richard Levitte] | |
828 | ||
829 | *) The GOST engine was out of date and therefore it has been removed. An up | |
830 | to date GOST engine is now being maintained in an external repository. | |
831 | See: https://wiki.openssl.org/index.php/Binaries. Libssl still retains | |
832 | support for GOST ciphersuites (these are only activated if a GOST engine | |
833 | is present). | |
834 | [Matt Caswell] | |
835 | ||
836 | *) EGD is no longer supported by default; use enable-egd when | |
837 | configuring. | |
838 | [Ben Kaduk and Rich Salz] | |
839 | ||
840 | *) The distribution now has Makefile.in files, which are used to | |
841 | create Makefile's when Configure is run. *Configure must be run | |
842 | before trying to build now.* | |
843 | [Rich Salz] | |
844 | ||
845 | *) The return value for SSL_CIPHER_description() for error conditions | |
846 | has changed. | |
847 | [Rich Salz] | |
848 | ||
849 | *) Support for RFC6698/RFC7671 DANE TLSA peer authentication. | |
850 | ||
851 | Obtaining and performing DNSSEC validation of TLSA records is | |
852 | the application's responsibility. The application provides | |
853 | the TLSA records of its choice to OpenSSL, and these are then | |
854 | used to authenticate the peer. | |
855 | ||
856 | The TLSA records need not even come from DNS. They can, for | |
857 | example, be used to implement local end-entity certificate or | |
858 | trust-anchor "pinning", where the "pin" data takes the form | |
859 | of TLSA records, which can augment or replace verification | |
860 | based on the usual WebPKI public certification authorities. | |
861 | [Viktor Dukhovni] | |
862 | ||
863 | *) Revert default OPENSSL_NO_DEPRECATED setting. Instead OpenSSL | |
864 | continues to support deprecated interfaces in default builds. | |
865 | However, applications are strongly advised to compile their | |
866 | source files with -DOPENSSL_API_COMPAT=0x10100000L, which hides | |
867 | the declarations of all interfaces deprecated in 0.9.8, 1.0.0 | |
868 | or the 1.1.0 releases. | |
869 | ||
870 | In environments in which all applications have been ported to | |
871 | not use any deprecated interfaces OpenSSL's Configure script | |
872 | should be used with the --api=1.1.0 option to entirely remove | |
873 | support for the deprecated features from the library and | |
874 | unconditionally disable them in the installed headers. | |
875 | Essentially the same effect can be achieved with the "no-deprecated" | |
876 | argument to Configure, except that this will always restrict | |
877 | the build to just the latest API, rather than a fixed API | |
878 | version. | |
879 | ||
880 | As applications are ported to future revisions of the API, | |
881 | they should update their compile-time OPENSSL_API_COMPAT define | |
882 | accordingly, but in most cases should be able to continue to | |
883 | compile with later releases. | |
884 | ||
885 | The OPENSSL_API_COMPAT versions for 1.0.0, and 0.9.8 are | |
886 | 0x10000000L and 0x00908000L, respectively. However those | |
887 | versions did not support the OPENSSL_API_COMPAT feature, and | |
888 | so applications are not typically tested for explicit support | |
889 | of just the undeprecated features of either release. | |
890 | [Viktor Dukhovni] | |
891 | ||
892 | *) Add support for setting the minimum and maximum supported protocol. | |
893 | It can bet set via the SSL_set_min_proto_version() and | |
894 | SSL_set_max_proto_version(), or via the SSL_CONF's MinProtocol and | |
895 | MaxProtocol. It's recommended to use the new APIs to disable | |
896 | protocols instead of disabling individual protocols using | |
897 | SSL_set_options() or SSL_CONF's Protocol. This change also | |
898 | removes support for disabling TLS 1.2 in the OpenSSL TLS | |
899 | client at compile time by defining OPENSSL_NO_TLS1_2_CLIENT. | |
900 | [Kurt Roeckx] | |
901 | ||
902 | *) Support for ChaCha20 and Poly1305 added to libcrypto and libssl. | |
903 | [Andy Polyakov] | |
904 | ||
905 | *) New EC_KEY_METHOD, this replaces the older ECDSA_METHOD and ECDH_METHOD | |
906 | and integrates ECDSA and ECDH functionality into EC. Implementations can | |
907 | now redirect key generation and no longer need to convert to or from | |
908 | ECDSA_SIG format. | |
909 | ||
910 | Note: the ecdsa.h and ecdh.h headers are now no longer needed and just | |
911 | include the ec.h header file instead. | |
912 | [Steve Henson] | |
913 | ||
914 | *) Remove support for all 40 and 56 bit ciphers. This includes all the export | |
915 | ciphers who are no longer supported and drops support the ephemeral RSA key | |
916 | exchange. The LOW ciphers currently doesn't have any ciphers in it. | |
917 | [Kurt Roeckx] | |
918 | ||
919 | *) Made EVP_MD_CTX, EVP_MD, EVP_CIPHER_CTX, EVP_CIPHER and HMAC_CTX | |
920 | opaque. For HMAC_CTX, the following constructors and destructors | |
921 | were added: | |
922 | ||
923 | HMAC_CTX *HMAC_CTX_new(void); | |
924 | void HMAC_CTX_free(HMAC_CTX *ctx); | |
925 | ||
926 | For EVP_MD and EVP_CIPHER, complete APIs to create, fill and | |
927 | destroy such methods has been added. See EVP_MD_meth_new(3) and | |
928 | EVP_CIPHER_meth_new(3) for documentation. | |
929 | ||
930 | Additional changes: | |
931 | 1) EVP_MD_CTX_cleanup(), EVP_CIPHER_CTX_cleanup() and | |
932 | HMAC_CTX_cleanup() were removed. HMAC_CTX_reset() and | |
933 | EVP_MD_CTX_reset() should be called instead to reinitialise | |
934 | an already created structure. | |
935 | 2) For consistency with the majority of our object creators and | |
936 | destructors, EVP_MD_CTX_(create|destroy) were renamed to | |
937 | EVP_MD_CTX_(new|free). The old names are retained as macros | |
938 | for deprecated builds. | |
939 | [Richard Levitte] | |
940 | ||
941 | *) Added ASYNC support. Libcrypto now includes the async sub-library to enable | |
942 | cryptographic operations to be performed asynchronously as long as an | |
943 | asynchronous capable engine is used. See the ASYNC_start_job() man page for | |
944 | further details. Libssl has also had this capability integrated with the | |
945 | introduction of the new mode SSL_MODE_ASYNC and associated error | |
946 | SSL_ERROR_WANT_ASYNC. See the SSL_CTX_set_mode() and SSL_get_error() man | |
947 | pages. This work was developed in partnership with Intel Corp. | |
948 | [Matt Caswell] | |
949 | ||
950 | *) SSL_{CTX_}set_ecdh_auto() has been removed and ECDH is support is | |
951 | always enabled now. If you want to disable the support you should | |
952 | exclude it using the list of supported ciphers. This also means that the | |
953 | "-no_ecdhe" option has been removed from s_server. | |
954 | [Kurt Roeckx] | |
955 | ||
956 | *) SSL_{CTX}_set_tmp_ecdh() which can set 1 EC curve now internally calls | |
957 | SSL_{CTX_}set1_curves() which can set a list. | |
958 | [Kurt Roeckx] | |
959 | ||
960 | *) Remove support for SSL_{CTX_}set_tmp_ecdh_callback(). You should set the | |
961 | curve you want to support using SSL_{CTX_}set1_curves(). | |
962 | [Kurt Roeckx] | |
963 | ||
964 | *) State machine rewrite. The state machine code has been significantly | |
965 | refactored in order to remove much duplication of code and solve issues | |
966 | with the old code (see ssl/statem/README for further details). This change | |
967 | does have some associated API changes. Notably the SSL_state() function | |
968 | has been removed and replaced by SSL_get_state which now returns an | |
969 | "OSSL_HANDSHAKE_STATE" instead of an int. SSL_set_state() has been removed | |
970 | altogether. The previous handshake states defined in ssl.h and ssl3.h have | |
971 | also been removed. | |
972 | [Matt Caswell] | |
973 | ||
974 | *) All instances of the string "ssleay" in the public API were replaced | |
975 | with OpenSSL (case-matching; e.g., OPENSSL_VERSION for #define's) | |
976 | Some error codes related to internal RSA_eay API's were renamed. | |
977 | [Rich Salz] | |
978 | ||
979 | *) The demo files in crypto/threads were moved to demo/threads. | |
980 | [Rich Salz] | |
981 | ||
982 | *) Removed obsolete engines: 4758cca, aep, atalla, cswift, nuron, gmp, | |
983 | sureware and ubsec. | |
984 | [Matt Caswell, Rich Salz] | |
985 | ||
986 | *) New ASN.1 embed macro. | |
987 | ||
988 | New ASN.1 macro ASN1_EMBED. This is the same as ASN1_SIMPLE except the | |
989 | structure is not allocated: it is part of the parent. That is instead of | |
990 | ||
991 | FOO *x; | |
992 | ||
993 | it must be: | |
994 | ||
995 | FOO x; | |
996 | ||
997 | This reduces memory fragmentation and make it impossible to accidentally | |
998 | set a mandatory field to NULL. | |
999 | ||
1000 | This currently only works for some fields specifically a SEQUENCE, CHOICE, | |
1001 | or ASN1_STRING type which is part of a parent SEQUENCE. Since it is | |
1002 | equivalent to ASN1_SIMPLE it cannot be tagged, OPTIONAL, SET OF or | |
1003 | SEQUENCE OF. | |
1004 | [Steve Henson] | |
1005 | ||
1006 | *) Remove EVP_CHECK_DES_KEY, a compile-time option that never compiled. | |
1007 | [Emilia Käsper] | |
1008 | ||
1009 | *) Removed DES and RC4 ciphersuites from DEFAULT. Also removed RC2 although | |
1010 | in 1.0.2 EXPORT was already removed and the only RC2 ciphersuite is also | |
1011 | an EXPORT one. COMPLEMENTOFDEFAULT has been updated accordingly to add | |
1012 | DES and RC4 ciphersuites. | |
1013 | [Matt Caswell] | |
1014 | ||
1015 | *) Rewrite EVP_DecodeUpdate (base64 decoding) to fix several bugs. | |
1016 | This changes the decoding behaviour for some invalid messages, | |
1017 | though the change is mostly in the more lenient direction, and | |
1018 | legacy behaviour is preserved as much as possible. | |
1019 | [Emilia Käsper] | |
1020 | ||
1021 | *) Fix no-stdio build. | |
1022 | [ David Woodhouse <David.Woodhouse@intel.com> and also | |
1023 | Ivan Nestlerode <ivan.nestlerode@sonos.com> ] | |
1024 | ||
1025 | *) New testing framework | |
1026 | The testing framework has been largely rewritten and is now using | |
1027 | perl and the perl modules Test::Harness and an extended variant of | |
1028 | Test::More called OpenSSL::Test to do its work. All test scripts in | |
1029 | test/ have been rewritten into test recipes, and all direct calls to | |
1030 | executables in test/Makefile have become individual recipes using the | |
1031 | simplified testing OpenSSL::Test::Simple. | |
1032 | ||
1033 | For documentation on our testing modules, do: | |
1034 | ||
1035 | perldoc test/testlib/OpenSSL/Test/Simple.pm | |
1036 | perldoc test/testlib/OpenSSL/Test.pm | |
1037 | ||
1038 | [Richard Levitte] | |
1039 | ||
1040 | *) Revamped memory debug; only -DCRYPTO_MDEBUG and -DCRYPTO_MDEBUG_ABORT | |
1041 | are used; the latter aborts on memory leaks (usually checked on exit). | |
1042 | Some undocumented "set malloc, etc., hooks" functions were removed | |
1043 | and others were changed. All are now documented. | |
1044 | [Rich Salz] | |
1045 | ||
1046 | *) In DSA_generate_parameters_ex, if the provided seed is too short, | |
1047 | return an error | |
1048 | [Rich Salz and Ismo Puustinen <ismo.puustinen@intel.com>] | |
1049 | ||
1050 | *) Rewrite PSK to support ECDHE_PSK, DHE_PSK and RSA_PSK. Add ciphersuites | |
1051 | from RFC4279, RFC4785, RFC5487, RFC5489. | |
1052 | ||
1053 | Thanks to Christian J. Dietrich and Giuseppe D'Angelo for the | |
1054 | original RSA_PSK patch. | |
1055 | [Steve Henson] | |
1056 | ||
1057 | *) Dropped support for the SSL3_FLAGS_DELAY_CLIENT_FINISHED flag. This SSLeay | |
1058 | era flag was never set throughout the codebase (only read). Also removed | |
1059 | SSL3_FLAGS_POP_BUFFER which was only used if | |
1060 | SSL3_FLAGS_DELAY_CLIENT_FINISHED was also set. | |
1061 | [Matt Caswell] | |
1062 | ||
1063 | *) Changed the default name options in the "ca", "crl", "req" and "x509" | |
1064 | to be "oneline" instead of "compat". | |
1065 | [Richard Levitte] | |
1066 | ||
1067 | *) Remove SSL_OP_TLS_BLOCK_PADDING_BUG. This is SSLeay legacy, we're | |
1068 | not aware of clients that still exhibit this bug, and the workaround | |
1069 | hasn't been working properly for a while. | |
1070 | [Emilia Käsper] | |
1071 | ||
1072 | *) The return type of BIO_number_read() and BIO_number_written() as well as | |
1073 | the corresponding num_read and num_write members in the BIO structure has | |
1074 | changed from unsigned long to uint64_t. On platforms where an unsigned | |
1075 | long is 32 bits (e.g. Windows) these counters could overflow if >4Gb is | |
1076 | transferred. | |
1077 | [Matt Caswell] | |
1078 | ||
1079 | *) Given the pervasive nature of TLS extensions it is inadvisable to run | |
1080 | OpenSSL without support for them. It also means that maintaining | |
1081 | the OPENSSL_NO_TLSEXT option within the code is very invasive (and probably | |
1082 | not well tested). Therefore the OPENSSL_NO_TLSEXT option has been removed. | |
1083 | [Matt Caswell] | |
1084 | ||
1085 | *) Removed support for the two export grade static DH ciphersuites | |
1086 | EXP-DH-RSA-DES-CBC-SHA and EXP-DH-DSS-DES-CBC-SHA. These two ciphersuites | |
1087 | were newly added (along with a number of other static DH ciphersuites) to | |
1088 | 1.0.2. However the two export ones have *never* worked since they were | |
1089 | introduced. It seems strange in any case to be adding new export | |
1090 | ciphersuites, and given "logjam" it also does not seem correct to fix them. | |
1091 | [Matt Caswell] | |
1092 | ||
1093 | *) Version negotiation has been rewritten. In particular SSLv23_method(), | |
1094 | SSLv23_client_method() and SSLv23_server_method() have been deprecated, | |
1095 | and turned into macros which simply call the new preferred function names | |
1096 | TLS_method(), TLS_client_method() and TLS_server_method(). All new code | |
1097 | should use the new names instead. Also as part of this change the ssl23.h | |
1098 | header file has been removed. | |
1099 | [Matt Caswell] | |
1100 | ||
1101 | *) Support for Kerberos ciphersuites in TLS (RFC2712) has been removed. This | |
1102 | code and the associated standard is no longer considered fit-for-purpose. | |
1103 | [Matt Caswell] | |
1104 | ||
1105 | *) RT2547 was closed. When generating a private key, try to make the | |
1106 | output file readable only by the owner. This behavior change might | |
1107 | be noticeable when interacting with other software. | |
1108 | ||
1109 | *) Documented all exdata functions. Added CRYPTO_free_ex_index. | |
1110 | Added a test. | |
1111 | [Rich Salz] | |
1112 | ||
1113 | *) Added HTTP GET support to the ocsp command. | |
1114 | [Rich Salz] | |
1115 | ||
1116 | *) Changed default digest for the dgst and enc commands from MD5 to | |
1117 | sha256 | |
1118 | [Rich Salz] | |
1119 | ||
1120 | *) RAND_pseudo_bytes has been deprecated. Users should use RAND_bytes instead. | |
1121 | [Matt Caswell] | |
1122 | ||
1123 | *) Added support for TLS extended master secret from | |
1124 | draft-ietf-tls-session-hash-03.txt. Thanks for Alfredo Pironti for an | |
1125 | initial patch which was a great help during development. | |
1126 | [Steve Henson] | |
1127 | ||
1128 | *) All libssl internal structures have been removed from the public header | |
1129 | files, and the OPENSSL_NO_SSL_INTERN option has been removed (since it is | |
1130 | now redundant). Users should not attempt to access internal structures | |
1131 | directly. Instead they should use the provided API functions. | |
1132 | [Matt Caswell] | |
1133 | ||
1134 | *) config has been changed so that by default OPENSSL_NO_DEPRECATED is used. | |
1135 | Access to deprecated functions can be re-enabled by running config with | |
1136 | "enable-deprecated". In addition applications wishing to use deprecated | |
1137 | functions must define OPENSSL_USE_DEPRECATED. Note that this new behaviour | |
1138 | will, by default, disable some transitive includes that previously existed | |
1139 | in the header files (e.g. ec.h will no longer, by default, include bn.h) | |
1140 | [Matt Caswell] | |
1141 | ||
1142 | *) Added support for OCB mode. OpenSSL has been granted a patent license | |
1143 | compatible with the OpenSSL license for use of OCB. Details are available | |
1144 | at https://www.openssl.org/source/OCB-patent-grant-OpenSSL.pdf. Support | |
1145 | for OCB can be removed by calling config with no-ocb. | |
1146 | [Matt Caswell] | |
1147 | ||
1148 | *) SSLv2 support has been removed. It still supports receiving a SSLv2 | |
1149 | compatible client hello. | |
1150 | [Kurt Roeckx] | |
1151 | ||
1152 | *) Increased the minimal RSA keysize from 256 to 512 bits [Rich Salz], | |
1153 | done while fixing the error code for the key-too-small case. | |
1154 | [Annie Yousar <a.yousar@informatik.hu-berlin.de>] | |
1155 | ||
1156 | *) CA.sh has been removed; use CA.pl instead. | |
1157 | [Rich Salz] | |
1158 | ||
1159 | *) Removed old DES API. | |
1160 | [Rich Salz] | |
1161 | ||
1162 | *) Remove various unsupported platforms: | |
1163 | Sony NEWS4 | |
1164 | BEOS and BEOS_R5 | |
1165 | NeXT | |
1166 | SUNOS | |
1167 | MPE/iX | |
1168 | Sinix/ReliantUNIX RM400 | |
1169 | DGUX | |
1170 | NCR | |
1171 | Tandem | |
1172 | Cray | |
1173 | 16-bit platforms such as WIN16 | |
1174 | [Rich Salz] | |
1175 | ||
1176 | *) Clean up OPENSSL_NO_xxx #define's | |
1177 | Use setbuf() and remove OPENSSL_NO_SETVBUF_IONBF | |
1178 | Rename OPENSSL_SYSNAME_xxx to OPENSSL_SYS_xxx | |
1179 | OPENSSL_NO_EC{DH,DSA} merged into OPENSSL_NO_EC | |
1180 | OPENSSL_NO_RIPEMD160, OPENSSL_NO_RIPEMD merged into OPENSSL_NO_RMD160 | |
1181 | OPENSSL_NO_FP_API merged into OPENSSL_NO_STDIO | |
1182 | Remove OPENSSL_NO_BIO OPENSSL_NO_BUFFER OPENSSL_NO_CHAIN_VERIFY | |
1183 | OPENSSL_NO_EVP OPENSSL_NO_FIPS_ERR OPENSSL_NO_HASH_COMP | |
1184 | OPENSSL_NO_LHASH OPENSSL_NO_OBJECT OPENSSL_NO_SPEED OPENSSL_NO_STACK | |
1185 | OPENSSL_NO_X509 OPENSSL_NO_X509_VERIFY | |
1186 | Remove MS_STATIC; it's a relic from platforms <32 bits. | |
1187 | [Rich Salz] | |
1188 | ||
1189 | *) Cleaned up dead code | |
1190 | Remove all but one '#ifdef undef' which is to be looked at. | |
1191 | [Rich Salz] | |
1192 | ||
1193 | *) Clean up calling of xxx_free routines. | |
1194 | Just like free(), fix most of the xxx_free routines to accept | |
1195 | NULL. Remove the non-null checks from callers. Save much code. | |
1196 | [Rich Salz] | |
1197 | ||
1198 | *) Add secure heap for storage of private keys (when possible). | |
1199 | Add BIO_s_secmem(), CBIGNUM, etc. | |
1200 | Contributed by Akamai Technologies under our Corporate CLA. | |
1201 | [Rich Salz] | |
1202 | ||
1203 | *) Experimental support for a new, fast, unbiased prime candidate generator, | |
1204 | bn_probable_prime_dh_coprime(). Not currently used by any prime generator. | |
1205 | [Felix Laurie von Massenbach <felix@erbridge.co.uk>] | |
1206 | ||
1207 | *) New output format NSS in the sess_id command line tool. This allows | |
1208 | exporting the session id and the master key in NSS keylog format. | |
1209 | [Martin Kaiser <martin@kaiser.cx>] | |
1210 | ||
1211 | *) Harmonize version and its documentation. -f flag is used to display | |
1212 | compilation flags. | |
1213 | [mancha <mancha1@zoho.com>] | |
1214 | ||
1215 | *) Fix eckey_priv_encode so it immediately returns an error upon a failure | |
1216 | in i2d_ECPrivateKey. Thanks to Ted Unangst for feedback on this issue. | |
1217 | [mancha <mancha1@zoho.com>] | |
1218 | ||
1219 | *) Fix some double frees. These are not thought to be exploitable. | |
1220 | [mancha <mancha1@zoho.com>] | |
1221 | ||
1222 | *) A missing bounds check in the handling of the TLS heartbeat extension | |
1223 | can be used to reveal up to 64k of memory to a connected client or | |
1224 | server. | |
1225 | ||
1226 | Thanks for Neel Mehta of Google Security for discovering this bug and to | |
1227 | Adam Langley <agl@chromium.org> and Bodo Moeller <bmoeller@acm.org> for | |
1228 | preparing the fix (CVE-2014-0160) | |
1229 | [Adam Langley, Bodo Moeller] | |
1230 | ||
1231 | *) Fix for the attack described in the paper "Recovering OpenSSL | |
1232 | ECDSA Nonces Using the FLUSH+RELOAD Cache Side-channel Attack" | |
1233 | by Yuval Yarom and Naomi Benger. Details can be obtained from: | |
1234 | http://eprint.iacr.org/2014/140 | |
1235 | ||
1236 | Thanks to Yuval Yarom and Naomi Benger for discovering this | |
1237 | flaw and to Yuval Yarom for supplying a fix (CVE-2014-0076) | |
1238 | [Yuval Yarom and Naomi Benger] | |
1239 | ||
1240 | *) Use algorithm specific chains in SSL_CTX_use_certificate_chain_file(): | |
1241 | this fixes a limitation in previous versions of OpenSSL. | |
1242 | [Steve Henson] | |
1243 | ||
1244 | *) Experimental encrypt-then-mac support. | |
1245 | ||
1246 | Experimental support for encrypt then mac from | |
1247 | draft-gutmann-tls-encrypt-then-mac-02.txt | |
1248 | ||
1249 | To enable it set the appropriate extension number (0x42 for the test | |
1250 | server) using e.g. -DTLSEXT_TYPE_encrypt_then_mac=0x42 | |
1251 | ||
1252 | For non-compliant peers (i.e. just about everything) this should have no | |
1253 | effect. | |
1254 | ||
1255 | WARNING: EXPERIMENTAL, SUBJECT TO CHANGE. | |
1256 | ||
1257 | [Steve Henson] | |
1258 | ||
1259 | *) Add EVP support for key wrapping algorithms, to avoid problems with | |
1260 | existing code the flag EVP_CIPHER_CTX_WRAP_ALLOW has to be set in | |
1261 | the EVP_CIPHER_CTX or an error is returned. Add AES and DES3 wrap | |
1262 | algorithms and include tests cases. | |
1263 | [Steve Henson] | |
1264 | ||
1265 | *) Extend CMS code to support RSA-PSS signatures and RSA-OAEP for | |
1266 | enveloped data. | |
1267 | [Steve Henson] | |
1268 | ||
1269 | *) Extended RSA OAEP support via EVP_PKEY API. Options to specify digest, | |
1270 | MGF1 digest and OAEP label. | |
1271 | [Steve Henson] | |
1272 | ||
1273 | *) Make openssl verify return errors. | |
1274 | [Chris Palmer <palmer@google.com> and Ben Laurie] | |
1275 | ||
1276 | *) New function ASN1_TIME_diff to calculate the difference between two | |
1277 | ASN1_TIME structures or one structure and the current time. | |
1278 | [Steve Henson] | |
1279 | ||
1280 | *) Update fips_test_suite to support multiple command line options. New | |
1281 | test to induce all self test errors in sequence and check expected | |
1282 | failures. | |
1283 | [Steve Henson] | |
1284 | ||
1285 | *) Add FIPS_{rsa,dsa,ecdsa}_{sign,verify} functions which digest and | |
1286 | sign or verify all in one operation. | |
1287 | [Steve Henson] | |
1288 | ||
1289 | *) Add fips_algvs: a multicall fips utility incorporating all the algorithm | |
1290 | test programs and fips_test_suite. Includes functionality to parse | |
1291 | the minimal script output of fipsalgest.pl directly. | |
1292 | [Steve Henson] | |
1293 | ||
1294 | *) Add authorisation parameter to FIPS_module_mode_set(). | |
1295 | [Steve Henson] | |
1296 | ||
1297 | *) Add FIPS selftest for ECDH algorithm using P-224 and B-233 curves. | |
1298 | [Steve Henson] | |
1299 | ||
1300 | *) Use separate DRBG fields for internal and external flags. New function | |
1301 | FIPS_drbg_health_check() to perform on demand health checking. Add | |
1302 | generation tests to fips_test_suite with reduced health check interval to | |
1303 | demonstrate periodic health checking. Add "nodh" option to | |
1304 | fips_test_suite to skip very slow DH test. | |
1305 | [Steve Henson] | |
1306 | ||
1307 | *) New function FIPS_get_cipherbynid() to lookup FIPS supported ciphers | |
1308 | based on NID. | |
1309 | [Steve Henson] | |
1310 | ||
1311 | *) More extensive health check for DRBG checking many more failure modes. | |
1312 | New function FIPS_selftest_drbg_all() to handle every possible DRBG | |
1313 | combination: call this in fips_test_suite. | |
1314 | [Steve Henson] | |
1315 | ||
1316 | *) Add support for canonical generation of DSA parameter 'g'. See | |
1317 | FIPS 186-3 A.2.3. | |
1318 | ||
1319 | *) Add support for HMAC DRBG from SP800-90. Update DRBG algorithm test and | |
1320 | POST to handle HMAC cases. | |
1321 | [Steve Henson] | |
1322 | ||
1323 | *) Add functions FIPS_module_version() and FIPS_module_version_text() | |
1324 | to return numerical and string versions of the FIPS module number. | |
1325 | [Steve Henson] | |
1326 | ||
1327 | *) Rename FIPS_mode_set and FIPS_mode to FIPS_module_mode_set and | |
1328 | FIPS_module_mode. FIPS_mode and FIPS_mode_set will be implemented | |
1329 | outside the validated module in the FIPS capable OpenSSL. | |
1330 | [Steve Henson] | |
1331 | ||
1332 | *) Minor change to DRBG entropy callback semantics. In some cases | |
1333 | there is no multiple of the block length between min_len and | |
1334 | max_len. Allow the callback to return more than max_len bytes | |
1335 | of entropy but discard any extra: it is the callback's responsibility | |
1336 | to ensure that the extra data discarded does not impact the | |
1337 | requested amount of entropy. | |
1338 | [Steve Henson] | |
1339 | ||
1340 | *) Add PRNG security strength checks to RSA, DSA and ECDSA using | |
1341 | information in FIPS186-3, SP800-57 and SP800-131A. | |
1342 | [Steve Henson] | |
1343 | ||
1344 | *) CCM support via EVP. Interface is very similar to GCM case except we | |
1345 | must supply all data in one chunk (i.e. no update, final) and the | |
1346 | message length must be supplied if AAD is used. Add algorithm test | |
1347 | support. | |
1348 | [Steve Henson] | |
1349 | ||
1350 | *) Initial version of POST overhaul. Add POST callback to allow the status | |
1351 | of POST to be monitored and/or failures induced. Modify fips_test_suite | |
1352 | to use callback. Always run all selftests even if one fails. | |
1353 | [Steve Henson] | |
1354 | ||
1355 | *) XTS support including algorithm test driver in the fips_gcmtest program. | |
1356 | Note: this does increase the maximum key length from 32 to 64 bytes but | |
1357 | there should be no binary compatibility issues as existing applications | |
1358 | will never use XTS mode. | |
1359 | [Steve Henson] | |
1360 | ||
1361 | *) Extensive reorganisation of FIPS PRNG behaviour. Remove all dependencies | |
1362 | to OpenSSL RAND code and replace with a tiny FIPS RAND API which also | |
1363 | performs algorithm blocking for unapproved PRNG types. Also do not | |
1364 | set PRNG type in FIPS_mode_set(): leave this to the application. | |
1365 | Add default OpenSSL DRBG handling: sets up FIPS PRNG and seeds with | |
1366 | the standard OpenSSL PRNG: set additional data to a date time vector. | |
1367 | [Steve Henson] | |
1368 | ||
1369 | *) Rename old X9.31 PRNG functions of the form FIPS_rand* to FIPS_x931*. | |
1370 | This shouldn't present any incompatibility problems because applications | |
1371 | shouldn't be using these directly and any that are will need to rethink | |
1372 | anyway as the X9.31 PRNG is now deprecated by FIPS 140-2 | |
1373 | [Steve Henson] | |
1374 | ||
1375 | *) Extensive self tests and health checking required by SP800-90 DRBG. | |
1376 | Remove strength parameter from FIPS_drbg_instantiate and always | |
1377 | instantiate at maximum supported strength. | |
1378 | [Steve Henson] | |
1379 | ||
1380 | *) Add ECDH code to fips module and fips_ecdhvs for primitives only testing. | |
1381 | [Steve Henson] | |
1382 | ||
1383 | *) New algorithm test program fips_dhvs to handle DH primitives only testing. | |
1384 | [Steve Henson] | |
1385 | ||
1386 | *) New function DH_compute_key_padded() to compute a DH key and pad with | |
1387 | leading zeroes if needed: this complies with SP800-56A et al. | |
1388 | [Steve Henson] | |
1389 | ||
1390 | *) Initial implementation of SP800-90 DRBGs for Hash and CTR. Not used by | |
1391 | anything, incomplete, subject to change and largely untested at present. | |
1392 | [Steve Henson] | |
1393 | ||
1394 | *) Modify fipscanisteronly build option to only build the necessary object | |
1395 | files by filtering FIPS_EX_OBJ through a perl script in crypto/Makefile. | |
1396 | [Steve Henson] | |
1397 | ||
1398 | *) Add experimental option FIPSSYMS to give all symbols in | |
1399 | fipscanister.o and FIPS or fips prefix. This will avoid | |
1400 | conflicts with future versions of OpenSSL. Add perl script | |
1401 | util/fipsas.pl to preprocess assembly language source files | |
1402 | and rename any affected symbols. | |
1403 | [Steve Henson] | |
1404 | ||
1405 | *) Add selftest checks and algorithm block of non-fips algorithms in | |
1406 | FIPS mode. Remove DES2 from selftests. | |
1407 | [Steve Henson] | |
1408 | ||
1409 | *) Add ECDSA code to fips module. Add tiny fips_ecdsa_check to just | |
1410 | return internal method without any ENGINE dependencies. Add new | |
1411 | tiny fips sign and verify functions. | |
1412 | [Steve Henson] | |
1413 | ||
1414 | *) New build option no-ec2m to disable characteristic 2 code. | |
1415 | [Steve Henson] | |
1416 | ||
1417 | *) New build option "fipscanisteronly". This only builds fipscanister.o | |
1418 | and (currently) associated fips utilities. Uses the file Makefile.fips | |
1419 | instead of Makefile.org as the prototype. | |
1420 | [Steve Henson] | |
1421 | ||
1422 | *) Add some FIPS mode restrictions to GCM. Add internal IV generator. | |
1423 | Update fips_gcmtest to use IV generator. | |
1424 | [Steve Henson] | |
1425 | ||
1426 | *) Initial, experimental EVP support for AES-GCM. AAD can be input by | |
1427 | setting output buffer to NULL. The *Final function must be | |
1428 | called although it will not retrieve any additional data. The tag | |
1429 | can be set or retrieved with a ctrl. The IV length is by default 12 | |
1430 | bytes (96 bits) but can be set to an alternative value. If the IV | |
1431 | length exceeds the maximum IV length (currently 16 bytes) it cannot be | |
1432 | set before the key. | |
1433 | [Steve Henson] | |
1434 | ||
1435 | *) New flag in ciphers: EVP_CIPH_FLAG_CUSTOM_CIPHER. This means the | |
1436 | underlying do_cipher function handles all cipher semantics itself | |
1437 | including padding and finalisation. This is useful if (for example) | |
1438 | an ENGINE cipher handles block padding itself. The behaviour of | |
1439 | do_cipher is subtly changed if this flag is set: the return value | |
1440 | is the number of characters written to the output buffer (zero is | |
1441 | no longer an error code) or a negative error code. Also if the | |
1442 | input buffer is NULL and length 0 finalisation should be performed. | |
1443 | [Steve Henson] | |
1444 | ||
1445 | *) If a candidate issuer certificate is already part of the constructed | |
1446 | path ignore it: new debug notification X509_V_ERR_PATH_LOOP for this case. | |
1447 | [Steve Henson] | |
1448 | ||
1449 | *) Improve forward-security support: add functions | |
1450 | ||
1451 | void SSL_CTX_set_not_resumable_session_callback(SSL_CTX *ctx, int (*cb)(SSL *ssl, int is_forward_secure)) | |
1452 | void SSL_set_not_resumable_session_callback(SSL *ssl, int (*cb)(SSL *ssl, int is_forward_secure)) | |
1453 | ||
1454 | for use by SSL/TLS servers; the callback function will be called whenever a | |
1455 | new session is created, and gets to decide whether the session may be | |
1456 | cached to make it resumable (return 0) or not (return 1). (As by the | |
1457 | SSL/TLS protocol specifications, the session_id sent by the server will be | |
1458 | empty to indicate that the session is not resumable; also, the server will | |
1459 | not generate RFC 4507 (RFC 5077) session tickets.) | |
1460 | ||
1461 | A simple reasonable callback implementation is to return is_forward_secure. | |
1462 | This parameter will be set to 1 or 0 depending on the ciphersuite selected | |
1463 | by the SSL/TLS server library, indicating whether it can provide forward | |
1464 | security. | |
1465 | [Emilia Käsper <emilia.kasper@esat.kuleuven.be> (Google)] | |
1466 | ||
1467 | *) New -verify_name option in command line utilities to set verification | |
1468 | parameters by name. | |
1469 | [Steve Henson] | |
1470 | ||
1471 | *) Initial CMAC implementation. WARNING: EXPERIMENTAL, API MAY CHANGE. | |
1472 | Add CMAC pkey methods. | |
1473 | [Steve Henson] | |
1474 | ||
1475 | *) Experimental renegotiation in s_server -www mode. If the client | |
1476 | browses /reneg connection is renegotiated. If /renegcert it is | |
1477 | renegotiated requesting a certificate. | |
1478 | [Steve Henson] | |
1479 | ||
1480 | *) Add an "external" session cache for debugging purposes to s_server. This | |
1481 | should help trace issues which normally are only apparent in deployed | |
1482 | multi-process servers. | |
1483 | [Steve Henson] | |
1484 | ||
1485 | *) Extensive audit of libcrypto with DEBUG_UNUSED. Fix many cases where | |
1486 | return value is ignored. NB. The functions RAND_add(), RAND_seed(), | |
1487 | BIO_set_cipher() and some obscure PEM functions were changed so they | |
1488 | can now return an error. The RAND changes required a change to the | |
1489 | RAND_METHOD structure. | |
1490 | [Steve Henson] | |
1491 | ||
1492 | *) New macro __owur for "OpenSSL Warn Unused Result". This makes use of | |
1493 | a gcc attribute to warn if the result of a function is ignored. This | |
1494 | is enable if DEBUG_UNUSED is set. Add to several functions in evp.h | |
1495 | whose return value is often ignored. | |
1496 | [Steve Henson] | |
1497 | ||
1498 | *) New -noct, -requestct, -requirect and -ctlogfile options for s_client. | |
1499 | These allow SCTs (signed certificate timestamps) to be requested and | |
1500 | validated when establishing a connection. | |

1503 | Changes between 1.0.2g and 1.0.2h [3 May 2016] | |
1504 | ||
1505 | *) Prevent padding oracle in AES-NI CBC MAC check | |
1506 | ||
1507 | A MITM attacker can use a padding oracle attack to decrypt traffic | |
1508 | when the connection uses an AES CBC cipher and the server support | |
1509 | AES-NI. | |
1510 | ||
1511 | This issue was introduced as part of the fix for Lucky 13 padding | |
1512 | attack (CVE-2013-0169). The padding check was rewritten to be in | |
1513 | constant time by making sure that always the same bytes are read and | |
1514 | compared against either the MAC or padding bytes. But it no longer | |
1515 | checked that there was enough data to have both the MAC and padding | |
1516 | bytes. | |
1517 | ||
1518 | This issue was reported by Juraj Somorovsky using TLS-Attacker. | |
1519 | (CVE-2016-2107) | |
1520 | [Kurt Roeckx] | |
1521 | ||
1522 | *) Fix EVP_EncodeUpdate overflow | |
1523 | ||
1524 | An overflow can occur in the EVP_EncodeUpdate() function which is used for | |
1525 | Base64 encoding of binary data. If an attacker is able to supply very large | |
1526 | amounts of input data then a length check can overflow resulting in a heap | |
1527 | corruption. | |
1528 | ||
1529 | Internally to OpenSSL the EVP_EncodeUpdate() function is primarily used by | |
1530 | the PEM_write_bio* family of functions. These are mainly used within the | |
1531 | OpenSSL command line applications, so any application which processes data | |
1532 | from an untrusted source and outputs it as a PEM file should be considered | |
1533 | vulnerable to this issue. User applications that call these APIs directly | |
1534 | with large amounts of untrusted data may also be vulnerable. | |
1535 | ||
1536 | This issue was reported by Guido Vranken. | |
1537 | (CVE-2016-2105) | |
1538 | [Matt Caswell] | |
1539 | ||
1540 | *) Fix EVP_EncryptUpdate overflow | |
1541 | ||
1542 | An overflow can occur in the EVP_EncryptUpdate() function. If an attacker | |
1543 | is able to supply very large amounts of input data after a previous call to | |
1544 | EVP_EncryptUpdate() with a partial block then a length check can overflow | |
1545 | resulting in a heap corruption. Following an analysis of all OpenSSL | |
1546 | internal usage of the EVP_EncryptUpdate() function all usage is one of two | |
1547 | forms. The first form is where the EVP_EncryptUpdate() call is known to be | |
1548 | the first called function after an EVP_EncryptInit(), and therefore that | |
1549 | specific call must be safe. The second form is where the length passed to | |
1550 | EVP_EncryptUpdate() can be seen from the code to be some small value and | |
1551 | therefore there is no possibility of an overflow. Since all instances are | |
1552 | one of these two forms, it is believed that there can be no overflows in | |
1553 | internal code due to this problem. It should be noted that | |
1554 | EVP_DecryptUpdate() can call EVP_EncryptUpdate() in certain code paths. | |
1555 | Also EVP_CipherUpdate() is a synonym for EVP_EncryptUpdate(). All instances | |
1556 | of these calls have also been analysed too and it is believed there are no | |
1557 | instances in internal usage where an overflow could occur. | |
1558 | ||
1559 | This issue was reported by Guido Vranken. | |
1560 | (CVE-2016-2106) | |
1561 | [Matt Caswell] | |
1562 | ||
1563 | *) Prevent ASN.1 BIO excessive memory allocation | |
1564 | ||
1565 | When ASN.1 data is read from a BIO using functions such as d2i_CMS_bio() | |
1566 | a short invalid encoding can cause allocation of large amounts of memory | |
1567 | potentially consuming excessive resources or exhausting memory. | |
1568 | ||
1569 | Any application parsing untrusted data through d2i BIO functions is | |
1570 | affected. The memory based functions such as d2i_X509() are *not* affected. | |
1571 | Since the memory based functions are used by the TLS library, TLS | |
1572 | applications are not affected. | |
1573 | ||
1574 | This issue was reported by Brian Carpenter. | |
1575 | (CVE-2016-2109) | |
1576 | [Stephen Henson] | |
1577 | ||
1578 | *) EBCDIC overread | |
1579 | ||
1580 | ASN1 Strings that are over 1024 bytes can cause an overread in applications | |
1581 | using the X509_NAME_oneline() function on EBCDIC systems. This could result | |
1582 | in arbitrary stack data being returned in the buffer. | |
1583 | ||
1584 | This issue was reported by Guido Vranken. | |
1585 | (CVE-2016-2176) | |
1586 | [Matt Caswell] | |
1587 | ||
1588 | *) Modify behavior of ALPN to invoke callback after SNI/servername | |
1589 | callback, such that updates to the SSL_CTX affect ALPN. | |
1590 | [Todd Short] | |
1591 | ||
1592 | *) Remove LOW from the DEFAULT cipher list. This removes singles DES from the | |
1593 | default. | |
1594 | [Kurt Roeckx] | |
1595 | ||
1596 | *) Only remove the SSLv2 methods with the no-ssl2-method option. When the | |
1597 | methods are enabled and ssl2 is disabled the methods return NULL. | |
1598 | [Kurt Roeckx] | |
1599 | ||
1600 | Changes between 1.0.2f and 1.0.2g [1 Mar 2016] | |
1601 | ||
1602 | * Disable weak ciphers in SSLv3 and up in default builds of OpenSSL. | |
1603 | Builds that are not configured with "enable-weak-ssl-ciphers" will not | |
1604 | provide any "EXPORT" or "LOW" strength ciphers. | |
1605 | [Viktor Dukhovni] | |
1606 | ||
1607 | * Disable SSLv2 default build, default negotiation and weak ciphers. SSLv2 | |
1608 | is by default disabled at build-time. Builds that are not configured with | |
1609 | "enable-ssl2" will not support SSLv2. Even if "enable-ssl2" is used, | |
1610 | users who want to negotiate SSLv2 via the version-flexible SSLv23_method() | |
1611 | will need to explicitly call either of: | |
1612 | ||
1613 | SSL_CTX_clear_options(ctx, SSL_OP_NO_SSLv2); | |
1614 | or | |
1615 | SSL_clear_options(ssl, SSL_OP_NO_SSLv2); | |
1616 | ||
1617 | as appropriate. Even if either of those is used, or the application | |
1618 | explicitly uses the version-specific SSLv2_method() or its client and | |
1619 | server variants, SSLv2 ciphers vulnerable to exhaustive search key | |
1620 | recovery have been removed. Specifically, the SSLv2 40-bit EXPORT | |
1621 | ciphers, and SSLv2 56-bit DES are no longer available. | |

1623 | [Viktor Dukhovni] | |
1624 | ||
1625 | *) Fix a double-free in DSA code | |
1626 | ||
1627 | A double free bug was discovered when OpenSSL parses malformed DSA private | |
1628 | keys and could lead to a DoS attack or memory corruption for applications | |
1629 | that receive DSA private keys from untrusted sources. This scenario is | |
1630 | considered rare. | |
1631 | ||
1632 | This issue was reported to OpenSSL by Adam Langley(Google/BoringSSL) using | |
1633 | libFuzzer. | |
1634 | (CVE-2016-0705) | |
1635 | [Stephen Henson] | |
1636 | ||
1637 | *) Disable SRP fake user seed to address a server memory leak. | |
1638 | ||
1639 | Add a new method SRP_VBASE_get1_by_user that handles the seed properly. | |
1640 | ||
1641 | SRP_VBASE_get_by_user had inconsistent memory management behaviour. | |
1642 | In order to fix an unavoidable memory leak, SRP_VBASE_get_by_user | |
1643 | was changed to ignore the "fake user" SRP seed, even if the seed | |
1644 | is configured. | |
1645 | ||
1646 | Users should use SRP_VBASE_get1_by_user instead. Note that in | |
1647 | SRP_VBASE_get1_by_user, caller must free the returned value. Note | |
1648 | also that even though configuring the SRP seed attempts to hide | |
1649 | invalid usernames by continuing the handshake with fake | |
1650 | credentials, this behaviour is not constant time and no strong | |
1651 | guarantees are made that the handshake is indistinguishable from | |
1652 | that of a valid user. | |
1653 | (CVE-2016-0798) | |
1654 | [Emilia Käsper] | |
1655 | ||
1656 | *) Fix BN_hex2bn/BN_dec2bn NULL pointer deref/heap corruption | |
1657 | ||
1658 | In the BN_hex2bn function the number of hex digits is calculated using an | |
1659 | int value |i|. Later |bn_expand| is called with a value of |i * 4|. For | |
1660 | large values of |i| this can result in |bn_expand| not allocating any | |
1661 | memory because |i * 4| is negative. This can leave the internal BIGNUM data | |
1662 | field as NULL leading to a subsequent NULL ptr deref. For very large values | |
1663 | of |i|, the calculation |i * 4| could be a positive value smaller than |i|. | |
1664 | In this case memory is allocated to the internal BIGNUM data field, but it | |
1665 | is insufficiently sized leading to heap corruption. A similar issue exists | |
1666 | in BN_dec2bn. This could have security consequences if BN_hex2bn/BN_dec2bn | |
1667 | is ever called by user applications with very large untrusted hex/dec data. | |
1668 | This is anticipated to be a rare occurrence. | |
1669 | ||
1670 | All OpenSSL internal usage of these functions use data that is not expected | |
1671 | to be untrusted, e.g. config file data or application command line | |
1672 | arguments. If user developed applications generate config file data based | |
1673 | on untrusted data then it is possible that this could also lead to security | |
1674 | consequences. This is also anticipated to be rare. | |
1675 | ||
1676 | This issue was reported to OpenSSL by Guido Vranken. | |
1677 | (CVE-2016-0797) | |
1678 | [Matt Caswell] | |
1679 | ||
1680 | *) Fix memory issues in BIO_*printf functions | |
1681 | ||
1682 | The internal |fmtstr| function used in processing a "%s" format string in | |
1683 | the BIO_*printf functions could overflow while calculating the length of a | |
1684 | string and cause an OOB read when printing very long strings. | |
1685 | ||
1686 | Additionally the internal |doapr_outch| function can attempt to write to an | |
1687 | OOB memory location (at an offset from the NULL pointer) in the event of a | |
1688 | memory allocation failure. In 1.0.2 and below this could be caused where | |
1689 | the size of a buffer to be allocated is greater than INT_MAX. E.g. this | |
1690 | could be in processing a very long "%s" format string. Memory leaks can | |
1691 | also occur. | |
1692 | ||
1693 | The first issue may mask the second issue dependent on compiler behaviour. | |
1694 | These problems could enable attacks where large amounts of untrusted data | |
1695 | is passed to the BIO_*printf functions. If applications use these functions | |
1696 | in this way then they could be vulnerable. OpenSSL itself uses these | |
1697 | functions when printing out human-readable dumps of ASN.1 data. Therefore | |
1698 | applications that print this data could be vulnerable if the data is from | |
1699 | untrusted sources. OpenSSL command line applications could also be | |
1700 | vulnerable where they print out ASN.1 data, or if untrusted data is passed | |
1701 | as command line arguments. | |
1702 | ||
1703 | Libssl is not considered directly vulnerable. Additionally certificates etc | |
1704 | received via remote connections via libssl are also unlikely to be able to | |
1705 | trigger these issues because of message size limits enforced within libssl. | |
1706 | ||

1713 | A side-channel attack was found which makes use of cache-bank conflicts on | |
1714 | the Intel Sandy-Bridge microarchitecture which could lead to the recovery | |
1715 | of RSA keys. The ability to exploit this issue is limited as it relies on | |
1716 | an attacker who has control of code in a thread running on the same | |
1717 | hyper-threaded core as the victim thread which is performing decryptions. | |
1718 | ||
1719 | This issue was reported to OpenSSL by Yuval Yarom, The University of | |
1720 | Adelaide and NICTA, Daniel Genkin, Technion and Tel Aviv University, and | |
1721 | Nadia Heninger, University of Pennsylvania with more information at | |
1722 | http://cachebleed.info. | |
1723 | (CVE-2016-0702) | |
1724 | [Andy Polyakov] | |
1725 | ||
1726 | *) Change the req app to generate a 2048-bit RSA/DSA key by default, | |
1727 | if no keysize is specified with default_bits. This fixes an | |
1728 | omission in an earlier change that changed all RSA/DSA key generation | |
1729 | apps to use 2048 bits by default. | |

1732 | Changes between 1.0.2e and 1.0.2f [28 Jan 2016] | |
1733 | *) DH small subgroups | |
1734 | ||
1735 | Historically OpenSSL only ever generated DH parameters based on "safe" | |
1736 | primes. More recently (in version 1.0.2) support was provided for | |
1737 | generating X9.42 style parameter files such as those required for RFC 5114 | |
1738 | support. The primes used in such files may not be "safe". Where an | |
1739 | application is using DH configured with parameters based on primes that are | |
1740 | not "safe" then an attacker could use this fact to find a peer's private | |
1741 | DH exponent. This attack requires that the attacker complete multiple | |
1742 | handshakes in which the peer uses the same private DH exponent. For example | |
1743 | this could be used to discover a TLS server's private DH exponent if it's | |
1744 | reusing the private DH exponent or it's using a static DH ciphersuite. | |
1745 | ||
1746 | OpenSSL provides the option SSL_OP_SINGLE_DH_USE for ephemeral DH (DHE) in | |
1747 | TLS. It is not on by default. If the option is not set then the server | |
1748 | reuses the same private DH exponent for the life of the server process and | |
1749 | would be vulnerable to this attack. It is believed that many popular | |
1750 | applications do set this option and would therefore not be at risk. | |
1751 | ||
1752 | The fix for this issue adds an additional check where a "q" parameter is | |
1753 | available (as is the case in X9.42 based parameters). This detects the | |
1754 | only known attack, and is the only possible defense for static DH | |
1755 | ciphersuites. This could have some performance impact. | |
1756 | ||
1757 | Additionally the SSL_OP_SINGLE_DH_USE option has been switched on by | |
1758 | default and cannot be disabled. This could have some performance impact. | |
1759 | ||
1760 | This issue was reported to OpenSSL by Antonio Sanso (Adobe). | |
1761 | (CVE-2016-0701) | |
1762 | [Matt Caswell] | |
1763 | ||
1764 | *) SSLv2 doesn't block disabled ciphers | |
1765 | ||
1766 | A malicious client can negotiate SSLv2 ciphers that have been disabled on | |
1767 | the server and complete SSLv2 handshakes even if all SSLv2 ciphers have | |
1768 | been disabled, provided that the SSLv2 protocol was not also disabled via | |
1769 | SSL_OP_NO_SSLv2. | |
1770 | ||
1771 | This issue was reported to OpenSSL on 26th December 2015 by Nimrod Aviram | |
1772 | and Sebastian Schinzel. | |

1774 | [Viktor Dukhovni] | |
1775 | ||
1776 | Changes between 1.0.2d and 1.0.2e [3 Dec 2015] | |
1777 | ||
1778 | *) BN_mod_exp may produce incorrect results on x86_64 | |
1779 | ||
1780 | There is a carry propagating bug in the x86_64 Montgomery squaring | |
1781 | procedure. No EC algorithms are affected. Analysis suggests that attacks | |
1782 | against RSA and DSA as a result of this defect would be very difficult to | |
1783 | perform and are not believed likely. Attacks against DH are considered just | |
1784 | feasible (although very difficult) because most of the work necessary to | |
1785 | deduce information about a private key may be performed offline. The amount | |
1786 | of resources required for such an attack would be very significant and | |
1787 | likely only accessible to a limited number of attackers. An attacker would | |
1788 | additionally need online access to an unpatched system using the target | |
1789 | private key in a scenario with persistent DH parameters and a private | |
1790 | key that is shared between multiple clients. For example this can occur by | |
1791 | default in OpenSSL DHE based SSL/TLS ciphersuites. | |
1792 | ||
1793 | This issue was reported to OpenSSL by Hanno Böck. | |
1794 | (CVE-2015-3193) | |
1795 | [Andy Polyakov] | |
1796 | ||
1797 | *) Certificate verify crash with missing PSS parameter | |
1798 | ||
1799 | The signature verification routines will crash with a NULL pointer | |
1800 | dereference if presented with an ASN.1 signature using the RSA PSS | |
1801 | algorithm and absent mask generation function parameter. Since these | |
1802 | routines are used to verify certificate signature algorithms this can be | |
1803 | used to crash any certificate verification operation and exploited in a | |
1804 | DoS attack. Any application which performs certificate verification is | |
1805 | vulnerable including OpenSSL clients and servers which enable client | |
1806 | authentication. | |
1807 | ||
1808 | This issue was reported to OpenSSL by Loïc Jonas Etienne (Qnective AG). | |
1809 | (CVE-2015-3194) | |
1810 | [Stephen Henson] | |
1811 | ||
1812 | *) X509_ATTRIBUTE memory leak | |
1813 | ||
1814 | When presented with a malformed X509_ATTRIBUTE structure OpenSSL will leak | |
1815 | memory. This structure is used by the PKCS#7 and CMS routines so any | |
1816 | application which reads PKCS#7 or CMS data from untrusted sources is | |
1817 | affected. SSL/TLS is not affected. | |
1818 | ||
1819 | This issue was reported to OpenSSL by Adam Langley (Google/BoringSSL) using | |
1820 | libFuzzer. | |
1821 | (CVE-2015-3195) | |
1822 | [Stephen Henson] | |
1823 | ||
1824 | *) Rewrite EVP_DecodeUpdate (base64 decoding) to fix several bugs. | |
1825 | This changes the decoding behaviour for some invalid messages, | |
1826 | though the change is mostly in the more lenient direction, and | |
1827 | legacy behaviour is preserved as much as possible. | |
1828 | [Emilia Käsper] | |

1832 | [Rich Salz and Ismo Puustinen <ismo.puustinen@intel.com>] | |
1833 | ||
1834 | Changes between 1.0.2c and 1.0.2d [9 Jul 2015] | |
1835 | ||
1836 | *) Alternate chains certificate forgery | |
1837 | ||
1838 | During certificate verification, OpenSSL will attempt to find an | |
1839 | alternative certificate chain if the first attempt to build such a chain | |
1840 | fails. An error in the implementation of this logic can mean that an | |
1841 | attacker could cause certain checks on untrusted certificates to be | |
1842 | bypassed, such as the CA flag, enabling them to use a valid leaf | |
1843 | certificate to act as a CA and "issue" an invalid certificate. | |
1844 | ||
1845 | This issue was reported to OpenSSL by Adam Langley/David Benjamin | |
1846 | (Google/BoringSSL). | |
1847 | [Matt Caswell] | |
1848 | ||
1849 | Changes between 1.0.2b and 1.0.2c [12 Jun 2015] | |
1850 | ||
1851 | *) Fix HMAC ABI incompatibility. The previous version introduced an ABI | |
1852 | incompatibility in the handling of HMAC. The previous ABI has now been | |
1853 | restored. | |
1854 | [Matt Caswell] | |
1855 | ||
1856 | Changes between 1.0.2a and 1.0.2b [11 Jun 2015] | |
1857 | ||
1858 | *) Malformed ECParameters causes infinite loop | |
1859 | ||
1860 | When processing an ECParameters structure OpenSSL enters an infinite loop | |
1861 | if the curve specified is over a specially malformed binary polynomial | |
1862 | field. | |
1863 | ||
1864 | This can be used to perform denial of service against any | |
1865 | system which processes public keys, certificate requests or | |
1866 | certificates. This includes TLS clients and TLS servers with | |
1867 | client authentication enabled. | |
1868 | ||
1869 | This issue was reported to OpenSSL by Joseph Barr-Pixton. | |
1870 | (CVE-2015-1788) | |
1871 | [Andy Polyakov] | |
1872 | ||
1873 | *) Exploitable out-of-bounds read in X509_cmp_time | |
1874 | ||
1875 | X509_cmp_time does not properly check the length of the ASN1_TIME | |
1876 | string and can read a few bytes out of bounds. In addition, | |
1877 | X509_cmp_time accepts an arbitrary number of fractional seconds in the | |
1878 | time string. | |
1879 | ||
1880 | An attacker can use this to craft malformed certificates and CRLs of | |
1881 | various sizes and potentially cause a segmentation fault, resulting in | |
1882 | a DoS on applications that verify certificates or CRLs. TLS clients | |
1883 | that verify CRLs are affected. TLS clients and servers with client | |
1884 | authentication enabled may be affected if they use custom verification | |
1885 | callbacks. | |
1886 | ||
1887 | This issue was reported to OpenSSL by Robert Swiecki (Google), and | |
1888 | independently by Hanno Böck. | |
1889 | (CVE-2015-1789) | |
1890 | [Emilia Käsper] | |
1891 | ||
1892 | *) PKCS7 crash with missing EnvelopedContent | |
1893 | ||
1894 | The PKCS#7 parsing code does not handle missing inner EncryptedContent | |
1895 | correctly. An attacker can craft malformed ASN.1-encoded PKCS#7 blobs | |
1896 | with missing content and trigger a NULL pointer dereference on parsing. | |
1897 | ||
1898 | Applications that decrypt PKCS#7 data or otherwise parse PKCS#7 | |
1899 | structures from untrusted sources are affected. OpenSSL clients and | |
1900 | servers are not affected. | |
1901 | ||
1902 | This issue was reported to OpenSSL by Michal Zalewski (Google). | |
1903 | (CVE-2015-1790) | |
1904 | [Emilia Käsper] | |
1905 | ||
1906 | *) CMS verify infinite loop with unknown hash function | |
1907 | ||
1908 | When verifying a signedData message the CMS code can enter an infinite loop | |
1909 | if presented with an unknown hash function OID. This can be used to perform | |
1910 | denial of service against any system which verifies signedData messages using | |
1911 | the CMS code. | |
1912 | This issue was reported to OpenSSL by Johannes Bauer. | |
1913 | (CVE-2015-1792) | |
1914 | [Stephen Henson] | |
1915 | ||
1916 | *) Race condition handling NewSessionTicket | |
1917 | ||
1918 | If a NewSessionTicket is received by a multi-threaded client when attempting to | |
1919 | reuse a previous ticket then a race condition can occur potentially leading to | |
1920 | a double free of the ticket data. | |
1921 | (CVE-2015-1791) | |
1922 | [Matt Caswell] | |
1923 | ||
1924 | *) Only support 256-bit or stronger elliptic curves with the | |

1929 | Changes between 1.0.2 and 1.0.2a [19 Mar 2015] | |
1930 | ||
1931 | *) ClientHello sigalgs DoS fix | |
1932 | ||
1933 | If a client connects to an OpenSSL 1.0.2 server and renegotiates with an | |
1934 | invalid signature algorithms extension a NULL pointer dereference will | |
1935 | occur. This can be exploited in a DoS attack against the server. | |
1936 | ||
1937 | This issue was was reported to OpenSSL by David Ramos of Stanford | |
1938 | University. | |
1939 | (CVE-2015-0291) | |
1940 | [Stephen Henson and Matt Caswell] | |
1941 | ||
1942 | *) Multiblock corrupted pointer fix | |
1943 | ||
1944 | OpenSSL 1.0.2 introduced the "multiblock" performance improvement. This | |
1945 | feature only applies on 64 bit x86 architecture platforms that support AES | |
1946 | NI instructions. A defect in the implementation of "multiblock" can cause | |
1947 | OpenSSL's internal write buffer to become incorrectly set to NULL when | |
1948 | using non-blocking IO. Typically, when the user application is using a | |
1949 | socket BIO for writing, this will only result in a failed connection. | |
1950 | However if some other BIO is used then it is likely that a segmentation | |
1951 | fault will be triggered, thus enabling a potential DoS attack. | |
1952 | ||
1953 | This issue was reported to OpenSSL by Daniel Danner and Rainer Mueller. | |
1954 | (CVE-2015-0290) | |
1955 | [Matt Caswell] | |
1956 | ||
1957 | *) Segmentation fault in DTLSv1_listen fix | |
1958 | ||
1959 | The DTLSv1_listen function is intended to be stateless and processes the | |
1960 | initial ClientHello from many peers. It is common for user code to loop | |
1961 | over the call to DTLSv1_listen until a valid ClientHello is received with | |
1962 | an associated cookie. A defect in the implementation of DTLSv1_listen means | |
1963 | that state is preserved in the SSL object from one invocation to the next | |
1964 | that can lead to a segmentation fault. Errors processing the initial | |
1965 | ClientHello can trigger this scenario. An example of such an error could be | |
1966 | that a DTLS1.0 only client is attempting to connect to a DTLS1.2 only | |
1967 | server. | |
1968 | ||
1969 | This issue was reported to OpenSSL by Per Allansson. | |
1970 | (CVE-2015-0207) | |
1971 | [Matt Caswell] | |
1972 | ||
1973 | *) Segmentation fault in ASN1_TYPE_cmp fix | |
1974 | ||
1975 | The function ASN1_TYPE_cmp will crash with an invalid read if an attempt is | |
1976 | made to compare ASN.1 boolean types. Since ASN1_TYPE_cmp is used to check | |
1977 | certificate signature algorithm consistency this can be used to crash any | |
1978 | certificate verification operation and exploited in a DoS attack. Any | |
1979 | application which performs certificate verification is vulnerable including | |
1980 | OpenSSL clients and servers which enable client authentication. | |
1981 | (CVE-2015-0286) | |
1982 | [Stephen Henson] | |
1983 | ||
1984 | *) Segmentation fault for invalid PSS parameters fix | |
1985 | ||
1986 | The signature verification routines will crash with a NULL pointer | |
1987 | dereference if presented with an ASN.1 signature using the RSA PSS | |
1988 | algorithm and invalid parameters. Since these routines are used to verify | |
1989 | certificate signature algorithms this can be used to crash any | |
1990 | certificate verification operation and exploited in a DoS attack. Any | |
1991 | application which performs certificate verification is vulnerable including | |
1992 | OpenSSL clients and servers which enable client authentication. | |
1993 | ||
1994 | This issue was was reported to OpenSSL by Brian Carpenter. | |
1995 | (CVE-2015-0208) | |
1996 | [Stephen Henson] | |
1997 | ||
1998 | *) ASN.1 structure reuse memory corruption fix | |
1999 | ||
2000 | Reusing a structure in ASN.1 parsing may allow an attacker to cause | |
2001 | memory corruption via an invalid write. Such reuse is and has been | |
2002 | strongly discouraged and is believed to be rare. | |
2003 | ||
2004 | Applications that parse structures containing CHOICE or ANY DEFINED BY | |
2005 | components may be affected. Certificate parsing (d2i_X509 and related | |
2006 | functions) are however not affected. OpenSSL clients and servers are | |
2007 | not affected. | |
2008 | (CVE-2015-0287) | |
2009 | [Stephen Henson] | |
2010 | ||
2011 | *) PKCS7 NULL pointer dereferences fix | |
2012 | ||
2013 | The PKCS#7 parsing code does not handle missing outer ContentInfo | |
2014 | correctly. An attacker can craft malformed ASN.1-encoded PKCS#7 blobs with | |
2015 | missing content and trigger a NULL pointer dereference on parsing. | |
2016 | ||
2017 | Applications that verify PKCS#7 signatures, decrypt PKCS#7 data or | |
2018 | otherwise parse PKCS#7 structures from untrusted sources are | |
2019 | affected. OpenSSL clients and servers are not affected. | |
2020 | ||

2024 | ||
2025 | *) DoS via reachable assert in SSLv2 servers fix | |
2026 | ||
2027 | A malicious client can trigger an OPENSSL_assert (i.e., an abort) in | |
2028 | servers that both support SSLv2 and enable export cipher suites by sending | |
2029 | a specially crafted SSLv2 CLIENT-MASTER-KEY message. | |
2030 | ||
2031 | This issue was discovered by Sean Burford (Google) and Emilia Käsper | |
2032 | (OpenSSL development team). | |
2033 | (CVE-2015-0293) | |
2034 | [Emilia Käsper] | |
2035 | ||
2036 | *) Empty CKE with client auth and DHE fix | |
2037 | ||
2038 | If client auth is used then a server can seg fault in the event of a DHE | |
2039 | ciphersuite being selected and a zero length ClientKeyExchange message | |
2040 | being sent by the client. This could be exploited in a DoS attack. | |
2041 | (CVE-2015-1787) | |
2042 | [Matt Caswell] | |
2043 | ||
2044 | *) Handshake with unseeded PRNG fix | |
2045 | ||
2046 | Under certain conditions an OpenSSL 1.0.2 client can complete a handshake | |
2047 | with an unseeded PRNG. The conditions are: | |
2048 | - The client is on a platform where the PRNG has not been seeded | |
2049 | automatically, and the user has not seeded manually | |
2050 | - A protocol specific client method version has been used (i.e. not | |
2051 | SSL_client_methodv23) | |
2052 | - A ciphersuite is used that does not require additional random data from | |
2053 | the PRNG beyond the initial ClientHello client random (e.g. PSK-RC4-SHA). | |
2054 | ||
2055 | If the handshake succeeds then the client random that has been used will | |
2056 | have been generated from a PRNG with insufficient entropy and therefore the | |
2057 | output may be predictable. | |
2058 | ||
2059 | For example using the following command with an unseeded openssl will | |
2060 | succeed on an unpatched platform: | |
2061 | ||
2062 | openssl s_client -psk 1a2b3c4d -tls1_2 -cipher PSK-RC4-SHA | |
2063 | (CVE-2015-0285) | |
2064 | [Matt Caswell] | |
2065 | ||
2066 | *) Use After Free following d2i_ECPrivatekey error fix | |
2067 | ||
2068 | A malformed EC private key file consumed via the d2i_ECPrivateKey function | |
2069 | could cause a use after free condition. This, in turn, could cause a double | |
2070 | free in several private key parsing functions (such as d2i_PrivateKey | |
2071 | or EVP_PKCS82PKEY) and could lead to a DoS attack or memory corruption | |
2072 | for applications that receive EC private keys from untrusted | |
2073 | sources. This scenario is considered rare. | |
2074 | ||
2075 | This issue was discovered by the BoringSSL project and fixed in their | |
2076 | commit 517073cd4b. | |
2077 | (CVE-2015-0209) | |

2080 | *) X509_to_X509_REQ NULL pointer deref fix | |
2081 | ||
2082 | The function X509_to_X509_REQ will crash with a NULL pointer dereference if | |
2083 | the certificate key is invalid. This function is rarely used in practice. | |

2089 | *) Removed the export ciphers from the DEFAULT ciphers | |
2090 | [Kurt Roeckx] | |
2091 | ||
2092 | Changes between 1.0.1l and 1.0.2 [22 Jan 2015] | |
2093 | ||
2094 | *) Facilitate "universal" ARM builds targeting range of ARM ISAs, e.g. | |
2095 | ARMv5 through ARMv8, as opposite to "locking" it to single one. | |
2096 | So far those who have to target multiple platforms would compromise | |
2097 | and argue that binary targeting say ARMv5 would still execute on | |
2098 | ARMv8. "Universal" build resolves this compromise by providing | |
2099 | near-optimal performance even on newer platforms. | |
2100 | [Andy Polyakov] | |
2101 | ||
2102 | *) Accelerated NIST P-256 elliptic curve implementation for x86_64 | |
2103 | (other platforms pending). | |
2104 | [Shay Gueron & Vlad Krasnov (Intel Corp), Andy Polyakov] | |
2105 | ||
2106 | *) Add support for the SignedCertificateTimestampList certificate and | |
2107 | OCSP response extensions from RFC6962. | |
2108 | [Rob Stradling] | |
2109 | ||
2110 | *) Fix ec_GFp_simple_points_make_affine (thus, EC_POINTs_mul etc.) | |
2111 | for corner cases. (Certain input points at infinity could lead to | |
2112 | bogus results, with non-infinity inputs mapped to infinity too.) | |
2113 | [Bodo Moeller] | |
2114 | ||
2115 | *) Initial support for PowerISA 2.0.7, first implemented in POWER8. | |
2116 | This covers AES, SHA256/512 and GHASH. "Initial" means that most | |
2117 | common cases are optimized and there still is room for further | |
2118 | improvements. Vector Permutation AES for Altivec is also added. | |
2119 | [Andy Polyakov] | |
2120 | ||
2121 | *) Add support for little-endian ppc64 Linux target. | |
2122 | [Marcelo Cerri (IBM)] | |
2123 | ||
2124 | *) Initial support for AMRv8 ISA crypto extensions. This covers AES, | |
2125 | SHA1, SHA256 and GHASH. "Initial" means that most common cases | |
2126 | are optimized and there still is room for further improvements. | |
2127 | Both 32- and 64-bit modes are supported. | |
2128 | [Andy Polyakov, Ard Biesheuvel (Linaro)] | |
2129 | ||
2130 | *) Improved ARMv7 NEON support. | |
2131 | [Andy Polyakov] | |
2132 | ||
2133 | *) Support for SPARC Architecture 2011 crypto extensions, first | |
2134 | implemented in SPARC T4. This covers AES, DES, Camellia, SHA1, | |
2135 | SHA256/512, MD5, GHASH and modular exponentiation. | |
2136 | [Andy Polyakov, David Miller] | |
2137 | ||
2138 | *) Accelerated modular exponentiation for Intel processors, a.k.a. | |
2139 | RSAZ. | |
2140 | [Shay Gueron & Vlad Krasnov (Intel Corp)] | |
2141 | ||
2142 | *) Support for new and upcoming Intel processors, including AVX2, | |
2143 | BMI and SHA ISA extensions. This includes additional "stitched" | |
2144 | implementations, AESNI-SHA256 and GCM, and multi-buffer support | |
2145 | for TLS encrypt. | |
2146 | ||
2147 | This work was sponsored by Intel Corp. | |
2148 | [Andy Polyakov] | |
2149 | ||
2150 | *) Support for DTLS 1.2. This adds two sets of DTLS methods: DTLS_*_method() | |
2151 | supports both DTLS 1.2 and 1.0 and should use whatever version the peer | |
2152 | supports and DTLSv1_2_*_method() which supports DTLS 1.2 only. | |
2153 | [Steve Henson] | |
2154 | ||
2155 | *) Use algorithm specific chains in SSL_CTX_use_certificate_chain_file(): | |
2156 | this fixes a limitation in previous versions of OpenSSL. | |
2157 | [Steve Henson] | |
2158 | ||
2159 | *) Extended RSA OAEP support via EVP_PKEY API. Options to specify digest, | |
2160 | MGF1 digest and OAEP label. | |
2161 | [Steve Henson] | |
2162 | ||
2163 | *) Add EVP support for key wrapping algorithms, to avoid problems with | |
2164 | existing code the flag EVP_CIPHER_CTX_WRAP_ALLOW has to be set in | |
2165 | the EVP_CIPHER_CTX or an error is returned. Add AES and DES3 wrap | |
2166 | algorithms and include tests cases. | |
2167 | [Steve Henson] | |
2168 | ||
2169 | *) Add functions to allocate and set the fields of an ECDSA_METHOD | |
2170 | structure. | |
2171 | [Douglas E. Engert, Steve Henson] | |
2172 | ||
2173 | *) New functions OPENSSL_gmtime_diff and ASN1_TIME_diff to find the | |
2174 | difference in days and seconds between two tm or ASN1_TIME structures. | |
2175 | [Steve Henson] | |
2176 | ||
2177 | *) Add -rev test option to s_server to just reverse order of characters | |
2178 | received by client and send back to server. Also prints an abbreviated | |
2179 | summary of the connection parameters. | |
2180 | [Steve Henson] | |
2181 | ||
2182 | *) New option -brief for s_client and s_server to print out a brief summary | |
2183 | of connection parameters. | |
2184 | [Steve Henson] | |
2185 | ||
2186 | *) Add callbacks for arbitrary TLS extensions. | |
2187 | [Trevor Perrin <trevp@trevp.net> and Ben Laurie] | |
2188 | ||
2189 | *) New option -crl_download in several openssl utilities to download CRLs | |
2190 | from CRLDP extension in certificates. | |
2191 | [Steve Henson] | |
2192 | ||
2193 | *) New options -CRL and -CRLform for s_client and s_server for CRLs. | |
2194 | [Steve Henson] | |
2195 | ||
2196 | *) New function X509_CRL_diff to generate a delta CRL from the difference | |
2197 | of two full CRLs. Add support to "crl" utility. | |
2198 | [Steve Henson] | |
2199 | ||
2200 | *) New functions to set lookup_crls function and to retrieve | |
2201 | X509_STORE from X509_STORE_CTX. | |
2202 | [Steve Henson] | |
2203 | ||
2204 | *) Print out deprecated issuer and subject unique ID fields in | |
2205 | certificates. | |
2206 | [Steve Henson] | |
2207 | ||
2208 | *) Extend OCSP I/O functions so they can be used for simple general purpose | |
2209 | HTTP as well as OCSP. New wrapper function which can be used to download | |
2210 | CRLs using the OCSP API. | |
2211 | [Steve Henson] | |
2212 | ||
2213 | *) Delegate command line handling in s_client/s_server to SSL_CONF APIs. | |
2214 | [Steve Henson] | |
2215 | ||
2216 | *) SSL_CONF* functions. These provide a common framework for application | |
2217 | configuration using configuration files or command lines. | |
2218 | [Steve Henson] | |
2219 | ||
2220 | *) SSL/TLS tracing code. This parses out SSL/TLS records using the | |
2221 | message callback and prints the results. Needs compile time option | |
2222 | "enable-ssl-trace". New options to s_client and s_server to enable | |
2223 | tracing. | |
2224 | [Steve Henson] | |
2225 | ||
2226 | *) New ctrl and macro to retrieve supported points extensions. | |
2227 | Print out extension in s_server and s_client. | |
2228 | [Steve Henson] | |
2229 | ||
2230 | *) New functions to retrieve certificate signature and signature | |
2231 | OID NID. | |
2232 | [Steve Henson] | |
2233 | ||
2234 | *) Add functions to retrieve and manipulate the raw cipherlist sent by a | |
2235 | client to OpenSSL. | |
2236 | [Steve Henson] | |
2237 | ||
2238 | *) New Suite B modes for TLS code. These use and enforce the requirements | |
2239 | of RFC6460: restrict ciphersuites, only permit Suite B algorithms and | |
2240 | only use Suite B curves. The Suite B modes can be set by using the | |
2241 | strings "SUITEB128", "SUITEB192" or "SUITEB128ONLY" for the cipherstring. | |
2242 | [Steve Henson] | |
2243 | ||
2244 | *) New chain verification flags for Suite B levels of security. Check | |
2245 | algorithms are acceptable when flags are set in X509_verify_cert. | |
2246 | [Steve Henson] | |
2247 | ||
2248 | *) Make tls1_check_chain return a set of flags indicating checks passed | |
2249 | by a certificate chain. Add additional tests to handle client | |
2250 | certificates: checks for matching certificate type and issuer name | |
2251 | comparison. | |
2252 | [Steve Henson] | |
2253 | ||
2254 | *) If an attempt is made to use a signature algorithm not in the peer | |
2255 | preference list abort the handshake. If client has no suitable | |
2256 | signature algorithms in response to a certificate request do not | |
2257 | use the certificate. | |
2258 | [Steve Henson] | |
2259 | ||
2260 | *) If server EC tmp key is not in client preference list abort handshake. | |
2261 | [Steve Henson] | |
2262 | ||
2263 | *) Add support for certificate stores in CERT structure. This makes it | |
2264 | possible to have different stores per SSL structure or one store in | |
2265 | the parent SSL_CTX. Include distinct stores for certificate chain | |
2266 | verification and chain building. New ctrl SSL_CTRL_BUILD_CERT_CHAIN | |
2267 | to build and store a certificate chain in CERT structure: returning | |
2268 | an error if the chain cannot be built: this will allow applications | |
2269 | to test if a chain is correctly configured. | |
2270 | ||
2271 | Note: if the CERT based stores are not set then the parent SSL_CTX | |
2272 | store is used to retain compatibility with existing behaviour. | |
2273 | ||
2274 | [Steve Henson] | |
2275 | ||
2276 | *) New function ssl_set_client_disabled to set a ciphersuite disabled | |
2277 | mask based on the current session, check mask when sending client | |
2278 | hello and checking the requested ciphersuite. | |
2279 | [Steve Henson] | |
2280 | ||
2281 | *) New ctrls to retrieve and set certificate types in a certificate | |
2282 | request message. Print out received values in s_client. If certificate | |
2283 | types is not set with custom values set sensible values based on | |
2284 | supported signature algorithms. | |
2285 | [Steve Henson] | |
2286 | ||
2287 | *) Support for distinct client and server supported signature algorithms. | |
2288 | [Steve Henson] | |
2289 | ||
2290 | *) Add certificate callback. If set this is called whenever a certificate | |
2291 | is required by client or server. An application can decide which | |
2292 | certificate chain to present based on arbitrary criteria: for example | |
2293 | supported signature algorithms. Add very simple example to s_server. | |
2294 | This fixes many of the problems and restrictions of the existing client | |
2295 | certificate callback: for example you can now clear an existing | |
2296 | certificate and specify the whole chain. | |
2297 | [Steve Henson] | |
2298 | ||
2299 | *) Add new "valid_flags" field to CERT_PKEY structure which determines what | |
2300 | the certificate can be used for (if anything). Set valid_flags field | |
2301 | in new tls1_check_chain function. Simplify ssl_set_cert_masks which used | |
2302 | to have similar checks in it. | |
2303 | ||
2304 | Add new "cert_flags" field to CERT structure and include a "strict mode". | |
2305 | This enforces some TLS certificate requirements (such as only permitting | |
2306 | certificate signature algorithms contained in the supported algorithms | |
2307 | extension) which some implementations ignore: this option should be used | |
2308 | with caution as it could cause interoperability issues. | |
2309 | [Steve Henson] | |
2310 | ||
2311 | *) Update and tidy signature algorithm extension processing. Work out | |
2312 | shared signature algorithms based on preferences and peer algorithms | |
2313 | and print them out in s_client and s_server. Abort handshake if no | |
2314 | shared signature algorithms. | |
2315 | [Steve Henson] | |
2316 | ||
2317 | *) Add new functions to allow customised supported signature algorithms | |
2318 | for SSL and SSL_CTX structures. Add options to s_client and s_server | |
2319 | to support them. | |
2320 | [Steve Henson] | |
2321 | ||
2322 | *) New function SSL_certs_clear() to delete all references to certificates | |
2323 | from an SSL structure. Before this once a certificate had been added | |
2324 | it couldn't be removed. | |
2325 | [Steve Henson] | |
2326 | ||
2327 | *) Integrate hostname, email address and IP address checking with certificate | |
2328 | verification. New verify options supporting checking in openssl utility. | |
2329 | [Steve Henson] | |
2330 | ||
2331 | *) Fixes and wildcard matching support to hostname and email checking | |
2332 | functions. Add manual page. | |
2333 | [Florian Weimer (Red Hat Product Security Team)] | |
2334 | ||
2335 | *) New functions to check a hostname email or IP address against a | |
2336 | certificate. Add options x509 utility to print results of checks against | |
2337 | a certificate. | |
2338 | [Steve Henson] | |
2339 | ||
2340 | *) Fix OCSP checking. | |
2341 | [Rob Stradling <rob.stradling@comodo.com> and Ben Laurie] | |
2342 | ||
2343 | *) Initial experimental support for explicitly trusted non-root CAs. | |
2344 | OpenSSL still tries to build a complete chain to a root but if an | |
2345 | intermediate CA has a trust setting included that is used. The first | |
2346 | setting is used: whether to trust (e.g., -addtrust option to the x509 | |
2347 | utility) or reject. | |
2348 | [Steve Henson] | |
2349 | ||
2350 | *) Add -trusted_first option which attempts to find certificates in the | |
2351 | trusted store even if an untrusted chain is also supplied. | |
2352 | [Steve Henson] | |
2353 | ||
2354 | *) MIPS assembly pack updates: support for MIPS32r2 and SmartMIPS ASE, | |
2355 | platform support for Linux and Android. | |
2356 | [Andy Polyakov] | |
2357 | ||
2358 | *) Support for linux-x32, ILP32 environment in x86_64 framework. | |
2359 | [Andy Polyakov] | |
2360 | ||
2361 | *) Experimental multi-implementation support for FIPS capable OpenSSL. | |
2362 | When in FIPS mode the approved implementations are used as normal, | |
2363 | when not in FIPS mode the internal unapproved versions are used instead. | |
2364 | This means that the FIPS capable OpenSSL isn't forced to use the | |
2365 | (often lower performance) FIPS implementations outside FIPS mode. | |
2366 | [Steve Henson] | |
2367 | ||
2368 | *) Transparently support X9.42 DH parameters when calling | |
2369 | PEM_read_bio_DHparameters. This means existing applications can handle | |
2370 | the new parameter format automatically. | |
2371 | [Steve Henson] | |
2372 | ||
2373 | *) Initial experimental support for X9.42 DH parameter format: mainly | |
2374 | to support use of 'q' parameter for RFC5114 parameters. | |
2375 | [Steve Henson] | |
2376 | ||
2377 | *) Add DH parameters from RFC5114 including test data to dhtest. | |
2378 | [Steve Henson] | |
2379 | ||
2380 | *) Support for automatic EC temporary key parameter selection. If enabled | |
2381 | the most preferred EC parameters are automatically used instead of | |
2382 | hardcoded fixed parameters. Now a server just has to call: | |
2383 | SSL_CTX_set_ecdh_auto(ctx, 1) and the server will automatically | |
2384 | support ECDH and use the most appropriate parameters. | |
2385 | [Steve Henson] | |
2386 | ||
2387 | *) Enhance and tidy EC curve and point format TLS extension code. Use | |
2388 | static structures instead of allocation if default values are used. | |
2389 | New ctrls to set curves we wish to support and to retrieve shared curves. | |
2390 | Print out shared curves in s_server. New options to s_server and s_client | |
2391 | to set list of supported curves. | |
2392 | [Steve Henson] | |
2393 | ||
2394 | *) New ctrls to retrieve supported signature algorithms and | |
2395 | supported curve values as an array of NIDs. Extend openssl utility | |
2396 | to print out received values. | |
2397 | [Steve Henson] | |
2398 | ||
2399 | *) Add new APIs EC_curve_nist2nid and EC_curve_nid2nist which convert | |
2400 | between NIDs and the more common NIST names such as "P-256". Enhance | |
2401 | ecparam utility and ECC method to recognise the NIST names for curves. | |
2402 | [Steve Henson] | |
2403 | ||
2404 | *) Enhance SSL/TLS certificate chain handling to support different | |
2405 | chains for each certificate instead of one chain in the parent SSL_CTX. | |
2406 | [Steve Henson] | |
2407 | ||
2408 | *) Support for fixed DH ciphersuite client authentication: where both | |
2409 | server and client use DH certificates with common parameters. | |
2410 | [Steve Henson] | |
2411 | ||
2412 | *) Support for fixed DH ciphersuites: those requiring DH server | |
2413 | certificates. | |
2414 | [Steve Henson] | |
2415 | ||
2416 | *) New function i2d_re_X509_tbs for re-encoding the TBS portion of | |
2417 | the certificate. | |
2418 | Note: Related 1.0.2-beta specific macros X509_get_cert_info, | |
2419 | X509_CINF_set_modified, X509_CINF_get_issuer, X509_CINF_get_extensions and | |
2420 | X509_CINF_get_signature were reverted post internal team review. | |
2421 | ||
2422 | Changes between 1.0.1k and 1.0.1l [15 Jan 2015] | |
2423 | ||
2424 | *) Build fixes for the Windows and OpenVMS platforms | |
2425 | [Matt Caswell and Richard Levitte] | |
2426 | ||
2427 | Changes between 1.0.1j and 1.0.1k [8 Jan 2015] | |
2428 | ||
2429 | *) Fix DTLS segmentation fault in dtls1_get_record. A carefully crafted DTLS | |
2430 | message can cause a segmentation fault in OpenSSL due to a NULL pointer | |
2431 | dereference. This could lead to a Denial Of Service attack. Thanks to | |
2432 | Markus Stenberg of Cisco Systems, Inc. for reporting this issue. | |
2433 | (CVE-2014-3571) | |
2434 | [Steve Henson] | |
2435 | ||
2436 | *) Fix DTLS memory leak in dtls1_buffer_record. A memory leak can occur in the | |
2437 | dtls1_buffer_record function under certain conditions. In particular this | |
2438 | could occur if an attacker sent repeated DTLS records with the same | |
2439 | sequence number but for the next epoch. The memory leak could be exploited | |
2440 | by an attacker in a Denial of Service attack through memory exhaustion. | |
2441 | Thanks to Chris Mueller for reporting this issue. | |
2442 | (CVE-2015-0206) | |
2443 | [Matt Caswell] | |
2444 | ||
2445 | *) Fix issue where no-ssl3 configuration sets method to NULL. When openssl is | |
2446 | built with the no-ssl3 option and a SSL v3 ClientHello is received the ssl | |
2447 | method would be set to NULL which could later result in a NULL pointer | |
2448 | dereference. Thanks to Frank Schmirler for reporting this issue. | |
2449 | (CVE-2014-3569) | |
2450 | [Kurt Roeckx] | |
2451 | ||
2452 | *) Abort handshake if server key exchange message is omitted for ephemeral | |
2453 | ECDH ciphersuites. | |
2454 | ||
2455 | Thanks to Karthikeyan Bhargavan of the PROSECCO team at INRIA for | |
2456 | reporting this issue. | |
2457 | (CVE-2014-3572) | |
2458 | [Steve Henson] | |
2459 | ||
2460 | *) Remove non-export ephemeral RSA code on client and server. This code | |
2461 | violated the TLS standard by allowing the use of temporary RSA keys in | |
2462 | non-export ciphersuites and could be used by a server to effectively | |
2463 | downgrade the RSA key length used to a value smaller than the server | |
2464 | certificate. Thanks for Karthikeyan Bhargavan of the PROSECCO team at | |
2465 | INRIA or reporting this issue. | |
2466 | (CVE-2015-0204) | |
2467 | [Steve Henson] | |
2468 | ||
2469 | *) Fixed issue where DH client certificates are accepted without verification. | |
2470 | An OpenSSL server will accept a DH certificate for client authentication | |
2471 | without the certificate verify message. This effectively allows a client to | |
2472 | authenticate without the use of a private key. This only affects servers | |
2473 | which trust a client certificate authority which issues certificates | |
2474 | containing DH keys: these are extremely rare and hardly ever encountered. | |
2475 | Thanks for Karthikeyan Bhargavan of the PROSECCO team at INRIA or reporting | |
2476 | this issue. | |
2477 | (CVE-2015-0205) | |
2478 | [Steve Henson] | |
2479 | ||
2480 | *) Ensure that the session ID context of an SSL is updated when its | |
2481 | SSL_CTX is updated via SSL_set_SSL_CTX. | |
2482 | ||
2483 | The session ID context is typically set from the parent SSL_CTX, | |
2484 | and can vary with the CTX. | |
2485 | [Adam Langley] | |
2486 | ||
2487 | *) Fix various certificate fingerprint issues. | |
2488 | ||
2489 | By using non-DER or invalid encodings outside the signed portion of a | |
2490 | certificate the fingerprint can be changed without breaking the signature. | |
2491 | Although no details of the signed portion of the certificate can be changed | |
2492 | this can cause problems with some applications: e.g. those using the | |
2493 | certificate fingerprint for blacklists. | |
2494 | ||
2495 | 1. Reject signatures with non zero unused bits. | |
2496 | ||
2497 | If the BIT STRING containing the signature has non zero unused bits reject | |
2498 | the signature. All current signature algorithms require zero unused bits. | |
2499 | ||
2500 | 2. Check certificate algorithm consistency. | |
2501 | ||
2502 | Check the AlgorithmIdentifier inside TBS matches the one in the | |
2503 | certificate signature. NB: this will result in signature failure | |
2504 | errors for some broken certificates. | |
2505 | ||
2506 | Thanks to Konrad Kraszewski from Google for reporting this issue. | |
2507 | ||
2508 | 3. Check DSA/ECDSA signatures use DER. | |
2509 | ||
2510 | Re-encode DSA/ECDSA signatures and compare with the original received | |
2511 | signature. Return an error if there is a mismatch. | |
2512 | ||
2513 | This will reject various cases including garbage after signature | |
2514 | (thanks to Antti Karjalainen and Tuomo Untinen from the Codenomicon CROSS | |
2515 | program for discovering this case) and use of BER or invalid ASN.1 INTEGERs | |
2516 | (negative or with leading zeroes). | |
2517 | ||
2518 | Further analysis was conducted and fixes were developed by Stephen Henson | |
2519 | of the OpenSSL core team. | |
2520 | ||
2521 | (CVE-2014-8275) | |
2522 | [Steve Henson] | |
2523 | ||
2524 | *) Correct Bignum squaring. Bignum squaring (BN_sqr) may produce incorrect | |
2525 | results on some platforms, including x86_64. This bug occurs at random | |
2526 | with a very low probability, and is not known to be exploitable in any | |
2527 | way, though its exact impact is difficult to determine. Thanks to Pieter | |
2528 | Wuille (Blockstream) who reported this issue and also suggested an initial | |
2529 | fix. Further analysis was conducted by the OpenSSL development team and | |
2530 | Adam Langley of Google. The final fix was developed by Andy Polyakov of | |
2531 | the OpenSSL core team. | |
2532 | (CVE-2014-3570) | |
2533 | [Andy Polyakov] | |
2534 | ||
2535 | *) Do not resume sessions on the server if the negotiated protocol | |
2536 | version does not match the session's version. Resuming with a different | |
2537 | version, while not strictly forbidden by the RFC, is of questionable | |
2538 | sanity and breaks all known clients. | |
2539 | [David Benjamin, Emilia Käsper] | |
2540 | ||
2541 | *) Tighten handling of the ChangeCipherSpec (CCS) message: reject | |
2542 | early CCS messages during renegotiation. (Note that because | |
2543 | renegotiation is encrypted, this early CCS was not exploitable.) | |
2544 | [Emilia Käsper] | |
2545 | ||
2546 | *) Tighten client-side session ticket handling during renegotiation: | |
2547 | ensure that the client only accepts a session ticket if the server sends | |
2548 | the extension anew in the ServerHello. Previously, a TLS client would | |
2549 | reuse the old extension state and thus accept a session ticket if one was | |
2550 | announced in the initial ServerHello. | |
2551 | ||
2552 | Similarly, ensure that the client requires a session ticket if one | |
2553 | was advertised in the ServerHello. Previously, a TLS client would | |
2554 | ignore a missing NewSessionTicket message. | |
2555 | [Emilia Käsper] | |
2556 | ||
2557 | Changes between 1.0.1i and 1.0.1j [15 Oct 2014] | |
2558 | ||
2559 | *) SRTP Memory Leak. | |
2560 | ||
2561 | A flaw in the DTLS SRTP extension parsing code allows an attacker, who | |
2562 | sends a carefully crafted handshake message, to cause OpenSSL to fail | |
2563 | to free up to 64k of memory causing a memory leak. This could be | |
2564 | exploited in a Denial Of Service attack. This issue affects OpenSSL | |
2565 | 1.0.1 server implementations for both SSL/TLS and DTLS regardless of | |
2566 | whether SRTP is used or configured. Implementations of OpenSSL that | |
2567 | have been compiled with OPENSSL_NO_SRTP defined are not affected. | |

2569 | The fix was developed by the OpenSSL team. | |
2570 | (CVE-2014-3513) | |
2571 | [OpenSSL team] | |
2572 | ||
2573 | *) Session Ticket Memory Leak. | |
2574 | ||
2575 | When an OpenSSL SSL/TLS/DTLS server receives a session ticket the | |
2576 | integrity of that ticket is first verified. In the event of a session | |
2577 | ticket integrity check failing, OpenSSL will fail to free memory | |
2578 | causing a memory leak. By sending a large number of invalid session | |
2579 | tickets an attacker could exploit this issue in a Denial Of Service | |
2580 | attack. | |
2581 | (CVE-2014-3567) | |
2582 | [Steve Henson] | |
2583 | ||
2584 | *) Build option no-ssl3 is incomplete. | |
2585 | ||
2586 | When OpenSSL is configured with "no-ssl3" as a build option, servers | |
2587 | could accept and complete a SSL 3.0 handshake, and clients could be | |
2588 | configured to send them. | |
2589 | (CVE-2014-3568) | |
2590 | [Akamai and the OpenSSL team] | |
2591 | ||
2592 | *) Add support for TLS_FALLBACK_SCSV. | |
2593 | Client applications doing fallback retries should call | |
2594 | SSL_set_mode(s, SSL_MODE_SEND_FALLBACK_SCSV). | |
2595 | (CVE-2014-3566) | |
2596 | [Adam Langley, Bodo Moeller] | |
2597 | ||
2598 | *) Add additional DigestInfo checks. | |
2599 | ||
2600 | Re-encode DigestInto in DER and check against the original when | |
2601 | verifying RSA signature: this will reject any improperly encoded | |
2602 | DigestInfo structures. | |
2603 | ||
2604 | Note: this is a precautionary measure and no attacks are currently known. | |
2605 | ||
2606 | [Steve Henson] | |
2607 | ||
2608 | Changes between 1.0.1h and 1.0.1i [6 Aug 2014] | |
2609 | ||
2610 | *) Fix SRP buffer overrun vulnerability. Invalid parameters passed to the | |
2611 | SRP code can be overrun an internal buffer. Add sanity check that | |
2612 | g, A, B < N to SRP code. | |
2613 | ||
2614 | Thanks to Sean Devlin and Watson Ladd of Cryptography Services, NCC | |
2615 | Group for discovering this issue. | |
2616 | (CVE-2014-3512) | |
2617 | [Steve Henson] | |
2618 | ||
2619 | *) A flaw in the OpenSSL SSL/TLS server code causes the server to negotiate | |
2620 | TLS 1.0 instead of higher protocol versions when the ClientHello message | |
2621 | is badly fragmented. This allows a man-in-the-middle attacker to force a | |
2622 | downgrade to TLS 1.0 even if both the server and the client support a | |
2623 | higher protocol version, by modifying the client's TLS records. | |
2624 | ||
2625 | Thanks to David Benjamin and Adam Langley (Google) for discovering and | |
2626 | researching this issue. | |
2627 | (CVE-2014-3511) | |
2628 | [David Benjamin] | |
2629 | ||
2630 | *) OpenSSL DTLS clients enabling anonymous (EC)DH ciphersuites are subject | |
2631 | to a denial of service attack. A malicious server can crash the client | |
2632 | with a null pointer dereference (read) by specifying an anonymous (EC)DH | |
2633 | ciphersuite and sending carefully crafted handshake messages. | |
2634 | ||
2635 | Thanks to Felix Gröbert (Google) for discovering and researching this | |
2636 | issue. | |
2637 | (CVE-2014-3510) | |
2638 | [Emilia Käsper] | |
2639 | ||
2640 | *) By sending carefully crafted DTLS packets an attacker could cause openssl | |
2641 | to leak memory. This can be exploited through a Denial of Service attack. | |
2642 | Thanks to Adam Langley for discovering and researching this issue. | |
2643 | (CVE-2014-3507) | |
2644 | [Adam Langley] | |
2645 | ||
2646 | *) An attacker can force openssl to consume large amounts of memory whilst | |
2647 | processing DTLS handshake messages. This can be exploited through a | |
2648 | Denial of Service attack. | |
2649 | Thanks to Adam Langley for discovering and researching this issue. | |
2650 | (CVE-2014-3506) | |
2651 | [Adam Langley] | |
2652 | ||
2653 | *) An attacker can force an error condition which causes openssl to crash | |
2654 | whilst processing DTLS packets due to memory being freed twice. This | |
2655 | can be exploited through a Denial of Service attack. | |
2656 | Thanks to Adam Langley and Wan-Teh Chang for discovering and researching | |
2657 | this issue. | |
2658 | (CVE-2014-3505) | |
2659 | [Adam Langley] | |
2660 | ||
2661 | *) If a multithreaded client connects to a malicious server using a resumed | |
2662 | session and the server sends an ec point format extension it could write | |
2663 | up to 255 bytes to freed memory. | |
2664 | ||
2665 | Thanks to Gabor Tyukasz (LogMeIn Inc) for discovering and researching this | |
2666 | issue. | |
2667 | (CVE-2014-3509) | |
2668 | [Gabor Tyukasz] | |
2669 | ||
2670 | *) A malicious server can crash an OpenSSL client with a null pointer | |
2671 | dereference (read) by specifying an SRP ciphersuite even though it was not | |
2672 | properly negotiated with the client. This can be exploited through a | |
2673 | Denial of Service attack. | |
2674 | ||
2675 | Thanks to Joonas Kuorilehto and Riku Hietamäki (Codenomicon) for | |
2676 | discovering and researching this issue. | |
2677 | (CVE-2014-5139) | |
2678 | [Steve Henson] | |
2679 | ||
2680 | *) A flaw in OBJ_obj2txt may cause pretty printing functions such as | |
2681 | X509_name_oneline, X509_name_print_ex et al. to leak some information | |
2682 | from the stack. Applications may be affected if they echo pretty printing | |
2683 | output to the attacker. | |
2684 | ||
2685 | Thanks to Ivan Fratric (Google) for discovering this issue. | |
2686 | (CVE-2014-3508) | |
2687 | [Emilia Käsper, and Steve Henson] | |
2688 | ||
2689 | *) Fix ec_GFp_simple_points_make_affine (thus, EC_POINTs_mul etc.) | |
2690 | for corner cases. (Certain input points at infinity could lead to | |
2691 | bogus results, with non-infinity inputs mapped to infinity too.) | |
2692 | [Bodo Moeller] | |
2693 | ||
2694 | Changes between 1.0.1g and 1.0.1h [5 Jun 2014] | |
2695 | ||
2696 | *) Fix for SSL/TLS MITM flaw. An attacker using a carefully crafted | |
2697 | handshake can force the use of weak keying material in OpenSSL | |
2698 | SSL/TLS clients and servers. | |
2699 | ||
2700 | Thanks to KIKUCHI Masashi (Lepidum Co. Ltd.) for discovering and | |
2701 | researching this issue. (CVE-2014-0224) | |
2702 | [KIKUCHI Masashi, Steve Henson] | |
2703 | ||
2704 | *) Fix DTLS recursion flaw. By sending an invalid DTLS handshake to an | |
2705 | OpenSSL DTLS client the code can be made to recurse eventually crashing | |
2706 | in a DoS attack. | |
2707 | ||
2708 | Thanks to Imre Rad (Search-Lab Ltd.) for discovering this issue. | |
2709 | (CVE-2014-0221) | |
2710 | [Imre Rad, Steve Henson] | |
2711 | ||
2712 | *) Fix DTLS invalid fragment vulnerability. A buffer overrun attack can | |
2713 | be triggered by sending invalid DTLS fragments to an OpenSSL DTLS | |
2714 | client or server. This is potentially exploitable to run arbitrary | |
2715 | code on a vulnerable client or server. | |
2716 | ||
2717 | Thanks to Jüri Aedla for reporting this issue. (CVE-2014-0195) | |
2718 | [Jüri Aedla, Steve Henson] | |
2719 | ||
2720 | *) Fix bug in TLS code where clients enable anonymous ECDH ciphersuites | |
2721 | are subject to a denial of service attack. | |
2722 | ||
2723 | Thanks to Felix Gröbert and Ivan Fratric at Google for discovering | |
2724 | this issue. (CVE-2014-3470) | |
2725 | [Felix Gröbert, Ivan Fratric, Steve Henson] | |
2726 | ||
2727 | *) Harmonize version and its documentation. -f flag is used to display | |
2728 | compilation flags. | |
2729 | [mancha <mancha1@zoho.com>] | |
2730 | ||
2731 | *) Fix eckey_priv_encode so it immediately returns an error upon a failure | |
2732 | in i2d_ECPrivateKey. | |
2733 | [mancha <mancha1@zoho.com>] | |
2734 | ||
2735 | *) Fix some double frees. These are not thought to be exploitable. | |
2736 | [mancha <mancha1@zoho.com>] | |
2737 | ||
2738 | Changes between 1.0.1f and 1.0.1g [7 Apr 2014] | |
2739 | ||
2740 | *) A missing bounds check in the handling of the TLS heartbeat extension | |
2741 | can be used to reveal up to 64k of memory to a connected client or | |
2742 | server. | |
2743 | ||
2744 | Thanks for Neel Mehta of Google Security for discovering this bug and to | |
2745 | Adam Langley <agl@chromium.org> and Bodo Moeller <bmoeller@acm.org> for | |
2746 | preparing the fix (CVE-2014-0160) | |
2747 | [Adam Langley, Bodo Moeller] | |
2748 | ||
2749 | *) Fix for the attack described in the paper "Recovering OpenSSL | |
2750 | ECDSA Nonces Using the FLUSH+RELOAD Cache Side-channel Attack" | |
2751 | by Yuval Yarom and Naomi Benger. Details can be obtained from: | |
2752 | http://eprint.iacr.org/2014/140 | |
2753 | ||
2754 | Thanks to Yuval Yarom and Naomi Benger for discovering this | |
2755 | flaw and to Yuval Yarom for supplying a fix (CVE-2014-0076) | |
2756 | [Yuval Yarom and Naomi Benger] | |
2757 | ||
2758 | *) TLS pad extension: draft-agl-tls-padding-03 | |
2759 | ||
2760 | Workaround for the "TLS hang bug" (see FAQ and PR#2771): if the | |
2761 | TLS client Hello record length value would otherwise be > 255 and | |
2762 | less that 512 pad with a dummy extension containing zeroes so it | |
2763 | is at least 512 bytes long. | |
2764 | ||
2765 | [Adam Langley, Steve Henson] | |
2766 | ||
2767 | Changes between 1.0.1e and 1.0.1f [6 Jan 2014] | |
2768 | ||
2769 | *) Fix for TLS record tampering bug. A carefully crafted invalid | |
2770 | handshake could crash OpenSSL with a NULL pointer exception. | |
2771 | Thanks to Anton Johansson for reporting this issues. | |
2772 | (CVE-2013-4353) | |
2773 | ||
2774 | *) Keep original DTLS digest and encryption contexts in retransmission | |
2775 | structures so we can use the previous session parameters if they need | |
2776 | to be resent. (CVE-2013-6450) | |
2777 | [Steve Henson] | |
2778 | ||
2779 | *) Add option SSL_OP_SAFARI_ECDHE_ECDSA_BUG (part of SSL_OP_ALL) which | |
2780 | avoids preferring ECDHE-ECDSA ciphers when the client appears to be | |
2781 | Safari on OS X. Safari on OS X 10.8..10.8.3 advertises support for | |
2782 | several ECDHE-ECDSA ciphers, but fails to negotiate them. The bug | |
2783 | is fixed in OS X 10.8.4, but Apple have ruled out both hot fixing | |
2784 | 10.8..10.8.3 and forcing users to upgrade to 10.8.4 or newer. | |
2785 | [Rob Stradling, Adam Langley] | |
2786 | ||
2787 | Changes between 1.0.1d and 1.0.1e [11 Feb 2013] | |
2788 | ||
2789 | *) Correct fix for CVE-2013-0169. The original didn't work on AES-NI | |
2790 | supporting platforms or when small records were transferred. | |
2791 | [Andy Polyakov, Steve Henson] | |
2792 | ||
2793 | Changes between 1.0.1c and 1.0.1d [5 Feb 2013] | |
2794 | ||
2795 | *) Make the decoding of SSLv3, TLS and DTLS CBC records constant time. | |
2796 | ||
2797 | This addresses the flaw in CBC record processing discovered by | |
2798 | Nadhem Alfardan and Kenny Paterson. Details of this attack can be found | |
2799 | at: http://www.isg.rhul.ac.uk/tls/ | |
2800 | ||
2801 | Thanks go to Nadhem Alfardan and Kenny Paterson of the Information | |
2802 | Security Group at Royal Holloway, University of London | |
2803 | (www.isg.rhul.ac.uk) for discovering this flaw and Adam Langley and | |
2804 | Emilia Käsper for the initial patch. | |

2806 | [Emilia Käsper, Adam Langley, Ben Laurie, Andy Polyakov, Steve Henson] | |
2807 | ||
2808 | *) Fix flaw in AESNI handling of TLS 1.2 and 1.1 records for CBC mode | |
2809 | ciphersuites which can be exploited in a denial of service attack. | |
2810 | Thanks go to and to Adam Langley <agl@chromium.org> for discovering | |
2811 | and detecting this bug and to Wolfgang Ettlinger | |
2812 | <wolfgang.ettlinger@gmail.com> for independently discovering this issue. | |
2813 | (CVE-2012-2686) | |
2814 | [Adam Langley] | |
2815 | ||
2816 | *) Return an error when checking OCSP signatures when key is NULL. | |
2817 | This fixes a DoS attack. (CVE-2013-0166) | |
2818 | [Steve Henson] | |
2819 | ||
2820 | *) Make openssl verify return errors. | |
2821 | [Chris Palmer <palmer@google.com> and Ben Laurie] | |
2822 | ||
2823 | *) Call OCSP Stapling callback after ciphersuite has been chosen, so | |
2824 | the right response is stapled. Also change SSL_get_certificate() | |
2825 | so it returns the certificate actually sent. | |
2826 | See http://rt.openssl.org/Ticket/Display.html?id=2836. | |
2827 | [Rob Stradling <rob.stradling@comodo.com>] | |
2828 | ||
2829 | *) Fix possible deadlock when decoding public keys. | |
2830 | [Steve Henson] | |
2831 | ||
2832 | *) Don't use TLS 1.0 record version number in initial client hello | |
2833 | if renegotiating. | |
2834 | [Steve Henson] | |
2835 | ||
2836 | Changes between 1.0.1b and 1.0.1c [10 May 2012] | |
2837 | ||
2838 | *) Sanity check record length before skipping explicit IV in TLS | |
2839 | 1.2, 1.1 and DTLS to fix DoS attack. | |
2840 | ||
2841 | Thanks to Codenomicon for discovering this issue using Fuzz-o-Matic | |
2842 | fuzzing as a service testing platform. | |
2843 | (CVE-2012-2333) | |
2844 | [Steve Henson] | |
2845 | ||
2846 | *) Initialise tkeylen properly when encrypting CMS messages. | |
2847 | Thanks to Solar Designer of Openwall for reporting this issue. | |
2848 | [Steve Henson] | |
2849 | ||
2850 | *) In FIPS mode don't try to use composite ciphers as they are not | |
2851 | approved. | |
2852 | [Steve Henson] | |
2853 | ||
2854 | Changes between 1.0.1a and 1.0.1b [26 Apr 2012] | |
2855 | ||
2856 | *) OpenSSL 1.0.0 sets SSL_OP_ALL to 0x80000FFFL and OpenSSL 1.0.1 and | |
2857 | 1.0.1a set SSL_OP_NO_TLSv1_1 to 0x00000400L which would unfortunately | |
2858 | mean any application compiled against OpenSSL 1.0.0 headers setting | |
2859 | SSL_OP_ALL would also set SSL_OP_NO_TLSv1_1, unintentionally disabling | |
2860 | TLS 1.1 also. Fix this by changing the value of SSL_OP_NO_TLSv1_1 to | |
2861 | 0x10000000L Any application which was previously compiled against | |
2862 | OpenSSL 1.0.1 or 1.0.1a headers and which cares about SSL_OP_NO_TLSv1_1 | |
2863 | will need to be recompiled as a result. Letting be results in | |
2864 | inability to disable specifically TLS 1.1 and in client context, | |
2865 | in unlike event, limit maximum offered version to TLS 1.0 [see below]. | |
2866 | [Steve Henson] | |
2867 | ||
2868 | *) In order to ensure interoperability SSL_OP_NO_protocolX does not | |
2869 | disable just protocol X, but all protocols above X *if* there are | |
2870 | protocols *below* X still enabled. In more practical terms it means | |
2871 | that if application wants to disable TLS1.0 in favor of TLS1.1 and | |
2872 | above, it's not sufficient to pass SSL_OP_NO_TLSv1, one has to pass | |
2873 | SSL_OP_NO_TLSv1|SSL_OP_NO_SSLv3|SSL_OP_NO_SSLv2. This applies to | |
2874 | client side. | |
2875 | [Andy Polyakov] | |
2876 | ||
2877 | Changes between 1.0.1 and 1.0.1a [19 Apr 2012] | |
2878 | ||
2879 | *) Check for potentially exploitable overflows in asn1_d2i_read_bio | |
2880 | BUF_mem_grow and BUF_mem_grow_clean. Refuse attempts to shrink buffer | |
2881 | in CRYPTO_realloc_clean. | |
2882 | ||
2883 | Thanks to Tavis Ormandy, Google Security Team, for discovering this | |
2884 | issue and to Adam Langley <agl@chromium.org> for fixing it. | |
2885 | (CVE-2012-2110) | |
2886 | [Adam Langley (Google), Tavis Ormandy, Google Security Team] | |
2887 | ||
2888 | *) Don't allow TLS 1.2 SHA-256 ciphersuites in TLS 1.0, 1.1 connections. | |
2889 | [Adam Langley] | |
2890 | ||
2891 | *) Workarounds for some broken servers that "hang" if a client hello | |
2892 | record length exceeds 255 bytes. | |
2893 | ||
2894 | 1. Do not use record version number > TLS 1.0 in initial client | |
2895 | hello: some (but not all) hanging servers will now work. | |
2896 | 2. If we set OPENSSL_MAX_TLS1_2_CIPHER_LENGTH this will truncate | |
2897 | the number of ciphers sent in the client hello. This should be | |
2898 | set to an even number, such as 50, for example by passing: | |
2899 | -DOPENSSL_MAX_TLS1_2_CIPHER_LENGTH=50 to config or Configure. | |
2900 | Most broken servers should now work. | |
2901 | 3. If all else fails setting OPENSSL_NO_TLS1_2_CLIENT will disable | |
2902 | TLS 1.2 client support entirely. | |
2903 | [Steve Henson] | |
2904 | ||
2905 | *) Fix SEGV in Vector Permutation AES module observed in OpenSSH. | |
2906 | [Andy Polyakov] | |
2907 | ||
2908 | Changes between 1.0.0h and 1.0.1 [14 Mar 2012] | |
2909 | ||
2910 | *) Add compatibility with old MDC2 signatures which use an ASN1 OCTET | |
2911 | STRING form instead of a DigestInfo. | |
2912 | [Steve Henson] | |
2913 | ||
2914 | *) The format used for MDC2 RSA signatures is inconsistent between EVP | |
2915 | and the RSA_sign/RSA_verify functions. This was made more apparent when | |
2916 | OpenSSL used RSA_sign/RSA_verify for some RSA signatures in particular | |
2917 | those which went through EVP_PKEY_METHOD in 1.0.0 and later. Detect | |
2918 | the correct format in RSA_verify so both forms transparently work. | |
2919 | [Steve Henson] | |
2920 | ||
2921 | *) Some servers which support TLS 1.0 can choke if we initially indicate | |
2922 | support for TLS 1.2 and later renegotiate using TLS 1.0 in the RSA | |
2923 | encrypted premaster secret. As a workaround use the maximum permitted | |
2924 | client version in client hello, this should keep such servers happy | |
2925 | and still work with previous versions of OpenSSL. | |
2926 | [Steve Henson] | |
2927 | ||
2928 | *) Add support for TLS/DTLS heartbeats. | |
2929 | [Robin Seggelmann <seggelmann@fh-muenster.de>] | |
2930 | ||
2931 | *) Add support for SCTP. | |
2932 | [Robin Seggelmann <seggelmann@fh-muenster.de>] | |
2933 | ||
2934 | *) Improved PRNG seeding for VOS. | |
2935 | [Paul Green <Paul.Green@stratus.com>] | |
2936 | ||
2937 | *) Extensive assembler packs updates, most notably: | |
2938 | ||
2939 | - x86[_64]: AES-NI, PCLMULQDQ, RDRAND support; | |
2940 | - x86[_64]: SSSE3 support (SHA1, vector-permutation AES); | |
2941 | - x86_64: bit-sliced AES implementation; | |
2942 | - ARM: NEON support, contemporary platforms optimizations; | |
2943 | - s390x: z196 support; | |
2944 | - *: GHASH and GF(2^m) multiplication implementations; | |
2945 | ||
2946 | [Andy Polyakov] | |
2947 | ||
2948 | *) Make TLS-SRP code conformant with RFC 5054 API cleanup | |
2949 | (removal of unnecessary code) | |
2950 | [Peter Sylvester <peter.sylvester@edelweb.fr>] | |
2951 | ||
2952 | *) Add TLS key material exporter from RFC 5705. | |
2953 | [Eric Rescorla] | |
2954 | ||
2955 | *) Add DTLS-SRTP negotiation from RFC 5764. | |
2956 | [Eric Rescorla] | |
2957 | ||
2958 | *) Add Next Protocol Negotiation, | |
2959 | http://tools.ietf.org/html/draft-agl-tls-nextprotoneg-00. Can be | |
2960 | disabled with a no-npn flag to config or Configure. Code donated | |
2961 | by Google. | |
2962 | [Adam Langley <agl@google.com> and Ben Laurie] | |
2963 | ||
2964 | *) Add optional 64-bit optimized implementations of elliptic curves NIST-P224, | |
2965 | NIST-P256, NIST-P521, with constant-time single point multiplication on | |
2966 | typical inputs. Compiler support for the nonstandard type __uint128_t is | |
2967 | required to use this (present in gcc 4.4 and later, for 64-bit builds). | |
2968 | Code made available under Apache License version 2.0. | |
2969 | ||
2970 | Specify "enable-ec_nistp_64_gcc_128" on the Configure (or config) command | |
2971 | line to include this in your build of OpenSSL, and run "make depend" (or | |
2972 | "make update"). This enables the following EC_METHODs: | |
2973 | ||
2974 | EC_GFp_nistp224_method() | |
2975 | EC_GFp_nistp256_method() | |
2976 | EC_GFp_nistp521_method() | |
2977 | ||
2978 | EC_GROUP_new_by_curve_name() will automatically use these (while | |
2979 | EC_GROUP_new_curve_GFp() currently prefers the more flexible | |
2980 | implementations). | |
2981 | [Emilia Käsper, Adam Langley, Bodo Moeller (Google)] | |
2982 | ||
2983 | *) Use type ossl_ssize_t instad of ssize_t which isn't available on | |
2984 | all platforms. Move ssize_t definition from e_os.h to the public | |
2985 | header file e_os2.h as it now appears in public header file cms.h | |
2986 | [Steve Henson] | |
2987 | ||
2988 | *) New -sigopt option to the ca, req and x509 utilities. Additional | |
2989 | signature parameters can be passed using this option and in | |
2990 | particular PSS. | |
2991 | [Steve Henson] | |
2992 | ||
2993 | *) Add RSA PSS signing function. This will generate and set the | |
2994 | appropriate AlgorithmIdentifiers for PSS based on those in the | |
2995 | corresponding EVP_MD_CTX structure. No application support yet. | |
2996 | [Steve Henson] | |
2997 | ||
2998 | *) Support for companion algorithm specific ASN1 signing routines. | |
2999 | New function ASN1_item_sign_ctx() signs a pre-initialised | |
3000 | EVP_MD_CTX structure and sets AlgorithmIdentifiers based on | |
3001 | the appropriate parameters. | |
3002 | [Steve Henson] | |
3003 | ||
3004 | *) Add new algorithm specific ASN1 verification initialisation function | |
3005 | to EVP_PKEY_ASN1_METHOD: this is not in EVP_PKEY_METHOD since the ASN1 | |
3006 | handling will be the same no matter what EVP_PKEY_METHOD is used. | |
3007 | Add a PSS handler to support verification of PSS signatures: checked | |
3008 | against a number of sample certificates. | |
3009 | [Steve Henson] | |
3010 | ||
3011 | *) Add signature printing for PSS. Add PSS OIDs. | |
3012 | [Steve Henson, Martin Kaiser <lists@kaiser.cx>] | |
3013 | ||
3014 | *) Add algorithm specific signature printing. An individual ASN1 method | |
3015 | can now print out signatures instead of the standard hex dump. | |
3016 | ||
3017 | More complex signatures (e.g. PSS) can print out more meaningful | |
3018 | information. Include DSA version that prints out the signature | |
3019 | parameters r, s. | |
3020 | [Steve Henson] | |
3021 | ||
3022 | *) Password based recipient info support for CMS library: implementing | |
3023 | RFC3211. | |
3024 | [Steve Henson] | |
3025 | ||
3026 | *) Split password based encryption into PBES2 and PBKDF2 functions. This | |
3027 | neatly separates the code into cipher and PBE sections and is required | |
3028 | for some algorithms that split PBES2 into separate pieces (such as | |
3029 | password based CMS). | |
3030 | [Steve Henson] | |
3031 | ||
3032 | *) Session-handling fixes: | |
3033 | - Fix handling of connections that are resuming with a session ID, | |
3034 | but also support Session Tickets. | |
3035 | - Fix a bug that suppressed issuing of a new ticket if the client | |
3036 | presented a ticket with an expired session. | |
3037 | - Try to set the ticket lifetime hint to something reasonable. | |
3038 | - Make tickets shorter by excluding irrelevant information. | |
3039 | - On the client side, don't ignore renewed tickets. | |
3040 | [Adam Langley, Bodo Moeller (Google)] | |
3041 | ||
3042 | *) Fix PSK session representation. | |
3043 | [Bodo Moeller] | |
3044 | ||
3045 | *) Add RC4-MD5 and AESNI-SHA1 "stitched" implementations. | |
3046 | ||
3047 | This work was sponsored by Intel. | |
3048 | [Andy Polyakov] | |
3049 | ||
3050 | *) Add GCM support to TLS library. Some custom code is needed to split | |
3051 | the IV between the fixed (from PRF) and explicit (from TLS record) | |
3052 | portions. This adds all GCM ciphersuites supported by RFC5288 and | |
3053 | RFC5289. Generalise some AES* cipherstrings to include GCM and | |
3054 | add a special AESGCM string for GCM only. | |
3055 | [Steve Henson] | |
3056 | ||
3057 | *) Expand range of ctrls for AES GCM. Permit setting invocation | |
3058 | field on decrypt and retrieval of invocation field only on encrypt. | |
3059 | [Steve Henson] | |
3060 | ||
3061 | *) Add HMAC ECC ciphersuites from RFC5289. Include SHA384 PRF support. | |
3062 | As required by RFC5289 these ciphersuites cannot be used if for | |
3063 | versions of TLS earlier than 1.2. | |
3064 | [Steve Henson] | |
3065 | ||
3066 | *) For FIPS capable OpenSSL interpret a NULL default public key method | |
3067 | as unset and return the appropriate default but do *not* set the default. | |
3068 | This means we can return the appropriate method in applications that | |
3069 | switch between FIPS and non-FIPS modes. | |
3070 | [Steve Henson] | |
3071 | ||
3072 | *) Redirect HMAC and CMAC operations to FIPS module in FIPS mode. If an | |
3073 | ENGINE is used then we cannot handle that in the FIPS module so we | |
3074 | keep original code iff non-FIPS operations are allowed. | |
3075 | [Steve Henson] | |
3076 | ||
3077 | *) Add -attime option to openssl utilities. | |
3078 | [Peter Eckersley <pde@eff.org>, Ben Laurie and Steve Henson] | |
3079 | ||
3080 | *) Redirect DSA and DH operations to FIPS module in FIPS mode. | |
3081 | [Steve Henson] | |
3082 | ||
3083 | *) Redirect ECDSA and ECDH operations to FIPS module in FIPS mode. Also use | |
3084 | FIPS EC methods unconditionally for now. | |
3085 | [Steve Henson] | |
3086 | ||
3087 | *) New build option no-ec2m to disable characteristic 2 code. | |
3088 | [Steve Henson] | |
3089 | ||
3090 | *) Backport libcrypto audit of return value checking from 1.1.0-dev; not | |
3091 | all cases can be covered as some introduce binary incompatibilities. | |
3092 | [Steve Henson] | |
3093 | ||
3094 | *) Redirect RSA operations to FIPS module including keygen, | |
3095 | encrypt, decrypt, sign and verify. Block use of non FIPS RSA methods. | |
3096 | [Steve Henson] | |
3097 | ||
3098 | *) Add similar low level API blocking to ciphers. | |
3099 | [Steve Henson] | |
3100 | ||
3101 | *) Low level digest APIs are not approved in FIPS mode: any attempt | |
3102 | to use these will cause a fatal error. Applications that *really* want | |
3103 | to use them can use the private_* version instead. | |
3104 | [Steve Henson] | |
3105 | ||
3106 | *) Redirect cipher operations to FIPS module for FIPS builds. | |
3107 | [Steve Henson] | |
3108 | ||
3109 | *) Redirect digest operations to FIPS module for FIPS builds. | |
3110 | [Steve Henson] | |
3111 | ||
3112 | *) Update build system to add "fips" flag which will link in fipscanister.o | |
3113 | for static and shared library builds embedding a signature if needed. | |
3114 | [Steve Henson] | |
3115 | ||
3116 | *) Output TLS supported curves in preference order instead of numerical | |
3117 | order. This is currently hardcoded for the highest order curves first. | |
3118 | This should be configurable so applications can judge speed vs strength. | |
3119 | [Steve Henson] | |
3120 | ||
3121 | *) Add TLS v1.2 server support for client authentication. | |
3122 | [Steve Henson] | |
3123 | ||
3124 | *) Add support for FIPS mode in ssl library: disable SSLv3, non-FIPS ciphers | |
3125 | and enable MD5. | |
3126 | [Steve Henson] | |
3127 | ||
3128 | *) Functions FIPS_mode_set() and FIPS_mode() which call the underlying | |
3129 | FIPS modules versions. | |
3130 | [Steve Henson] | |
3131 | ||
3132 | *) Add TLS v1.2 client side support for client authentication. Keep cache | |
3133 | of handshake records longer as we don't know the hash algorithm to use | |
3134 | until after the certificate request message is received. | |
3135 | [Steve Henson] | |
3136 | ||
3137 | *) Initial TLS v1.2 client support. Add a default signature algorithms | |
3138 | extension including all the algorithms we support. Parse new signature | |
3139 | format in client key exchange. Relax some ECC signing restrictions for | |
3140 | TLS v1.2 as indicated in RFC5246. | |
3141 | [Steve Henson] | |
3142 | ||
3143 | *) Add server support for TLS v1.2 signature algorithms extension. Switch | |
3144 | to new signature format when needed using client digest preference. | |
3145 | All server ciphersuites should now work correctly in TLS v1.2. No client | |
3146 | support yet and no support for client certificates. | |
3147 | [Steve Henson] | |
3148 | ||
3149 | *) Initial TLS v1.2 support. Add new SHA256 digest to ssl code, switch | |
3150 | to SHA256 for PRF when using TLS v1.2 and later. Add new SHA256 based | |
3151 | ciphersuites. At present only RSA key exchange ciphersuites work with | |
3152 | TLS v1.2. Add new option for TLS v1.2 replacing the old and obsolete | |
3153 | SSL_OP_PKCS1_CHECK flags with SSL_OP_NO_TLSv1_2. New TLSv1.2 methods | |
3154 | and version checking. | |
3155 | [Steve Henson] | |
3156 | ||
3157 | *) New option OPENSSL_NO_SSL_INTERN. If an application can be compiled | |
3158 | with this defined it will not be affected by any changes to ssl internal | |
3159 | structures. Add several utility functions to allow openssl application | |
3160 | to work with OPENSSL_NO_SSL_INTERN defined. | |
3161 | [Steve Henson] | |
3162 | ||
3163 | *) Add SRP support. | |
3164 | [Tom Wu <tjw@cs.stanford.edu> and Ben Laurie] | |
3165 | ||
3166 | *) Add functions to copy EVP_PKEY_METHOD and retrieve flags and id. | |
3167 | [Steve Henson] | |
3168 | ||
3169 | *) Permit abbreviated handshakes when renegotiating using the function | |
3170 | SSL_renegotiate_abbreviated(). | |
3171 | [Robin Seggelmann <seggelmann@fh-muenster.de>] | |
3172 | ||
3173 | *) Add call to ENGINE_register_all_complete() to | |
3174 | ENGINE_load_builtin_engines(), so some implementations get used | |
3175 | automatically instead of needing explicit application support. | |
3176 | [Steve Henson] | |
3177 | ||
3178 | *) Add support for TLS key exporter as described in RFC5705. | |
3179 | [Robin Seggelmann <seggelmann@fh-muenster.de>, Steve Henson] | |
3180 | ||
3181 | *) Initial TLSv1.1 support. Since TLSv1.1 is very similar to TLS v1.0 only | |
3182 | a few changes are required: | |
3183 | ||
3184 | Add SSL_OP_NO_TLSv1_1 flag. | |
3185 | Add TLSv1_1 methods. | |
3186 | Update version checking logic to handle version 1.1. | |
3187 | Add explicit IV handling (ported from DTLS code). | |
3188 | Add command line options to s_client/s_server. | |
3189 | [Steve Henson] | |
3190 | ||
3191 | Changes between 1.0.0g and 1.0.0h [12 Mar 2012] | |
3192 | ||
3193 | *) Fix MMA (Bleichenbacher's attack on PKCS #1 v1.5 RSA padding) weakness | |
3194 | in CMS and PKCS7 code. When RSA decryption fails use a random key for | |
3195 | content decryption and always return the same error. Note: this attack | |
3196 | needs on average 2^20 messages so it only affects automated senders. The | |
3197 | old behaviour can be re-enabled in the CMS code by setting the | |
3198 | CMS_DEBUG_DECRYPT flag: this is useful for debugging and testing where | |
3199 | an MMA defence is not necessary. | |
3200 | Thanks to Ivan Nestlerode <inestlerode@us.ibm.com> for discovering | |
3201 | this issue. (CVE-2012-0884) | |
3202 | [Steve Henson] | |
3203 | ||
3204 | *) Fix CVE-2011-4619: make sure we really are receiving a | |
3205 | client hello before rejecting multiple SGC restarts. Thanks to | |
3206 | Ivan Nestlerode <inestlerode@us.ibm.com> for discovering this bug. | |
3207 | [Steve Henson] | |
3208 | ||
3209 | Changes between 1.0.0f and 1.0.0g [18 Jan 2012] | |
3210 | ||
3211 | *) Fix for DTLS DoS issue introduced by fix for CVE-2011-4109. | |
3212 | Thanks to Antonio Martin, Enterprise Secure Access Research and | |
3213 | Development, Cisco Systems, Inc. for discovering this bug and | |
3214 | preparing a fix. (CVE-2012-0050) | |
3215 | [Antonio Martin] | |
3216 | ||
3217 | Changes between 1.0.0e and 1.0.0f [4 Jan 2012] | |
3218 | ||
3219 | *) Nadhem Alfardan and Kenny Paterson have discovered an extension | |
3220 | of the Vaudenay padding oracle attack on CBC mode encryption | |
3221 | which enables an efficient plaintext recovery attack against | |
3222 | the OpenSSL implementation of DTLS. Their attack exploits timing | |
3223 | differences arising during decryption processing. A research | |
3224 | paper describing this attack can be found at: | |
3225 | http://www.isg.rhul.ac.uk/~kp/dtls.pdf | |
3226 | Thanks go to Nadhem Alfardan and Kenny Paterson of the Information | |
3227 | Security Group at Royal Holloway, University of London | |
3228 | (www.isg.rhul.ac.uk) for discovering this flaw and to Robin Seggelmann | |
3229 | <seggelmann@fh-muenster.de> and Michael Tuexen <tuexen@fh-muenster.de> | |
3230 | for preparing the fix. (CVE-2011-4108) | |
3231 | [Robin Seggelmann, Michael Tuexen] | |
3232 | ||
3233 | *) Clear bytes used for block padding of SSL 3.0 records. | |
3234 | (CVE-2011-4576) | |
3235 | [Adam Langley (Google)] | |
3236 | ||
3237 | *) Only allow one SGC handshake restart for SSL/TLS. Thanks to George | |
3238 | Kadianakis <desnacked@gmail.com> for discovering this issue and | |
3239 | Adam Langley for preparing the fix. (CVE-2011-4619) | |
3240 | [Adam Langley (Google)] | |
3241 | ||
3242 | *) Check parameters are not NULL in GOST ENGINE. (CVE-2012-0027) | |
3243 | [Andrey Kulikov <amdeich@gmail.com>] | |
3244 | ||
3245 | *) Prevent malformed RFC3779 data triggering an assertion failure. | |
3246 | Thanks to Andrew Chi, BBN Technologies, for discovering the flaw | |
3247 | and Rob Austein <sra@hactrn.net> for fixing it. (CVE-2011-4577) | |
3248 | [Rob Austein <sra@hactrn.net>] | |
3249 | ||
3250 | *) Improved PRNG seeding for VOS. | |
3251 | [Paul Green <Paul.Green@stratus.com>] | |
3252 | ||
3253 | *) Fix ssl_ciph.c set-up race. | |
3254 | [Adam Langley (Google)] | |
3255 | ||
3256 | *) Fix spurious failures in ecdsatest.c. | |
3257 | [Emilia Käsper (Google)] | |
3258 | ||
3259 | *) Fix the BIO_f_buffer() implementation (which was mixing different | |
3260 | interpretations of the '..._len' fields). | |
3261 | [Adam Langley (Google)] | |
3262 | ||
3263 | *) Fix handling of BN_BLINDING: now BN_BLINDING_invert_ex (rather than | |
3264 | BN_BLINDING_invert_ex) calls BN_BLINDING_update, ensuring that concurrent | |
3265 | threads won't reuse the same blinding coefficients. | |
3266 | ||
3267 | This also avoids the need to obtain the CRYPTO_LOCK_RSA_BLINDING | |
3268 | lock to call BN_BLINDING_invert_ex, and avoids one use of | |
3269 | BN_BLINDING_update for each BN_BLINDING structure (previously, | |
3270 | the last update always remained unused). | |
3271 | [Emilia Käsper (Google)] | |
3272 | ||
3273 | *) In ssl3_clear, preserve s3->init_extra along with s3->rbuf. | |
3274 | [Bob Buckholz (Google)] | |
3275 | ||
3276 | Changes between 1.0.0d and 1.0.0e [6 Sep 2011] | |
3277 | ||
3278 | *) Fix bug where CRLs with nextUpdate in the past are sometimes accepted | |
3279 | by initialising X509_STORE_CTX properly. (CVE-2011-3207) | |
3280 | [Kaspar Brand <ossl@velox.ch>] | |
3281 | ||
3282 | *) Fix SSL memory handling for (EC)DH ciphersuites, in particular | |
3283 | for multi-threaded use of ECDH. (CVE-2011-3210) | |
3284 | [Adam Langley (Google)] | |
3285 | ||
3286 | *) Fix x509_name_ex_d2i memory leak on bad inputs. | |
3287 | [Bodo Moeller] | |
3288 | ||
3289 | *) Remove hard coded ecdsaWithSHA1 signature tests in ssl code and check | |
3290 | signature public key algorithm by using OID xref utilities instead. | |
3291 | Before this you could only use some ECC ciphersuites with SHA1 only. | |
3292 | [Steve Henson] | |
3293 | ||
3294 | *) Add protection against ECDSA timing attacks as mentioned in the paper | |
3295 | by Billy Bob Brumley and Nicola Tuveri, see: | |
3296 | ||
3297 | http://eprint.iacr.org/2011/232.pdf | |
3298 | ||
3299 | [Billy Bob Brumley and Nicola Tuveri] | |
3300 | ||
3301 | Changes between 1.0.0c and 1.0.0d [8 Feb 2011] | |
3302 | ||
3303 | *) Fix parsing of OCSP stapling ClientHello extension. CVE-2011-0014 | |
3304 | [Neel Mehta, Adam Langley, Bodo Moeller (Google)] | |
3305 | ||
3306 | *) Fix bug in string printing code: if *any* escaping is enabled we must | |
3307 | escape the escape character (backslash) or the resulting string is | |
3308 | ambiguous. | |
3309 | [Steve Henson] | |
3310 | ||
3311 | Changes between 1.0.0b and 1.0.0c [2 Dec 2010] | |
3312 | ||
3313 | *) Disable code workaround for ancient and obsolete Netscape browsers | |
3314 | and servers: an attacker can use it in a ciphersuite downgrade attack. | |
3315 | Thanks to Martin Rex for discovering this bug. CVE-2010-4180 | |
3316 | [Steve Henson] | |
3317 | ||
3318 | *) Fixed J-PAKE implementation error, originally discovered by | |
3319 | Sebastien Martini, further info and confirmation from Stefan | |
3320 | Arentz and Feng Hao. Note that this fix is a security fix. CVE-2010-4252 | |
3321 | [Ben Laurie] | |
3322 | ||
3323 | Changes between 1.0.0a and 1.0.0b [16 Nov 2010] | |
3324 | ||
3325 | *) Fix extension code to avoid race conditions which can result in a buffer | |
3326 | overrun vulnerability: resumed sessions must not be modified as they can | |
3327 | be shared by multiple threads. CVE-2010-3864 | |
3328 | [Steve Henson] | |
3329 | ||
3330 | *) Fix WIN32 build system to correctly link an ENGINE directory into | |
3331 | a DLL. | |
3332 | [Steve Henson] | |
3333 | ||
3334 | Changes between 1.0.0 and 1.0.0a [01 Jun 2010] | |
3335 | ||
3336 | *) Check return value of int_rsa_verify in pkey_rsa_verifyrecover | |
3337 | (CVE-2010-1633) | |
3338 | [Steve Henson, Peter-Michael Hager <hager@dortmund.net>] | |
3339 | ||
3340 | Changes between 0.9.8n and 1.0.0 [29 Mar 2010] | |
3341 | ||
3342 | *) Add "missing" function EVP_CIPHER_CTX_copy(). This copies a cipher | |
3343 | context. The operation can be customised via the ctrl mechanism in | |
3344 | case ENGINEs want to include additional functionality. | |
3345 | [Steve Henson] | |
3346 | ||
3347 | *) Tolerate yet another broken PKCS#8 key format: private key value negative. | |
3348 | [Steve Henson] | |
3349 | ||
3350 | *) Add new -subject_hash_old and -issuer_hash_old options to x509 utility to | |
3351 | output hashes compatible with older versions of OpenSSL. | |
3352 | [Willy Weisz <weisz@vcpc.univie.ac.at>] | |
3353 | ||
3354 | *) Fix compression algorithm handling: if resuming a session use the | |
3355 | compression algorithm of the resumed session instead of determining | |
3356 | it from client hello again. Don't allow server to change algorithm. | |
3357 | [Steve Henson] | |
3358 | ||
3359 | *) Add load_crls() function to apps tidying load_certs() too. Add option | |
3360 | to verify utility to allow additional CRLs to be included. | |
3361 | [Steve Henson] | |
3362 | ||
3363 | *) Update OCSP request code to permit adding custom headers to the request: | |
3364 | some responders need this. | |
3365 | [Steve Henson] | |
3366 | ||
3367 | *) The function EVP_PKEY_sign() returns <=0 on error: check return code | |
3368 | correctly. | |
3369 | [Julia Lawall <julia@diku.dk>] | |
3370 | ||
3371 | *) Update verify callback code in apps/s_cb.c and apps/verify.c, it | |
3372 | needlessly dereferenced structures, used obsolete functions and | |
3373 | didn't handle all updated verify codes correctly. | |
3374 | [Steve Henson] | |
3375 | ||
3376 | *) Disable MD2 in the default configuration. | |
3377 | [Steve Henson] | |
3378 | ||
3379 | *) In BIO_pop() and BIO_push() use the ctrl argument (which was NULL) to | |
3380 | indicate the initial BIO being pushed or popped. This makes it possible | |
3381 | to determine whether the BIO is the one explicitly called or as a result | |
3382 | of the ctrl being passed down the chain. Fix BIO_pop() and SSL BIOs so | |
3383 | it handles reference counts correctly and doesn't zero out the I/O bio | |
3384 | when it is not being explicitly popped. WARNING: applications which | |
3385 | included workarounds for the old buggy behaviour will need to be modified | |
3386 | or they could free up already freed BIOs. | |
3387 | [Steve Henson] | |
3388 | ||
3389 | *) Extend the uni2asc/asc2uni => OPENSSL_uni2asc/OPENSSL_asc2uni | |
3390 | renaming to all platforms (within the 0.9.8 branch, this was | |
3391 | done conditionally on Netware platforms to avoid a name clash). | |
3392 | [Guenter <lists@gknw.net>] | |
3393 | ||
3394 | *) Add ECDHE and PSK support to DTLS. | |
3395 | [Michael Tuexen <tuexen@fh-muenster.de>] | |
3396 | ||
3397 | *) Add CHECKED_STACK_OF macro to safestack.h, otherwise safestack can't | |
3398 | be used on C++. | |
3399 | [Steve Henson] | |
3400 | ||
3401 | *) Add "missing" function EVP_MD_flags() (without this the only way to | |
3402 | retrieve a digest flags is by accessing the structure directly. Update | |
3403 | EVP_MD_do_all*() and EVP_CIPHER_do_all*() to include the name a digest | |
3404 | or cipher is registered as in the "from" argument. Print out all | |
3405 | registered digests in the dgst usage message instead of manually | |
3406 | attempting to work them out. | |
3407 | [Steve Henson] | |
3408 | ||
3409 | *) If no SSLv2 ciphers are used don't use an SSLv2 compatible client hello: | |
3410 | this allows the use of compression and extensions. Change default cipher | |
3411 | string to remove SSLv2 ciphersuites. This effectively avoids ancient SSLv2 | |
3412 | by default unless an application cipher string requests it. | |
3413 | [Steve Henson] | |
3414 | ||
3415 | *) Alter match criteria in PKCS12_parse(). It used to try to use local | |
3416 | key ids to find matching certificates and keys but some PKCS#12 files | |
3417 | don't follow the (somewhat unwritten) rules and this strategy fails. | |
3418 | Now just gather all certificates together and the first private key | |
3419 | then look for the first certificate that matches the key. | |
3420 | [Steve Henson] | |
3421 | ||
3422 | *) Support use of registered digest and cipher names for dgst and cipher | |
3423 | commands instead of having to add each one as a special case. So now | |
3424 | you can do: | |
3425 | ||
3426 | openssl sha256 foo | |
3427 | ||
3428 | as well as: | |
3429 | ||
3430 | openssl dgst -sha256 foo | |
3431 | ||
3432 | and this works for ENGINE based algorithms too. | |
3433 | ||
3434 | [Steve Henson] | |
3435 | ||
3436 | *) Update Gost ENGINE to support parameter files. | |
3437 | [Victor B. Wagner <vitus@cryptocom.ru>] | |
3438 | ||
3439 | *) Support GeneralizedTime in ca utility. | |
3440 | [Oliver Martin <oliver@volatilevoid.net>, Steve Henson] | |
3441 | ||
3442 | *) Enhance the hash format used for certificate directory links. The new | |
3443 | form uses the canonical encoding (meaning equivalent names will work | |
3444 | even if they aren't identical) and uses SHA1 instead of MD5. This form | |
3445 | is incompatible with the older format and as a result c_rehash should | |
3446 | be used to rebuild symbolic links. | |
3447 | [Steve Henson] | |
3448 | ||
3449 | *) Make PKCS#8 the default write format for private keys, replacing the | |
3450 | traditional format. This form is standardised, more secure and doesn't | |
3451 | include an implicit MD5 dependency. | |
3452 | [Steve Henson] | |
3453 | ||
3454 | *) Add a $gcc_devteam_warn option to Configure. The idea is that any code | |
3455 | committed to OpenSSL should pass this lot as a minimum. | |
3456 | [Steve Henson] | |
3457 | ||
3458 | *) Add session ticket override functionality for use by EAP-FAST. | |
3459 | [Jouni Malinen <j@w1.fi>] | |
3460 | ||
3461 | *) Modify HMAC functions to return a value. Since these can be implemented | |
3462 | in an ENGINE errors can occur. | |
3463 | [Steve Henson] | |
3464 | ||
3465 | *) Type-checked OBJ_bsearch_ex. | |
3466 | [Ben Laurie] | |
3467 | ||
3468 | *) Type-checked OBJ_bsearch. Also some constification necessitated | |
3469 | by type-checking. Still to come: TXT_DB, bsearch(?), | |
3470 | OBJ_bsearch_ex, qsort, CRYPTO_EX_DATA, ASN1_VALUE, ASN1_STRING, | |
3471 | CONF_VALUE. | |
3472 | [Ben Laurie] | |
3473 | ||
3474 | *) New function OPENSSL_gmtime_adj() to add a specific number of days and | |
3475 | seconds to a tm structure directly, instead of going through OS | |
3476 | specific date routines. This avoids any issues with OS routines such | |
3477 | as the year 2038 bug. New *_adj() functions for ASN1 time structures | |
3478 | and X509_time_adj_ex() to cover the extended range. The existing | |
3479 | X509_time_adj() is still usable and will no longer have any date issues. | |
3480 | [Steve Henson] | |
3481 | ||
3482 | *) Delta CRL support. New use deltas option which will attempt to locate | |
3483 | and search any appropriate delta CRLs available. | |
3484 | ||
3485 | This work was sponsored by Google. | |
3486 | [Steve Henson] | |
3487 | ||
3488 | *) Support for CRLs partitioned by reason code. Reorganise CRL processing | |
3489 | code and add additional score elements. Validate alternate CRL paths | |
3490 | as part of the CRL checking and indicate a new error "CRL path validation | |
3491 | error" in this case. Applications wanting additional details can use | |
3492 | the verify callback and check the new "parent" field. If this is not | |
3493 | NULL CRL path validation is taking place. Existing applications won't | |
3494 | see this because it requires extended CRL support which is off by | |
3495 | default. | |
3496 | ||
3497 | This work was sponsored by Google. | |
3498 | [Steve Henson] | |
3499 | ||
3500 | *) Support for freshest CRL extension. | |
3501 | ||
3502 | This work was sponsored by Google. | |
3503 | [Steve Henson] | |
3504 | ||
3505 | *) Initial indirect CRL support. Currently only supported in the CRLs | |
3506 | passed directly and not via lookup. Process certificate issuer | |
3507 | CRL entry extension and lookup CRL entries by bother issuer name | |
3508 | and serial number. Check and process CRL issuer entry in IDP extension. | |
3509 | ||
3510 | This work was sponsored by Google. | |
3511 | [Steve Henson] | |
3512 | ||
3513 | *) Add support for distinct certificate and CRL paths. The CRL issuer | |
3514 | certificate is validated separately in this case. Only enabled if | |
3515 | an extended CRL support flag is set: this flag will enable additional | |
3516 | CRL functionality in future. | |
3517 | ||
3518 | This work was sponsored by Google. | |
3519 | [Steve Henson] | |
3520 | ||
3521 | *) Add support for policy mappings extension. | |
3522 | ||
3523 | This work was sponsored by Google. | |
3524 | [Steve Henson] | |
3525 | ||
3526 | *) Fixes to pathlength constraint, self issued certificate handling, | |
3527 | policy processing to align with RFC3280 and PKITS tests. | |
3528 | ||
3529 | This work was sponsored by Google. | |
3530 | [Steve Henson] | |
3531 | ||
3532 | *) Support for name constraints certificate extension. DN, email, DNS | |
3533 | and URI types are currently supported. | |
3534 | ||
3535 | This work was sponsored by Google. | |
3536 | [Steve Henson] | |
3537 | ||
3538 | *) To cater for systems that provide a pointer-based thread ID rather | |
3539 | than numeric, deprecate the current numeric thread ID mechanism and | |
3540 | replace it with a structure and associated callback type. This | |
3541 | mechanism allows a numeric "hash" to be extracted from a thread ID in | |
3542 | either case, and on platforms where pointers are larger than 'long', | |
3543 | mixing is done to help ensure the numeric 'hash' is usable even if it | |
3544 | can't be guaranteed unique. The default mechanism is to use "&errno" | |
3545 | as a pointer-based thread ID to distinguish between threads. | |
3546 | ||
3547 | Applications that want to provide their own thread IDs should now use | |
3548 | CRYPTO_THREADID_set_callback() to register a callback that will call | |
3549 | either CRYPTO_THREADID_set_numeric() or CRYPTO_THREADID_set_pointer(). | |
3550 | ||
3551 | Note that ERR_remove_state() is now deprecated, because it is tied | |
3552 | to the assumption that thread IDs are numeric. ERR_remove_state(0) | |
3553 | to free the current thread's error state should be replaced by | |
3554 | ERR_remove_thread_state(NULL). | |
3555 | ||
3556 | (This new approach replaces the functions CRYPTO_set_idptr_callback(), | |
3557 | CRYPTO_get_idptr_callback(), and CRYPTO_thread_idptr() that existed in | |
3558 | OpenSSL 0.9.9-dev between June 2006 and August 2008. Also, if an | |
3559 | application was previously providing a numeric thread callback that | |
3560 | was inappropriate for distinguishing threads, then uniqueness might | |
3561 | have been obtained with &errno that happened immediately in the | |
3562 | intermediate development versions of OpenSSL; this is no longer the | |
3563 | case, the numeric thread callback will now override the automatic use | |
3564 | of &errno.) | |
3565 | [Geoff Thorpe, with help from Bodo Moeller] | |
3566 | ||
3567 | *) Initial support for different CRL issuing certificates. This covers a | |
3568 | simple case where the self issued certificates in the chain exist and | |
3569 | the real CRL issuer is higher in the existing chain. | |
3570 | ||
3571 | This work was sponsored by Google. | |
3572 | [Steve Henson] | |
3573 | ||
3574 | *) Removed effectively defunct crypto/store from the build. | |
3575 | [Ben Laurie] | |
3576 | ||
3577 | *) Revamp of STACK to provide stronger type-checking. Still to come: | |
3578 | TXT_DB, bsearch(?), OBJ_bsearch, qsort, CRYPTO_EX_DATA, ASN1_VALUE, | |
3579 | ASN1_STRING, CONF_VALUE. | |
3580 | [Ben Laurie] | |
3581 | ||
3582 | *) Add a new SSL_MODE_RELEASE_BUFFERS mode flag to release unused buffer | |
3583 | RAM on SSL connections. This option can save about 34k per idle SSL. | |
3584 | [Nick Mathewson] | |
3585 | ||
3586 | *) Revamp of LHASH to provide stronger type-checking. Still to come: | |
3587 | STACK, TXT_DB, bsearch, qsort. | |
3588 | [Ben Laurie] | |
3589 | ||
3590 | *) Initial support for Cryptographic Message Syntax (aka CMS) based | |
3591 | on RFC3850, RFC3851 and RFC3852. New cms directory and cms utility, | |
3592 | support for data, signedData, compressedData, digestedData and | |
3593 | encryptedData, envelopedData types included. Scripts to check against | |
3594 | RFC4134 examples draft and interop and consistency checks of many | |
3595 | content types and variants. | |
3596 | [Steve Henson] | |
3597 | ||
3598 | *) Add options to enc utility to support use of zlib compression BIO. | |
3599 | [Steve Henson] | |
3600 | ||
3601 | *) Extend mk1mf to support importing of options and assembly language | |
3602 | files from Configure script, currently only included in VC-WIN32. | |
3603 | The assembly language rules can now optionally generate the source | |
3604 | files from the associated perl scripts. | |
3605 | [Steve Henson] | |
3606 | ||
3607 | *) Implement remaining functionality needed to support GOST ciphersuites. | |
3608 | Interop testing has been performed using CryptoPro implementations. | |
3609 | [Victor B. Wagner <vitus@cryptocom.ru>] | |
3610 | ||
3611 | *) s390x assembler pack. | |
3612 | [Andy Polyakov] | |
3613 | ||
3614 | *) ARMv4 assembler pack. ARMv4 refers to v4 and later ISA, not CPU | |
3615 | "family." | |
3616 | [Andy Polyakov] | |
3617 | ||
3618 | *) Implement Opaque PRF Input TLS extension as specified in | |
3619 | draft-rescorla-tls-opaque-prf-input-00.txt. Since this is not an | |
3620 | official specification yet and no extension type assignment by | |
3621 | IANA exists, this extension (for now) will have to be explicitly | |
3622 | enabled when building OpenSSL by providing the extension number | |
3623 | to use. For example, specify an option | |
3624 | ||
3625 | -DTLSEXT_TYPE_opaque_prf_input=0x9527 | |
3626 | ||
3627 | to the "config" or "Configure" script to enable the extension, | |
3628 | assuming extension number 0x9527 (which is a completely arbitrary | |
3629 | and unofficial assignment based on the MD5 hash of the Internet | |
3630 | Draft). Note that by doing so, you potentially lose | |
3631 | interoperability with other TLS implementations since these might | |
3632 | be using the same extension number for other purposes. | |
3633 | ||
3634 | SSL_set_tlsext_opaque_prf_input(ssl, src, len) is used to set the | |
3635 | opaque PRF input value to use in the handshake. This will create | |
3636 | an internal copy of the length-'len' string at 'src', and will | |
3637 | return non-zero for success. | |
3638 | ||
3639 | To get more control and flexibility, provide a callback function | |
3640 | by using | |
3641 | ||
3642 | SSL_CTX_set_tlsext_opaque_prf_input_callback(ctx, cb) | |
3643 | SSL_CTX_set_tlsext_opaque_prf_input_callback_arg(ctx, arg) | |
3644 | ||
3645 | where | |
3646 | ||
3647 | int (*cb)(SSL *, void *peerinput, size_t len, void *arg); | |
3648 | void *arg; | |
3649 | ||
3650 | Callback function 'cb' will be called in handshakes, and is | |
3651 | expected to use SSL_set_tlsext_opaque_prf_input() as appropriate. | |
3652 | Argument 'arg' is for application purposes (the value as given to | |
3653 | SSL_CTX_set_tlsext_opaque_prf_input_callback_arg() will directly | |
3654 | be provided to the callback function). The callback function | |
3655 | has to return non-zero to report success: usually 1 to use opaque | |
3656 | PRF input just if possible, or 2 to enforce use of the opaque PRF | |
3657 | input. In the latter case, the library will abort the handshake | |
3658 | if opaque PRF input is not successfully negotiated. | |
3659 | ||
3660 | Arguments 'peerinput' and 'len' given to the callback function | |
3661 | will always be NULL and 0 in the case of a client. A server will | |
3662 | see the client's opaque PRF input through these variables if | |
3663 | available (NULL and 0 otherwise). Note that if the server | |
3664 | provides an opaque PRF input, the length must be the same as the | |
3665 | length of the client's opaque PRF input. | |
3666 | ||
3667 | Note that the callback function will only be called when creating | |
3668 | a new session (session resumption can resume whatever was | |
3669 | previously negotiated), and will not be called in SSL 2.0 | |
3670 | handshakes; thus, SSL_CTX_set_options(ctx, SSL_OP_NO_SSLv2) or | |
3671 | SSL_set_options(ssl, SSL_OP_NO_SSLv2) is especially recommended | |
3672 | for applications that need to enforce opaque PRF input. | |
3673 | ||
3674 | [Bodo Moeller] | |
3675 | ||
3676 | *) Update ssl code to support digests other than SHA1+MD5 for handshake | |
3677 | MAC. | |
3678 | ||
3679 | [Victor B. Wagner <vitus@cryptocom.ru>] | |
3680 | ||
3681 | *) Add RFC4507 support to OpenSSL. This includes the corrections in | |
3682 | RFC4507bis. The encrypted ticket format is an encrypted encoded | |
3683 | SSL_SESSION structure, that way new session features are automatically | |
3684 | supported. | |
3685 | ||
3686 | If a client application caches session in an SSL_SESSION structure | |
3687 | support is transparent because tickets are now stored in the encoded | |
3688 | SSL_SESSION. | |
3689 | ||
3690 | The SSL_CTX structure automatically generates keys for ticket | |
3691 | protection in servers so again support should be possible | |
3692 | with no application modification. | |
3693 | ||
3694 | If a client or server wishes to disable RFC4507 support then the option | |
3695 | SSL_OP_NO_TICKET can be set. | |
3696 | ||
3697 | Add a TLS extension debugging callback to allow the contents of any client | |
3698 | or server extensions to be examined. | |
3699 | ||
3700 | This work was sponsored by Google. | |
3701 | [Steve Henson] | |
3702 | ||
3703 | *) Final changes to avoid use of pointer pointer casts in OpenSSL. | |
3704 | OpenSSL should now compile cleanly on gcc 4.2 | |
3705 | [Peter Hartley <pdh@utter.chaos.org.uk>, Steve Henson] | |
3706 | ||
3707 | *) Update SSL library to use new EVP_PKEY MAC API. Include generic MAC | |
3708 | support including streaming MAC support: this is required for GOST | |
3709 | ciphersuite support. | |
3710 | [Victor B. Wagner <vitus@cryptocom.ru>, Steve Henson] | |
3711 | ||
3712 | *) Add option -stream to use PKCS#7 streaming in smime utility. New | |
3713 | function i2d_PKCS7_bio_stream() and PEM_write_PKCS7_bio_stream() | |
3714 | to output in BER and PEM format. | |
3715 | [Steve Henson] | |
3716 | ||
3717 | *) Experimental support for use of HMAC via EVP_PKEY interface. This | |
3718 | allows HMAC to be handled via the EVP_DigestSign*() interface. The | |
3719 | EVP_PKEY "key" in this case is the HMAC key, potentially allowing | |
3720 | ENGINE support for HMAC keys which are unextractable. New -mac and | |
3721 | -macopt options to dgst utility. | |
3722 | [Steve Henson] | |
3723 | ||
3724 | *) New option -sigopt to dgst utility. Update dgst to use | |
3725 | EVP_Digest{Sign,Verify}*. These two changes make it possible to use | |
3726 | alternative signing parameters such as X9.31 or PSS in the dgst | |
3727 | utility. | |
3728 | [Steve Henson] | |
3729 | ||
3730 | *) Change ssl_cipher_apply_rule(), the internal function that does | |
3731 | the work each time a ciphersuite string requests enabling | |
3732 | ("foo+bar"), moving ("+foo+bar"), disabling ("-foo+bar", or | |
3733 | removing ("!foo+bar") a class of ciphersuites: Now it maintains | |
3734 | the order of disabled ciphersuites such that those ciphersuites | |
3735 | that most recently went from enabled to disabled not only stay | |
3736 | in order with respect to each other, but also have higher priority | |
3737 | than other disabled ciphersuites the next time ciphersuites are | |
3738 | enabled again. | |
3739 | ||
3740 | This means that you can now say, e.g., "PSK:-PSK:HIGH" to enable | |
3741 | the same ciphersuites as with "HIGH" alone, but in a specific | |
3742 | order where the PSK ciphersuites come first (since they are the | |
3743 | most recently disabled ciphersuites when "HIGH" is parsed). | |
3744 | ||
3745 | Also, change ssl_create_cipher_list() (using this new | |
3746 | functionality) such that between otherwise identical | |
3747 | ciphersuites, ephemeral ECDH is preferred over ephemeral DH in | |
3748 | the default order. | |
3749 | [Bodo Moeller] | |
3750 | ||
3751 | *) Change ssl_create_cipher_list() so that it automatically | |
3752 | arranges the ciphersuites in reasonable order before starting | |
3753 | to process the rule string. Thus, the definition for "DEFAULT" | |
3754 | (SSL_DEFAULT_CIPHER_LIST) now is just "ALL:!aNULL:!eNULL", but | |
3755 | remains equivalent to "AES:ALL:!aNULL:!eNULL:+aECDH:+kRSA:+RC4:@STRENGTH". | |
3756 | This makes it much easier to arrive at a reasonable default order | |
3757 | in applications for which anonymous ciphers are OK (meaning | |
3758 | that you can't actually use DEFAULT). | |
3759 | [Bodo Moeller; suggested by Victor Duchovni] | |
3760 | ||
3761 | *) Split the SSL/TLS algorithm mask (as used for ciphersuite string | |
3762 | processing) into multiple integers instead of setting | |
3763 | "SSL_MKEY_MASK" bits, "SSL_AUTH_MASK" bits, "SSL_ENC_MASK", | |
3764 | "SSL_MAC_MASK", and "SSL_SSL_MASK" bits all in a single integer. | |
3765 | (These masks as well as the individual bit definitions are hidden | |
3766 | away into the non-exported interface ssl/ssl_locl.h, so this | |
3767 | change to the definition of the SSL_CIPHER structure shouldn't | |
3768 | affect applications.) This give us more bits for each of these | |
3769 | categories, so there is no longer a need to coagulate AES128 and | |
3770 | AES256 into a single algorithm bit, and to coagulate Camellia128 | |
3771 | and Camellia256 into a single algorithm bit, which has led to all | |
3772 | kinds of kludges. | |
3773 | ||
3774 | Thus, among other things, the kludge introduced in 0.9.7m and | |
3775 | 0.9.8e for masking out AES256 independently of AES128 or masking | |
3776 | out Camellia256 independently of AES256 is not needed here in 0.9.9. | |
3777 | ||
3778 | With the change, we also introduce new ciphersuite aliases that | |
3779 | so far were missing: "AES128", "AES256", "CAMELLIA128", and | |
3780 | "CAMELLIA256". | |
3781 | [Bodo Moeller] | |
3782 | ||
3783 | *) Add support for dsa-with-SHA224 and dsa-with-SHA256. | |
3784 | Use the leftmost N bytes of the signature input if the input is | |
3785 | larger than the prime q (with N being the size in bytes of q). | |
3786 | [Nils Larsch] | |
3787 | ||
3788 | *) Very *very* experimental PKCS#7 streaming encoder support. Nothing uses | |
3789 | it yet and it is largely untested. | |
3790 | [Steve Henson] | |
3791 | ||
3792 | *) Add support for the ecdsa-with-SHA224/256/384/512 signature types. | |
3793 | [Nils Larsch] | |
3794 | ||
3795 | *) Initial incomplete changes to avoid need for function casts in OpenSSL | |
3796 | some compilers (gcc 4.2 and later) reject their use. Safestack is | |
3797 | reimplemented. Update ASN1 to avoid use of legacy functions. | |
3798 | [Steve Henson] | |
3799 | ||
3800 | *) Win32/64 targets are linked with Winsock2. | |
3801 | [Andy Polyakov] | |
3802 | ||
3803 | *) Add an X509_CRL_METHOD structure to allow CRL processing to be redirected | |
3804 | to external functions. This can be used to increase CRL handling | |
3805 | efficiency especially when CRLs are very large by (for example) storing | |
3806 | the CRL revoked certificates in a database. | |
3807 | [Steve Henson] | |
3808 | ||
3809 | *) Overhaul of by_dir code. Add support for dynamic loading of CRLs so | |
3810 | new CRLs added to a directory can be used. New command line option | |
3811 | -verify_return_error to s_client and s_server. This causes real errors | |
3812 | to be returned by the verify callback instead of carrying on no matter | |
3813 | what. This reflects the way a "real world" verify callback would behave. | |
3814 | [Steve Henson] | |
3815 | ||
3816 | *) GOST engine, supporting several GOST algorithms and public key formats. | |
3817 | Kindly donated by Cryptocom. | |
3818 | [Cryptocom] | |
3819 | ||
3820 | *) Partial support for Issuing Distribution Point CRL extension. CRLs | |
3821 | partitioned by DP are handled but no indirect CRL or reason partitioning | |
3822 | (yet). Complete overhaul of CRL handling: now the most suitable CRL is | |
3823 | selected via a scoring technique which handles IDP and AKID in CRLs. | |
3824 | [Steve Henson] | |
3825 | ||
3826 | *) New X509_STORE_CTX callbacks lookup_crls() and lookup_certs() which | |
3827 | will ultimately be used for all verify operations: this will remove the | |
3828 | X509_STORE dependency on certificate verification and allow alternative | |
3829 | lookup methods. X509_STORE based implementations of these two callbacks. | |
3830 | [Steve Henson] | |
3831 | ||
3832 | *) Allow multiple CRLs to exist in an X509_STORE with matching issuer names. | |
3833 | Modify get_crl() to find a valid (unexpired) CRL if possible. | |
3834 | [Steve Henson] | |
3835 | ||
3836 | *) New function X509_CRL_match() to check if two CRLs are identical. Normally | |
3837 | this would be called X509_CRL_cmp() but that name is already used by | |
3838 | a function that just compares CRL issuer names. Cache several CRL | |
3839 | extensions in X509_CRL structure and cache CRLDP in X509. | |
3840 | [Steve Henson] | |
3841 | ||
3842 | *) Store a "canonical" representation of X509_NAME structure (ASN1 Name) | |
3843 | this maps equivalent X509_NAME structures into a consistent structure. | |
3844 | Name comparison can then be performed rapidly using memcmp(). | |
3845 | [Steve Henson] | |
3846 | ||
3847 | *) Non-blocking OCSP request processing. Add -timeout option to ocsp | |
3848 | utility. | |
3849 | [Steve Henson] | |
3850 | ||
3851 | *) Allow digests to supply their own micalg string for S/MIME type using | |
3852 | the ctrl EVP_MD_CTRL_MICALG. | |
3853 | [Steve Henson] | |
3854 | ||
3855 | *) During PKCS7 signing pass the PKCS7 SignerInfo structure to the | |
3856 | EVP_PKEY_METHOD before and after signing via the EVP_PKEY_CTRL_PKCS7_SIGN | |
3857 | ctrl. It can then customise the structure before and/or after signing | |
3858 | if necessary. | |
3859 | [Steve Henson] | |
3860 | ||
3861 | *) New function OBJ_add_sigid() to allow application defined signature OIDs | |
3862 | to be added to OpenSSLs internal tables. New function OBJ_sigid_free() | |
3863 | to free up any added signature OIDs. | |
3864 | [Steve Henson] | |
3865 | ||
3866 | *) New functions EVP_CIPHER_do_all(), EVP_CIPHER_do_all_sorted(), | |
3867 | EVP_MD_do_all() and EVP_MD_do_all_sorted() to enumerate internal | |
3868 | digest and cipher tables. New options added to openssl utility: | |
3869 | list-message-digest-algorithms and list-cipher-algorithms. | |
3870 | [Steve Henson] | |
3871 | ||
3872 | *) Change the array representation of binary polynomials: the list | |
3873 | of degrees of non-zero coefficients is now terminated with -1. | |
3874 | Previously it was terminated with 0, which was also part of the | |
3875 | value; thus, the array representation was not applicable to | |
3876 | polynomials where t^0 has coefficient zero. This change makes | |
3877 | the array representation useful in a more general context. | |
3878 | [Douglas Stebila] | |
3879 | ||
3880 | *) Various modifications and fixes to SSL/TLS cipher string | |
3881 | handling. For ECC, the code now distinguishes between fixed ECDH | |
3882 | with RSA certificates on the one hand and with ECDSA certificates | |
3883 | on the other hand, since these are separate ciphersuites. The | |
3884 | unused code for Fortezza ciphersuites has been removed. | |
3885 | ||
3886 | For consistency with EDH, ephemeral ECDH is now called "EECDH" | |
3887 | (not "ECDHE"). For consistency with the code for DH | |
3888 | certificates, use of ECDH certificates is now considered ECDH | |
3889 | authentication, not RSA or ECDSA authentication (the latter is | |
3890 | merely the CA's signing algorithm and not actively used in the | |
3891 | protocol). | |
3892 | ||
3893 | The temporary ciphersuite alias "ECCdraft" is no longer | |
3894 | available, and ECC ciphersuites are no longer excluded from "ALL" | |
3895 | and "DEFAULT". The following aliases now exist for RFC 4492 | |
3896 | ciphersuites, most of these by analogy with the DH case: | |
3897 | ||
3898 | kECDHr - ECDH cert, signed with RSA | |
3899 | kECDHe - ECDH cert, signed with ECDSA | |
3900 | kECDH - ECDH cert (signed with either RSA or ECDSA) | |
3901 | kEECDH - ephemeral ECDH | |
3902 | ECDH - ECDH cert or ephemeral ECDH | |
3903 | ||
3904 | aECDH - ECDH cert | |
3905 | aECDSA - ECDSA cert | |
3906 | ECDSA - ECDSA cert | |
3907 | ||
3908 | AECDH - anonymous ECDH | |
3909 | EECDH - non-anonymous ephemeral ECDH (equivalent to "kEECDH:-AECDH") | |
3910 | ||
3911 | [Bodo Moeller] | |
3912 | ||
3913 | *) Add additional S/MIME capabilities for AES and GOST ciphers if supported. | |
3914 | Use correct micalg parameters depending on digest(s) in signed message. | |
3915 | [Steve Henson] | |
3916 | ||
3917 | *) Add engine support for EVP_PKEY_ASN1_METHOD. Add functions to process | |
3918 | an ENGINE asn1 method. Support ENGINE lookups in the ASN1 code. | |
3919 | [Steve Henson] | |
3920 | ||
3921 | *) Initial engine support for EVP_PKEY_METHOD. New functions to permit | |
3922 | an engine to register a method. Add ENGINE lookups for methods and | |
3923 | functional reference processing. | |
3924 | [Steve Henson] | |
3925 | ||
3926 | *) New functions EVP_Digest{Sign,Verify)*. These are enhanced versions of | |
3927 | EVP_{Sign,Verify}* which allow an application to customise the signature | |
3928 | process. | |
3929 | [Steve Henson] | |
3930 | ||
3931 | *) New -resign option to smime utility. This adds one or more signers | |
3932 | to an existing PKCS#7 signedData structure. Also -md option to use an | |
3933 | alternative message digest algorithm for signing. | |
3934 | [Steve Henson] | |
3935 | ||
3936 | *) Tidy up PKCS#7 routines and add new functions to make it easier to | |
3937 | create PKCS7 structures containing multiple signers. Update smime | |
3938 | application to support multiple signers. | |
3939 | [Steve Henson] | |
3940 | ||
3941 | *) New -macalg option to pkcs12 utility to allow setting of an alternative | |
3942 | digest MAC. | |
3943 | [Steve Henson] | |
3944 | ||
3945 | *) Initial support for PKCS#5 v2.0 PRFs other than default SHA1 HMAC. | |
3946 | Reorganize PBE internals to lookup from a static table using NIDs, | |
3947 | add support for HMAC PBE OID translation. Add a EVP_CIPHER ctrl: | |
3948 | EVP_CTRL_PBE_PRF_NID this allows a cipher to specify an alternative | |
3949 | PRF which will be automatically used with PBES2. | |
3950 | [Steve Henson] | |
3951 | ||
3952 | *) Replace the algorithm specific calls to generate keys in "req" with the | |
3953 | new API. | |
3954 | [Steve Henson] | |
3955 | ||
3956 | *) Update PKCS#7 enveloped data routines to use new API. This is now | |
3957 | supported by any public key method supporting the encrypt operation. A | |
3958 | ctrl is added to allow the public key algorithm to examine or modify | |
3959 | the PKCS#7 RecipientInfo structure if it needs to: for RSA this is | |
3960 | a no op. | |
3961 | [Steve Henson] | |
3962 | ||
3963 | *) Add a ctrl to asn1 method to allow a public key algorithm to express | |
3964 | a default digest type to use. In most cases this will be SHA1 but some | |
3965 | algorithms (such as GOST) need to specify an alternative digest. The | |
3966 | return value indicates how strong the preference is 1 means optional and | |
3967 | 2 is mandatory (that is it is the only supported type). Modify | |
3968 | ASN1_item_sign() to accept a NULL digest argument to indicate it should | |
3969 | use the default md. Update openssl utilities to use the default digest | |
3970 | type for signing if it is not explicitly indicated. | |
3971 | [Steve Henson] | |
3972 | ||
3973 | *) Use OID cross reference table in ASN1_sign() and ASN1_verify(). New | |
3974 | EVP_MD flag EVP_MD_FLAG_PKEY_METHOD_SIGNATURE. This uses the relevant | |
3975 | signing method from the key type. This effectively removes the link | |
3976 | between digests and public key types. | |
3977 | [Steve Henson] | |
3978 | ||
3979 | *) Add an OID cross reference table and utility functions. Its purpose is to | |
3980 | translate between signature OIDs such as SHA1WithrsaEncryption and SHA1, | |
3981 | rsaEncryption. This will allow some of the algorithm specific hackery | |
3982 | needed to use the correct OID to be removed. | |
3983 | [Steve Henson] | |
3984 | ||
3985 | *) Remove algorithm specific dependencies when setting PKCS7_SIGNER_INFO | |
3986 | structures for PKCS7_sign(). They are now set up by the relevant public | |
3987 | key ASN1 method. | |
3988 | [Steve Henson] | |
3989 | ||
3990 | *) Add provisional EC pkey method with support for ECDSA and ECDH. | |
3991 | [Steve Henson] | |
3992 | ||
3993 | *) Add support for key derivation (agreement) in the API, DH method and | |
3994 | pkeyutl. | |
3995 | [Steve Henson] | |
3996 | ||
3997 | *) Add DSA pkey method and DH pkey methods, extend DH ASN1 method to support | |
3998 | public and private key formats. As a side effect these add additional | |
3999 | command line functionality not previously available: DSA signatures can be | |
4000 | generated and verified using pkeyutl and DH key support and generation in | |
4001 | pkey, genpkey. | |
4002 | [Steve Henson] | |
4003 | ||
4004 | *) BeOS support. | |
4005 | [Oliver Tappe <zooey@hirschkaefer.de>] | |
4006 | ||
4007 | *) New make target "install_html_docs" installs HTML renditions of the | |
4008 | manual pages. | |
4009 | [Oliver Tappe <zooey@hirschkaefer.de>] | |
4010 | ||
4011 | *) New utility "genpkey" this is analogous to "genrsa" etc except it can | |
4012 | generate keys for any algorithm. Extend and update EVP_PKEY_METHOD to | |
4013 | support key and parameter generation and add initial key generation | |
4014 | functionality for RSA. | |
4015 | [Steve Henson] | |
4016 | ||
4017 | *) Add functions for main EVP_PKEY_method operations. The undocumented | |
4018 | functions EVP_PKEY_{encrypt,decrypt} have been renamed to | |
4019 | EVP_PKEY_{encrypt,decrypt}_old. | |
4020 | [Steve Henson] | |
4021 | ||
4022 | *) Initial definitions for EVP_PKEY_METHOD. This will be a high level public | |
4023 | key API, doesn't do much yet. | |
4024 | [Steve Henson] | |
4025 | ||
4026 | *) New function EVP_PKEY_asn1_get0_info() to retrieve information about | |
4027 | public key algorithms. New option to openssl utility: | |
4028 | "list-public-key-algorithms" to print out info. | |
4029 | [Steve Henson] | |
4030 | ||
4031 | *) Implement the Supported Elliptic Curves Extension for | |
4032 | ECC ciphersuites from draft-ietf-tls-ecc-12.txt. | |
4033 | [Douglas Stebila] | |
4034 | ||
4035 | *) Don't free up OIDs in OBJ_cleanup() if they are in use by EVP_MD or | |
4036 | EVP_CIPHER structures to avoid later problems in EVP_cleanup(). | |
4037 | [Steve Henson] | |
4038 | ||
4039 | *) New utilities pkey and pkeyparam. These are similar to algorithm specific | |
4040 | utilities such as rsa, dsa, dsaparam etc except they process any key | |
4041 | type. | |
4042 | [Steve Henson] | |
4043 | ||
4044 | *) Transfer public key printing routines to EVP_PKEY_ASN1_METHOD. New | |
4045 | functions EVP_PKEY_print_public(), EVP_PKEY_print_private(), | |
4046 | EVP_PKEY_print_param() to print public key data from an EVP_PKEY | |
4047 | structure. | |
4048 | [Steve Henson] | |
4049 | ||
4050 | *) Initial support for pluggable public key ASN1. | |
4051 | De-spaghettify the public key ASN1 handling. Move public and private | |
4052 | key ASN1 handling to a new EVP_PKEY_ASN1_METHOD structure. Relocate | |
4053 | algorithm specific handling to a single module within the relevant | |
4054 | algorithm directory. Add functions to allow (near) opaque processing | |
4055 | of public and private key structures. | |
4056 | [Steve Henson] | |
4057 | ||
4058 | *) Implement the Supported Point Formats Extension for | |
4059 | ECC ciphersuites from draft-ietf-tls-ecc-12.txt. | |
4060 | [Douglas Stebila] | |
4061 | ||
4062 | *) Add initial support for RFC 4279 PSK TLS ciphersuites. Add members | |
4063 | for the psk identity [hint] and the psk callback functions to the | |
4064 | SSL_SESSION, SSL and SSL_CTX structure. | |
4065 | ||
4066 | New ciphersuites: | |
4067 | PSK-RC4-SHA, PSK-3DES-EDE-CBC-SHA, PSK-AES128-CBC-SHA, | |
4068 | PSK-AES256-CBC-SHA | |
4069 | ||
4070 | New functions: | |
4071 | SSL_CTX_use_psk_identity_hint | |
4072 | SSL_get_psk_identity_hint | |
4073 | SSL_get_psk_identity | |
4074 | SSL_use_psk_identity_hint | |
4075 | ||
4076 | [Mika Kousa and Pasi Eronen of Nokia Corporation] | |
4077 | ||
4078 | *) Add RFC 3161 compliant time stamp request creation, response generation | |
4079 | and response verification functionality. | |
4080 | [Zoltán Glózik <zglozik@opentsa.org>, The OpenTSA Project] | |
4081 | ||
4082 | *) Add initial support for TLS extensions, specifically for the server_name | |
4083 | extension so far. The SSL_SESSION, SSL_CTX, and SSL data structures now | |
4084 | have new members for a host name. The SSL data structure has an | |
4085 | additional member SSL_CTX *initial_ctx so that new sessions can be | |
4086 | stored in that context to allow for session resumption, even after the | |
4087 | SSL has been switched to a new SSL_CTX in reaction to a client's | |
4088 | server_name extension. | |
4089 | ||
4090 | New functions (subject to change): | |
4091 | ||
4092 | SSL_get_servername() | |
4093 | SSL_get_servername_type() | |
4094 | SSL_set_SSL_CTX() | |
4095 | ||
4096 | New CTRL codes and macros (subject to change): | |
4097 | ||
4098 | SSL_CTRL_SET_TLSEXT_SERVERNAME_CB | |
4099 | - SSL_CTX_set_tlsext_servername_callback() | |
4100 | SSL_CTRL_SET_TLSEXT_SERVERNAME_ARG | |
4101 | - SSL_CTX_set_tlsext_servername_arg() | |
4102 | SSL_CTRL_SET_TLSEXT_HOSTNAME - SSL_set_tlsext_host_name() | |
4103 | ||
4104 | openssl s_client has a new '-servername ...' option. | |
4105 | ||
4106 | openssl s_server has new options '-servername_host ...', '-cert2 ...', | |
4107 | '-key2 ...', '-servername_fatal' (subject to change). This allows | |
4108 | testing the HostName extension for a specific single host name ('-cert' | |
4109 | and '-key' remain fallbacks for handshakes without HostName | |
4110 | negotiation). If the unrecognized_name alert has to be sent, this by | |
4111 | default is a warning; it becomes fatal with the '-servername_fatal' | |
4112 | option. | |
4113 | ||
4114 | [Peter Sylvester, Remy Allais, Christophe Renou] | |
4115 | ||
4116 | *) Whirlpool hash implementation is added. | |
4117 | [Andy Polyakov] | |
4118 | ||
4119 | *) BIGNUM code on 64-bit SPARCv9 targets is switched from bn(64,64) to | |
4120 | bn(64,32). Because of instruction set limitations it doesn't have | |
4121 | any negative impact on performance. This was done mostly in order | |
4122 | to make it possible to share assembler modules, such as bn_mul_mont | |
4123 | implementations, between 32- and 64-bit builds without hassle. | |
4124 | [Andy Polyakov] | |
4125 | ||
4126 | *) Move code previously exiled into file crypto/ec/ec2_smpt.c | |
4127 | to ec2_smpl.c, and no longer require the OPENSSL_EC_BIN_PT_COMP | |
4128 | macro. | |
4129 | [Bodo Moeller] | |
4130 | ||
4131 | *) New candidate for BIGNUM assembler implementation, bn_mul_mont, | |
4132 | dedicated Montgomery multiplication procedure, is introduced. | |
4133 | BN_MONT_CTX is modified to allow bn_mul_mont to reach for higher | |
4134 | "64-bit" performance on certain 32-bit targets. | |
4135 | [Andy Polyakov] | |
4136 | ||
4137 | *) New option SSL_OP_NO_COMP to disable use of compression selectively | |
4138 | in SSL structures. New SSL ctrl to set maximum send fragment size. | |
4139 | Save memory by setting the I/O buffer sizes dynamically instead of | |
4140 | using the maximum available value. | |
4141 | [Steve Henson] | |
4142 | ||
4143 | *) New option -V for 'openssl ciphers'. This prints the ciphersuite code | |
4144 | in addition to the text details. | |
4145 | [Bodo Moeller] | |
4146 | ||
4147 | *) Very, very preliminary EXPERIMENTAL support for printing of general | |
4148 | ASN1 structures. This currently produces rather ugly output and doesn't | |
4149 | handle several customised structures at all. | |
4150 | [Steve Henson] | |
4151 | ||
4152 | *) Integrated support for PVK file format and some related formats such | |
4153 | as MS PUBLICKEYBLOB and PRIVATEKEYBLOB. Command line switches to support | |
4154 | these in the 'rsa' and 'dsa' utilities. | |
4155 | [Steve Henson] | |
4156 | ||
4157 | *) Support for PKCS#1 RSAPublicKey format on rsa utility command line. | |
4158 | [Steve Henson] | |
4159 | ||
4160 | *) Remove the ancient ASN1_METHOD code. This was only ever used in one | |
4161 | place for the (very old) "NETSCAPE" format certificates which are now | |
4162 | handled using new ASN1 code equivalents. | |
4163 | [Steve Henson] | |
4164 | ||
4165 | *) Let the TLSv1_method() etc. functions return a 'const' SSL_METHOD | |
4166 | pointer and make the SSL_METHOD parameter in SSL_CTX_new, | |
4167 | SSL_CTX_set_ssl_version and SSL_set_ssl_method 'const'. | |
4168 | [Nils Larsch] | |
4169 | ||
4170 | *) Modify CRL distribution points extension code to print out previously | |
4171 | unsupported fields. Enhance extension setting code to allow setting of | |
4172 | all fields. | |
4173 | [Steve Henson] | |
4174 | ||
4175 | *) Add print and set support for Issuing Distribution Point CRL extension. | |
4176 | [Steve Henson] | |
4177 | ||
4178 | *) Change 'Configure' script to enable Camellia by default. | |
4179 | [NTT] | |
4180 | ||
4181 | Changes between 0.9.8m and 0.9.8n [24 Mar 2010] | |
4182 | ||
4183 | *) When rejecting SSL/TLS records due to an incorrect version number, never | |
4184 | update s->server with a new major version number. As of | |
4185 | - OpenSSL 0.9.8m if 'short' is a 16-bit type, | |
4186 | - OpenSSL 0.9.8f if 'short' is longer than 16 bits, | |
4187 | the previous behavior could result in a read attempt at NULL when | |
4188 | receiving specific incorrect SSL/TLS records once record payload | |
4189 | protection is active. (CVE-2010-0740) | |
4190 | [Bodo Moeller, Adam Langley <agl@chromium.org>] | |
4191 | ||
4192 | *) Fix for CVE-2010-0433 where some kerberos enabled versions of OpenSSL | |
4193 | could be crashed if the relevant tables were not present (e.g. chrooted). | |
4194 | [Tomas Hoger <thoger@redhat.com>] | |
4195 | ||
4196 | Changes between 0.9.8l and 0.9.8m [25 Feb 2010] | |
4197 | ||
4198 | *) Always check bn_wexpand() return values for failure. (CVE-2009-3245) | |
4199 | [Martin Olsson, Neel Mehta] | |
4200 | ||
4201 | *) Fix X509_STORE locking: Every 'objs' access requires a lock (to | |
4202 | accommodate for stack sorting, always a write lock!). | |
4203 | [Bodo Moeller] | |
4204 | ||
4205 | *) On some versions of WIN32 Heap32Next is very slow. This can cause | |
4206 | excessive delays in the RAND_poll(): over a minute. As a workaround | |
4207 | include a time check in the inner Heap32Next loop too. | |
4208 | [Steve Henson] | |
4209 | ||
4210 | *) The code that handled flushing of data in SSL/TLS originally used the | |
4211 | BIO_CTRL_INFO ctrl to see if any data was pending first. This caused | |
4212 | the problem outlined in PR#1949. The fix suggested there however can | |
4213 | trigger problems with buggy BIO_CTRL_WPENDING (e.g. some versions | |
4214 | of Apache). So instead simplify the code to flush unconditionally. | |
4215 | This should be fine since flushing with no data to flush is a no op. | |
4216 | [Steve Henson] | |
4217 | ||
4218 | *) Handle TLS versions 2.0 and later properly and correctly use the | |
4219 | highest version of TLS/SSL supported. Although TLS >= 2.0 is some way | |
4220 | off ancient servers have a habit of sticking around for a while... | |
4221 | [Steve Henson] | |
4222 | ||
4223 | *) Modify compression code so it frees up structures without using the | |
4224 | ex_data callbacks. This works around a problem where some applications | |
4225 | call CRYPTO_cleanup_all_ex_data() before application exit (e.g. when | |
4226 | restarting) then use compression (e.g. SSL with compression) later. | |
4227 | This results in significant per-connection memory leaks and | |
4228 | has caused some security issues including CVE-2008-1678 and | |
4229 | CVE-2009-4355. | |
4230 | [Steve Henson] | |
4231 | ||
4232 | *) Constify crypto/cast (i.e., <openssl/cast.h>): a CAST_KEY doesn't | |
4233 | change when encrypting or decrypting. | |
4234 | [Bodo Moeller] | |
4235 | ||
4236 | *) Add option SSL_OP_LEGACY_SERVER_CONNECT which will allow clients to | |
4237 | connect and renegotiate with servers which do not support RI. | |
4238 | Until RI is more widely deployed this option is enabled by default. | |
4239 | [Steve Henson] | |
4240 | ||
4241 | *) Add "missing" ssl ctrls to clear options and mode. | |
4242 | [Steve Henson] | |
4243 | ||
4244 | *) If client attempts to renegotiate and doesn't support RI respond with | |
4245 | a no_renegotiation alert as required by RFC5746. Some renegotiating | |
4246 | TLS clients will continue a connection gracefully when they receive | |
4247 | the alert. Unfortunately OpenSSL mishandled this alert and would hang | |
4248 | waiting for a server hello which it will never receive. Now we treat a | |
4249 | received no_renegotiation alert as a fatal error. This is because | |
4250 | applications requesting a renegotiation might well expect it to succeed | |
4251 | and would have no code in place to handle the server denying it so the | |
4252 | only safe thing to do is to terminate the connection. | |
4253 | [Steve Henson] | |
4254 | ||
4255 | *) Add ctrl macro SSL_get_secure_renegotiation_support() which returns 1 if | |
4256 | peer supports secure renegotiation and 0 otherwise. Print out peer | |
4257 | renegotiation support in s_client/s_server. | |
4258 | [Steve Henson] | |
4259 | ||
4260 | *) Replace the highly broken and deprecated SPKAC certification method with | |
4261 | the updated NID creation version. This should correctly handle UTF8. | |
4262 | [Steve Henson] | |
4263 | ||
4264 | *) Implement RFC5746. Re-enable renegotiation but require the extension | |
4265 | as needed. Unfortunately, SSL3_FLAGS_ALLOW_UNSAFE_LEGACY_RENEGOTIATION | |
4266 | turns out to be a bad idea. It has been replaced by | |
4267 | SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION which can be set with | |
4268 | SSL_CTX_set_options(). This is really not recommended unless you | |
4269 | know what you are doing. | |
4270 | [Eric Rescorla <ekr@networkresonance.com>, Ben Laurie, Steve Henson] | |
4271 | ||
4272 | *) Fixes to stateless session resumption handling. Use initial_ctx when | |
4273 | issuing and attempting to decrypt tickets in case it has changed during | |
4274 | servername handling. Use a non-zero length session ID when attempting | |
4275 | stateless session resumption: this makes it possible to determine if | |
4276 | a resumption has occurred immediately after receiving server hello | |
4277 | (several places in OpenSSL subtly assume this) instead of later in | |
4278 | the handshake. | |
4279 | [Steve Henson] | |
4280 | ||
4281 | *) The functions ENGINE_ctrl(), OPENSSL_isservice(), | |
4282 | CMS_get1_RecipientRequest() and RAND_bytes() can return <=0 on error | |
4283 | fixes for a few places where the return code is not checked | |
4284 | correctly. | |
4285 | [Julia Lawall <julia@diku.dk>] | |
4286 | ||
4287 | *) Add --strict-warnings option to Configure script to include devteam | |
4288 | warnings in other configurations. | |
4289 | [Steve Henson] | |
4290 | ||
4291 | *) Add support for --libdir option and LIBDIR variable in makefiles. This | |
4292 | makes it possible to install openssl libraries in locations which | |
4293 | have names other than "lib", for example "/usr/lib64" which some | |
4294 | systems need. | |
4295 | [Steve Henson, based on patch from Jeremy Utley] | |
4296 | ||
4297 | *) Don't allow the use of leading 0x80 in OIDs. This is a violation of | |
4298 | X690 8.9.12 and can produce some misleading textual output of OIDs. | |
4299 | [Steve Henson, reported by Dan Kaminsky] | |
4300 | ||
4301 | *) Delete MD2 from algorithm tables. This follows the recommendation in | |
4302 | several standards that it is not used in new applications due to | |
4303 | several cryptographic weaknesses. For binary compatibility reasons | |
4304 | the MD2 API is still compiled in by default. | |
4305 | [Steve Henson] | |
4306 | ||
4307 | *) Add compression id to {d2i,i2d}_SSL_SESSION so it is correctly saved | |
4308 | and restored. | |
4309 | [Steve Henson] | |
4310 | ||
4311 | *) Rename uni2asc and asc2uni functions to OPENSSL_uni2asc and | |
4312 | OPENSSL_asc2uni conditionally on Netware platforms to avoid a name | |
4313 | clash. | |
4314 | [Guenter <lists@gknw.net>] | |
4315 | ||
4316 | *) Fix the server certificate chain building code to use X509_verify_cert(), | |
4317 | it used to have an ad-hoc builder which was unable to cope with anything | |
4318 | other than a simple chain. | |
4319 | [David Woodhouse <dwmw2@infradead.org>, Steve Henson] | |
4320 | ||
4321 | *) Don't check self signed certificate signatures in X509_verify_cert() | |
4322 | by default (a flag can override this): it just wastes time without | |
4323 | adding any security. As a useful side effect self signed root CAs | |
4324 | with non-FIPS digests are now usable in FIPS mode. | |
4325 | [Steve Henson] | |
4326 | ||
4327 | *) In dtls1_process_out_of_seq_message() the check if the current message | |
4328 | is already buffered was missing. For every new message was memory | |
4329 | allocated, allowing an attacker to perform an denial of service attack | |
4330 | with sending out of seq handshake messages until there is no memory | |
4331 | left. Additionally every future message was buffered, even if the | |
4332 | sequence number made no sense and would be part of another handshake. | |
4333 | So only messages with sequence numbers less than 10 in advance will be | |
4334 | buffered. (CVE-2009-1378) | |
4335 | [Robin Seggelmann, discovered by Daniel Mentz] | |
4336 | ||
4337 | *) Records are buffered if they arrive with a future epoch to be | |
4338 | processed after finishing the corresponding handshake. There is | |
4339 | currently no limitation to this buffer allowing an attacker to perform | |
4340 | a DOS attack with sending records with future epochs until there is no | |
4341 | memory left. This patch adds the pqueue_size() function to determine | |
4342 | the size of a buffer and limits the record buffer to 100 entries. | |
4343 | (CVE-2009-1377) | |
4344 | [Robin Seggelmann, discovered by Daniel Mentz] | |
4345 | ||
4346 | *) Keep a copy of frag->msg_header.frag_len so it can be used after the | |
4347 | parent structure is freed. (CVE-2009-1379) | |
4348 | [Daniel Mentz] | |
4349 | ||
4350 | *) Handle non-blocking I/O properly in SSL_shutdown() call. | |
4351 | [Darryl Miles <darryl-mailinglists@netbauds.net>] | |
4352 | ||
4353 | *) Add 2.5.4.* OIDs | |
4354 | [Ilya O. <vrghost@gmail.com>] | |
4355 | ||
4356 | Changes between 0.9.8k and 0.9.8l [5 Nov 2009] | |
4357 | ||
4358 | *) Disable renegotiation completely - this fixes a severe security | |
4359 | problem (CVE-2009-3555) at the cost of breaking all | |
4360 | renegotiation. Renegotiation can be re-enabled by setting | |
4361 | SSL3_FLAGS_ALLOW_UNSAFE_LEGACY_RENEGOTIATION in s3->flags at | |
4362 | run-time. This is really not recommended unless you know what | |
4363 | you're doing. | |
4364 | [Ben Laurie] | |
4365 | ||
4366 | Changes between 0.9.8j and 0.9.8k [25 Mar 2009] | |
4367 | ||
4368 | *) Don't set val to NULL when freeing up structures, it is freed up by | |
4369 | underlying code. If sizeof(void *) > sizeof(long) this can result in | |
4370 | zeroing past the valid field. (CVE-2009-0789) | |
4371 | [Paolo Ganci <Paolo.Ganci@AdNovum.CH>] | |
4372 | ||
4373 | *) Fix bug where return value of CMS_SignerInfo_verify_content() was not | |
4374 | checked correctly. This would allow some invalid signed attributes to | |
4375 | appear to verify correctly. (CVE-2009-0591) | |
4376 | [Ivan Nestlerode <inestlerode@us.ibm.com>] | |
4377 | ||
4378 | *) Reject UniversalString and BMPString types with invalid lengths. This | |
4379 | prevents a crash in ASN1_STRING_print_ex() which assumes the strings have | |
4380 | a legal length. (CVE-2009-0590) | |
4381 | [Steve Henson] | |
4382 | ||
4383 | *) Set S/MIME signing as the default purpose rather than setting it | |
4384 | unconditionally. This allows applications to override it at the store | |
4385 | level. | |
4386 | [Steve Henson] | |
4387 | ||
4388 | *) Permit restricted recursion of ASN1 strings. This is needed in practice | |
4389 | to handle some structures. | |
4390 | [Steve Henson] | |
4391 | ||
4392 | *) Improve efficiency of mem_gets: don't search whole buffer each time | |
4393 | for a '\n' | |
4394 | [Jeremy Shapiro <jnshapir@us.ibm.com>] | |
4395 | ||
4396 | *) New -hex option for openssl rand. | |
4397 | [Matthieu Herrb] | |
4398 | ||
4399 | *) Print out UTF8String and NumericString when parsing ASN1. | |
4400 | [Steve Henson] | |
4401 | ||
4402 | *) Support NumericString type for name components. | |
4403 | [Steve Henson] | |
4404 | ||
4405 | *) Allow CC in the environment to override the automatically chosen | |
4406 | compiler. Note that nothing is done to ensure flags work with the | |
4407 | chosen compiler. | |
4408 | [Ben Laurie] | |
4409 | ||
4410 | Changes between 0.9.8i and 0.9.8j [07 Jan 2009] | |
4411 | ||
4412 | *) Properly check EVP_VerifyFinal() and similar return values | |
4413 | (CVE-2008-5077). | |
4414 | [Ben Laurie, Bodo Moeller, Google Security Team] | |
4415 | ||
4416 | *) Enable TLS extensions by default. | |
4417 | [Ben Laurie] | |
4418 | ||
4419 | *) Allow the CHIL engine to be loaded, whether the application is | |
4420 | multithreaded or not. (This does not release the developer from the | |
4421 | obligation to set up the dynamic locking callbacks.) | |
4422 | [Sander Temme <sander@temme.net>] | |
4423 | ||
4424 | *) Use correct exit code if there is an error in dgst command. | |
4425 | [Steve Henson; problem pointed out by Roland Dirlewanger] | |
4426 | ||
4427 | *) Tweak Configure so that you need to say "experimental-jpake" to enable | |
4428 | JPAKE, and need to use -DOPENSSL_EXPERIMENTAL_JPAKE in applications. | |
4429 | [Bodo Moeller] | |
4430 | ||
4431 | *) Add experimental JPAKE support, including demo authentication in | |
4432 | s_client and s_server. | |
4433 | [Ben Laurie] | |
4434 | ||
4435 | *) Set the comparison function in v3_addr_canonize(). | |
4436 | [Rob Austein <sra@hactrn.net>] | |
4437 | ||
4438 | *) Add support for XMPP STARTTLS in s_client. | |
4439 | [Philip Paeps <philip@freebsd.org>] | |
4440 | ||
4441 | *) Change the server-side SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG behavior | |
4442 | to ensure that even with this option, only ciphersuites in the | |
4443 | server's preference list will be accepted. (Note that the option | |
4444 | applies only when resuming a session, so the earlier behavior was | |
4445 | just about the algorithm choice for symmetric cryptography.) | |
4446 | [Bodo Moeller] | |
4447 | ||
4448 | Changes between 0.9.8h and 0.9.8i [15 Sep 2008] | |
4449 | ||
4450 | *) Fix NULL pointer dereference if a DTLS server received | |
4451 | ChangeCipherSpec as first record (CVE-2009-1386). | |
4452 | [PR #1679] | |
4453 | ||
4454 | *) Fix a state transition in s3_srvr.c and d1_srvr.c | |
4455 | (was using SSL3_ST_CW_CLNT_HELLO_B, should be ..._ST_SW_SRVR_...). | |
4456 | [Nagendra Modadugu] | |
4457 | ||
4458 | *) The fix in 0.9.8c that supposedly got rid of unsafe | |
4459 | double-checked locking was incomplete for RSA blinding, | |
4460 | addressing just one layer of what turns out to have been | |
4461 | doubly unsafe triple-checked locking. | |
4462 | ||
4463 | So now fix this for real by retiring the MONT_HELPER macro | |
4464 | in crypto/rsa/rsa_eay.c. | |
4465 | ||
4466 | [Bodo Moeller; problem pointed out by Marius Schilder] | |
4467 | ||
4468 | *) Various precautionary measures: | |
4469 | ||
4470 | - Avoid size_t integer overflow in HASH_UPDATE (md32_common.h). | |
4471 | ||
4472 | - Avoid a buffer overflow in d2i_SSL_SESSION() (ssl_asn1.c). | |
4473 | (NB: This would require knowledge of the secret session ticket key | |
4474 | to exploit, in which case you'd be SOL either way.) | |
4475 | ||
4476 | - Change bn_nist.c so that it will properly handle input BIGNUMs | |
4477 | outside the expected range. | |
4478 | ||
4479 | - Enforce the 'num' check in BN_div() (bn_div.c) for non-BN_DEBUG | |
4480 | builds. | |
4481 | ||
4482 | [Neel Mehta, Bodo Moeller] | |
4483 | ||
4484 | *) Allow engines to be "soft loaded" - i.e. optionally don't die if | |
4485 | the load fails. Useful for distros. | |
4486 | [Ben Laurie and the FreeBSD team] | |
4487 | ||
4488 | *) Add support for Local Machine Keyset attribute in PKCS#12 files. | |
4489 | [Steve Henson] | |
4490 | ||
4491 | *) Fix BN_GF2m_mod_arr() top-bit cleanup code. | |
4492 | [Huang Ying] | |
4493 | ||
4494 | *) Expand ENGINE to support engine supplied SSL client certificate functions. | |
4495 | ||
4496 | This work was sponsored by Logica. | |
4497 | [Steve Henson] | |
4498 | ||
4499 | *) Add CryptoAPI ENGINE to support use of RSA and DSA keys held in Windows | |
4500 | keystores. Support for SSL/TLS client authentication too. | |
4501 | Not compiled unless enable-capieng specified to Configure. | |
4502 | ||
4503 | This work was sponsored by Logica. | |
4504 | [Steve Henson] | |
4505 | ||
4506 | *) Fix bug in X509_ATTRIBUTE creation: don't set attribute using | |
4507 | ASN1_TYPE_set1 if MBSTRING flag set. This bug would crash certain | |
4508 | attribute creation routines such as certificate requests and PKCS#12 | |
4509 | files. | |
4510 | [Steve Henson] | |
4511 | ||
4512 | Changes between 0.9.8g and 0.9.8h [28 May 2008] | |
4513 | ||
4514 | *) Fix flaw if 'Server Key exchange message' is omitted from a TLS | |
4515 | handshake which could lead to a client crash as found using the | |
4516 | Codenomicon TLS test suite (CVE-2008-1672) | |
4517 | [Steve Henson, Mark Cox] | |
4518 | ||
4519 | *) Fix double free in TLS server name extensions which could lead to | |
4520 | a remote crash found by Codenomicon TLS test suite (CVE-2008-0891) | |
4521 | [Joe Orton] | |
4522 | ||
4523 | *) Clear error queue in SSL_CTX_use_certificate_chain_file() | |
4524 | ||
4525 | Clear the error queue to ensure that error entries left from | |
4526 | older function calls do not interfere with the correct operation. | |
4527 | [Lutz Jaenicke, Erik de Castro Lopo] | |
4528 | ||
4529 | *) Remove root CA certificates of commercial CAs: | |
4530 | ||
4531 | The OpenSSL project does not recommend any specific CA and does not | |
4532 | have any policy with respect to including or excluding any CA. | |
4533 | Therefore it does not make any sense to ship an arbitrary selection | |
4534 | of root CA certificates with the OpenSSL software. | |
4535 | [Lutz Jaenicke] | |
4536 | ||
4537 | *) RSA OAEP patches to fix two separate invalid memory reads. | |
4538 | The first one involves inputs when 'lzero' is greater than | |
4539 | 'SHA_DIGEST_LENGTH' (it would read about SHA_DIGEST_LENGTH bytes | |
4540 | before the beginning of from). The second one involves inputs where | |
4541 | the 'db' section contains nothing but zeroes (there is a one-byte | |
4542 | invalid read after the end of 'db'). | |
4543 | [Ivan Nestlerode <inestlerode@us.ibm.com>] | |
4544 | ||
4545 | *) Partial backport from 0.9.9-dev: | |
4546 | ||
4547 | Introduce bn_mul_mont (dedicated Montgomery multiplication | |
4548 | procedure) as a candidate for BIGNUM assembler implementation. | |
4549 | While 0.9.9-dev uses assembler for various architectures, only | |
4550 | x86_64 is available by default here in the 0.9.8 branch, and | |
4551 | 32-bit x86 is available through a compile-time setting. | |
4552 | ||
4553 | To try the 32-bit x86 assembler implementation, use Configure | |
4554 | option "enable-montasm" (which exists only for this backport). | |
4555 | ||
4556 | As "enable-montasm" for 32-bit x86 disclaims code stability | |
4557 | anyway, in this constellation we activate additional code | |
4558 | backported from 0.9.9-dev for further performance improvements, | |
4559 | namely BN_from_montgomery_word. (To enable this otherwise, | |
4560 | e.g. x86_64, try "-DMONT_FROM_WORD___NON_DEFAULT_0_9_8_BUILD".) | |
4561 | ||
4562 | [Andy Polyakov (backport partially by Bodo Moeller)] | |
4563 | ||
4564 | *) Add TLS session ticket callback. This allows an application to set | |
4565 | TLS ticket cipher and HMAC keys rather than relying on hardcoded fixed | |
4566 | values. This is useful for key rollover for example where several key | |
4567 | sets may exist with different names. | |
4568 | [Steve Henson] | |
4569 | ||
4570 | *) Reverse ENGINE-internal logic for caching default ENGINE handles. | |
4571 | This was broken until now in 0.9.8 releases, such that the only way | |
4572 | a registered ENGINE could be used (assuming it initialises | |
4573 | successfully on the host) was to explicitly set it as the default | |
4574 | for the relevant algorithms. This is in contradiction with 0.9.7 | |
4575 | behaviour and the documentation. With this fix, when an ENGINE is | |
4576 | registered into a given algorithm's table of implementations, the | |
4577 | 'uptodate' flag is reset so that auto-discovery will be used next | |
4578 | time a new context for that algorithm attempts to select an | |
4579 | implementation. | |
4580 | [Ian Lister (tweaked by Geoff Thorpe)] | |
4581 | ||
4582 | *) Backport of CMS code to OpenSSL 0.9.8. This differs from the 0.9.9 | |
4583 | implementation in the following ways: | |
4584 | ||
4585 | Lack of EVP_PKEY_ASN1_METHOD means algorithm parameters have to be | |
4586 | hard coded. | |
4587 | ||
4588 | Lack of BER streaming support means one pass streaming processing is | |
4589 | only supported if data is detached: setting the streaming flag is | |
4590 | ignored for embedded content. | |
4591 | ||
4592 | CMS support is disabled by default and must be explicitly enabled | |
4593 | with the enable-cms configuration option. | |
4594 | [Steve Henson] | |
4595 | ||
4596 | *) Update the GMP engine glue to do direct copies between BIGNUM and | |
4597 | mpz_t when openssl and GMP use the same limb size. Otherwise the | |
4598 | existing "conversion via a text string export" trick is still used. | |
4599 | [Paul Sheer <paulsheer@gmail.com>] | |
4600 | ||
4601 | *) Zlib compression BIO. This is a filter BIO which compressed and | |
4602 | uncompresses any data passed through it. | |
4603 | [Steve Henson] | |
4604 | ||
4605 | *) Add AES_wrap_key() and AES_unwrap_key() functions to implement | |
4606 | RFC3394 compatible AES key wrapping. | |
4607 | [Steve Henson] | |
4608 | ||
4609 | *) Add utility functions to handle ASN1 structures. ASN1_STRING_set0(): | |
4610 | sets string data without copying. X509_ALGOR_set0() and | |
4611 | X509_ALGOR_get0(): set and retrieve X509_ALGOR (AlgorithmIdentifier) | |
4612 | data. Attribute function X509at_get0_data_by_OBJ(): retrieves data | |
4613 | from an X509_ATTRIBUTE structure optionally checking it occurs only | |
4614 | once. ASN1_TYPE_set1(): set and ASN1_TYPE structure copying supplied | |
4615 | data. | |
4616 | [Steve Henson] | |
4617 | ||
4618 | *) Fix BN flag handling in RSA_eay_mod_exp() and BN_MONT_CTX_set() | |
4619 | to get the expected BN_FLG_CONSTTIME behavior. | |
4620 | [Bodo Moeller (Google)] | |
4621 | ||
4622 | *) Netware support: | |
4623 | ||
4624 | - fixed wrong usage of ioctlsocket() when build for LIBC BSD sockets | |
4625 | - fixed do_tests.pl to run the test suite with CLIB builds too (CLIB_OPT) | |
4626 | - added some more tests to do_tests.pl | |
4627 | - fixed RunningProcess usage so that it works with newer LIBC NDKs too | |
4628 | - removed usage of BN_LLONG for CLIB builds to avoid runtime dependency | |
4629 | - added new Configure targets netware-clib-bsdsock, netware-clib-gcc, | |
4630 | netware-clib-bsdsock-gcc, netware-libc-bsdsock-gcc | |
4631 | - various changes to netware.pl to enable gcc-cross builds on Win32 | |
4632 | platform | |
4633 | - changed crypto/bio/b_sock.c to work with macro functions (CLIB BSD) | |
4634 | - various changes to fix missing prototype warnings | |
4635 | - fixed x86nasm.pl to create correct asm files for NASM COFF output | |
4636 | - added AES, WHIRLPOOL and CPUID assembler code to build files | |
4637 | - added missing AES assembler make rules to mk1mf.pl | |
4638 | - fixed order of includes in apps/ocsp.c so that e_os.h settings apply | |

4640 | ||
4641 | *) Implement certificate status request TLS extension defined in RFC3546. | |
4642 | A client can set the appropriate parameters and receive the encoded | |
4643 | OCSP response via a callback. A server can query the supplied parameters | |
4644 | and set the encoded OCSP response in the callback. Add simplified examples | |
4645 | to s_client and s_server. | |

4648 | Changes between 0.9.8f and 0.9.8g [19 Oct 2007] | |
4649 | ||
4650 | *) Fix various bugs: | |
4651 | + Binary incompatibility of ssl_ctx_st structure | |
4652 | + DTLS interoperation with non-compliant servers | |
4653 | + Don't call get_session_cb() without proposed session | |
4654 | + Fix ia64 assembler code | |
4655 | [Andy Polyakov, Steve Henson] | |
4656 | ||
4657 | Changes between 0.9.8e and 0.9.8f [11 Oct 2007] | |
4658 | ||
4659 | *) DTLS Handshake overhaul. There were longstanding issues with | |
4660 | OpenSSL DTLS implementation, which were making it impossible for | |
4661 | RFC 4347 compliant client to communicate with OpenSSL server. | |
4662 | Unfortunately just fixing these incompatibilities would "cut off" | |
4663 | pre-0.9.8f clients. To allow for hassle free upgrade post-0.9.8e | |
4664 | server keeps tolerating non RFC compliant syntax. The opposite is | |
4665 | not true, 0.9.8f client can not communicate with earlier server. | |
4666 | This update even addresses CVE-2007-4995. | |
4667 | [Andy Polyakov] | |
4668 | ||
4669 | *) Changes to avoid need for function casts in OpenSSL: some compilers | |
4670 | (gcc 4.2 and later) reject their use. | |
4671 | [Kurt Roeckx <kurt@roeckx.be>, Peter Hartley <pdh@utter.chaos.org.uk>, | |
4672 | Steve Henson] | |
4673 | ||
4674 | *) Add RFC4507 support to OpenSSL. This includes the corrections in | |
4675 | RFC4507bis. The encrypted ticket format is an encrypted encoded | |
4676 | SSL_SESSION structure, that way new session features are automatically | |
4677 | supported. | |
4678 | ||
4679 | If a client application caches session in an SSL_SESSION structure | |
4680 | support is transparent because tickets are now stored in the encoded | |
4681 | SSL_SESSION. | |
4682 | ||
4683 | The SSL_CTX structure automatically generates keys for ticket | |
4684 | protection in servers so again support should be possible | |
4685 | with no application modification. | |
4686 | ||
4687 | If a client or server wishes to disable RFC4507 support then the option | |
4688 | SSL_OP_NO_TICKET can be set. | |
4689 | ||
4690 | Add a TLS extension debugging callback to allow the contents of any client | |
4691 | or server extensions to be examined. | |
4692 | ||
4693 | This work was sponsored by Google. | |
4694 | [Steve Henson] | |
4695 | ||
4696 | *) Add initial support for TLS extensions, specifically for the server_name | |
4697 | extension so far. The SSL_SESSION, SSL_CTX, and SSL data structures now | |
4698 | have new members for a host name. The SSL data structure has an | |
4699 | additional member SSL_CTX *initial_ctx so that new sessions can be | |
4700 | stored in that context to allow for session resumption, even after the | |
4701 | SSL has been switched to a new SSL_CTX in reaction to a client's | |
4702 | server_name extension. | |
4703 | ||
4704 | New functions (subject to change): | |
4705 | ||
4706 | SSL_get_servername() | |
4707 | SSL_get_servername_type() | |
4708 | SSL_set_SSL_CTX() | |
4709 | ||
4710 | New CTRL codes and macros (subject to change): | |
4711 | ||
4712 | SSL_CTRL_SET_TLSEXT_SERVERNAME_CB | |
4713 | - SSL_CTX_set_tlsext_servername_callback() | |
4714 | SSL_CTRL_SET_TLSEXT_SERVERNAME_ARG | |
4715 | - SSL_CTX_set_tlsext_servername_arg() | |
4716 | SSL_CTRL_SET_TLSEXT_HOSTNAME - SSL_set_tlsext_host_name() | |
4717 | ||
4718 | openssl s_client has a new '-servername ...' option. | |
4719 | ||
4720 | openssl s_server has new options '-servername_host ...', '-cert2 ...', | |
4721 | '-key2 ...', '-servername_fatal' (subject to change). This allows | |
4722 | testing the HostName extension for a specific single host name ('-cert' | |
4723 | and '-key' remain fallbacks for handshakes without HostName | |
4724 | negotiation). If the unrecognized_name alert has to be sent, this by | |
4725 | default is a warning; it becomes fatal with the '-servername_fatal' | |
4726 | option. | |
4727 | ||
4728 | [Peter Sylvester, Remy Allais, Christophe Renou, Steve Henson] | |
4729 | ||
4730 | *) Add AES and SSE2 assembly language support to VC++ build. | |
4731 | [Steve Henson] | |
4732 | ||
4733 | *) Mitigate attack on final subtraction in Montgomery reduction. | |
4734 | [Andy Polyakov] | |
4735 | ||
4736 | *) Fix crypto/ec/ec_mult.c to work properly with scalars of value 0 | |
4737 | (which previously caused an internal error). | |
4738 | [Bodo Moeller] | |
4739 | ||
4740 | *) Squeeze another 10% out of IGE mode when in != out. | |
4741 | [Ben Laurie] | |
4742 | ||
4743 | *) AES IGE mode speedup. | |
4744 | [Dean Gaudet (Google)] | |
4745 | ||
4746 | *) Add the Korean symmetric 128-bit cipher SEED (see | |
4747 | http://www.kisa.or.kr/kisa/seed/jsp/seed_eng.jsp) and | |
4748 | add SEED ciphersuites from RFC 4162: | |
4749 | ||
4750 | TLS_RSA_WITH_SEED_CBC_SHA = "SEED-SHA" | |
4751 | TLS_DHE_DSS_WITH_SEED_CBC_SHA = "DHE-DSS-SEED-SHA" | |
4752 | TLS_DHE_RSA_WITH_SEED_CBC_SHA = "DHE-RSA-SEED-SHA" | |
4753 | TLS_DH_anon_WITH_SEED_CBC_SHA = "ADH-SEED-SHA" | |
4754 | ||
4755 | To minimize changes between patchlevels in the OpenSSL 0.9.8 | |
4756 | series, SEED remains excluded from compilation unless OpenSSL | |
4757 | is configured with 'enable-seed'. | |
4758 | [KISA, Bodo Moeller] | |
4759 | ||
4760 | *) Mitigate branch prediction attacks, which can be practical if a | |
4761 | single processor is shared, allowing a spy process to extract | |
4762 | information. For detailed background information, see | |
4763 | http://eprint.iacr.org/2007/039 (O. Aciicmez, S. Gueron, | |
4764 | J.-P. Seifert, "New Branch Prediction Vulnerabilities in OpenSSL | |
4765 | and Necessary Software Countermeasures"). The core of the change | |
4766 | are new versions BN_div_no_branch() and | |
4767 | BN_mod_inverse_no_branch() of BN_div() and BN_mod_inverse(), | |
4768 | respectively, which are slower, but avoid the security-relevant | |
4769 | conditional branches. These are automatically called by BN_div() | |
4770 | and BN_mod_inverse() if the flag BN_FLG_CONSTTIME is set for one | |
4771 | of the input BIGNUMs. Also, BN_is_bit_set() has been changed to | |
4772 | remove a conditional branch. | |
4773 | ||
4774 | BN_FLG_CONSTTIME is the new name for the previous | |
4775 | BN_FLG_EXP_CONSTTIME flag, since it now affects more than just | |
4776 | modular exponentiation. (Since OpenSSL 0.9.7h, setting this flag | |
4777 | in the exponent causes BN_mod_exp_mont() to use the alternative | |
4778 | implementation in BN_mod_exp_mont_consttime().) The old name | |
4779 | remains as a deprecated alias. | |
4780 | ||
4781 | Similarly, RSA_FLAG_NO_EXP_CONSTTIME is replaced by a more general | |
4782 | RSA_FLAG_NO_CONSTTIME flag since the RSA implementation now uses | |
4783 | constant-time implementations for more than just exponentiation. | |
4784 | Here too the old name is kept as a deprecated alias. | |
4785 | ||
4786 | BN_BLINDING_new() will now use BN_dup() for the modulus so that | |
4787 | the BN_BLINDING structure gets an independent copy of the | |
4788 | modulus. This means that the previous "BIGNUM *m" argument to | |
4789 | BN_BLINDING_new() and to BN_BLINDING_create_param() now | |
4790 | essentially becomes "const BIGNUM *m", although we can't actually | |
4791 | change this in the header file before 0.9.9. It allows | |
4792 | RSA_setup_blinding() to use BN_with_flags() on the modulus to | |
4793 | enable BN_FLG_CONSTTIME. | |
4794 | ||
4795 | [Matthew D Wood (Intel Corp)] | |
4796 | ||
4797 | *) In the SSL/TLS server implementation, be strict about session ID | |
4798 | context matching (which matters if an application uses a single | |
4799 | external cache for different purposes). Previously, | |
4800 | out-of-context reuse was forbidden only if SSL_VERIFY_PEER was | |
4801 | set. This did ensure strict client verification, but meant that, | |
4802 | with applications using a single external cache for quite | |
4803 | different requirements, clients could circumvent ciphersuite | |
4804 | restrictions for a given session ID context by starting a session | |
4805 | in a different context. | |
4806 | [Bodo Moeller] | |
4807 | ||
4808 | *) Include "!eNULL" in SSL_DEFAULT_CIPHER_LIST to make sure that | |
4809 | a ciphersuite string such as "DEFAULT:RSA" cannot enable | |
4810 | authentication-only ciphersuites. | |
4811 | [Bodo Moeller] | |
4812 | ||
4813 | *) Update the SSL_get_shared_ciphers() fix CVE-2006-3738 which was | |
4814 | not complete and could lead to a possible single byte overflow | |
4815 | (CVE-2007-5135) [Ben Laurie] | |
4816 | ||
4817 | Changes between 0.9.8d and 0.9.8e [23 Feb 2007] | |
4818 | ||
4819 | *) Since AES128 and AES256 (and similarly Camellia128 and | |
4820 | Camellia256) share a single mask bit in the logic of | |
4821 | ssl/ssl_ciph.c, the code for masking out disabled ciphers needs a | |
4822 | kludge to work properly if AES128 is available and AES256 isn't | |
4823 | (or if Camellia128 is available and Camellia256 isn't). | |
4824 | [Victor Duchovni] | |
4825 | ||
4826 | *) Fix the BIT STRING encoding generated by crypto/ec/ec_asn1.c | |
4827 | (within i2d_ECPrivateKey, i2d_ECPKParameters, i2d_ECParameters): | |
4828 | When a point or a seed is encoded in a BIT STRING, we need to | |
4829 | prevent the removal of trailing zero bits to get the proper DER | |
4830 | encoding. (By default, crypto/asn1/a_bitstr.c assumes the case | |
4831 | of a NamedBitList, for which trailing 0 bits need to be removed.) | |
4832 | [Bodo Moeller] | |
4833 | ||
4834 | *) Have SSL/TLS server implementation tolerate "mismatched" record | |
4835 | protocol version while receiving ClientHello even if the | |
4836 | ClientHello is fragmented. (The server can't insist on the | |
4837 | particular protocol version it has chosen before the ServerHello | |
4838 | message has informed the client about his choice.) | |
4839 | [Bodo Moeller] | |
4840 | ||
4841 | *) Add RFC 3779 support. | |
4842 | [Rob Austein for ARIN, Ben Laurie] | |
4843 | ||
4844 | *) Load error codes if they are not already present instead of using a | |
4845 | static variable. This allows them to be cleanly unloaded and reloaded. | |
4846 | Improve header file function name parsing. | |
4847 | [Steve Henson] | |
4848 | ||
4849 | *) extend SMTP and IMAP protocol emulation in s_client to use EHLO | |
4850 | or CAPABILITY handshake as required by RFCs. | |
4851 | [Goetz Babin-Ebell] | |
4852 | ||
4853 | Changes between 0.9.8c and 0.9.8d [28 Sep 2006] | |
4854 | ||
4855 | *) Introduce limits to prevent malicious keys being able to | |
4856 | cause a denial of service. (CVE-2006-2940) | |
4857 | [Steve Henson, Bodo Moeller] | |
4858 | ||
4859 | *) Fix ASN.1 parsing of certain invalid structures that can result | |
4860 | in a denial of service. (CVE-2006-2937) [Steve Henson] | |
4861 | ||
4862 | *) Fix buffer overflow in SSL_get_shared_ciphers() function. | |
4863 | (CVE-2006-3738) [Tavis Ormandy and Will Drewry, Google Security Team] | |
4864 | ||
4865 | *) Fix SSL client code which could crash if connecting to a | |
4866 | malicious SSLv2 server. (CVE-2006-4343) | |
4867 | [Tavis Ormandy and Will Drewry, Google Security Team] | |
4868 | ||
4869 | *) Since 0.9.8b, ciphersuite strings naming explicit ciphersuites | |
4870 | match only those. Before that, "AES256-SHA" would be interpreted | |
4871 | as a pattern and match "AES128-SHA" too (since AES128-SHA got | |
4872 | the same strength classification in 0.9.7h) as we currently only | |
4873 | have a single AES bit in the ciphersuite description bitmap. | |
4874 | That change, however, also applied to ciphersuite strings such as | |
4875 | "RC4-MD5" that intentionally matched multiple ciphersuites -- | |
4876 | namely, SSL 2.0 ciphersuites in addition to the more common ones | |
4877 | from SSL 3.0/TLS 1.0. | |
4878 | ||
4879 | So we change the selection algorithm again: Naming an explicit | |
4880 | ciphersuite selects this one ciphersuite, and any other similar | |
4881 | ciphersuite (same bitmap) from *other* protocol versions. | |
4882 | Thus, "RC4-MD5" again will properly select both the SSL 2.0 | |
4883 | ciphersuite and the SSL 3.0/TLS 1.0 ciphersuite. | |
4884 | ||
4885 | Since SSL 2.0 does not have any ciphersuites for which the | |
4886 | 128/256 bit distinction would be relevant, this works for now. | |
4887 | The proper fix will be to use different bits for AES128 and | |
4888 | AES256, which would have avoided the problems from the beginning; | |
4889 | however, bits are scarce, so we can only do this in a new release | |
4890 | (not just a patchlevel) when we can change the SSL_CIPHER | |
4891 | definition to split the single 'unsigned long mask' bitmap into | |
4892 | multiple values to extend the available space. | |
4893 | ||
4894 | [Bodo Moeller] | |
4895 | ||
4896 | Changes between 0.9.8b and 0.9.8c [05 Sep 2006] | |
4897 | ||
4898 | *) Avoid PKCS #1 v1.5 signature attack discovered by Daniel Bleichenbacher | |
4899 | (CVE-2006-4339) [Ben Laurie and Google Security Team] | |
4900 | ||
4901 | *) Add AES IGE and biIGE modes. | |
4902 | [Ben Laurie] | |
4903 | ||
4904 | *) Change the Unix randomness entropy gathering to use poll() when | |
4905 | possible instead of select(), since the latter has some | |
4906 | undesirable limitations. | |
4907 | [Darryl Miles via Richard Levitte and Bodo Moeller] | |
4908 | ||
4909 | *) Disable "ECCdraft" ciphersuites more thoroughly. Now special | |
4910 | treatment in ssl/ssl_ciph.s makes sure that these ciphersuites | |
4911 | cannot be implicitly activated as part of, e.g., the "AES" alias. | |
4912 | However, please upgrade to OpenSSL 0.9.9[-dev] for | |
4913 | non-experimental use of the ECC ciphersuites to get TLS extension | |
4914 | support, which is required for curve and point format negotiation | |
4915 | to avoid potential handshake problems. | |
4916 | [Bodo Moeller] | |
4917 | ||
4918 | *) Disable rogue ciphersuites: | |
4919 | ||
4920 | - SSLv2 0x08 0x00 0x80 ("RC4-64-MD5") | |
4921 | - SSLv3/TLSv1 0x00 0x61 ("EXP1024-RC2-CBC-MD5") | |
4922 | - SSLv3/TLSv1 0x00 0x60 ("EXP1024-RC4-MD5") | |
4923 | ||
4924 | The latter two were purportedly from | |
4925 | draft-ietf-tls-56-bit-ciphersuites-0[01].txt, but do not really | |
4926 | appear there. | |
4927 | ||
4928 | Also deactivate the remaining ciphersuites from | |
4929 | draft-ietf-tls-56-bit-ciphersuites-01.txt. These are just as | |
4930 | unofficial, and the ID has long expired. | |
4931 | [Bodo Moeller] | |
4932 | ||
4933 | *) Fix RSA blinding Heisenbug (problems sometimes occurred on | |
4934 | dual-core machines) and other potential thread-safety issues. | |
4935 | [Bodo Moeller] | |
4936 | ||
4937 | *) Add the symmetric cipher Camellia (128-bit, 192-bit, 256-bit key | |
4938 | versions), which is now available for royalty-free use | |
4939 | (see http://info.isl.ntt.co.jp/crypt/eng/info/chiteki.html). | |
4940 | Also, add Camellia TLS ciphersuites from RFC 4132. | |
4941 | ||
4942 | To minimize changes between patchlevels in the OpenSSL 0.9.8 | |
4943 | series, Camellia remains excluded from compilation unless OpenSSL | |
4944 | is configured with 'enable-camellia'. | |
4945 | [NTT] | |
4946 | ||
4947 | *) Disable the padding bug check when compression is in use. The padding | |
4948 | bug check assumes the first packet is of even length, this is not | |
4949 | necessarily true if compression is enabled and can result in false | |
4950 | positives causing handshake failure. The actual bug test is ancient | |
4951 | code so it is hoped that implementations will either have fixed it by | |
4952 | now or any which still have the bug do not support compression. | |
4953 | [Steve Henson] | |
4954 | ||
4955 | Changes between 0.9.8a and 0.9.8b [04 May 2006] | |
4956 | ||
4957 | *) When applying a cipher rule check to see if string match is an explicit | |
4958 | cipher suite and only match that one cipher suite if it is. | |
4959 | [Steve Henson] | |
4960 | ||
4961 | *) Link in manifests for VC++ if needed. | |
4962 | [Austin Ziegler <halostatue@gmail.com>] | |
4963 | ||
4964 | *) Update support for ECC-based TLS ciphersuites according to | |
4965 | draft-ietf-tls-ecc-12.txt with proposed changes (but without | |
4966 | TLS extensions, which are supported starting with the 0.9.9 | |
4967 | branch, not in the OpenSSL 0.9.8 branch). | |
4968 | [Douglas Stebila] | |
4969 | ||
4970 | *) New functions EVP_CIPHER_CTX_new() and EVP_CIPHER_CTX_free() to support | |
4971 | opaque EVP_CIPHER_CTX handling. | |
4972 | [Steve Henson] | |
4973 | ||
4974 | *) Fixes and enhancements to zlib compression code. We now only use | |
4975 | "zlib1.dll" and use the default __cdecl calling convention on Win32 | |
4976 | to conform with the standards mentioned here: | |
4977 | http://www.zlib.net/DLL_FAQ.txt | |
4978 | Static zlib linking now works on Windows and the new --with-zlib-include | |
4979 | --with-zlib-lib options to Configure can be used to supply the location | |
4980 | of the headers and library. Gracefully handle case where zlib library | |
4981 | can't be loaded. | |
4982 | [Steve Henson] | |
4983 | ||
4984 | *) Several fixes and enhancements to the OID generation code. The old code | |
4985 | sometimes allowed invalid OIDs (1.X for X >= 40 for example), couldn't | |
4986 | handle numbers larger than ULONG_MAX, truncated printing and had a | |
4987 | non standard OBJ_obj2txt() behaviour. | |
4988 | [Steve Henson] | |
4989 | ||
4990 | *) Add support for building of engines under engine/ as shared libraries | |
4991 | under VC++ build system. | |
4992 | [Steve Henson] | |
4993 | ||
4994 | *) Corrected the numerous bugs in the Win32 path splitter in DSO. | |
4995 | Hopefully, we will not see any false combination of paths any more. | |
4996 | [Richard Levitte] | |
4997 | ||
4998 | Changes between 0.9.8 and 0.9.8a [11 Oct 2005] | |
4999 | ||
5000 | *) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING | |
5001 | (part of SSL_OP_ALL). This option used to disable the | |
5002 | countermeasure against man-in-the-middle protocol-version | |
5003 | rollback in the SSL 2.0 server implementation, which is a bad | |
5004 | idea. (CVE-2005-2969) | |
5005 | ||
5006 | [Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center | |
5007 | for Information Security, National Institute of Advanced Industrial | |
5008 | Science and Technology [AIST], Japan)] | |
5009 | ||
5010 | *) Add two function to clear and return the verify parameter flags. | |
5011 | [Steve Henson] | |
5012 | ||
5013 | *) Keep cipherlists sorted in the source instead of sorting them at | |
5014 | runtime, thus removing the need for a lock. | |
5015 | [Nils Larsch] | |
5016 | ||
5017 | *) Avoid some small subgroup attacks in Diffie-Hellman. | |
5018 | [Nick Mathewson and Ben Laurie] | |
5019 | ||
5020 | *) Add functions for well-known primes. | |
5021 | [Nick Mathewson] | |
5022 | ||
5023 | *) Extended Windows CE support. | |
5024 | [Satoshi Nakamura and Andy Polyakov] | |
5025 | ||
5026 | *) Initialize SSL_METHOD structures at compile time instead of during | |
5027 | runtime, thus removing the need for a lock. | |
5028 | [Steve Henson] | |
5029 | ||
5030 | *) Make PKCS7_decrypt() work even if no certificate is supplied by | |
5031 | attempting to decrypt each encrypted key in turn. Add support to | |
5032 | smime utility. | |
5033 | [Steve Henson] | |
5034 | ||
5035 | Changes between 0.9.7h and 0.9.8 [05 Jul 2005] | |
5036 | ||
5037 | [NB: OpenSSL 0.9.7i and later 0.9.7 patch levels were released after | |
5038 | OpenSSL 0.9.8.] | |
5039 | ||
5040 | *) Add libcrypto.pc and libssl.pc for those who feel they need them. | |
5041 | [Richard Levitte] | |
5042 | ||
5043 | *) Change CA.sh and CA.pl so they don't bundle the CSR and the private | |
5044 | key into the same file any more. | |
5045 | [Richard Levitte] | |
5046 | ||
5047 | *) Add initial support for Win64, both IA64 and AMD64/x64 flavors. | |
5048 | [Andy Polyakov] | |
5049 | ||
5050 | *) Add -utf8 command line and config file option to 'ca'. | |
5051 | [Stefan <stf@udoma.org] | |
5052 | ||
5053 | *) Removed the macro des_crypt(), as it seems to conflict with some | |
5054 | libraries. Use DES_crypt(). | |
5055 | [Richard Levitte] | |
5056 | ||
5057 | *) Correct naming of the 'chil' and '4758cca' ENGINEs. This | |
5058 | involves renaming the source and generated shared-libs for | |
5059 | both. The engines will accept the corrected or legacy ids | |
5060 | ('ncipher' and '4758_cca' respectively) when binding. NB, | |
5061 | this only applies when building 'shared'. | |
5062 | [Corinna Vinschen <vinschen@redhat.com> and Geoff Thorpe] | |
5063 | ||
5064 | *) Add attribute functions to EVP_PKEY structure. Modify | |
5065 | PKCS12_create() to recognize a CSP name attribute and | |
5066 | use it. Make -CSP option work again in pkcs12 utility. | |
5067 | [Steve Henson] | |
5068 | ||
5069 | *) Add new functionality to the bn blinding code: | |
5070 | - automatic re-creation of the BN_BLINDING parameters after | |
5071 | a fixed number of uses (currently 32) | |
5072 | - add new function for parameter creation | |
5073 | - introduce flags to control the update behaviour of the | |
5074 | BN_BLINDING parameters | |
5075 | - hide BN_BLINDING structure | |
5076 | Add a second BN_BLINDING slot to the RSA structure to improve | |
5077 | performance when a single RSA object is shared among several | |
5078 | threads. | |
5079 | [Nils Larsch] | |
5080 | ||
5081 | *) Add support for DTLS. | |
5082 | [Nagendra Modadugu <nagendra@cs.stanford.edu> and Ben Laurie] | |
5083 | ||
5084 | *) Add support for DER encoded private keys (SSL_FILETYPE_ASN1) | |
5085 | to SSL_CTX_use_PrivateKey_file() and SSL_use_PrivateKey_file() | |
5086 | [Walter Goulet] | |
5087 | ||
5088 | *) Remove buggy and incomplete DH cert support from | |
5089 | ssl/ssl_rsa.c and ssl/s3_both.c | |
5090 | [Nils Larsch] | |
5091 | ||
5092 | *) Use SHA-1 instead of MD5 as the default digest algorithm for | |
5093 | the apps/openssl applications. | |
5094 | [Nils Larsch] | |
5095 | ||
5096 | *) Compile clean with "-Wall -Wmissing-prototypes | |
5097 | -Wstrict-prototypes -Wmissing-declarations -Werror". Currently | |
5098 | DEBUG_SAFESTACK must also be set. | |
5099 | [Ben Laurie] | |
5100 | ||
5101 | *) Change ./Configure so that certain algorithms can be disabled by default. | |
5102 | The new counterpiece to "no-xxx" is "enable-xxx". | |
5103 | ||
5104 | The patented RC5 and MDC2 algorithms will now be disabled unless | |
5105 | "enable-rc5" and "enable-mdc2", respectively, are specified. | |
5106 | ||
5107 | (IDEA remains enabled despite being patented. This is because IDEA | |
5108 | is frequently required for interoperability, and there is no license | |
5109 | fee for non-commercial use. As before, "no-idea" can be used to | |
5110 | avoid this algorithm.) | |
5111 | ||
5112 | [Bodo Moeller] | |
5113 | ||
5114 | *) Add processing of proxy certificates (see RFC 3820). This work was | |
5115 | sponsored by KTH (The Royal Institute of Technology in Stockholm) and | |
5116 | EGEE (Enabling Grids for E-science in Europe). | |
5117 | [Richard Levitte] | |
5118 | ||
5119 | *) RC4 performance overhaul on modern architectures/implementations, such | |
5120 | as Intel P4, IA-64 and AMD64. | |
5121 | [Andy Polyakov] | |
5122 | ||
5123 | *) New utility extract-section.pl. This can be used specify an alternative | |
5124 | section number in a pod file instead of having to treat each file as | |
5125 | a separate case in Makefile. This can be done by adding two lines to the | |
5126 | pod file: | |
5127 | ||
5128 | =for comment openssl_section:XXX | |
5129 | ||
5130 | The blank line is mandatory. | |
5131 | ||
5132 | [Steve Henson] | |
5133 | ||
5134 | *) New arguments -certform, -keyform and -pass for s_client and s_server | |
5135 | to allow alternative format key and certificate files and passphrase | |
5136 | sources. | |
5137 | [Steve Henson] | |
5138 | ||
5139 | *) New structure X509_VERIFY_PARAM which combines current verify parameters, | |
5140 | update associated structures and add various utility functions. | |
5141 | ||
5142 | Add new policy related verify parameters, include policy checking in | |
5143 | standard verify code. Enhance 'smime' application with extra parameters | |
5144 | to support policy checking and print out. | |
5145 | [Steve Henson] | |
5146 | ||
5147 | *) Add a new engine to support VIA PadLock ACE extensions in the VIA C3 | |
5148 | Nehemiah processors. These extensions support AES encryption in hardware | |
5149 | as well as RNG (though RNG support is currently disabled). | |
5150 | [Michal Ludvig <michal@logix.cz>, with help from Andy Polyakov] | |
5151 | ||
5152 | *) Deprecate BN_[get|set]_params() functions (they were ignored internally). | |
5153 | [Geoff Thorpe] | |
5154 | ||
5155 | *) New FIPS 180-2 algorithms, SHA-224/-256/-384/-512 are implemented. | |
5156 | [Andy Polyakov and a number of other people] | |
5157 | ||
5158 | *) Improved PowerPC platform support. Most notably BIGNUM assembler | |
5159 | implementation contributed by IBM. | |
5160 | [Suresh Chari, Peter Waltenberg, Andy Polyakov] | |
5161 | ||
5162 | *) The new 'RSA_generate_key_ex' function now takes a BIGNUM for the public | |
5163 | exponent rather than 'unsigned long'. There is a corresponding change to | |
5164 | the new 'rsa_keygen' element of the RSA_METHOD structure. | |
5165 | [Jelte Jansen, Geoff Thorpe] | |
5166 | ||
5167 | *) Functionality for creating the initial serial number file is now | |
5168 | moved from CA.pl to the 'ca' utility with a new option -create_serial. | |
5169 | ||
5170 | (Before OpenSSL 0.9.7e, CA.pl used to initialize the serial | |
5171 | number file to 1, which is bound to cause problems. To avoid | |
5172 | the problems while respecting compatibility between different 0.9.7 | |
5173 | patchlevels, 0.9.7e employed 'openssl x509 -next_serial' in | |
5174 | CA.pl for serial number initialization. With the new release 0.9.8, | |
5175 | we can fix the problem directly in the 'ca' utility.) | |
5176 | [Steve Henson] | |
5177 | ||
5178 | *) Reduced header interdependencies by declaring more opaque objects in | |
5179 | ossl_typ.h. As a consequence, including some headers (eg. engine.h) will | |
5180 | give fewer recursive includes, which could break lazy source code - so | |
5181 | this change is covered by the OPENSSL_NO_DEPRECATED symbol. As always, | |
5182 | developers should define this symbol when building and using openssl to | |
5183 | ensure they track the recommended behaviour, interfaces, [etc], but | |
5184 | backwards-compatible behaviour prevails when this isn't defined. | |
5185 | [Geoff Thorpe] | |
5186 | ||
5187 | *) New function X509_POLICY_NODE_print() which prints out policy nodes. | |
5188 | [Steve Henson] | |
5189 | ||
5190 | *) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality. | |
5191 | This will generate a random key of the appropriate length based on the | |
5192 | cipher context. The EVP_CIPHER can provide its own random key generation | |
5193 | routine to support keys of a specific form. This is used in the des and | |
5194 | 3des routines to generate a key of the correct parity. Update S/MIME | |
5195 | code to use new functions and hence generate correct parity DES keys. | |
5196 | Add EVP_CHECK_DES_KEY #define to return an error if the key is not | |
5197 | valid (weak or incorrect parity). | |
5198 | [Steve Henson] | |
5199 | ||
5200 | *) Add a local set of CRLs that can be used by X509_verify_cert() as well | |
5201 | as looking them up. This is useful when the verified structure may contain | |
5202 | CRLs, for example PKCS#7 signedData. Modify PKCS7_verify() to use any CRLs | |
5203 | present unless the new PKCS7_NO_CRL flag is asserted. | |
5204 | [Steve Henson] | |
5205 | ||
5206 | *) Extend ASN1 oid configuration module. It now additionally accepts the | |
5207 | syntax: | |
5208 | ||
5209 | shortName = some long name, 1.2.3.4 | |
5210 | [Steve Henson] | |
5211 | ||
5212 | *) Reimplemented the BN_CTX implementation. There is now no more static | |
5213 | limitation on the number of variables it can handle nor the depth of the | |
5214 | "stack" handling for BN_CTX_start()/BN_CTX_end() pairs. The stack | |
5215 | information can now expand as required, and rather than having a single | |
5216 | static array of bignums, BN_CTX now uses a linked-list of such arrays | |
5217 | allowing it to expand on demand whilst maintaining the usefulness of | |
5218 | BN_CTX's "bundling". | |
5219 | [Geoff Thorpe] | |
5220 | ||
5221 | *) Add a missing BN_CTX parameter to the 'rsa_mod_exp' callback in RSA_METHOD | |
5222 | to allow all RSA operations to function using a single BN_CTX. | |
5223 | [Geoff Thorpe] | |
5224 | ||
5225 | *) Preliminary support for certificate policy evaluation and checking. This | |
5226 | is initially intended to pass the tests outlined in "Conformance Testing | |
5227 | of Relying Party Client Certificate Path Processing Logic" v1.07. | |
5228 | [Steve Henson] | |
5229 | ||
5230 | *) bn_dup_expand() has been deprecated, it was introduced in 0.9.7 and | |
5231 | remained unused and not that useful. A variety of other little bignum | |
5232 | tweaks and fixes have also been made continuing on from the audit (see | |
5233 | below). | |
5234 | [Geoff Thorpe] | |
5235 | ||
5236 | *) Constify all or almost all d2i, c2i, s2i and r2i functions, along with | |
5237 | associated ASN1, EVP and SSL functions and old ASN1 macros. | |
5238 | [Richard Levitte] | |
5239 | ||
5240 | *) BN_zero() only needs to set 'top' and 'neg' to zero for correct results, | |
5241 | and this should never fail. So the return value from the use of | |
5242 | BN_set_word() (which can fail due to needless expansion) is now deprecated; | |
5243 | if OPENSSL_NO_DEPRECATED is defined, BN_zero() is a void macro. | |
5244 | [Geoff Thorpe] | |
5245 | ||
5246 | *) BN_CTX_get() should return zero-valued bignums, providing the same | |
5247 | initialised value as BN_new(). | |
5248 | [Geoff Thorpe, suggested by Ulf Möller] | |
5249 | ||
5250 | *) Support for inhibitAnyPolicy certificate extension. | |
5251 | [Steve Henson] | |
5252 | ||
5253 | *) An audit of the BIGNUM code is underway, for which debugging code is | |
5254 | enabled when BN_DEBUG is defined. This makes stricter enforcements on what | |
5255 | is considered valid when processing BIGNUMs, and causes execution to | |
5256 | assert() when a problem is discovered. If BN_DEBUG_RAND is defined, | |
5257 | further steps are taken to deliberately pollute unused data in BIGNUM | |
5258 | structures to try and expose faulty code further on. For now, openssl will | |
5259 | (in its default mode of operation) continue to tolerate the inconsistent | |
5260 | forms that it has tolerated in the past, but authors and packagers should | |
5261 | consider trying openssl and their own applications when compiled with | |
5262 | these debugging symbols defined. It will help highlight potential bugs in | |
5263 | their own code, and will improve the test coverage for OpenSSL itself. At | |
5264 | some point, these tighter rules will become openssl's default to improve | |
5265 | maintainability, though the assert()s and other overheads will remain only | |
5266 | in debugging configurations. See bn.h for more details. | |
5267 | [Geoff Thorpe, Nils Larsch, Ulf Möller] | |
5268 | ||
5269 | *) BN_CTX_init() has been deprecated, as BN_CTX is an opaque structure | |
5270 | that can only be obtained through BN_CTX_new() (which implicitly | |
5271 | initialises it). The presence of this function only made it possible | |
5272 | to overwrite an existing structure (and cause memory leaks). | |
5273 | [Geoff Thorpe] | |
5274 | ||
5275 | *) Because of the callback-based approach for implementing LHASH as a | |
5276 | template type, lh_insert() adds opaque objects to hash-tables and | |
5277 | lh_doall() or lh_doall_arg() are typically used with a destructor callback | |
5278 | to clean up those corresponding objects before destroying the hash table | |
5279 | (and losing the object pointers). So some over-zealous constifications in | |
5280 | LHASH have been relaxed so that lh_insert() does not take (nor store) the | |
5281 | objects as "const" and the lh_doall[_arg] callback wrappers are not | |
5282 | prototyped to have "const" restrictions on the object pointers they are | |
5283 | given (and so aren't required to cast them away any more). | |
5284 | [Geoff Thorpe] | |
5285 | ||
5286 | *) The tmdiff.h API was so ugly and minimal that our own timing utility | |
5287 | (speed) prefers to use its own implementation. The two implementations | |
5288 | haven't been consolidated as yet (volunteers?) but the tmdiff API has had | |
5289 | its object type properly exposed (MS_TM) instead of casting to/from "char | |
5290 | *". This may still change yet if someone realises MS_TM and "ms_time_***" | |
5291 | aren't necessarily the greatest nomenclatures - but this is what was used | |
5292 | internally to the implementation so I've used that for now. | |
5293 | [Geoff Thorpe] | |
5294 | ||
5295 | *) Ensure that deprecated functions do not get compiled when | |
5296 | OPENSSL_NO_DEPRECATED is defined. Some "openssl" subcommands and a few of | |
5297 | the self-tests were still using deprecated key-generation functions so | |
5298 | these have been updated also. | |
5299 | [Geoff Thorpe] | |
5300 | ||
5301 | *) Reorganise PKCS#7 code to separate the digest location functionality | |
5302 | into PKCS7_find_digest(), digest addition into PKCS7_bio_add_digest(). | |
5303 | New function PKCS7_set_digest() to set the digest type for PKCS#7 | |
5304 | digestedData type. Add additional code to correctly generate the | |
5305 | digestedData type and add support for this type in PKCS7 initialization | |
5306 | functions. | |
5307 | [Steve Henson] | |
5308 | ||
5309 | *) New function PKCS7_set0_type_other() this initializes a PKCS7 | |
5310 | structure of type "other". | |
5311 | [Steve Henson] | |
5312 | ||
5313 | *) Fix prime generation loop in crypto/bn/bn_prime.pl by making | |
5314 | sure the loop does correctly stop and breaking ("division by zero") | |
5315 | modulus operations are not performed. The (pre-generated) prime | |
5316 | table crypto/bn/bn_prime.h was already correct, but it could not be | |
5317 | re-generated on some platforms because of the "division by zero" | |
5318 | situation in the script. | |
5319 | [Ralf S. Engelschall] | |
5320 | ||
5321 | *) Update support for ECC-based TLS ciphersuites according to | |
5322 | draft-ietf-tls-ecc-03.txt: the KDF1 key derivation function with | |
5323 | SHA-1 now is only used for "small" curves (where the | |
5324 | representation of a field element takes up to 24 bytes); for | |
5325 | larger curves, the field element resulting from ECDH is directly | |
5326 | used as premaster secret. | |
5327 | [Douglas Stebila (Sun Microsystems Laboratories)] | |
5328 | ||
5329 | *) Add code for kP+lQ timings to crypto/ec/ectest.c, and add SEC2 | |
5330 | curve secp160r1 to the tests. | |
5331 | [Douglas Stebila (Sun Microsystems Laboratories)] | |
5332 | ||
5333 | *) Add the possibility to load symbols globally with DSO. | |
5334 | [Götz Babin-Ebell <babin-ebell@trustcenter.de> via Richard Levitte] | |
5335 | ||
5336 | *) Add the functions ERR_set_mark() and ERR_pop_to_mark() for better | |
5337 | control of the error stack. | |
5338 | [Richard Levitte] | |
5339 | ||
5340 | *) Add support for STORE in ENGINE. | |
5341 | [Richard Levitte] | |
5342 | ||
5343 | *) Add the STORE type. The intention is to provide a common interface | |
5344 | to certificate and key stores, be they simple file-based stores, or | |
5345 | HSM-type store, or LDAP stores, or... | |
5346 | NOTE: The code is currently UNTESTED and isn't really used anywhere. | |
5347 | [Richard Levitte] | |
5348 | ||
5349 | *) Add a generic structure called OPENSSL_ITEM. This can be used to | |
5350 | pass a list of arguments to any function as well as provide a way | |
5351 | for a function to pass data back to the caller. | |
5352 | [Richard Levitte] | |
5353 | ||
5354 | *) Add the functions BUF_strndup() and BUF_memdup(). BUF_strndup() | |
5355 | works like BUF_strdup() but can be used to duplicate a portion of | |
5356 | a string. The copy gets NUL-terminated. BUF_memdup() duplicates | |
5357 | a memory area. | |
5358 | [Richard Levitte] | |
5359 | ||
5360 | *) Add the function sk_find_ex() which works like sk_find(), but will | |
5361 | return an index to an element even if an exact match couldn't be | |
5362 | found. The index is guaranteed to point at the element where the | |
5363 | searched-for key would be inserted to preserve sorting order. | |
5364 | [Richard Levitte] | |
5365 | ||
5366 | *) Add the function OBJ_bsearch_ex() which works like OBJ_bsearch() but | |
5367 | takes an extra flags argument for optional functionality. Currently, | |
5368 | the following flags are defined: | |
5369 | ||
5370 | OBJ_BSEARCH_VALUE_ON_NOMATCH | |
5371 | This one gets OBJ_bsearch_ex() to return a pointer to the first | |
5372 | element where the comparing function returns a negative or zero | |
5373 | number. | |
5374 | ||
5375 | OBJ_BSEARCH_FIRST_VALUE_ON_MATCH | |
5376 | This one gets OBJ_bsearch_ex() to return a pointer to the first | |
5377 | element where the comparing function returns zero. This is useful | |
5378 | if there are more than one element where the comparing function | |
5379 | returns zero. | |
5380 | [Richard Levitte] | |
5381 | ||
5382 | *) Make it possible to create self-signed certificates with 'openssl ca' | |
5383 | in such a way that the self-signed certificate becomes part of the | |
5384 | CA database and uses the same mechanisms for serial number generation | |
5385 | as all other certificate signing. The new flag '-selfsign' enables | |
5386 | this functionality. Adapt CA.sh and CA.pl.in. | |
5387 | [Richard Levitte] | |
5388 | ||
5389 | *) Add functionality to check the public key of a certificate request | |
5390 | against a given private. This is useful to check that a certificate | |
5391 | request can be signed by that key (self-signing). | |
5392 | [Richard Levitte] | |
5393 | ||
5394 | *) Make it possible to have multiple active certificates with the same | |
5395 | subject in the CA index file. This is done only if the keyword | |
5396 | 'unique_subject' is set to 'no' in the main CA section (default | |
5397 | if 'CA_default') of the configuration file. The value is saved | |
5398 | with the database itself in a separate index attribute file, | |
5399 | named like the index file with '.attr' appended to the name. | |
5400 | [Richard Levitte] | |
5401 | ||
5402 | *) Generate multi-valued AVAs using '+' notation in config files for | |
5403 | req and dirName. | |
5404 | [Steve Henson] | |
5405 | ||
5406 | *) Support for nameConstraints certificate extension. | |
5407 | [Steve Henson] | |
5408 | ||
5409 | *) Support for policyConstraints certificate extension. | |
5410 | [Steve Henson] | |
5411 | ||
5412 | *) Support for policyMappings certificate extension. | |
5413 | [Steve Henson] | |
5414 | ||
5415 | *) Make sure the default DSA_METHOD implementation only uses its | |
5416 | dsa_mod_exp() and/or bn_mod_exp() handlers if they are non-NULL, | |
5417 | and change its own handlers to be NULL so as to remove unnecessary | |
5418 | indirection. This lets alternative implementations fallback to the | |
5419 | default implementation more easily. | |
5420 | [Geoff Thorpe] | |
5421 | ||
5422 | *) Support for directoryName in GeneralName related extensions | |
5423 | in config files. | |
5424 | [Steve Henson] | |
5425 | ||
5426 | *) Make it possible to link applications using Makefile.shared. | |
5427 | Make that possible even when linking against static libraries! | |
5428 | [Richard Levitte] | |
5429 | ||
5430 | *) Support for single pass processing for S/MIME signing. This now | |
5431 | means that S/MIME signing can be done from a pipe, in addition | |
5432 | cleartext signing (multipart/signed type) is effectively streaming | |
5433 | and the signed data does not need to be all held in memory. | |
5434 | ||
5435 | This is done with a new flag PKCS7_STREAM. When this flag is set | |
5436 | PKCS7_sign() only initializes the PKCS7 structure and the actual signing | |
5437 | is done after the data is output (and digests calculated) in | |
5438 | SMIME_write_PKCS7(). | |
5439 | [Steve Henson] | |
5440 | ||
5441 | *) Add full support for -rpath/-R, both in shared libraries and | |
5442 | applications, at least on the platforms where it's known how | |
5443 | to do it. | |
5444 | [Richard Levitte] | |
5445 | ||
5446 | *) In crypto/ec/ec_mult.c, implement fast point multiplication with | |
5447 | precomputation, based on wNAF splitting: EC_GROUP_precompute_mult() | |
5448 | will now compute a table of multiples of the generator that | |
5449 | makes subsequent invocations of EC_POINTs_mul() or EC_POINT_mul() | |
5450 | faster (notably in the case of a single point multiplication, | |
5451 | scalar * generator). | |
5452 | [Nils Larsch, Bodo Moeller] | |
5453 | ||
5454 | *) IPv6 support for certificate extensions. The various extensions | |
5455 | which use the IP:a.b.c.d can now take IPv6 addresses using the | |
5456 | formats of RFC1884 2.2 . IPv6 addresses are now also displayed | |
5457 | correctly. | |
5458 | [Steve Henson] | |
5459 | ||
5460 | *) Added an ENGINE that implements RSA by performing private key | |
5461 | exponentiations with the GMP library. The conversions to and from | |
5462 | GMP's mpz_t format aren't optimised nor are any montgomery forms | |
5463 | cached, and on x86 it appears OpenSSL's own performance has caught up. | |
5464 | However there are likely to be other architectures where GMP could | |
5465 | provide a boost. This ENGINE is not built in by default, but it can be | |
5466 | specified at Configure time and should be accompanied by the necessary | |
5467 | linker additions, eg; | |
5468 | ./config -DOPENSSL_USE_GMP -lgmp | |
5469 | [Geoff Thorpe] | |
5470 | ||
5471 | *) "openssl engine" will not display ENGINE/DSO load failure errors when | |
5472 | testing availability of engines with "-t" - the old behaviour is | |
5473 | produced by increasing the feature's verbosity with "-tt". | |
5474 | [Geoff Thorpe] | |
5475 | ||
5476 | *) ECDSA routines: under certain error conditions uninitialized BN objects | |
5477 | could be freed. Solution: make sure initialization is performed early | |
5478 | enough. (Reported and fix supplied by Nils Larsch <nla@trustcenter.de> | |
5479 | via PR#459) | |
5480 | [Lutz Jaenicke] | |
5481 | ||
5482 | *) Key-generation can now be implemented in RSA_METHOD, DSA_METHOD | |
5483 | and DH_METHOD (eg. by ENGINE implementations) to override the normal | |
5484 | software implementations. For DSA and DH, parameter generation can | |
5485 | also be overridden by providing the appropriate method callbacks. | |
5486 | [Geoff Thorpe] | |
5487 | ||
5488 | *) Change the "progress" mechanism used in key-generation and | |
5489 | primality testing to functions that take a new BN_GENCB pointer in | |
5490 | place of callback/argument pairs. The new API functions have "_ex" | |
5491 | postfixes and the older functions are reimplemented as wrappers for | |
5492 | the new ones. The OPENSSL_NO_DEPRECATED symbol can be used to hide | |
5493 | declarations of the old functions to help (graceful) attempts to | |
5494 | migrate to the new functions. Also, the new key-generation API | |
5495 | functions operate on a caller-supplied key-structure and return | |
5496 | success/failure rather than returning a key or NULL - this is to | |
5497 | help make "keygen" another member function of RSA_METHOD etc. | |
5498 | ||
5499 | Example for using the new callback interface: | |
5500 | ||
5501 | int (*my_callback)(int a, int b, BN_GENCB *cb) = ...; | |
5502 | void *my_arg = ...; | |
5503 | BN_GENCB my_cb; | |
5504 | ||
5505 | BN_GENCB_set(&my_cb, my_callback, my_arg); | |
5506 | ||
5507 | return BN_is_prime_ex(some_bignum, BN_prime_checks, NULL, &cb); | |
5508 | /* For the meaning of a, b in calls to my_callback(), see the | |
5509 | * documentation of the function that calls the callback. | |
5510 | * cb will point to my_cb; my_arg can be retrieved as cb->arg. | |
5511 | * my_callback should return 1 if it wants BN_is_prime_ex() | |
5512 | * to continue, or 0 to stop. | |
5513 | */ | |
5514 | ||
5515 | [Geoff Thorpe] | |
5516 | ||
5517 | *) Change the ZLIB compression method to be stateful, and make it | |
5518 | available to TLS with the number defined in | |
5519 | draft-ietf-tls-compression-04.txt. | |
5520 | [Richard Levitte] | |
5521 | ||
5522 | *) Add the ASN.1 structures and functions for CertificatePair, which | |
5523 | is defined as follows (according to X.509_4thEditionDraftV6.pdf): | |
5524 | ||
5525 | CertificatePair ::= SEQUENCE { | |
5526 | forward [0] Certificate OPTIONAL, | |
5527 | reverse [1] Certificate OPTIONAL, | |
5528 | -- at least one of the pair shall be present -- } | |
5529 | ||
5530 | Also implement the PEM functions to read and write certificate | |
5531 | pairs, and defined the PEM tag as "CERTIFICATE PAIR". | |
5532 | ||
5533 | This needed to be defined, mostly for the sake of the LDAP | |
5534 | attribute crossCertificatePair, but may prove useful elsewhere as | |
5535 | well. | |
5536 | [Richard Levitte] | |
5537 | ||
5538 | *) Make it possible to inhibit symlinking of shared libraries in | |
5539 | Makefile.shared, for Cygwin's sake. | |
5540 | [Richard Levitte] | |
5541 | ||
5542 | *) Extend the BIGNUM API by creating a function | |
5543 | void BN_set_negative(BIGNUM *a, int neg); | |
5544 | and a macro that behave like | |
5545 | int BN_is_negative(const BIGNUM *a); | |
5546 | ||
5547 | to avoid the need to access 'a->neg' directly in applications. | |
5548 | [Nils Larsch] | |
5549 | ||
5550 | *) Implement fast modular reduction for pseudo-Mersenne primes | |
5551 | used in NIST curves (crypto/bn/bn_nist.c, crypto/ec/ecp_nist.c). | |
5552 | EC_GROUP_new_curve_GFp() will now automatically use this | |
5553 | if applicable. | |
5554 | [Nils Larsch <nla@trustcenter.de>] | |
5555 | ||
5556 | *) Add new lock type (CRYPTO_LOCK_BN). | |
5557 | [Bodo Moeller] | |
5558 | ||
5559 | *) Change the ENGINE framework to automatically load engines | |
5560 | dynamically from specific directories unless they could be | |
5561 | found to already be built in or loaded. Move all the | |
5562 | current engines except for the cryptodev one to a new | |
5563 | directory engines/. | |
5564 | The engines in engines/ are built as shared libraries if | |
5565 | the "shared" options was given to ./Configure or ./config. | |
5566 | Otherwise, they are inserted in libcrypto.a. | |
5567 | /usr/local/ssl/engines is the default directory for dynamic | |
5568 | engines, but that can be overridden at configure time through | |
5569 | the usual use of --prefix and/or --openssldir, and at run | |
5570 | time with the environment variable OPENSSL_ENGINES. | |
5571 | [Geoff Thorpe and Richard Levitte] | |
5572 | ||
5573 | *) Add Makefile.shared, a helper makefile to build shared | |
5574 | libraries. Adapt Makefile.org. | |
5575 | [Richard Levitte] | |
5576 | ||
5577 | *) Add version info to Win32 DLLs. | |
5578 | [Peter 'Luna' Runestig" <peter@runestig.com>] | |
5579 | ||
5580 | *) Add new 'medium level' PKCS#12 API. Certificates and keys | |
5581 | can be added using this API to created arbitrary PKCS#12 | |
5582 | files while avoiding the low level API. | |
5583 | ||
5584 | New options to PKCS12_create(), key or cert can be NULL and | |
5585 | will then be omitted from the output file. The encryption | |
5586 | algorithm NIDs can be set to -1 for no encryption, the mac | |
5587 | iteration count can be set to 0 to omit the mac. | |
5588 | ||
5589 | Enhance pkcs12 utility by making the -nokeys and -nocerts | |
5590 | options work when creating a PKCS#12 file. New option -nomac | |
5591 | to omit the mac, NONE can be set for an encryption algorithm. | |
5592 | New code is modified to use the enhanced PKCS12_create() | |
5593 | instead of the low level API. | |
5594 | [Steve Henson] | |
5595 | ||
5596 | *) Extend ASN1 encoder to support indefinite length constructed | |
5597 | encoding. This can output sequences tags and octet strings in | |
5598 | this form. Modify pk7_asn1.c to support indefinite length | |
5599 | encoding. This is experimental and needs additional code to | |
5600 | be useful, such as an ASN1 bio and some enhanced streaming | |
5601 | PKCS#7 code. | |
5602 | ||
5603 | Extend template encode functionality so that tagging is passed | |
5604 | down to the template encoder. | |
5605 | [Steve Henson] | |
5606 | ||
5607 | *) Let 'openssl req' fail if an argument to '-newkey' is not | |
5608 | recognized instead of using RSA as a default. | |
5609 | [Bodo Moeller] | |
5610 | ||
5611 | *) Add support for ECC-based ciphersuites from draft-ietf-tls-ecc-01.txt. | |
5612 | As these are not official, they are not included in "ALL"; | |
5613 | the "ECCdraft" ciphersuite group alias can be used to select them. | |
5614 | [Vipul Gupta and Sumit Gupta (Sun Microsystems Laboratories)] | |
5615 | ||
5616 | *) Add ECDH engine support. | |
5617 | [Nils Gura and Douglas Stebila (Sun Microsystems Laboratories)] | |
5618 | ||
5619 | *) Add ECDH in new directory crypto/ecdh/. | |
5620 | [Douglas Stebila (Sun Microsystems Laboratories)] | |
5621 | ||
5622 | *) Let BN_rand_range() abort with an error after 100 iterations | |
5623 | without success (which indicates a broken PRNG). | |
5624 | [Bodo Moeller] | |
5625 | ||
5626 | *) Change BN_mod_sqrt() so that it verifies that the input value | |
5627 | is really the square of the return value. (Previously, | |
5628 | BN_mod_sqrt would show GIGO behaviour.) | |
5629 | [Bodo Moeller] | |
5630 | ||
5631 | *) Add named elliptic curves over binary fields from X9.62, SECG, | |
5632 | and WAP/WTLS; add OIDs that were still missing. | |
5633 | ||
5634 | [Sheueling Chang Shantz and Douglas Stebila | |
5635 | (Sun Microsystems Laboratories)] | |
5636 | ||
5637 | *) Extend the EC library for elliptic curves over binary fields | |
5638 | (new files ec2_smpl.c, ec2_smpt.c, ec2_mult.c in crypto/ec/). | |
5639 | New EC_METHOD: | |
5640 | ||
5641 | EC_GF2m_simple_method | |
5642 | ||
5643 | New API functions: | |
5644 | ||
5645 | EC_GROUP_new_curve_GF2m | |
5646 | EC_GROUP_set_curve_GF2m | |
5647 | EC_GROUP_get_curve_GF2m | |
5648 | EC_POINT_set_affine_coordinates_GF2m | |
5649 | EC_POINT_get_affine_coordinates_GF2m | |
5650 | EC_POINT_set_compressed_coordinates_GF2m | |
5651 | ||
5652 | Point compression for binary fields is disabled by default for | |
5653 | patent reasons (compile with OPENSSL_EC_BIN_PT_COMP defined to | |
5654 | enable it). | |
5655 | ||
5656 | As binary polynomials are represented as BIGNUMs, various members | |
5657 | of the EC_GROUP and EC_POINT data structures can be shared | |
5658 | between the implementations for prime fields and binary fields; | |
5659 | the above ..._GF2m functions (except for EX_GROUP_new_curve_GF2m) | |
5660 | are essentially identical to their ..._GFp counterparts. | |
5661 | (For simplicity, the '..._GFp' prefix has been dropped from | |
5662 | various internal method names.) | |
5663 | ||
5664 | An internal 'field_div' method (similar to 'field_mul' and | |
5665 | 'field_sqr') has been added; this is used only for binary fields. | |
5666 | ||
5667 | [Sheueling Chang Shantz and Douglas Stebila | |
5668 | (Sun Microsystems Laboratories)] | |
5669 | ||
5670 | *) Optionally dispatch EC_POINT_mul(), EC_POINT_precompute_mult() | |
5671 | through methods ('mul', 'precompute_mult'). | |
5672 | ||
5673 | The generic implementations (now internally called 'ec_wNAF_mul' | |
5674 | and 'ec_wNAF_precomputed_mult') remain the default if these | |
5675 | methods are undefined. | |
5676 | ||
5677 | [Sheueling Chang Shantz and Douglas Stebila | |
5678 | (Sun Microsystems Laboratories)] | |
5679 | ||
5680 | *) New function EC_GROUP_get_degree, which is defined through | |
5681 | EC_METHOD. For curves over prime fields, this returns the bit | |
5682 | length of the modulus. | |
5683 | ||
5684 | [Sheueling Chang Shantz and Douglas Stebila | |
5685 | (Sun Microsystems Laboratories)] | |
5686 | ||
5687 | *) New functions EC_GROUP_dup, EC_POINT_dup. | |
5688 | (These simply call ..._new and ..._copy). | |
5689 | ||
5690 | [Sheueling Chang Shantz and Douglas Stebila | |
5691 | (Sun Microsystems Laboratories)] | |
5692 | ||
5693 | *) Add binary polynomial arithmetic software in crypto/bn/bn_gf2m.c. | |
5694 | Polynomials are represented as BIGNUMs (where the sign bit is not | |
5695 | used) in the following functions [macros]: | |
5696 | ||
5697 | BN_GF2m_add | |
5698 | BN_GF2m_sub [= BN_GF2m_add] | |
5699 | BN_GF2m_mod [wrapper for BN_GF2m_mod_arr] | |
5700 | BN_GF2m_mod_mul [wrapper for BN_GF2m_mod_mul_arr] | |
5701 | BN_GF2m_mod_sqr [wrapper for BN_GF2m_mod_sqr_arr] | |
5702 | BN_GF2m_mod_inv | |
5703 | BN_GF2m_mod_exp [wrapper for BN_GF2m_mod_exp_arr] | |
5704 | BN_GF2m_mod_sqrt [wrapper for BN_GF2m_mod_sqrt_arr] | |
5705 | BN_GF2m_mod_solve_quad [wrapper for BN_GF2m_mod_solve_quad_arr] | |
5706 | BN_GF2m_cmp [= BN_ucmp] | |
5707 | ||
5708 | (Note that only the 'mod' functions are actually for fields GF(2^m). | |
5709 | BN_GF2m_add() is misnomer, but this is for the sake of consistency.) | |
5710 | ||
5711 | For some functions, an the irreducible polynomial defining a | |
5712 | field can be given as an 'unsigned int[]' with strictly | |
5713 | decreasing elements giving the indices of those bits that are set; | |
5714 | i.e., p[] represents the polynomial | |
5715 | f(t) = t^p[0] + t^p[1] + ... + t^p[k] | |
5716 | where | |
5717 | p[0] > p[1] > ... > p[k] = 0. | |
5718 | This applies to the following functions: | |
5719 | ||
5720 | BN_GF2m_mod_arr | |
5721 | BN_GF2m_mod_mul_arr | |
5722 | BN_GF2m_mod_sqr_arr | |
5723 | BN_GF2m_mod_inv_arr [wrapper for BN_GF2m_mod_inv] | |
5724 | BN_GF2m_mod_div_arr [wrapper for BN_GF2m_mod_div] | |
5725 | BN_GF2m_mod_exp_arr | |
5726 | BN_GF2m_mod_sqrt_arr | |
5727 | BN_GF2m_mod_solve_quad_arr | |
5728 | BN_GF2m_poly2arr | |
5729 | BN_GF2m_arr2poly | |
5730 | ||
5731 | Conversion can be performed by the following functions: | |
5732 | ||
5733 | BN_GF2m_poly2arr | |
5734 | BN_GF2m_arr2poly | |
5735 | ||
5736 | bntest.c has additional tests for binary polynomial arithmetic. | |
5737 | ||
5738 | Two implementations for BN_GF2m_mod_div() are available. | |
5739 | The default algorithm simply uses BN_GF2m_mod_inv() and | |
5740 | BN_GF2m_mod_mul(). The alternative algorithm is compiled in only | |
5741 | if OPENSSL_SUN_GF2M_DIV is defined (patent pending; read the | |
5742 | copyright notice in crypto/bn/bn_gf2m.c before enabling it). | |
5743 | ||
5744 | [Sheueling Chang Shantz and Douglas Stebila | |
5745 | (Sun Microsystems Laboratories)] | |
5746 | ||
5747 | *) Add new error code 'ERR_R_DISABLED' that can be used when some | |
5748 | functionality is disabled at compile-time. | |
5749 | [Douglas Stebila <douglas.stebila@sun.com>] | |
5750 | ||
5751 | *) Change default behaviour of 'openssl asn1parse' so that more | |
5752 | information is visible when viewing, e.g., a certificate: | |
5753 | ||
5754 | Modify asn1_parse2 (crypto/asn1/asn1_par.c) so that in non-'dump' | |
5755 | mode the content of non-printable OCTET STRINGs is output in a | |
5756 | style similar to INTEGERs, but with '[HEX DUMP]' prepended to | |
5757 | avoid the appearance of a printable string. | |
5758 | [Nils Larsch <nla@trustcenter.de>] | |
5759 | ||
5760 | *) Add 'asn1_flag' and 'asn1_form' member to EC_GROUP with access | |
5761 | functions | |
5762 | EC_GROUP_set_asn1_flag() | |
5763 | EC_GROUP_get_asn1_flag() | |
5764 | EC_GROUP_set_point_conversion_form() | |
5765 | EC_GROUP_get_point_conversion_form() | |
5766 | These control ASN1 encoding details: | |
5767 | - Curves (i.e., groups) are encoded explicitly unless asn1_flag | |
5768 | has been set to OPENSSL_EC_NAMED_CURVE. | |
5769 | - Points are encoded in uncompressed form by default; options for | |
5770 | asn1_for are as for point2oct, namely | |
5771 | POINT_CONVERSION_COMPRESSED | |
5772 | POINT_CONVERSION_UNCOMPRESSED | |
5773 | POINT_CONVERSION_HYBRID | |
5774 | ||
5775 | Also add 'seed' and 'seed_len' members to EC_GROUP with access | |
5776 | functions | |
5777 | EC_GROUP_set_seed() | |
5778 | EC_GROUP_get0_seed() | |
5779 | EC_GROUP_get_seed_len() | |
5780 | This is used only for ASN1 purposes (so far). | |
5781 | [Nils Larsch <nla@trustcenter.de>] | |
5782 | ||
5783 | *) Add 'field_type' member to EC_METHOD, which holds the NID | |
5784 | of the appropriate field type OID. The new function | |
5785 | EC_METHOD_get_field_type() returns this value. | |
5786 | [Nils Larsch <nla@trustcenter.de>] | |
5787 | ||
5788 | *) Add functions | |
5789 | EC_POINT_point2bn() | |
5790 | EC_POINT_bn2point() | |
5791 | EC_POINT_point2hex() | |
5792 | EC_POINT_hex2point() | |
5793 | providing useful interfaces to EC_POINT_point2oct() and | |
5794 | EC_POINT_oct2point(). | |
5795 | [Nils Larsch <nla@trustcenter.de>] | |
5796 | ||
5797 | *) Change internals of the EC library so that the functions | |
5798 | EC_GROUP_set_generator() | |
5799 | EC_GROUP_get_generator() | |
5800 | EC_GROUP_get_order() | |
5801 | EC_GROUP_get_cofactor() | |
5802 | are implemented directly in crypto/ec/ec_lib.c and not dispatched | |
5803 | to methods, which would lead to unnecessary code duplication when | |
5804 | adding different types of curves. | |
5805 | [Nils Larsch <nla@trustcenter.de> with input by Bodo Moeller] | |
5806 | ||
5807 | *) Implement compute_wNAF (crypto/ec/ec_mult.c) without BIGNUM | |
5808 | arithmetic, and such that modified wNAFs are generated | |
5809 | (which avoid length expansion in many cases). | |
5810 | [Bodo Moeller] | |
5811 | ||
5812 | *) Add a function EC_GROUP_check_discriminant() (defined via | |
5813 | EC_METHOD) that verifies that the curve discriminant is non-zero. | |
5814 | ||
5815 | Add a function EC_GROUP_check() that makes some sanity tests | |
5816 | on a EC_GROUP, its generator and order. This includes | |
5817 | EC_GROUP_check_discriminant(). | |
5818 | [Nils Larsch <nla@trustcenter.de>] | |
5819 | ||
5820 | *) Add ECDSA in new directory crypto/ecdsa/. | |
5821 | ||
5822 | Add applications 'openssl ecparam' and 'openssl ecdsa' | |
5823 | (these are based on 'openssl dsaparam' and 'openssl dsa'). | |
5824 | ||
5825 | ECDSA support is also included in various other files across the | |
5826 | library. Most notably, | |
5827 | - 'openssl req' now has a '-newkey ecdsa:file' option; | |
5828 | - EVP_PKCS82PKEY (crypto/evp/evp_pkey.c) now can handle ECDSA; | |
5829 | - X509_PUBKEY_get (crypto/asn1/x_pubkey.c) and | |
5830 | d2i_PublicKey (crypto/asn1/d2i_pu.c) have been modified to make | |
5831 | them suitable for ECDSA where domain parameters must be | |
5832 | extracted before the specific public key; | |
5833 | - ECDSA engine support has been added. | |
5834 | [Nils Larsch <nla@trustcenter.de>] | |
5835 | ||
5836 | *) Include some named elliptic curves, and add OIDs from X9.62, | |
5837 | SECG, and WAP/WTLS. Each curve can be obtained from the new | |
5838 | function | |
5839 | EC_GROUP_new_by_curve_name(), | |
5840 | and the list of available named curves can be obtained with | |
5841 | EC_get_builtin_curves(). | |
5842 | Also add a 'curve_name' member to EC_GROUP objects, which can be | |
5843 | accessed via | |
5844 | EC_GROUP_set_curve_name() | |
5845 | EC_GROUP_get_curve_name() | |
5846 | [Nils Larsch <larsch@trustcenter.de, Bodo Moeller] | |
5847 | ||
5848 | *) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there | |
5849 | was actually never needed) and in BN_mul(). The removal in BN_mul() | |
5850 | required a small change in bn_mul_part_recursive() and the addition | |
5851 | of the functions bn_cmp_part_words(), bn_sub_part_words() and | |
5852 | bn_add_part_words(), which do the same thing as bn_cmp_words(), | |
5853 | bn_sub_words() and bn_add_words() except they take arrays with | |
5854 | differing sizes. | |
5855 | [Richard Levitte] | |
5856 | ||
5857 | Changes between 0.9.7l and 0.9.7m [23 Feb 2007] | |
5858 | ||
5859 | *) Cleanse PEM buffers before freeing them since they may contain | |
5860 | sensitive data. | |
5861 | [Benjamin Bennett <ben@psc.edu>] | |
5862 | ||
5863 | *) Include "!eNULL" in SSL_DEFAULT_CIPHER_LIST to make sure that | |
5864 | a ciphersuite string such as "DEFAULT:RSA" cannot enable | |
5865 | authentication-only ciphersuites. | |
5866 | [Bodo Moeller] | |
5867 | ||
5868 | *) Since AES128 and AES256 share a single mask bit in the logic of | |
5869 | ssl/ssl_ciph.c, the code for masking out disabled ciphers needs a | |
5870 | kludge to work properly if AES128 is available and AES256 isn't. | |
5871 | [Victor Duchovni] | |
5872 | ||
5873 | *) Expand security boundary to match 1.1.1 module. | |
5874 | [Steve Henson] | |
5875 | ||
5876 | *) Remove redundant features: hash file source, editing of test vectors | |
5877 | modify fipsld to use external fips_premain.c signature. | |
5878 | [Steve Henson] | |
5879 | ||
5880 | *) New perl script mkfipsscr.pl to create shell scripts or batch files to | |
5881 | run algorithm test programs. | |
5882 | [Steve Henson] | |
5883 | ||
5884 | *) Make algorithm test programs more tolerant of whitespace. | |
5885 | [Steve Henson] | |
5886 | ||
5887 | *) Have SSL/TLS server implementation tolerate "mismatched" record | |
5888 | protocol version while receiving ClientHello even if the | |
5889 | ClientHello is fragmented. (The server can't insist on the | |
5890 | particular protocol version it has chosen before the ServerHello | |
5891 | message has informed the client about his choice.) | |
5892 | [Bodo Moeller] | |
5893 | ||
5894 | *) Load error codes if they are not already present instead of using a | |
5895 | static variable. This allows them to be cleanly unloaded and reloaded. | |
5896 | [Steve Henson] | |
5897 | ||
5898 | Changes between 0.9.7k and 0.9.7l [28 Sep 2006] | |
5899 | ||
5900 | *) Introduce limits to prevent malicious keys being able to | |
5901 | cause a denial of service. (CVE-2006-2940) | |
5902 | [Steve Henson, Bodo Moeller] | |
5903 | ||
5904 | *) Fix ASN.1 parsing of certain invalid structures that can result | |
5905 | in a denial of service. (CVE-2006-2937) [Steve Henson] | |
5906 | ||
5907 | *) Fix buffer overflow in SSL_get_shared_ciphers() function. | |
5908 | (CVE-2006-3738) [Tavis Ormandy and Will Drewry, Google Security Team] | |
5909 | ||
5910 | *) Fix SSL client code which could crash if connecting to a | |
5911 | malicious SSLv2 server. (CVE-2006-4343) | |
5912 | [Tavis Ormandy and Will Drewry, Google Security Team] | |
5913 | ||
5914 | *) Change ciphersuite string processing so that an explicit | |
5915 | ciphersuite selects this one ciphersuite (so that "AES256-SHA" | |
5916 | will no longer include "AES128-SHA"), and any other similar | |
5917 | ciphersuite (same bitmap) from *other* protocol versions (so that | |
5918 | "RC4-MD5" will still include both the SSL 2.0 ciphersuite and the | |
5919 | SSL 3.0/TLS 1.0 ciphersuite). This is a backport combining | |
5920 | changes from 0.9.8b and 0.9.8d. | |
5921 | [Bodo Moeller] | |
5922 | ||
5923 | Changes between 0.9.7j and 0.9.7k [05 Sep 2006] | |
5924 | ||
5925 | *) Avoid PKCS #1 v1.5 signature attack discovered by Daniel Bleichenbacher | |
5926 | (CVE-2006-4339) [Ben Laurie and Google Security Team] | |
5927 | ||
5928 | *) Change the Unix randomness entropy gathering to use poll() when | |
5929 | possible instead of select(), since the latter has some | |
5930 | undesirable limitations. | |
5931 | [Darryl Miles via Richard Levitte and Bodo Moeller] | |
5932 | ||
5933 | *) Disable rogue ciphersuites: | |
5934 | ||
5935 | - SSLv2 0x08 0x00 0x80 ("RC4-64-MD5") | |
5936 | - SSLv3/TLSv1 0x00 0x61 ("EXP1024-RC2-CBC-MD5") | |
5937 | - SSLv3/TLSv1 0x00 0x60 ("EXP1024-RC4-MD5") | |
5938 | ||
5939 | The latter two were purportedly from | |
5940 | draft-ietf-tls-56-bit-ciphersuites-0[01].txt, but do not really | |
5941 | appear there. | |
5942 | ||
5943 | Also deactivate the remaining ciphersuites from | |
5944 | draft-ietf-tls-56-bit-ciphersuites-01.txt. These are just as | |
5945 | unofficial, and the ID has long expired. | |
5946 | [Bodo Moeller] | |
5947 | ||
5948 | *) Fix RSA blinding Heisenbug (problems sometimes occurred on | |
5949 | dual-core machines) and other potential thread-safety issues. | |
5950 | [Bodo Moeller] | |
5951 | ||
5952 | Changes between 0.9.7i and 0.9.7j [04 May 2006] | |
5953 | ||
5954 | *) Adapt fipsld and the build system to link against the validated FIPS | |
5955 | module in FIPS mode. | |
5956 | [Steve Henson] | |
5957 | ||
5958 | *) Fixes for VC++ 2005 build under Windows. | |
5959 | [Steve Henson] | |
5960 | ||
5961 | *) Add new Windows build target VC-32-GMAKE for VC++. This uses GNU make | |
5962 | from a Windows bash shell such as MSYS. It is autodetected from the | |
5963 | "config" script when run from a VC++ environment. Modify standard VC++ | |
5964 | build to use fipscanister.o from the GNU make build. | |
5965 | [Steve Henson] | |
5966 | ||
5967 | Changes between 0.9.7h and 0.9.7i [14 Oct 2005] | |
5968 | ||
5969 | *) Wrapped the definition of EVP_MAX_MD_SIZE in a #ifdef OPENSSL_FIPS. | |
5970 | The value now differs depending on if you build for FIPS or not. | |
5971 | BEWARE! A program linked with a shared FIPSed libcrypto can't be | |
5972 | safely run with a non-FIPSed libcrypto, as it may crash because of | |
5973 | the difference induced by this change. | |
5974 | [Andy Polyakov] | |
5975 | ||
5976 | Changes between 0.9.7g and 0.9.7h [11 Oct 2005] | |
5977 | ||
5978 | *) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING | |
5979 | (part of SSL_OP_ALL). This option used to disable the | |
5980 | countermeasure against man-in-the-middle protocol-version | |
5981 | rollback in the SSL 2.0 server implementation, which is a bad | |
5982 | idea. (CVE-2005-2969) | |
5983 | ||
5984 | [Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center | |
5985 | for Information Security, National Institute of Advanced Industrial | |
5986 | Science and Technology [AIST], Japan)] | |
5987 | ||
5988 | *) Minimal support for X9.31 signatures and PSS padding modes. This is | |
5989 | mainly for FIPS compliance and not fully integrated at this stage. | |
5990 | [Steve Henson] | |
5991 | ||
5992 | *) For DSA signing, unless DSA_FLAG_NO_EXP_CONSTTIME is set, perform | |
5993 | the exponentiation using a fixed-length exponent. (Otherwise, | |
5994 | the information leaked through timing could expose the secret key | |
5995 | after many signatures; cf. Bleichenbacher's attack on DSA with | |
5996 | biased k.) | |
5997 | [Bodo Moeller] | |
5998 | ||
5999 | *) Make a new fixed-window mod_exp implementation the default for | |
6000 | RSA, DSA, and DH private-key operations so that the sequence of | |
6001 | squares and multiplies and the memory access pattern are | |
6002 | independent of the particular secret key. This will mitigate | |
6003 | cache-timing and potential related attacks. | |
6004 | ||
6005 | BN_mod_exp_mont_consttime() is the new exponentiation implementation, | |
6006 | and this is automatically used by BN_mod_exp_mont() if the new flag | |
6007 | BN_FLG_EXP_CONSTTIME is set for the exponent. RSA, DSA, and DH | |
6008 | will use this BN flag for private exponents unless the flag | |
6009 | RSA_FLAG_NO_EXP_CONSTTIME, DSA_FLAG_NO_EXP_CONSTTIME, or | |
6010 | DH_FLAG_NO_EXP_CONSTTIME, respectively, is set. | |
6011 | ||
6012 | [Matthew D Wood (Intel Corp), with some changes by Bodo Moeller] | |
6013 | ||
6014 | *) Change the client implementation for SSLv23_method() and | |
6015 | SSLv23_client_method() so that is uses the SSL 3.0/TLS 1.0 | |
6016 | Client Hello message format if the SSL_OP_NO_SSLv2 option is set. | |
6017 | (Previously, the SSL 2.0 backwards compatible Client Hello | |
6018 | message format would be used even with SSL_OP_NO_SSLv2.) | |
6019 | [Bodo Moeller] | |
6020 | ||
6021 | *) Add support for smime-type MIME parameter in S/MIME messages which some | |
6022 | clients need. | |
6023 | [Steve Henson] | |
6024 | ||
6025 | *) New function BN_MONT_CTX_set_locked() to set montgomery parameters in | |
6026 | a threadsafe manner. Modify rsa code to use new function and add calls | |
6027 | to dsa and dh code (which had race conditions before). | |
6028 | [Steve Henson] | |
6029 | ||
6030 | *) Include the fixed error library code in the C error file definitions | |
6031 | instead of fixing them up at runtime. This keeps the error code | |
6032 | structures constant. | |
6033 | [Steve Henson] | |
6034 | ||
6035 | Changes between 0.9.7f and 0.9.7g [11 Apr 2005] | |
6036 | ||
6037 | [NB: OpenSSL 0.9.7h and later 0.9.7 patch levels were released after | |
6038 | OpenSSL 0.9.8.] | |
6039 | ||
6040 | *) Fixes for newer kerberos headers. NB: the casts are needed because | |
6041 | the 'length' field is signed on one version and unsigned on another | |
6042 | with no (?) obvious way to tell the difference, without these VC++ | |
6043 | complains. Also the "definition" of FAR (blank) is no longer included | |
6044 | nor is the error ENOMEM. KRB5_PRIVATE has to be set to 1 to pick up | |
6045 | some needed definitions. | |
6046 | [Steve Henson] | |
6047 | ||
6048 | *) Undo Cygwin change. | |
6049 | [Ulf Möller] | |
6050 | ||
6051 | *) Added support for proxy certificates according to RFC 3820. | |
6052 | Because they may be a security thread to unaware applications, | |
6053 | they must be explicitly allowed in run-time. See | |
6054 | docs/HOWTO/proxy_certificates.txt for further information. | |
6055 | [Richard Levitte] | |
6056 | ||
6057 | Changes between 0.9.7e and 0.9.7f [22 Mar 2005] | |
6058 | ||
6059 | *) Use (SSL_RANDOM_VALUE - 4) bytes of pseudo random data when generating | |
6060 | server and client random values. Previously | |
6061 | (SSL_RANDOM_VALUE - sizeof(time_t)) would be used which would result in | |
6062 | less random data when sizeof(time_t) > 4 (some 64 bit platforms). | |
6063 | ||
6064 | This change has negligible security impact because: | |
6065 | ||
6066 | 1. Server and client random values still have 24 bytes of pseudo random | |
6067 | data. | |
6068 | ||
6069 | 2. Server and client random values are sent in the clear in the initial | |
6070 | handshake. | |
6071 | ||
6072 | 3. The master secret is derived using the premaster secret (48 bytes in | |
6073 | size for static RSA ciphersuites) as well as client server and random | |
6074 | values. | |
6075 | ||
6076 | The OpenSSL team would like to thank the UK NISCC for bringing this issue | |
6077 | to our attention. | |
6078 | ||
6079 | [Stephen Henson, reported by UK NISCC] | |
6080 | ||
6081 | *) Use Windows randomness collection on Cygwin. | |
6082 | [Ulf Möller] | |
6083 | ||
6084 | *) Fix hang in EGD/PRNGD query when communication socket is closed | |
6085 | prematurely by EGD/PRNGD. | |
6086 | [Darren Tucker <dtucker@zip.com.au> via Lutz Jänicke, resolves #1014] | |
6087 | ||
6088 | *) Prompt for pass phrases when appropriate for PKCS12 input format. | |
6089 | [Steve Henson] | |
6090 | ||
6091 | *) Back-port of selected performance improvements from development | |
6092 | branch, as well as improved support for PowerPC platforms. | |
6093 | [Andy Polyakov] | |
6094 | ||
6095 | *) Add lots of checks for memory allocation failure, error codes to indicate | |
6096 | failure and freeing up memory if a failure occurs. | |
6097 | [Nauticus Networks SSL Team <openssl@nauticusnet.com>, Steve Henson] | |
6098 | ||
6099 | *) Add new -passin argument to dgst. | |
6100 | [Steve Henson] | |
6101 | ||
6102 | *) Perform some character comparisons of different types in X509_NAME_cmp: | |
6103 | this is needed for some certificates that re-encode DNs into UTF8Strings | |
6104 | (in violation of RFC3280) and can't or won't issue name rollover | |
6105 | certificates. | |
6106 | [Steve Henson] | |
6107 | ||
6108 | *) Make an explicit check during certificate validation to see that | |
6109 | the CA setting in each certificate on the chain is correct. As a | |
6110 | side effect always do the following basic checks on extensions, | |
6111 | not just when there's an associated purpose to the check: | |
6112 | ||
6113 | - if there is an unhandled critical extension (unless the user | |
6114 | has chosen to ignore this fault) | |
6115 | - if the path length has been exceeded (if one is set at all) | |
6116 | - that certain extensions fit the associated purpose (if one has | |
6117 | been given) | |
6118 | [Richard Levitte] | |
6119 | ||
6120 | Changes between 0.9.7d and 0.9.7e [25 Oct 2004] | |
6121 | ||
6122 | *) Avoid a race condition when CRLs are checked in a multi threaded | |
6123 | environment. This would happen due to the reordering of the revoked | |
6124 | entries during signature checking and serial number lookup. Now the | |
6125 | encoding is cached and the serial number sort performed under a lock. | |
6126 | Add new STACK function sk_is_sorted(). | |
6127 | [Steve Henson] | |
6128 | ||
6129 | *) Add Delta CRL to the extension code. | |
6130 | [Steve Henson] | |
6131 | ||
6132 | *) Various fixes to s3_pkt.c so alerts are sent properly. | |
6133 | [David Holmes <d.holmes@f5.com>] | |
6134 | ||
6135 | *) Reduce the chances of duplicate issuer name and serial numbers (in | |
6136 | violation of RFC3280) using the OpenSSL certificate creation utilities. | |
6137 | This is done by creating a random 64 bit value for the initial serial | |
6138 | number when a serial number file is created or when a self signed | |
6139 | certificate is created using 'openssl req -x509'. The initial serial | |
6140 | number file is created using 'openssl x509 -next_serial' in CA.pl | |
6141 | rather than being initialized to 1. | |
6142 | [Steve Henson] | |
6143 | ||
6144 | Changes between 0.9.7c and 0.9.7d [17 Mar 2004] | |
6145 | ||
6146 | *) Fix null-pointer assignment in do_change_cipher_spec() revealed | |
6147 | by using the Codenomicon TLS Test Tool (CVE-2004-0079) | |
6148 | [Joe Orton, Steve Henson] | |
6149 | ||
6150 | *) Fix flaw in SSL/TLS handshaking when using Kerberos ciphersuites | |
6151 | (CVE-2004-0112) | |
6152 | [Joe Orton, Steve Henson] | |
6153 | ||
6154 | *) Make it possible to have multiple active certificates with the same | |
6155 | subject in the CA index file. This is done only if the keyword | |
6156 | 'unique_subject' is set to 'no' in the main CA section (default | |
6157 | if 'CA_default') of the configuration file. The value is saved | |
6158 | with the database itself in a separate index attribute file, | |
6159 | named like the index file with '.attr' appended to the name. | |
6160 | [Richard Levitte] | |
6161 | ||
6162 | *) X509 verify fixes. Disable broken certificate workarounds when | |
6163 | X509_V_FLAGS_X509_STRICT is set. Check CRL issuer has cRLSign set if | |
6164 | keyUsage extension present. Don't accept CRLs with unhandled critical | |
6165 | extensions: since verify currently doesn't process CRL extensions this | |
6166 | rejects a CRL with *any* critical extensions. Add new verify error codes | |
6167 | for these cases. | |
6168 | [Steve Henson] | |
6169 | ||
6170 | *) When creating an OCSP nonce use an OCTET STRING inside the extnValue. | |
6171 | A clarification of RFC2560 will require the use of OCTET STRINGs and | |
6172 | some implementations cannot handle the current raw format. Since OpenSSL | |
6173 | copies and compares OCSP nonces as opaque blobs without any attempt at | |
6174 | parsing them this should not create any compatibility issues. | |
6175 | [Steve Henson] | |
6176 | ||
6177 | *) New md flag EVP_MD_CTX_FLAG_REUSE this allows md_data to be reused when | |
6178 | calling EVP_MD_CTX_copy_ex() to avoid calling OPENSSL_malloc(). Without | |
6179 | this HMAC (and other) operations are several times slower than OpenSSL | |
6180 | < 0.9.7. | |
6181 | [Steve Henson] | |
6182 | ||
6183 | *) Print out GeneralizedTime and UTCTime in ASN1_STRING_print_ex(). | |
6184 | [Peter Sylvester <Peter.Sylvester@EdelWeb.fr>] | |
6185 | ||
6186 | *) Use the correct content when signing type "other". | |
6187 | [Steve Henson] | |
6188 | ||
6189 | Changes between 0.9.7b and 0.9.7c [30 Sep 2003] | |
6190 | ||
6191 | *) Fix various bugs revealed by running the NISCC test suite: | |
6192 | ||
6193 | Stop out of bounds reads in the ASN1 code when presented with | |
6194 | invalid tags (CVE-2003-0543 and CVE-2003-0544). | |
6195 | ||
6196 | Free up ASN1_TYPE correctly if ANY type is invalid (CVE-2003-0545). | |
6197 | ||
6198 | If verify callback ignores invalid public key errors don't try to check | |
6199 | certificate signature with the NULL public key. | |
6200 | ||
6201 | [Steve Henson] | |
6202 | ||
6203 | *) New -ignore_err option in ocsp application to stop the server | |
6204 | exiting on the first error in a request. | |
6205 | [Steve Henson] | |
6206 | ||
6207 | *) In ssl3_accept() (ssl/s3_srvr.c) only accept a client certificate | |
6208 | if the server requested one: as stated in TLS 1.0 and SSL 3.0 | |
6209 | specifications. | |
6210 | [Steve Henson] | |
6211 | ||
6212 | *) In ssl3_get_client_hello() (ssl/s3_srvr.c), tolerate additional | |
6213 | extra data after the compression methods not only for TLS 1.0 | |
6214 | but also for SSL 3.0 (as required by the specification). | |
6215 | [Bodo Moeller; problem pointed out by Matthias Loepfe] | |
6216 | ||
6217 | *) Change X509_certificate_type() to mark the key as exported/exportable | |
6218 | when it's 512 *bits* long, not 512 bytes. | |
6219 | [Richard Levitte] | |
6220 | ||
6221 | *) Change AES_cbc_encrypt() so it outputs exact multiple of | |
6222 | blocks during encryption. | |
6223 | [Richard Levitte] | |
6224 | ||
6225 | *) Various fixes to base64 BIO and non blocking I/O. On write | |
6226 | flushes were not handled properly if the BIO retried. On read | |
6227 | data was not being buffered properly and had various logic bugs. | |
6228 | This also affects blocking I/O when the data being decoded is a | |
6229 | certain size. | |
6230 | [Steve Henson] | |
6231 | ||
6232 | *) Various S/MIME bugfixes and compatibility changes: | |
6233 | output correct application/pkcs7 MIME type if | |
6234 | PKCS7_NOOLDMIMETYPE is set. Tolerate some broken signatures. | |
6235 | Output CR+LF for EOL if PKCS7_CRLFEOL is set (this makes opening | |
6236 | of files as .eml work). Correctly handle very long lines in MIME | |
6237 | parser. | |
6238 | [Steve Henson] | |
6239 | ||
6240 | Changes between 0.9.7a and 0.9.7b [10 Apr 2003] | |
6241 | ||
6242 | *) Countermeasure against the Klima-Pokorny-Rosa extension of | |
6243 | Bleichbacher's attack on PKCS #1 v1.5 padding: treat | |
6244 | a protocol version number mismatch like a decryption error | |
6245 | in ssl3_get_client_key_exchange (ssl/s3_srvr.c). | |
6246 | [Bodo Moeller] | |
6247 | ||
6248 | *) Turn on RSA blinding by default in the default implementation | |
6249 | to avoid a timing attack. Applications that don't want it can call | |
6250 | RSA_blinding_off() or use the new flag RSA_FLAG_NO_BLINDING. | |
6251 | They would be ill-advised to do so in most cases. | |
6252 | [Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller] | |
6253 | ||
6254 | *) Change RSA blinding code so that it works when the PRNG is not | |
6255 | seeded (in this case, the secret RSA exponent is abused as | |
6256 | an unpredictable seed -- if it is not unpredictable, there | |
6257 | is no point in blinding anyway). Make RSA blinding thread-safe | |
6258 | by remembering the creator's thread ID in rsa->blinding and | |
6259 | having all other threads use local one-time blinding factors | |
6260 | (this requires more computation than sharing rsa->blinding, but | |
6261 | avoids excessive locking; and if an RSA object is not shared | |
6262 | between threads, blinding will still be very fast). | |
6263 | [Bodo Moeller] | |
6264 | ||
6265 | *) Fixed a typo bug that would cause ENGINE_set_default() to set an | |
6266 | ENGINE as defaults for all supported algorithms irrespective of | |
6267 | the 'flags' parameter. 'flags' is now honoured, so applications | |
6268 | should make sure they are passing it correctly. | |
6269 | [Geoff Thorpe] | |
6270 | ||
6271 | *) Target "mingw" now allows native Windows code to be generated in | |
6272 | the Cygwin environment as well as with the MinGW compiler. | |
6273 | [Ulf Moeller] | |
6274 | ||
6275 | Changes between 0.9.7 and 0.9.7a [19 Feb 2003] | |
6276 | ||
6277 | *) In ssl3_get_record (ssl/s3_pkt.c), minimize information leaked | |
6278 | via timing by performing a MAC computation even if incorrect | |
6279 | block cipher padding has been found. This is a countermeasure | |
6280 | against active attacks where the attacker has to distinguish | |
6281 | between bad padding and a MAC verification error. (CVE-2003-0078) | |
6282 | ||
6283 | [Bodo Moeller; problem pointed out by Brice Canvel (EPFL), | |
6284 | Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and | |
6285 | Martin Vuagnoux (EPFL, Ilion)] | |
6286 | ||
6287 | *) Make the no-err option work as intended. The intention with no-err | |
6288 | is not to have the whole error stack handling routines removed from | |
6289 | libcrypto, it's only intended to remove all the function name and | |
6290 | reason texts, thereby removing some of the footprint that may not | |
6291 | be interesting if those errors aren't displayed anyway. | |
6292 | ||
6293 | NOTE: it's still possible for any application or module to have it's | |
6294 | own set of error texts inserted. The routines are there, just not | |
6295 | used by default when no-err is given. | |
6296 | [Richard Levitte] | |
6297 | ||
6298 | *) Add support for FreeBSD on IA64. | |
6299 | [dirk.meyer@dinoex.sub.org via Richard Levitte, resolves #454] | |
6300 | ||
6301 | *) Adjust DES_cbc_cksum() so it returns the same value as the MIT | |
6302 | Kerberos function mit_des_cbc_cksum(). Before this change, | |
6303 | the value returned by DES_cbc_cksum() was like the one from | |
6304 | mit_des_cbc_cksum(), except the bytes were swapped. | |
6305 | [Kevin Greaney <Kevin.Greaney@hp.com> and Richard Levitte] | |
6306 | ||
6307 | *) Allow an application to disable the automatic SSL chain building. | |
6308 | Before this a rather primitive chain build was always performed in | |
6309 | ssl3_output_cert_chain(): an application had no way to send the | |
6310 | correct chain if the automatic operation produced an incorrect result. | |
6311 | ||
6312 | Now the chain builder is disabled if either: | |
6313 | ||
6314 | 1. Extra certificates are added via SSL_CTX_add_extra_chain_cert(). | |
6315 | ||
6316 | 2. The mode flag SSL_MODE_NO_AUTO_CHAIN is set. | |
6317 | ||
6318 | The reasoning behind this is that an application would not want the | |
6319 | auto chain building to take place if extra chain certificates are | |
6320 | present and it might also want a means of sending no additional | |
6321 | certificates (for example the chain has two certificates and the | |
6322 | root is omitted). | |
6323 | [Steve Henson] | |
6324 | ||
6325 | *) Add the possibility to build without the ENGINE framework. | |
6326 | [Steven Reddie <smr@essemer.com.au> via Richard Levitte] | |
6327 | ||
6328 | *) Under Win32 gmtime() can return NULL: check return value in | |
6329 | OPENSSL_gmtime(). Add error code for case where gmtime() fails. | |
6330 | [Steve Henson] | |
6331 | ||
6332 | *) DSA routines: under certain error conditions uninitialized BN objects | |
6333 | could be freed. Solution: make sure initialization is performed early | |
6334 | enough. (Reported and fix supplied by Ivan D Nestlerode <nestler@MIT.EDU>, | |
6335 | Nils Larsch <nla@trustcenter.de> via PR#459) | |
6336 | [Lutz Jaenicke] | |
6337 | ||
6338 | *) Another fix for SSLv2 session ID handling: the session ID was incorrectly | |
6339 | checked on reconnect on the client side, therefore session resumption | |
6340 | could still fail with a "ssl session id is different" error. This | |
6341 | behaviour is masked when SSL_OP_ALL is used due to | |
6342 | SSL_OP_MICROSOFT_SESS_ID_BUG being set. | |
6343 | Behaviour observed by Crispin Flowerday <crispin@flowerday.cx> as | |
6344 | followup to PR #377. | |
6345 | [Lutz Jaenicke] | |
6346 | ||
6347 | *) IA-32 assembler support enhancements: unified ELF targets, support | |
6348 | for SCO/Caldera platforms, fix for Cygwin shared build. | |
6349 | [Andy Polyakov] | |
6350 | ||
6351 | *) Add support for FreeBSD on sparc64. As a consequence, support for | |
6352 | FreeBSD on non-x86 processors is separate from x86 processors on | |
6353 | the config script, much like the NetBSD support. | |

6356 | Changes between 0.9.6h and 0.9.7 [31 Dec 2002] | |
6357 | ||
6358 | [NB: OpenSSL 0.9.6i and later 0.9.6 patch levels were released after | |
6359 | OpenSSL 0.9.7.] | |
6360 | ||
6361 | *) Fix session ID handling in SSLv2 client code: the SERVER FINISHED | |
6362 | code (06) was taken as the first octet of the session ID and the last | |
6363 | octet was ignored consequently. As a result SSLv2 client side session | |
6364 | caching could not have worked due to the session ID mismatch between | |
6365 | client and server. | |
6366 | Behaviour observed by Crispin Flowerday <crispin@flowerday.cx> as | |
6367 | PR #377. | |
6368 | [Lutz Jaenicke] | |
6369 | ||
6370 | *) Change the declaration of needed Kerberos libraries to use EX_LIBS | |
6371 | instead of the special (and badly supported) LIBKRB5. LIBKRB5 is | |
6372 | removed entirely. | |
6373 | [Richard Levitte] | |
6374 | ||
6375 | *) The hw_ncipher.c engine requires dynamic locks. Unfortunately, it | |
6376 | seems that in spite of existing for more than a year, many application | |
6377 | author have done nothing to provide the necessary callbacks, which | |
6378 | means that this particular engine will not work properly anywhere. | |
6379 | This is a very unfortunate situation which forces us, in the name | |
6380 | of usability, to give the hw_ncipher.c a static lock, which is part | |
6381 | of libcrypto. | |
6382 | NOTE: This is for the 0.9.7 series ONLY. This hack will never | |
6383 | appear in 0.9.8 or later. We EXPECT application authors to have | |
6384 | dealt properly with this when 0.9.8 is released (unless we actually | |
6385 | make such changes in the libcrypto locking code that changes will | |
6386 | have to be made anyway). | |
6387 | [Richard Levitte] | |
6388 | ||
6389 | *) In asn1_d2i_read_bio() repeatedly call BIO_read() until all content | |
6390 | octets have been read, EOF or an error occurs. Without this change | |
6391 | some truncated ASN1 structures will not produce an error. | |
6392 | [Steve Henson] | |
6393 | ||
6394 | *) Disable Heimdal support, since it hasn't been fully implemented. | |
6395 | Still give the possibility to force the use of Heimdal, but with | |
6396 | warnings and a request that patches get sent to openssl-dev. | |
6397 | [Richard Levitte] | |
6398 | ||
6399 | *) Add the VC-CE target, introduce the WINCE sysname, and add | |
6400 | INSTALL.WCE and appropriate conditionals to make it build. | |
6401 | [Steven Reddie <smr@essemer.com.au> via Richard Levitte] | |
6402 | ||
6403 | *) Change the DLL names for Cygwin to cygcrypto-x.y.z.dll and | |
6404 | cygssl-x.y.z.dll, where x, y and z are the major, minor and | |
6405 | edit numbers of the version. | |
6406 | [Corinna Vinschen <vinschen@redhat.com> and Richard Levitte] | |
6407 | ||

6409 | (BUF_strlcpy() and BUF_strlcat()). | |
6410 | [Ben Laurie (CHATS) and Richard Levitte] | |

6412 | *) Avoid using fixed-size buffers for one-line DNs. | |
6413 | [Ben Laurie (CHATS)] | |
6414 | ||

6416 | resizing buffers containing secrets, and use where appropriate. | |

6418 | ||
6419 | *) Avoid using fixed size buffers for configuration file location. | |

6432 | overflows. | |
6433 | [Ben Laurie (CHATS)] | |
6434 | ||
6435 | *) Don't cache truncated DNS entries in the local cache (this could | |
6436 | potentially lead to a spoofing attack). | |
6437 | [Ben Laurie (CHATS)] | |
6438 | ||
6439 | *) Fix various buffers to be large enough for hex/decimal | |
6440 | representations in a platform independent manner. | |
6441 | [Ben Laurie (CHATS)] | |
6442 | ||
6443 | *) Add CRYPTO_realloc_clean() to avoid information leakage when | |
6444 | resizing buffers containing secrets, and use where appropriate. | |
6445 | [Ben Laurie (CHATS)] | |
6446 | ||

6448 | indents. | |
6449 | [Ben Laurie (CHATS)] | |
6450 | ||
6451 | *) Convert sprintf()/BIO_puts() to BIO_printf(). | |

6455 | full. Fixed. | |
6456 | [Ben Laurie (CHATS)] | |
6457 | ||
6458 | *) Add assertions to prevent user-supplied crypto functions from | |
6459 | overflowing internal buffers by having large block sizes, etc. | |
6460 | [Ben Laurie (CHATS)] | |
6461 | ||

6488 | *) Protect against overlong session ID context length in an encoded | |
6489 | session object. Since these are local, this does not appear to be | |
6490 | exploitable. | |
6491 | [Ben Laurie (CHATS)] | |
6492 | ||
6493 | *) Change from security patch (see 0.9.6e below) that did not affect | |
6494 | the 0.9.6 release series: | |
6495 | ||
6496 | Remote buffer overflow in SSL3 protocol - an attacker could | |
6497 | supply an oversized master key in Kerberos-enabled versions. | |

6505 | [Michael Bell <michael.bell@rz.hu-berlin.de>, Steve Henson] | |

6507 | *) The "block size" for block ciphers in CFB and OFB mode should be 1. | |
6508 | [Steve Henson, reported by Yngve Nysaeter Pettersen <yngve@opera.com>] | |
6509 | ||
6510 | *) Make sure tests can be performed even if the corresponding algorithms | |
6511 | have been removed entirely. This was also the last step to make | |
6512 | OpenSSL compilable with DJGPP under all reasonable conditions. | |
6513 | [Richard Levitte, Doug Kaufman <dkaufman@rahul.net>] | |
6514 | ||
6515 | *) Add cipher selection rules COMPLEMENTOFALL and COMPLEMENTOFDEFAULT | |
6516 | to allow version independent disabling of normally unselected ciphers, | |
6517 | which may be activated as a side-effect of selecting a single cipher. | |
6518 | ||
6519 | (E.g., cipher list string "RSA" enables ciphersuites that are left | |
6520 | out of "ALL" because they do not provide symmetric encryption. | |
6521 | "RSA:!COMPLEMEMENTOFALL" avoids these unsafe ciphersuites.) | |
6522 | [Lutz Jaenicke, Bodo Moeller] | |
6523 | ||
6524 | *) Add appropriate support for separate platform-dependent build | |
6525 | directories. The recommended way to make a platform-dependent | |
6526 | build directory is the following (tested on Linux), maybe with | |
6527 | some local tweaks: | |
6528 | ||
6529 | # Place yourself outside of the OpenSSL source tree. In | |
6530 | # this example, the environment variable OPENSSL_SOURCE | |
6531 | # is assumed to contain the absolute OpenSSL source directory. | |
6532 | mkdir -p objtree/"`uname -s`-`uname -r`-`uname -m`" | |
6533 | cd objtree/"`uname -s`-`uname -r`-`uname -m`" | |
6534 | (cd $OPENSSL_SOURCE; find . -type f) | while read F; do | |
6535 | mkdir -p `dirname $F` | |
6536 | ln -s $OPENSSL_SOURCE/$F $F | |
6537 | done | |
6538 | ||
6539 | To be absolutely sure not to disturb the source tree, a "make clean" | |
6540 | is a good thing. If it isn't successful, don't worry about it, | |
6541 | it probably means the source directory is very clean. | |
6542 | [Richard Levitte] | |
6543 | ||
6544 | *) Make sure any ENGINE control commands make local copies of string | |
6545 | pointers passed to them whenever necessary. Otherwise it is possible | |
6546 | the caller may have overwritten (or deallocated) the original string | |
6547 | data when a later ENGINE operation tries to use the stored values. | |
6548 | [Götz Babin-Ebell <babinebell@trustcenter.de>] | |
6549 | ||
6550 | *) Improve diagnostics in file reading and command-line digests. | |
6551 | [Ben Laurie aided and abetted by Solar Designer <solar@openwall.com>] | |
6552 | ||
6553 | *) Add AES modes CFB and OFB to the object database. Correct an | |
6554 | error in AES-CFB decryption. | |
6555 | [Richard Levitte] | |
6556 | ||
6557 | *) Remove most calls to EVP_CIPHER_CTX_cleanup() in evp_enc.c, this | |
6558 | allows existing EVP_CIPHER_CTX structures to be reused after | |
6559 | calling EVP_*Final(). This behaviour is used by encryption | |
6560 | BIOs and some applications. This has the side effect that | |
6561 | applications must explicitly clean up cipher contexts with | |
6562 | EVP_CIPHER_CTX_cleanup() or they will leak memory. | |
6563 | [Steve Henson] | |
6564 | ||
6565 | *) Check the values of dna and dnb in bn_mul_recursive before calling | |
6566 | bn_mul_comba (a non zero value means the a or b arrays do not contain | |
6567 | n2 elements) and fallback to bn_mul_normal if either is not zero. | |
6568 | [Steve Henson] | |
6569 | ||
6570 | *) Fix escaping of non-ASCII characters when using the -subj option | |
6571 | of the "openssl req" command line tool. (Robert Joop <joop@fokus.gmd.de>) | |
6572 | [Lutz Jaenicke] | |
6573 | ||
6574 | *) Make object definitions compliant to LDAP (RFC2256): SN is the short | |
6575 | form for "surname", serialNumber has no short form. | |
6576 | Use "mail" as the short name for "rfc822Mailbox" according to RFC2798; | |
6577 | therefore remove "mail" short name for "internet 7". | |
6578 | The OID for unique identifiers in X509 certificates is | |
6579 | x500UniqueIdentifier, not uniqueIdentifier. | |
6580 | Some more OID additions. (Michael Bell <michael.bell@rz.hu-berlin.de>) | |
6581 | [Lutz Jaenicke] | |
6582 | ||
6583 | *) Add an "init" command to the ENGINE config module and auto initialize | |
6584 | ENGINEs. Without any "init" command the ENGINE will be initialized | |
6585 | after all ctrl commands have been executed on it. If init=1 the | |
6586 | ENGINE is initialized at that point (ctrls before that point are run | |
6587 | on the uninitialized ENGINE and after on the initialized one). If | |
6588 | init=0 then the ENGINE will not be initialized at all. | |
6589 | [Steve Henson] | |
6590 | ||
6591 | *) Fix the 'app_verify_callback' interface so that the user-defined | |
6592 | argument is actually passed to the callback: In the | |
6593 | SSL_CTX_set_cert_verify_callback() prototype, the callback | |
6594 | declaration has been changed from | |
6595 | int (*cb)() | |
6596 | into | |
6597 | int (*cb)(X509_STORE_CTX *,void *); | |
6598 | in ssl_verify_cert_chain (ssl/ssl_cert.c), the call | |
6599 | i=s->ctx->app_verify_callback(&ctx) | |
6600 | has been changed into | |
6601 | i=s->ctx->app_verify_callback(&ctx, s->ctx->app_verify_arg). | |
6602 | ||
6603 | To update applications using SSL_CTX_set_cert_verify_callback(), | |
6604 | a dummy argument can be added to their callback functions. | |
6605 | [D. K. Smetters <smetters@parc.xerox.com>] | |
6606 | ||
6607 | *) Added the '4758cca' ENGINE to support IBM 4758 cards. | |
6608 | [Maurice Gittens <maurice@gittens.nl>, touchups by Geoff Thorpe] | |
6609 | ||
6610 | *) Add and OPENSSL_LOAD_CONF define which will cause | |
6611 | OpenSSL_add_all_algorithms() to load the openssl.cnf config file. | |
6612 | This allows older applications to transparently support certain | |
6613 | OpenSSL features: such as crypto acceleration and dynamic ENGINE loading. | |
6614 | Two new functions OPENSSL_add_all_algorithms_noconf() which will never | |
6615 | load the config file and OPENSSL_add_all_algorithms_conf() which will | |
6616 | always load it have also been added. | |
6617 | [Steve Henson] | |
6618 | ||
6619 | *) Add the OFB, CFB and CTR (all with 128 bit feedback) to AES. | |
6620 | Adjust NIDs and EVP layer. | |
6621 | [Stephen Sprunk <stephen@sprunk.org> and Richard Levitte] | |
6622 | ||
6623 | *) Config modules support in openssl utility. | |
6624 | ||
6625 | Most commands now load modules from the config file, | |
6626 | though in a few (such as version) this isn't done | |
6627 | because it couldn't be used for anything. | |
6628 | ||
6629 | In the case of ca and req the config file used is | |
6630 | the same as the utility itself: that is the -config | |
6631 | command line option can be used to specify an | |
6632 | alternative file. | |
6633 | [Steve Henson] | |
6634 | ||
6635 | *) Move default behaviour from OPENSSL_config(). If appname is NULL | |
6636 | use "openssl_conf" if filename is NULL use default openssl config file. | |
6637 | [Steve Henson] | |
6638 | ||
6639 | *) Add an argument to OPENSSL_config() to allow the use of an alternative | |
6640 | config section name. Add a new flag to tolerate a missing config file | |
6641 | and move code to CONF_modules_load_file(). | |
6642 | [Steve Henson] | |
6643 | ||
6644 | *) Support for crypto accelerator cards from Accelerated Encryption | |
6645 | Processing, www.aep.ie. (Use engine 'aep') | |
6646 | The support was copied from 0.9.6c [engine] and adapted/corrected | |
6647 | to work with the new engine framework. | |
6648 | [AEP Inc. and Richard Levitte] | |
6649 | ||
6650 | *) Support for SureWare crypto accelerator cards from Baltimore | |
6651 | Technologies. (Use engine 'sureware') | |
6652 | The support was copied from 0.9.6c [engine] and adapted | |
6653 | to work with the new engine framework. | |
6654 | [Richard Levitte] | |
6655 | ||
6656 | *) Have the CHIL engine fork-safe (as defined by nCipher) and actually | |
6657 | make the newer ENGINE framework commands for the CHIL engine work. | |
6658 | [Toomas Kiisk <vix@cyber.ee> and Richard Levitte] | |

6661 | [Robert Dahlem <Robert.Dahlem@ffm2.siemens.de> via Richard Levitte] | |
6662 | ||
6663 | *) Add the configuration target debug-linux-ppro. | |
6664 | Make 'openssl rsa' use the general key loading routines | |
6665 | implemented in apps.c, and make those routines able to | |
6666 | handle the key format FORMAT_NETSCAPE and the variant | |
6667 | FORMAT_IISSGC. | |
6668 | [Toomas Kiisk <vix@cyber.ee> via Richard Levitte] | |

6671 | [Toomas Kiisk <vix@cyber.ee> via Richard Levitte] | |
6672 | ||
6673 | *) Add -keyform to rsautl, and document -engine. | |
6674 | [Richard Levitte, inspired by Toomas Kiisk <vix@cyber.ee>] | |
6675 | ||
6676 | *) Change BIO_new_file (crypto/bio/bss_file.c) to use new | |
6677 | BIO_R_NO_SUCH_FILE error code rather than the generic | |
6678 | ERR_R_SYS_LIB error code if fopen() fails with ENOENT. | |
6679 | [Ben Laurie] | |
6680 | ||
6681 | *) Add new functions | |
6682 | ERR_peek_last_error | |
6683 | ERR_peek_last_error_line | |
6684 | ERR_peek_last_error_line_data. | |
6685 | These are similar to | |
6686 | ERR_peek_error | |
6687 | ERR_peek_error_line | |
6688 | ERR_peek_error_line_data, | |
6689 | but report on the latest error recorded rather than the first one | |
6690 | still in the error queue. | |
6691 | [Ben Laurie, Bodo Moeller] | |
6692 | ||
6693 | *) default_algorithms option in ENGINE config module. This allows things | |
6694 | like: | |

6696 | default_algorithms = RSA, DSA, RAND, CIPHERS, DIGESTS | |
6697 | [Steve Henson] | |
6698 | ||
6699 | *) Preliminary ENGINE config module. | |
6700 | [Steve Henson] | |
6701 | ||
6702 | *) New experimental application configuration code. | |
6703 | [Steve Henson] | |
6704 | ||
6705 | *) Change the AES code to follow the same name structure as all other | |
6706 | symmetric ciphers, and behave the same way. Move everything to | |
6707 | the directory crypto/aes, thereby obsoleting crypto/rijndael. | |
6708 | [Stephen Sprunk <stephen@sprunk.org> and Richard Levitte] | |
6709 | ||
6710 | *) SECURITY: remove unsafe setjmp/signal interaction from ui_openssl.c. | |
6711 | [Ben Laurie and Theo de Raadt] | |
6712 | ||
6713 | *) Add option to output public keys in req command. | |
6714 | [Massimiliano Pala madwolf@openca.org] | |
6715 | ||
6716 | *) Use wNAFs in EC_POINTs_mul() for improved efficiency | |
6717 | (up to about 10% better than before for P-192 and P-224). | |
6718 | [Bodo Moeller] | |
6719 | ||
6720 | *) New functions/macros | |
6721 | ||
6722 | SSL_CTX_set_msg_callback(ctx, cb) | |
6723 | SSL_CTX_set_msg_callback_arg(ctx, arg) | |
6724 | SSL_set_msg_callback(ssl, cb) | |
6725 | SSL_set_msg_callback_arg(ssl, arg) | |
6726 | ||
6727 | to request calling a callback function | |
6728 | ||
6729 | void cb(int write_p, int version, int content_type, | |
6730 | const void *buf, size_t len, SSL *ssl, void *arg) | |
6731 | ||
6732 | whenever a protocol message has been completely received | |
6733 | (write_p == 0) or sent (write_p == 1). Here 'version' is the | |
6734 | protocol version according to which the SSL library interprets | |
6735 | the current protocol message (SSL2_VERSION, SSL3_VERSION, or | |
6736 | TLS1_VERSION). 'content_type' is 0 in the case of SSL 2.0, or | |
6737 | the content type as defined in the SSL 3.0/TLS 1.0 protocol | |
6738 | specification (change_cipher_spec(20), alert(21), handshake(22)). | |
6739 | 'buf' and 'len' point to the actual message, 'ssl' to the | |
6740 | SSL object, and 'arg' is the application-defined value set by | |
6741 | SSL[_CTX]_set_msg_callback_arg(). | |
6742 | ||
6743 | 'openssl s_client' and 'openssl s_server' have new '-msg' options | |
6744 | to enable a callback that displays all protocol messages. | |
6745 | [Bodo Moeller] | |
6746 | ||
6747 | *) Change the shared library support so shared libraries are built as | |
6748 | soon as the corresponding static library is finished, and thereby get | |
6749 | openssl and the test programs linked against the shared library. | |
6750 | This still only happens when the keyword "shard" has been given to | |
6751 | the configuration scripts. | |
6752 | ||
6753 | NOTE: shared library support is still an experimental thing, and | |
6754 | backward binary compatibility is still not guaranteed. | |
6755 | ["Maciej W. Rozycki" <macro@ds2.pg.gda.pl> and Richard Levitte] | |
6756 | ||
6757 | *) Add support for Subject Information Access extension. | |
6758 | [Peter Sylvester <Peter.Sylvester@EdelWeb.fr>] | |
6759 | ||
6760 | *) Make BUF_MEM_grow() behaviour more consistent: Initialise to zero | |
6761 | additional bytes when new memory had to be allocated, not just | |
6762 | when reusing an existing buffer. | |
6763 | [Bodo Moeller] | |
6764 | ||
6765 | *) New command line and configuration option 'utf8' for the req command. | |
6766 | This allows field values to be specified as UTF8 strings. | |
6767 | [Steve Henson] | |
6768 | ||
6769 | *) Add -multi and -mr options to "openssl speed" - giving multiple parallel | |
6770 | runs for the former and machine-readable output for the latter. | |
6771 | [Ben Laurie] | |
6772 | ||
6773 | *) Add '-noemailDN' option to 'openssl ca'. This prevents inclusion | |
6774 | of the e-mail address in the DN (i.e., it will go into a certificate | |
6775 | extension only). The new configuration file option 'email_in_dn = no' | |
6776 | has the same effect. | |
6777 | [Massimiliano Pala madwolf@openca.org] | |
6778 | ||
6779 | *) Change all functions with names starting with des_ to be starting | |
6780 | with DES_ instead. Add wrappers that are compatible with libdes, | |
6781 | but are named _ossl_old_des_*. Finally, add macros that map the | |
6782 | des_* symbols to the corresponding _ossl_old_des_* if libdes | |
6783 | compatibility is desired. If OpenSSL 0.9.6c compatibility is | |
6784 | desired, the des_* symbols will be mapped to DES_*, with one | |
6785 | exception. | |
6786 | ||
6787 | Since we provide two compatibility mappings, the user needs to | |
6788 | define the macro OPENSSL_DES_LIBDES_COMPATIBILITY if libdes | |
6789 | compatibility is desired. The default (i.e., when that macro | |
6790 | isn't defined) is OpenSSL 0.9.6c compatibility. | |
6791 | ||
6792 | There are also macros that enable and disable the support of old | |
6793 | des functions altogether. Those are OPENSSL_ENABLE_OLD_DES_SUPPORT | |
6794 | and OPENSSL_DISABLE_OLD_DES_SUPPORT. If none or both of those | |
6795 | are defined, the default will apply: to support the old des routines. | |
6796 | ||
6797 | In either case, one must include openssl/des.h to get the correct | |
6798 | definitions. Do not try to just include openssl/des_old.h, that | |
6799 | won't work. | |
6800 | ||
6801 | NOTE: This is a major break of an old API into a new one. Software | |
6802 | authors are encouraged to switch to the DES_ style functions. Some | |
6803 | time in the future, des_old.h and the libdes compatibility functions | |
6804 | will be disable (i.e. OPENSSL_DISABLE_OLD_DES_SUPPORT will be the | |
6805 | default), and then completely removed. | |
6806 | [Richard Levitte] | |
6807 | ||
6808 | *) Test for certificates which contain unsupported critical extensions. | |
6809 | If such a certificate is found during a verify operation it is | |
6810 | rejected by default: this behaviour can be overridden by either | |
6811 | handling the new error X509_V_ERR_UNHANDLED_CRITICAL_EXTENSION or | |
6812 | by setting the verify flag X509_V_FLAG_IGNORE_CRITICAL. A new function | |
6813 | X509_supported_extension() has also been added which returns 1 if a | |
6814 | particular extension is supported. | |
6815 | [Steve Henson] | |
6816 | ||
6817 | *) Modify the behaviour of EVP cipher functions in similar way to digests | |
6818 | to retain compatibility with existing code. | |
6819 | [Steve Henson] | |
6820 | ||
6821 | *) Modify the behaviour of EVP_DigestInit() and EVP_DigestFinal() to retain | |
6822 | compatibility with existing code. In particular the 'ctx' parameter does | |
6823 | not have to be to be initialized before the call to EVP_DigestInit() and | |
6824 | it is tidied up after a call to EVP_DigestFinal(). New function | |
6825 | EVP_DigestFinal_ex() which does not tidy up the ctx. Similarly function | |
6826 | EVP_MD_CTX_copy() changed to not require the destination to be | |
6827 | initialized valid and new function EVP_MD_CTX_copy_ex() added which | |
6828 | requires the destination to be valid. | |
6829 | ||
6830 | Modify all the OpenSSL digest calls to use EVP_DigestInit_ex(), | |
6831 | EVP_DigestFinal_ex() and EVP_MD_CTX_copy_ex(). | |
6832 | [Steve Henson] | |
6833 | ||
6834 | *) Change ssl3_get_message (ssl/s3_both.c) and the functions using it | |
6835 | so that complete 'Handshake' protocol structures are kept in memory | |
6836 | instead of overwriting 'msg_type' and 'length' with 'body' data. | |
6837 | [Bodo Moeller] | |
6838 | ||
6839 | *) Add an implementation of SSL_add_dir_cert_subjects_to_stack for Win32. | |
6840 | [Massimo Santin via Richard Levitte] | |
6841 | ||
6842 | *) Major restructuring to the underlying ENGINE code. This includes | |
6843 | reduction of linker bloat, separation of pure "ENGINE" manipulation | |
6844 | (initialisation, etc) from functionality dealing with implementations | |
6845 | of specific crypto interfaces. This change also introduces integrated | |
6846 | support for symmetric ciphers and digest implementations - so ENGINEs | |
6847 | can now accelerate these by providing EVP_CIPHER and EVP_MD | |
6848 | implementations of their own. This is detailed in crypto/engine/README | |
6849 | as it couldn't be adequately described here. However, there are a few | |
6850 | API changes worth noting - some RSA, DSA, DH, and RAND functions that | |
6851 | were changed in the original introduction of ENGINE code have now | |
6852 | reverted back - the hooking from this code to ENGINE is now a good | |
6853 | deal more passive and at run-time, operations deal directly with | |
6854 | RSA_METHODs, DSA_METHODs (etc) as they did before, rather than | |
6855 | dereferencing through an ENGINE pointer any more. Also, the ENGINE | |
6856 | functions dealing with BN_MOD_EXP[_CRT] handlers have been removed - | |
6857 | they were not being used by the framework as there is no concept of a | |
6858 | BIGNUM_METHOD and they could not be generalised to the new | |
6859 | 'ENGINE_TABLE' mechanism that underlies the new code. Similarly, | |
6860 | ENGINE_cpy() has been removed as it cannot be consistently defined in | |
6861 | the new code. | |
6862 | [Geoff Thorpe] | |
6863 | ||
6864 | *) Change ASN1_GENERALIZEDTIME_check() to allow fractional seconds. | |
6865 | [Steve Henson] | |
6866 | ||
6867 | *) Change mkdef.pl to sort symbols that get the same entry number, | |
6868 | and make sure the automatically generated functions ERR_load_* | |
6869 | become part of libeay.num as well. | |
6870 | [Richard Levitte] | |
6871 | ||
6872 | *) New function SSL_renegotiate_pending(). This returns true once | |
6873 | renegotiation has been requested (either SSL_renegotiate() call | |
6874 | or HelloRequest/ClientHello received from the peer) and becomes | |
6875 | false once a handshake has been completed. | |
6876 | (For servers, SSL_renegotiate() followed by SSL_do_handshake() | |
6877 | sends a HelloRequest, but does not ensure that a handshake takes | |
6878 | place. SSL_renegotiate_pending() is useful for checking if the | |
6879 | client has followed the request.) | |
6880 | [Bodo Moeller] | |
6881 | ||
6882 | *) New SSL option SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION. | |
6883 | By default, clients may request session resumption even during | |
6884 | renegotiation (if session ID contexts permit); with this option, | |
6885 | session resumption is possible only in the first handshake. | |
6886 | ||
6887 | SSL_OP_ALL is now 0x00000FFFL instead of 0x000FFFFFL. This makes | |
6888 | more bits available for options that should not be part of | |
6889 | SSL_OP_ALL (such as SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION). | |
6890 | [Bodo Moeller] | |
6891 | ||
6892 | *) Add some demos for certificate and certificate request creation. | |
6893 | [Steve Henson] | |
6894 | ||
6895 | *) Make maximum certificate chain size accepted from the peer application | |
6896 | settable (SSL*_get/set_max_cert_list()), as proposed by | |
6897 | "Douglas E. Engert" <deengert@anl.gov>. | |
6898 | [Lutz Jaenicke] | |
6899 | ||
6900 | *) Add support for shared libraries for Unixware-7 | |
6901 | (Boyd Lynn Gerber <gerberb@zenez.com>). | |
6902 | [Lutz Jaenicke] | |
6903 | ||
6904 | *) Add a "destroy" handler to ENGINEs that allows structural cleanup to | |
6905 | be done prior to destruction. Use this to unload error strings from | |
6906 | ENGINEs that load their own error strings. NB: This adds two new API | |
6907 | functions to "get" and "set" this destroy handler in an ENGINE. | |
6908 | [Geoff Thorpe] | |
6909 | ||
6910 | *) Alter all existing ENGINE implementations (except "openssl" and | |
6911 | "openbsd") to dynamically instantiate their own error strings. This | |
6912 | makes them more flexible to be built both as statically-linked ENGINEs | |
6913 | and self-contained shared-libraries loadable via the "dynamic" ENGINE. | |
6914 | Also, add stub code to each that makes building them as self-contained | |
6915 | shared-libraries easier (see README.ENGINE). | |
6916 | [Geoff Thorpe] | |
6917 | ||
6918 | *) Add a "dynamic" ENGINE that provides a mechanism for binding ENGINE | |
6919 | implementations into applications that are completely implemented in | |
6920 | self-contained shared-libraries. The "dynamic" ENGINE exposes control | |
6921 | commands that can be used to configure what shared-library to load and | |
6922 | to control aspects of the way it is handled. Also, made an update to | |
6923 | the README.ENGINE file that brings its information up-to-date and | |
6924 | provides some information and instructions on the "dynamic" ENGINE | |
6925 | (ie. how to use it, how to build "dynamic"-loadable ENGINEs, etc). | |
6926 | [Geoff Thorpe] | |
6927 | ||
6928 | *) Make it possible to unload ranges of ERR strings with a new | |
6929 | "ERR_unload_strings" function. | |
6930 | [Geoff Thorpe] | |
6931 | ||
6932 | *) Add a copy() function to EVP_MD. | |
6933 | [Ben Laurie] | |
6934 | ||
6935 | *) Make EVP_MD routines take a context pointer instead of just the | |
6936 | md_data void pointer. | |
6937 | [Ben Laurie] | |
6938 | ||
6939 | *) Add flags to EVP_MD and EVP_MD_CTX. EVP_MD_FLAG_ONESHOT indicates | |
6940 | that the digest can only process a single chunk of data | |
6941 | (typically because it is provided by a piece of | |
6942 | hardware). EVP_MD_CTX_FLAG_ONESHOT indicates that the application | |
6943 | is only going to provide a single chunk of data, and hence the | |
6944 | framework needn't accumulate the data for oneshot drivers. | |
6945 | [Ben Laurie] | |
6946 | ||
6947 | *) As with "ERR", make it possible to replace the underlying "ex_data" | |
6948 | functions. This change also alters the storage and management of global | |
6949 | ex_data state - it's now all inside ex_data.c and all "class" code (eg. | |
6950 | RSA, BIO, SSL_CTX, etc) no longer stores its own STACKS and per-class | |
6951 | index counters. The API functions that use this state have been changed | |
6952 | to take a "class_index" rather than pointers to the class's local STACK | |
6953 | and counter, and there is now an API function to dynamically create new | |
6954 | classes. This centralisation allows us to (a) plug a lot of the | |
6955 | thread-safety problems that existed, and (b) makes it possible to clean | |
6956 | up all allocated state using "CRYPTO_cleanup_all_ex_data()". W.r.t. (b) | |
6957 | such data would previously have always leaked in application code and | |
6958 | workarounds were in place to make the memory debugging turn a blind eye | |
6959 | to it. Application code that doesn't use this new function will still | |
6960 | leak as before, but their memory debugging output will announce it now | |
6961 | rather than letting it slide. | |
6962 | ||
6963 | Besides the addition of CRYPTO_cleanup_all_ex_data(), another API change | |
6964 | induced by the "ex_data" overhaul is that X509_STORE_CTX_init() now | |
6965 | has a return value to indicate success or failure. | |
6966 | [Geoff Thorpe] | |
6967 | ||
6968 | *) Make it possible to replace the underlying "ERR" functions such that the | |
6969 | global state (2 LHASH tables and 2 locks) is only used by the "default" | |
6970 | implementation. This change also adds two functions to "get" and "set" | |
6971 | the implementation prior to it being automatically set the first time | |
6972 | any other ERR function takes place. Ie. an application can call "get", | |
6973 | pass the return value to a module it has just loaded, and that module | |
6974 | can call its own "set" function using that value. This means the | |
6975 | module's "ERR" operations will use (and modify) the error state in the | |
6976 | application and not in its own statically linked copy of OpenSSL code. | |
6977 | [Geoff Thorpe] | |
6978 | ||
6979 | *) Give DH, DSA, and RSA types their own "**_up_ref()" function to increment | |
6980 | reference counts. This performs normal REF_PRINT/REF_CHECK macros on | |
6981 | the operation, and provides a more encapsulated way for external code | |
6982 | (crypto/evp/ and ssl/) to do this. Also changed the evp and ssl code | |
6983 | to use these functions rather than manually incrementing the counts. | |
6984 | ||
6985 | Also rename "DSO_up()" function to more descriptive "DSO_up_ref()". | |
6986 | [Geoff Thorpe] | |
6987 | ||
6988 | *) Add EVP test program. | |
6989 | [Ben Laurie] | |
6990 | ||
6991 | *) Add symmetric cipher support to ENGINE. Expect the API to change! | |
6992 | [Ben Laurie] | |
6993 | ||
6994 | *) New CRL functions: X509_CRL_set_version(), X509_CRL_set_issuer_name() | |
6995 | X509_CRL_set_lastUpdate(), X509_CRL_set_nextUpdate(), X509_CRL_sort(), | |
6996 | X509_REVOKED_set_serialNumber(), and X509_REVOKED_set_revocationDate(). | |
6997 | These allow a CRL to be built without having to access X509_CRL fields | |
6998 | directly. Modify 'ca' application to use new functions. | |
6999 | [Steve Henson] | |
7000 | ||
7001 | *) Move SSL_OP_TLS_ROLLBACK_BUG out of the SSL_OP_ALL list of recommended | |
7002 | bug workarounds. Rollback attack detection is a security feature. | |
7003 | The problem will only arise on OpenSSL servers when TLSv1 is not | |
7004 | available (sslv3_server_method() or SSL_OP_NO_TLSv1). | |
7005 | Software authors not wanting to support TLSv1 will have special reasons | |
7006 | for their choice and can explicitly enable this option. | |
7007 | [Bodo Moeller, Lutz Jaenicke] | |
7008 | ||
7009 | *) Rationalise EVP so it can be extended: don't include a union of | |
7010 | cipher/digest structures, add init/cleanup functions for EVP_MD_CTX | |
7011 | (similar to those existing for EVP_CIPHER_CTX). | |
7012 | Usage example: | |
7013 | ||
7014 | EVP_MD_CTX md; | |
7015 | ||
7016 | EVP_MD_CTX_init(&md); /* new function call */ | |
7017 | EVP_DigestInit(&md, EVP_sha1()); | |
7018 | EVP_DigestUpdate(&md, in, len); | |
7019 | EVP_DigestFinal(&md, out, NULL); | |
7020 | EVP_MD_CTX_cleanup(&md); /* new function call */ | |
7021 | ||
7022 | [Ben Laurie] | |
7023 | ||
7024 | *) Make DES key schedule conform to the usual scheme, as well as | |
7025 | correcting its structure. This means that calls to DES functions | |
7026 | now have to pass a pointer to a des_key_schedule instead of a | |
7027 | plain des_key_schedule (which was actually always a pointer | |
7028 | anyway): E.g., | |
7029 | ||
7030 | des_key_schedule ks; | |
7031 | ||
7032 | des_set_key_checked(..., &ks); | |
7033 | des_ncbc_encrypt(..., &ks, ...); | |
7034 | ||
7035 | (Note that a later change renames 'des_...' into 'DES_...'.) | |
7036 | [Ben Laurie] | |
7037 | ||
7038 | *) Initial reduction of linker bloat: the use of some functions, such as | |
7039 | PEM causes large amounts of unused functions to be linked in due to | |
7040 | poor organisation. For example pem_all.c contains every PEM function | |
7041 | which has a knock on effect of linking in large amounts of (unused) | |
7042 | ASN1 code. Grouping together similar functions and splitting unrelated | |
7043 | functions prevents this. | |
7044 | [Steve Henson] | |
7045 | ||
7046 | *) Cleanup of EVP macros. | |
7047 | [Ben Laurie] | |
7048 | ||
7049 | *) Change historical references to {NID,SN,LN}_des_ede and ede3 to add the | |
7050 | correct _ecb suffix. | |
7051 | [Ben Laurie] | |
7052 | ||
7053 | *) Add initial OCSP responder support to ocsp application. The | |
7054 | revocation information is handled using the text based index | |
7055 | use by the ca application. The responder can either handle | |
7056 | requests generated internally, supplied in files (for example | |
7057 | via a CGI script) or using an internal minimal server. | |
7058 | [Steve Henson] | |
7059 | ||
7060 | *) Add configuration choices to get zlib compression for TLS. | |
7061 | [Richard Levitte] | |
7062 | ||
7063 | *) Changes to Kerberos SSL for RFC 2712 compliance: | |
7064 | 1. Implemented real KerberosWrapper, instead of just using | |
7065 | KRB5 AP_REQ message. [Thanks to Simon Wilkinson <sxw@sxw.org.uk>] | |
7066 | 2. Implemented optional authenticator field of KerberosWrapper. | |
7067 | ||
7068 | Added openssl-style ASN.1 macros for Kerberos ticket, ap_req, | |
7069 | and authenticator structs; see crypto/krb5/. | |
7070 | ||
7071 | Generalized Kerberos calls to support multiple Kerberos libraries. | |
7072 | [Vern Staats <staatsvr@asc.hpc.mil>, | |
7073 | Jeffrey Altman <jaltman@columbia.edu> | |
7074 | via Richard Levitte] | |
7075 | ||
7076 | *) Cause 'openssl speed' to use fully hard-coded DSA keys as it | |
7077 | already does with RSA. testdsa.h now has 'priv_key/pub_key' | |
7078 | values for each of the key sizes rather than having just | |
7079 | parameters (and 'speed' generating keys each time). | |
7080 | [Geoff Thorpe] | |
7081 | ||
7082 | *) Speed up EVP routines. | |

7098 | [Ben Laurie] | |
7099 | ||
7100 | *) Added the OS2-EMX target. | |
7101 | ["Brian Havard" <brianh@kheldar.apana.org.au> and Richard Levitte] | |
7102 | ||
7103 | *) Rewrite apps to use NCONF routines instead of the old CONF. New functions | |
7104 | to support NCONF routines in extension code. New function CONF_set_nconf() | |
7105 | to allow functions which take an NCONF to also handle the old LHASH | |
7106 | structure: this means that the old CONF compatible routines can be | |
7107 | retained (in particular wrt extensions) without having to duplicate the | |
7108 | code. New function X509V3_add_ext_nconf_sk to add extensions to a stack. | |
7109 | [Steve Henson] | |
7110 | ||
7111 | *) Enhance the general user interface with mechanisms for inner control | |
7112 | and with possibilities to have yes/no kind of prompts. | |
7113 | [Richard Levitte] | |
7114 | ||
7115 | *) Change all calls to low level digest routines in the library and | |
7116 | applications to use EVP. Add missing calls to HMAC_cleanup() and | |
7117 | don't assume HMAC_CTX can be copied using memcpy(). | |
7118 | [Verdon Walker <VWalker@novell.com>, Steve Henson] | |
7119 | ||
7120 | *) Add the possibility to control engines through control names but with | |
7121 | arbitrary arguments instead of just a string. | |
7122 | Change the key loaders to take a UI_METHOD instead of a callback | |
7123 | function pointer. NOTE: this breaks binary compatibility with earlier | |
7124 | versions of OpenSSL [engine]. | |
7125 | Adapt the nCipher code for these new conditions and add a card insertion | |
7126 | callback. | |
7127 | [Richard Levitte] | |
7128 | ||
7129 | *) Enhance the general user interface with mechanisms to better support | |
7130 | dialog box interfaces, application-defined prompts, the possibility | |
7131 | to use defaults (for example default passwords from somewhere else) | |
7132 | and interrupts/cancellations. | |
7133 | [Richard Levitte] | |
7134 | ||
7135 | *) Tidy up PKCS#12 attribute handling. Add support for the CSP name | |
7136 | attribute in PKCS#12 files, add new -CSP option to pkcs12 utility. | |
7137 | [Steve Henson] | |
7138 | ||
7139 | *) Fix a memory leak in 'sk_dup()' in the case reallocation fails. (Also | |
7140 | tidy up some unnecessarily weird code in 'sk_new()'). | |
7141 | [Geoff, reported by Diego Tartara <dtartara@novamens.com>] | |
7142 | ||
7143 | *) Change the key loading routines for ENGINEs to use the same kind | |
7144 | callback (pem_password_cb) as all other routines that need this | |
7145 | kind of callback. | |
7146 | [Richard Levitte] | |
7147 | ||
7148 | *) Increase ENTROPY_NEEDED to 32 bytes, as Rijndael can operate with | |
7149 | 256 bit (=32 byte) keys. Of course seeding with more entropy bytes | |
7150 | than this minimum value is recommended. | |
7151 | [Lutz Jaenicke] | |
7152 | ||
7153 | *) New random seeder for OpenVMS, using the system process statistics | |
7154 | that are easily reachable. | |
7155 | [Richard Levitte] | |
7156 | ||
7157 | *) Windows apparently can't transparently handle global | |
7158 | variables defined in DLLs. Initialisations such as: | |
7159 | ||
7160 | const ASN1_ITEM *it = &ASN1_INTEGER_it; | |
7161 | ||
7162 | won't compile. This is used by the any applications that need to | |
7163 | declare their own ASN1 modules. This was fixed by adding the option | |
7164 | EXPORT_VAR_AS_FN to all Win32 platforms, although this isn't strictly | |
7165 | needed for static libraries under Win32. | |
7166 | [Steve Henson] | |
7167 | ||
7168 | *) New functions X509_PURPOSE_set() and X509_TRUST_set() to handle | |
7169 | setting of purpose and trust fields. New X509_STORE trust and | |
7170 | purpose functions and tidy up setting in other SSL functions. | |
7171 | [Steve Henson] | |
7172 | ||
7173 | *) Add copies of X509_STORE_CTX fields and callbacks to X509_STORE | |
7174 | structure. These are inherited by X509_STORE_CTX when it is | |
7175 | initialised. This allows various defaults to be set in the | |
7176 | X509_STORE structure (such as flags for CRL checking and custom | |
7177 | purpose or trust settings) for functions which only use X509_STORE_CTX | |
7178 | internally such as S/MIME. | |
7179 | ||
7180 | Modify X509_STORE_CTX_purpose_inherit() so it only sets purposes and | |
7181 | trust settings if they are not set in X509_STORE. This allows X509_STORE | |
7182 | purposes and trust (in S/MIME for example) to override any set by default. | |
7183 | ||
7184 | Add command line options for CRL checking to smime, s_client and s_server | |
7185 | applications. | |
7186 | [Steve Henson] | |
7187 | ||
7188 | *) Initial CRL based revocation checking. If the CRL checking flag(s) | |
7189 | are set then the CRL is looked up in the X509_STORE structure and | |
7190 | its validity and signature checked, then if the certificate is found | |
7191 | in the CRL the verify fails with a revoked error. | |
7192 | ||
7193 | Various new CRL related callbacks added to X509_STORE_CTX structure. | |
7194 | ||
7195 | Command line options added to 'verify' application to support this. | |
7196 | ||
7197 | This needs some additional work, such as being able to handle multiple | |
7198 | CRLs with different times, extension based lookup (rather than just | |
7199 | by subject name) and ultimately more complete V2 CRL extension | |
7200 | handling. | |
7201 | [Steve Henson] | |
7202 | ||
7203 | *) Add a general user interface API (crypto/ui/). This is designed | |
7204 | to replace things like des_read_password and friends (backward | |
7205 | compatibility functions using this new API are provided). | |
7206 | The purpose is to remove prompting functions from the DES code | |
7207 | section as well as provide for prompting through dialog boxes in | |
7208 | a window system and the like. | |
7209 | [Richard Levitte] | |
7210 | ||
7211 | *) Add "ex_data" support to ENGINE so implementations can add state at a | |
7212 | per-structure level rather than having to store it globally. | |
7213 | [Geoff] | |
7214 | ||
7215 | *) Make it possible for ENGINE structures to be copied when retrieved by | |
7216 | ENGINE_by_id() if the ENGINE specifies a new flag: ENGINE_FLAGS_BY_ID_COPY. | |
7217 | This causes the "original" ENGINE structure to act like a template, | |
7218 | analogous to the RSA vs. RSA_METHOD type of separation. Because of this | |
7219 | operational state can be localised to each ENGINE structure, despite the | |
7220 | fact they all share the same "methods". New ENGINE structures returned in | |
7221 | this case have no functional references and the return value is the single | |
7222 | structural reference. This matches the single structural reference returned | |
7223 | by ENGINE_by_id() normally, when it is incremented on the pre-existing | |
7224 | ENGINE structure. | |
7225 | [Geoff] | |
7226 | ||
7227 | *) Fix ASN1 decoder when decoding type ANY and V_ASN1_OTHER: since this | |
7228 | needs to match any other type at all we need to manually clear the | |
7229 | tag cache. | |
7230 | [Steve Henson] | |
7231 | ||
7232 | *) Changes to the "openssl engine" utility to include; | |
7233 | - verbosity levels ('-v', '-vv', and '-vvv') that provide information | |
7234 | about an ENGINE's available control commands. | |
7235 | - executing control commands from command line arguments using the | |
7236 | '-pre' and '-post' switches. '-post' is only used if '-t' is | |
7237 | specified and the ENGINE is successfully initialised. The syntax for | |
7238 | the individual commands are colon-separated, for example; | |
7239 | openssl engine chil -pre FORK_CHECK:0 -pre SO_PATH:/lib/test.so | |
7240 | [Geoff] | |
7241 | ||
7242 | *) New dynamic control command support for ENGINEs. ENGINEs can now | |
7243 | declare their own commands (numbers), names (strings), descriptions, | |
7244 | and input types for run-time discovery by calling applications. A | |
7245 | subset of these commands are implicitly classed as "executable" | |
7246 | depending on their input type, and only these can be invoked through | |
7247 | the new string-based API function ENGINE_ctrl_cmd_string(). (Eg. this | |
7248 | can be based on user input, config files, etc). The distinction is | |
7249 | that "executable" commands cannot return anything other than a boolean | |
7250 | result and can only support numeric or string input, whereas some | |
7251 | discoverable commands may only be for direct use through | |
7252 | ENGINE_ctrl(), eg. supporting the exchange of binary data, function | |
7253 | pointers, or other custom uses. The "executable" commands are to | |
7254 | support parameterisations of ENGINE behaviour that can be | |
7255 | unambiguously defined by ENGINEs and used consistently across any | |
7256 | OpenSSL-based application. Commands have been added to all the | |
7257 | existing hardware-supporting ENGINEs, noticeably "SO_PATH" to allow | |
7258 | control over shared-library paths without source code alterations. | |
7259 | [Geoff] | |
7260 | ||
7261 | *) Changed all ENGINE implementations to dynamically allocate their | |
7262 | ENGINEs rather than declaring them statically. Apart from this being | |
7263 | necessary with the removal of the ENGINE_FLAGS_MALLOCED distinction, | |
7264 | this also allows the implementations to compile without using the | |
7265 | internal engine_int.h header. | |
7266 | [Geoff] | |
7267 | ||
7268 | *) Minor adjustment to "rand" code. RAND_get_rand_method() now returns a | |
7269 | 'const' value. Any code that should be able to modify a RAND_METHOD | |
7270 | should already have non-const pointers to it (ie. they should only | |
7271 | modify their own ones). | |
7272 | [Geoff] | |
7273 | ||
7274 | *) Made a variety of little tweaks to the ENGINE code. | |
7275 | - "atalla" and "ubsec" string definitions were moved from header files | |
7276 | to C code. "nuron" string definitions were placed in variables | |
7277 | rather than hard-coded - allowing parameterisation of these values | |
7278 | later on via ctrl() commands. | |
7279 | - Removed unused "#if 0"'d code. | |
7280 | - Fixed engine list iteration code so it uses ENGINE_free() to release | |
7281 | structural references. | |
7282 | - Constified the RAND_METHOD element of ENGINE structures. | |
7283 | - Constified various get/set functions as appropriate and added | |
7284 | missing functions (including a catch-all ENGINE_cpy that duplicates | |
7285 | all ENGINE values onto a new ENGINE except reference counts/state). | |
7286 | - Removed NULL parameter checks in get/set functions. Setting a method | |
7287 | or function to NULL is a way of cancelling out a previously set | |
7288 | value. Passing a NULL ENGINE parameter is just plain stupid anyway | |
7289 | and doesn't justify the extra error symbols and code. | |
7290 | - Deprecate the ENGINE_FLAGS_MALLOCED define and move the area for | |
7291 | flags from engine_int.h to engine.h. | |
7292 | - Changed prototypes for ENGINE handler functions (init(), finish(), | |
7293 | ctrl(), key-load functions, etc) to take an (ENGINE*) parameter. | |
7294 | [Geoff] | |
7295 | ||
7296 | *) Implement binary inversion algorithm for BN_mod_inverse in addition | |
7297 | to the algorithm using long division. The binary algorithm can be | |
7298 | used only if the modulus is odd. On 32-bit systems, it is faster | |
7299 | only for relatively small moduli (roughly 20-30% for 128-bit moduli, | |
7300 | roughly 5-15% for 256-bit moduli), so we use it only for moduli | |
7301 | up to 450 bits. In 64-bit environments, the binary algorithm | |
7302 | appears to be advantageous for much longer moduli; here we use it | |
7303 | for moduli up to 2048 bits. | |
7304 | [Bodo Moeller] | |
7305 | ||
7306 | *) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code | |
7307 | could not support the combine flag in choice fields. | |
7308 | [Steve Henson] | |
7309 | ||
7310 | *) Add a 'copy_extensions' option to the 'ca' utility. This copies | |
7311 | extensions from a certificate request to the certificate. | |
7312 | [Steve Henson] | |
7313 | ||
7314 | *) Allow multiple 'certopt' and 'nameopt' options to be separated | |
7315 | by commas. Add 'namopt' and 'certopt' options to the 'ca' config | |
7316 | file: this allows the display of the certificate about to be | |
7317 | signed to be customised, to allow certain fields to be included | |
7318 | or excluded and extension details. The old system didn't display | |
7319 | multicharacter strings properly, omitted fields not in the policy | |
7320 | and couldn't display additional details such as extensions. | |
7321 | [Steve Henson] | |
7322 | ||
7323 | *) Function EC_POINTs_mul for multiple scalar multiplication | |
7324 | of an arbitrary number of elliptic curve points | |
7325 | \sum scalars[i]*points[i], | |
7326 | optionally including the generator defined for the EC_GROUP: | |
7327 | scalar*generator + \sum scalars[i]*points[i]. | |
7328 | ||
7329 | EC_POINT_mul is a simple wrapper function for the typical case | |
7330 | that the point list has just one item (besides the optional | |
7331 | generator). | |
7332 | [Bodo Moeller] | |
7333 | ||
7334 | *) First EC_METHODs for curves over GF(p): | |
7335 | ||
7336 | EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr | |
7337 | operations and provides various method functions that can also | |
7338 | operate with faster implementations of modular arithmetic. | |
7339 | ||
7340 | EC_GFp_mont_method() reuses most functions that are part of | |
7341 | EC_GFp_simple_method, but uses Montgomery arithmetic. | |
7342 | ||
7343 | [Bodo Moeller; point addition and point doubling | |
7344 | implementation directly derived from source code provided by | |
7345 | Lenka Fibikova <fibikova@exp-math.uni-essen.de>] | |
7346 | ||
7347 | *) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h, | |
7348 | crypto/ec/ec_lib.c): | |
7349 | ||
7350 | Curves are EC_GROUP objects (with an optional group generator) | |
7351 | based on EC_METHODs that are built into the library. | |
7352 | ||
7353 | Points are EC_POINT objects based on EC_GROUP objects. | |
7354 | ||
7355 | Most of the framework would be able to handle curves over arbitrary | |
7356 | finite fields, but as there are no obvious types for fields other | |
7357 | than GF(p), some functions are limited to that for now. | |
7358 | [Bodo Moeller] | |
7359 | ||
7360 | *) Add the -HTTP option to s_server. It is similar to -WWW, but requires | |
7361 | that the file contains a complete HTTP response. | |
7362 | [Richard Levitte] | |
7363 | ||
7364 | *) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl | |
7365 | change the def and num file printf format specifier from "%-40sXXX" | |
7366 | to "%-39s XXX". The latter will always guarantee a space after the | |
7367 | field while the former will cause them to run together if the field | |
7368 | is 40 of more characters long. | |
7369 | [Steve Henson] | |
7370 | ||
7371 | *) Constify the cipher and digest 'method' functions and structures | |
7372 | and modify related functions to take constant EVP_MD and EVP_CIPHER | |
7373 | pointers. | |
7374 | [Steve Henson] | |
7375 | ||
7376 | *) Hide BN_CTX structure details in bn_lcl.h instead of publishing them | |
7377 | in <openssl/bn.h>. Also further increase BN_CTX_NUM to 32. | |
7378 | [Bodo Moeller] | |
7379 | ||
7380 | *) Modify EVP_Digest*() routines so they now return values. Although the | |
7381 | internal software routines can never fail additional hardware versions | |
7382 | might. | |
7383 | [Steve Henson] | |
7384 | ||
7385 | *) Clean up crypto/err/err.h and change some error codes to avoid conflicts: | |
7386 | ||
7387 | Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7 | |
7388 | (= ERR_R_PKCS7_LIB); it is now 64 instead of 32. | |
7389 | ||
7390 | ASN1 error codes | |
7391 | ERR_R_NESTED_ASN1_ERROR | |
7392 | ... | |
7393 | ERR_R_MISSING_ASN1_EOS | |
7394 | were 4 .. 9, conflicting with | |
7395 | ERR_LIB_RSA (= ERR_R_RSA_LIB) | |
7396 | ... | |
7397 | ERR_LIB_PEM (= ERR_R_PEM_LIB). | |
7398 | They are now 58 .. 63 (i.e., just below ERR_R_FATAL). | |
7399 | ||
7400 | Add new error code 'ERR_R_INTERNAL_ERROR'. | |
7401 | [Bodo Moeller] | |
7402 | ||
7403 | *) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock | |
7404 | suffices. | |
7405 | [Bodo Moeller] | |
7406 | ||
7407 | *) New option '-subj arg' for 'openssl req' and 'openssl ca'. This | |
7408 | sets the subject name for a new request or supersedes the | |
7409 | subject name in a given request. Formats that can be parsed are | |
7410 | 'CN=Some Name, OU=myOU, C=IT' | |
7411 | and | |
7412 | 'CN=Some Name/OU=myOU/C=IT'. | |
7413 | ||
7414 | Add options '-batch' and '-verbose' to 'openssl req'. | |
7415 | [Massimiliano Pala <madwolf@hackmasters.net>] | |
7416 | ||
7417 | *) Introduce the possibility to access global variables through | |
7418 | functions on platform were that's the best way to handle exporting | |
7419 | global variables in shared libraries. To enable this functionality, | |
7420 | one must configure with "EXPORT_VAR_AS_FN" or defined the C macro | |
7421 | "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter | |
7422 | is normally done by Configure or something similar). | |
7423 | ||
7424 | To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL | |
7425 | in the source file (foo.c) like this: | |
7426 | ||
7427 | OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1; | |
7428 | OPENSSL_IMPLEMENT_GLOBAL(double,bar); | |
7429 | ||
7430 | To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL | |
7431 | and OPENSSL_GLOBAL_REF in the header file (foo.h) like this: | |
7432 | ||
7433 | OPENSSL_DECLARE_GLOBAL(int,foo); | |
7434 | #define foo OPENSSL_GLOBAL_REF(foo) | |
7435 | OPENSSL_DECLARE_GLOBAL(double,bar); | |
7436 | #define bar OPENSSL_GLOBAL_REF(bar) | |
7437 | ||
7438 | The #defines are very important, and therefore so is including the | |
7439 | header file everywhere where the defined globals are used. | |
7440 | ||
7441 | The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition | |
7442 | of ASN.1 items, but that structure is a bit different. | |
7443 | ||
7444 | The largest change is in util/mkdef.pl which has been enhanced with | |
7445 | better and easier to understand logic to choose which symbols should | |
7446 | go into the Windows .def files as well as a number of fixes and code | |
7447 | cleanup (among others, algorithm keywords are now sorted | |
7448 | lexicographically to avoid constant rewrites). | |
7449 | [Richard Levitte] | |
7450 | ||
7451 | *) In BN_div() keep a copy of the sign of 'num' before writing the | |
7452 | result to 'rm' because if rm==num the value will be overwritten | |
7453 | and produce the wrong result if 'num' is negative: this caused | |
7454 | problems with BN_mod() and BN_nnmod(). | |
7455 | [Steve Henson] | |
7456 | ||
7457 | *) Function OCSP_request_verify(). This checks the signature on an | |
7458 | OCSP request and verifies the signer certificate. The signer | |
7459 | certificate is just checked for a generic purpose and OCSP request | |
7460 | trust settings. | |
7461 | [Steve Henson] | |
7462 | ||
7463 | *) Add OCSP_check_validity() function to check the validity of OCSP | |
7464 | responses. OCSP responses are prepared in real time and may only | |
7465 | be a few seconds old. Simply checking that the current time lies | |
7466 | between thisUpdate and nextUpdate max reject otherwise valid responses | |
7467 | caused by either OCSP responder or client clock inaccuracy. Instead | |
7468 | we allow thisUpdate and nextUpdate to fall within a certain period of | |
7469 | the current time. The age of the response can also optionally be | |
7470 | checked. Two new options -validity_period and -status_age added to | |
7471 | ocsp utility. | |
7472 | [Steve Henson] | |
7473 | ||
7474 | *) If signature or public key algorithm is unrecognized print out its | |
7475 | OID rather that just UNKNOWN. | |
7476 | [Steve Henson] | |
7477 | ||
7478 | *) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and | |
7479 | OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate | |
7480 | ID to be generated from the issuer certificate alone which can then be | |
7481 | passed to OCSP_id_issuer_cmp(). | |
7482 | [Steve Henson] | |
7483 | ||
7484 | *) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new | |
7485 | ASN1 modules to export functions returning ASN1_ITEM pointers | |
7486 | instead of the ASN1_ITEM structures themselves. This adds several | |
7487 | new macros which allow the underlying ASN1 function/structure to | |
7488 | be accessed transparently. As a result code should not use ASN1_ITEM | |
7489 | references directly (such as &X509_it) but instead use the relevant | |
7490 | macros (such as ASN1_ITEM_rptr(X509)). This option is to allow | |
7491 | use of the new ASN1 code on platforms where exporting structures | |
7492 | is problematical (for example in shared libraries) but exporting | |
7493 | functions returning pointers to structures is not. | |
7494 | [Steve Henson] | |
7495 | ||
7496 | *) Add support for overriding the generation of SSL/TLS session IDs. | |
7497 | These callbacks can be registered either in an SSL_CTX or per SSL. | |
7498 | The purpose of this is to allow applications to control, if they wish, | |
7499 | the arbitrary values chosen for use as session IDs, particularly as it | |
7500 | can be useful for session caching in multiple-server environments. A | |
7501 | command-line switch for testing this (and any client code that wishes | |
7502 | to use such a feature) has been added to "s_server". | |
7503 | [Geoff Thorpe, Lutz Jaenicke] | |
7504 | ||
7505 | *) Modify mkdef.pl to recognise and parse preprocessor conditionals | |
7506 | of the form '#if defined(...) || defined(...) || ...' and | |
7507 | '#if !defined(...) && !defined(...) && ...'. This also avoids | |
7508 | the growing number of special cases it was previously handling. | |
7509 | [Richard Levitte] | |
7510 | ||
7511 | *) Make all configuration macros available for application by making | |
7512 | sure they are available in opensslconf.h, by giving them names starting | |
7513 | with "OPENSSL_" to avoid conflicts with other packages and by making | |
7514 | sure e_os2.h will cover all platform-specific cases together with | |
7515 | opensslconf.h. | |
7516 | Additionally, it is now possible to define configuration/platform- | |
7517 | specific names (called "system identities"). In the C code, these | |
7518 | are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another | |
7519 | macro with the name beginning with "OPENSSL_SYS_", which is determined | |
7520 | from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on | |
7521 | what is available. | |
7522 | [Richard Levitte] | |
7523 | ||
7524 | *) New option -set_serial to 'req' and 'x509' this allows the serial | |
7525 | number to use to be specified on the command line. Previously self | |
7526 | signed certificates were hard coded with serial number 0 and the | |
7527 | CA options of 'x509' had to use a serial number in a file which was | |
7528 | auto incremented. | |
7529 | [Steve Henson] | |
7530 | ||
7531 | *) New options to 'ca' utility to support V2 CRL entry extensions. | |
7532 | Currently CRL reason, invalidity date and hold instruction are | |
7533 | supported. Add new CRL extensions to V3 code and some new objects. | |
7534 | [Steve Henson] | |
7535 | ||
7536 | *) New function EVP_CIPHER_CTX_set_padding() this is used to | |
7537 | disable standard block padding (aka PKCS#5 padding) in the EVP | |
7538 | API, which was previously mandatory. This means that the data is | |
7539 | not padded in any way and so the total length much be a multiple | |
7540 | of the block size, otherwise an error occurs. | |
7541 | [Steve Henson] | |
7542 | ||
7543 | *) Initial (incomplete) OCSP SSL support. | |
7544 | [Steve Henson] | |
7545 | ||
7546 | *) New function OCSP_parse_url(). This splits up a URL into its host, | |
7547 | port and path components: primarily to parse OCSP URLs. New -url | |
7548 | option to ocsp utility. | |
7549 | [Steve Henson] | |
7550 | ||
7551 | *) New nonce behavior. The return value of OCSP_check_nonce() now | |
7552 | reflects the various checks performed. Applications can decide | |
7553 | whether to tolerate certain situations such as an absent nonce | |
7554 | in a response when one was present in a request: the ocsp application | |
7555 | just prints out a warning. New function OCSP_add1_basic_nonce() | |
7556 | this is to allow responders to include a nonce in a response even if | |
7557 | the request is nonce-less. | |
7558 | [Steve Henson] | |
7559 | ||
7560 | *) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are | |
7561 | skipped when using openssl x509 multiple times on a single input file, | |
7562 | e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs". | |
7563 | [Bodo Moeller] | |
7564 | ||
7565 | *) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string() | |
7566 | set string type: to handle setting ASN1_TIME structures. Fix ca | |
7567 | utility to correctly initialize revocation date of CRLs. | |
7568 | [Steve Henson] | |
7569 | ||
7570 | *) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override | |
7571 | the clients preferred ciphersuites and rather use its own preferences. | |
7572 | Should help to work around M$ SGC (Server Gated Cryptography) bug in | |
7573 | Internet Explorer by ensuring unchanged hash method during stepup. | |
7574 | (Also replaces the broken/deactivated SSL_OP_NON_EXPORT_FIRST option.) | |
7575 | [Lutz Jaenicke] | |
7576 | ||
7577 | *) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael | |
7578 | to aes and add a new 'exist' option to print out symbols that don't | |
7579 | appear to exist. | |
7580 | [Steve Henson] | |
7581 | ||
7582 | *) Additional options to ocsp utility to allow flags to be set and | |
7583 | additional certificates supplied. | |
7584 | [Steve Henson] | |
7585 | ||
7586 | *) Add the option -VAfile to 'openssl ocsp', so the user can give the | |
7587 | OCSP client a number of certificate to only verify the response | |
7588 | signature against. | |
7589 | [Richard Levitte] | |
7590 | ||
7591 | *) Update Rijndael code to version 3.0 and change EVP AES ciphers to | |
7592 | handle the new API. Currently only ECB, CBC modes supported. Add new | |
7593 | AES OIDs. | |
7594 | ||
7595 | Add TLS AES ciphersuites as described in RFC3268, "Advanced | |
7596 | Encryption Standard (AES) Ciphersuites for Transport Layer | |
7597 | Security (TLS)". (In beta versions of OpenSSL 0.9.7, these were | |
7598 | not enabled by default and were not part of the "ALL" ciphersuite | |
7599 | alias because they were not yet official; they could be | |
7600 | explicitly requested by specifying the "AESdraft" ciphersuite | |
7601 | group alias. In the final release of OpenSSL 0.9.7, the group | |
7602 | alias is called "AES" and is part of "ALL".) | |
7603 | [Ben Laurie, Steve Henson, Bodo Moeller] | |
7604 | ||
7605 | *) New function OCSP_copy_nonce() to copy nonce value (if present) from | |
7606 | request to response. | |
7607 | [Steve Henson] | |
7608 | ||
7609 | *) Functions for OCSP responders. OCSP_request_onereq_count(), | |
7610 | OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info() | |
7611 | extract information from a certificate request. OCSP_response_create() | |
7612 | creates a response and optionally adds a basic response structure. | |
7613 | OCSP_basic_add1_status() adds a complete single response to a basic | |
7614 | response and returns the OCSP_SINGLERESP structure just added (to allow | |
7615 | extensions to be included for example). OCSP_basic_add1_cert() adds a | |
7616 | certificate to a basic response and OCSP_basic_sign() signs a basic | |
7617 | response with various flags. New helper functions ASN1_TIME_check() | |
7618 | (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime() | |
7619 | (converts ASN1_TIME to GeneralizedTime). | |
7620 | [Steve Henson] | |
7621 | ||
7622 | *) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}() | |
7623 | in a single operation. X509_get0_pubkey_bitstr() extracts the public_key | |
7624 | structure from a certificate. X509_pubkey_digest() digests the public_key | |
7625 | contents: this is used in various key identifiers. | |
7626 | [Steve Henson] | |
7627 | ||
7628 | *) Make sk_sort() tolerate a NULL argument. | |
7629 | [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>] | |
7630 | ||
7631 | *) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates | |
7632 | passed by the function are trusted implicitly. If any of them signed the | |
7633 | response then it is assumed to be valid and is not verified. | |
7634 | [Steve Henson] | |
7635 | ||
7636 | *) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT | |
7637 | to data. This was previously part of the PKCS7 ASN1 code. This | |
7638 | was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures. | |
7639 | [Steve Henson, reported by Kenneth R. Robinette | |
7640 | <support@securenetterm.com>] | |
7641 | ||
7642 | *) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1 | |
7643 | routines: without these tracing memory leaks is very painful. | |
7644 | Fix leaks in PKCS12 and PKCS7 routines. | |
7645 | [Steve Henson] | |
7646 | ||
7647 | *) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new(). | |
7648 | Previously it initialised the 'type' argument to V_ASN1_UTCTIME which | |
7649 | effectively meant GeneralizedTime would never be used. Now it | |
7650 | is initialised to -1 but X509_time_adj() now has to check the value | |
7651 | and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or | |
7652 | V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime. | |
7653 | [Steve Henson, reported by Kenneth R. Robinette | |
7654 | <support@securenetterm.com>] | |
7655 | ||
7656 | *) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously | |
7657 | result in a zero length in the ASN1_INTEGER structure which was | |
7658 | not consistent with the structure when d2i_ASN1_INTEGER() was used | |
7659 | and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER() | |
7660 | to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER() | |
7661 | where it did not print out a minus for negative ASN1_INTEGER. | |
7662 | [Steve Henson] | |
7663 | ||
7664 | *) Add summary printout to ocsp utility. The various functions which | |
7665 | convert status values to strings have been renamed to: | |
7666 | OCSP_response_status_str(), OCSP_cert_status_str() and | |
7667 | OCSP_crl_reason_str() and are no longer static. New options | |
7668 | to verify nonce values and to disable verification. OCSP response | |
7669 | printout format cleaned up. | |
7670 | [Steve Henson] | |
7671 | ||
7672 | *) Add additional OCSP certificate checks. These are those specified | |
7673 | in RFC2560. This consists of two separate checks: the CA of the | |
7674 | certificate being checked must either be the OCSP signer certificate | |
7675 | or the issuer of the OCSP signer certificate. In the latter case the | |
7676 | OCSP signer certificate must contain the OCSP signing extended key | |
7677 | usage. This check is performed by attempting to match the OCSP | |
7678 | signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash | |
7679 | in the OCSP_CERTID structures of the response. | |
7680 | [Steve Henson] | |
7681 | ||
7682 | *) Initial OCSP certificate verification added to OCSP_basic_verify() | |
7683 | and related routines. This uses the standard OpenSSL certificate | |
7684 | verify routines to perform initial checks (just CA validity) and | |
7685 | to obtain the certificate chain. Then additional checks will be | |
7686 | performed on the chain. Currently the root CA is checked to see | |
7687 | if it is explicitly trusted for OCSP signing. This is used to set | |
7688 | a root CA as a global signing root: that is any certificate that | |
7689 | chains to that CA is an acceptable OCSP signing certificate. | |
7690 | [Steve Henson] | |
7691 | ||
7692 | *) New '-extfile ...' option to 'openssl ca' for reading X.509v3 | |
7693 | extensions from a separate configuration file. | |
7694 | As when reading extensions from the main configuration file, | |
7695 | the '-extensions ...' option may be used for specifying the | |
7696 | section to use. | |
7697 | [Massimiliano Pala <madwolf@comune.modena.it>] | |
7698 | ||
7699 | *) New OCSP utility. Allows OCSP requests to be generated or | |
7700 | read. The request can be sent to a responder and the output | |
7701 | parsed, outputed or printed in text form. Not complete yet: | |
7702 | still needs to check the OCSP response validity. | |
7703 | [Steve Henson] | |
7704 | ||
7705 | *) New subcommands for 'openssl ca': | |
7706 | 'openssl ca -status <serial>' prints the status of the cert with | |
7707 | the given serial number (according to the index file). | |
7708 | 'openssl ca -updatedb' updates the expiry status of certificates | |
7709 | in the index file. | |
7710 | [Massimiliano Pala <madwolf@comune.modena.it>] | |
7711 | ||
7712 | *) New '-newreq-nodes' command option to CA.pl. This is like | |
7713 | '-newreq', but calls 'openssl req' with the '-nodes' option | |
7714 | so that the resulting key is not encrypted. | |
7715 | [Damien Miller <djm@mindrot.org>] | |
7716 | ||
7717 | *) New configuration for the GNU Hurd. | |
7718 | [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte] | |
7719 | ||
7720 | *) Initial code to implement OCSP basic response verify. This | |
7721 | is currently incomplete. Currently just finds the signer's | |
7722 | certificate and verifies the signature on the response. | |
7723 | [Steve Henson] | |
7724 | ||
7725 | *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in | |
7726 | value of OPENSSLDIR. This is available via the new '-d' option | |
7727 | to 'openssl version', and is also included in 'openssl version -a'. | |
7728 | [Bodo Moeller] | |
7729 | ||
7730 | *) Allowing defining memory allocation callbacks that will be given | |
7731 | file name and line number information in additional arguments | |
7732 | (a const char* and an int). The basic functionality remains, as | |
7733 | well as the original possibility to just replace malloc(), | |
7734 | realloc() and free() by functions that do not know about these | |
7735 | additional arguments. To register and find out the current | |
7736 | settings for extended allocation functions, the following | |
7737 | functions are provided: | |
7738 | ||
7739 | CRYPTO_set_mem_ex_functions | |
7740 | CRYPTO_set_locked_mem_ex_functions | |
7741 | CRYPTO_get_mem_ex_functions | |
7742 | CRYPTO_get_locked_mem_ex_functions | |
7743 | ||
7744 | These work the same way as CRYPTO_set_mem_functions and friends. | |
7745 | CRYPTO_get_[locked_]mem_functions now writes 0 where such an | |
7746 | extended allocation function is enabled. | |
7747 | Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where | |
7748 | a conventional allocation function is enabled. | |
7749 | [Richard Levitte, Bodo Moeller] | |
7750 | ||
7751 | *) Finish off removing the remaining LHASH function pointer casts. | |
7752 | There should no longer be any prototype-casting required when using | |
7753 | the LHASH abstraction, and any casts that remain are "bugs". See | |
7754 | the callback types and macros at the head of lhash.h for details | |
7755 | (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example). | |
7756 | [Geoff Thorpe] | |
7757 | ||
7758 | *) Add automatic query of EGD sockets in RAND_poll() for the unix variant. | |
7759 | If /dev/[u]random devices are not available or do not return enough | |
7760 | entropy, EGD style sockets (served by EGD or PRNGD) will automatically | |
7761 | be queried. | |
7762 | The locations /var/run/egd-pool, /dev/egd-pool, /etc/egd-pool, and | |
7763 | /etc/entropy will be queried once each in this sequence, querying stops | |
7764 | when enough entropy was collected without querying more sockets. | |
7765 | [Lutz Jaenicke] | |
7766 | ||
7767 | *) Change the Unix RAND_poll() variant to be able to poll several | |
7768 | random devices, as specified by DEVRANDOM, until a sufficient amount | |
7769 | of data has been collected. We spend at most 10 ms on each file | |
7770 | (select timeout) and read in non-blocking mode. DEVRANDOM now | |
7771 | defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom" | |
7772 | (previously it was just the string "/dev/urandom"), so on typical | |
7773 | platforms the 10 ms delay will never occur. | |
7774 | Also separate out the Unix variant to its own file, rand_unix.c. | |
7775 | For VMS, there's a currently-empty rand_vms.c. | |
7776 | [Richard Levitte] | |
7777 | ||
7778 | *) Move OCSP client related routines to ocsp_cl.c. These | |
7779 | provide utility functions which an application needing | |
7780 | to issue a request to an OCSP responder and analyse the | |
7781 | response will typically need: as opposed to those which an | |
7782 | OCSP responder itself would need which will be added later. | |
7783 | ||
7784 | OCSP_request_sign() signs an OCSP request with an API similar | |
7785 | to PKCS7_sign(). OCSP_response_status() returns status of OCSP | |
7786 | response. OCSP_response_get1_basic() extracts basic response | |
7787 | from response. OCSP_resp_find_status(): finds and extracts status | |
7788 | information from an OCSP_CERTID structure (which will be created | |
7789 | when the request structure is built). These are built from lower | |
7790 | level functions which work on OCSP_SINGLERESP structures but | |
7791 | won't normally be used unless the application wishes to examine | |
7792 | extensions in the OCSP response for example. | |
7793 | ||
7794 | Replace nonce routines with a pair of functions. | |
7795 | OCSP_request_add1_nonce() adds a nonce value and optionally | |
7796 | generates a random value. OCSP_check_nonce() checks the | |
7797 | validity of the nonce in an OCSP response. | |
7798 | [Steve Henson] | |
7799 | ||
7800 | *) Change function OCSP_request_add() to OCSP_request_add0_id(). | |
7801 | This doesn't copy the supplied OCSP_CERTID and avoids the | |
7802 | need to free up the newly created id. Change return type | |
7803 | to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure. | |
7804 | This can then be used to add extensions to the request. | |
7805 | Deleted OCSP_request_new(), since most of its functionality | |
7806 | is now in OCSP_REQUEST_new() (and the case insensitive name | |
7807 | clash) apart from the ability to set the request name which | |
7808 | will be added elsewhere. | |
7809 | [Steve Henson] | |
7810 | ||
7811 | *) Update OCSP API. Remove obsolete extensions argument from | |
7812 | various functions. Extensions are now handled using the new | |
7813 | OCSP extension code. New simple OCSP HTTP function which | |
7814 | can be used to send requests and parse the response. | |
7815 | [Steve Henson] | |
7816 | ||
7817 | *) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new | |
7818 | ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN | |
7819 | uses the special reorder version of SET OF to sort the attributes | |
7820 | and reorder them to match the encoded order. This resolves a long | |
7821 | standing problem: a verify on a PKCS7 structure just after signing | |
7822 | it used to fail because the attribute order did not match the | |
7823 | encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes: | |
7824 | it uses the received order. This is necessary to tolerate some broken | |
7825 | software that does not order SET OF. This is handled by encoding | |
7826 | as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class) | |
7827 | to produce the required SET OF. | |
7828 | [Steve Henson] | |
7829 | ||
7830 | *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and | |
7831 | OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header | |
7832 | files to get correct declarations of the ASN.1 item variables. | |
7833 | [Richard Levitte] | |
7834 | ||
7835 | *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many | |
7836 | PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs: | |
7837 | asn1_check_tlen() would sometimes attempt to use 'ctx' when it was | |
7838 | NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i(). | |
7839 | New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant | |
7840 | ASN1_ITEM and no wrapper functions. | |
7841 | [Steve Henson] | |
7842 | ||
7843 | *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These | |
7844 | replace the old function pointer based I/O routines. Change most of | |
7845 | the *_d2i_bio() and *_d2i_fp() functions to use these. | |
7846 | [Steve Henson] | |
7847 | ||
7848 | *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor | |
7849 | lines, recognize more "algorithms" that can be deselected, and make | |
7850 | it complain about algorithm deselection that isn't recognised. | |
7851 | [Richard Levitte] | |
7852 | ||
7853 | *) New ASN1 functions to handle dup, sign, verify, digest, pack and | |
7854 | unpack operations in terms of ASN1_ITEM. Modify existing wrappers | |
7855 | to use new functions. Add NO_ASN1_OLD which can be set to remove | |
7856 | some old style ASN1 functions: this can be used to determine if old | |
7857 | code will still work when these eventually go away. | |
7858 | [Steve Henson] | |
7859 | ||
7860 | *) New extension functions for OCSP structures, these follow the | |
7861 | same conventions as certificates and CRLs. | |
7862 | [Steve Henson] | |
7863 | ||
7864 | *) New function X509V3_add1_i2d(). This automatically encodes and | |
7865 | adds an extension. Its behaviour can be customised with various | |
7866 | flags to append, replace or delete. Various wrappers added for | |
7867 | certificates and CRLs. | |
7868 | [Steve Henson] | |
7869 | ||
7870 | *) Fix to avoid calling the underlying ASN1 print routine when | |
7871 | an extension cannot be parsed. Correct a typo in the | |
7872 | OCSP_SERVICELOC extension. Tidy up print OCSP format. | |
7873 | [Steve Henson] | |
7874 | ||
7875 | *) Make mkdef.pl parse some of the ASN1 macros and add appropriate | |
7876 | entries for variables. | |
7877 | [Steve Henson] | |
7878 | ||
7879 | *) Add functionality to apps/openssl.c for detecting locking | |
7880 | problems: As the program is single-threaded, all we have | |
7881 | to do is register a locking callback using an array for | |
7882 | storing which locks are currently held by the program. | |
7883 | [Bodo Moeller] | |
7884 | ||
7885 | *) Use a lock around the call to CRYPTO_get_ex_new_index() in | |
7886 | SSL_get_ex_data_X509_STORE_idx(), which is used in | |
7887 | ssl_verify_cert_chain() and thus can be called at any time | |
7888 | during TLS/SSL handshakes so that thread-safety is essential. | |
7889 | Unfortunately, the ex_data design is not at all suited | |
7890 | for multi-threaded use, so it probably should be abolished. | |
7891 | [Bodo Moeller] | |
7892 | ||
7893 | *) Added Broadcom "ubsec" ENGINE to OpenSSL. | |
7894 | [Broadcom, tweaked and integrated by Geoff Thorpe] | |
7895 | ||
7896 | *) Move common extension printing code to new function | |
7897 | X509V3_print_extensions(). Reorganise OCSP print routines and | |
7898 | implement some needed OCSP ASN1 functions. Add OCSP extensions. | |
7899 | [Steve Henson] | |
7900 | ||
7901 | *) New function X509_signature_print() to remove duplication in some | |
7902 | print routines. | |
7903 | [Steve Henson] | |
7904 | ||
7905 | *) Add a special meaning when SET OF and SEQUENCE OF flags are both | |
7906 | set (this was treated exactly the same as SET OF previously). This | |
7907 | is used to reorder the STACK representing the structure to match the | |
7908 | encoding. This will be used to get round a problem where a PKCS7 | |
7909 | structure which was signed could not be verified because the STACK | |
7910 | order did not reflect the encoded order. | |
7911 | [Steve Henson] | |
7912 | ||
7913 | *) Reimplement the OCSP ASN1 module using the new code. | |
7914 | [Steve Henson] | |
7915 | ||
7916 | *) Update the X509V3 code to permit the use of an ASN1_ITEM structure | |
7917 | for its ASN1 operations. The old style function pointers still exist | |
7918 | for now but they will eventually go away. | |
7919 | [Steve Henson] | |
7920 | ||
7921 | *) Merge in replacement ASN1 code from the ASN1 branch. This almost | |
7922 | completely replaces the old ASN1 functionality with a table driven | |
7923 | encoder and decoder which interprets an ASN1_ITEM structure describing | |
7924 | the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is | |
7925 | largely maintained. Almost all of the old asn1_mac.h macro based ASN1 | |
7926 | has also been converted to the new form. | |
7927 | [Steve Henson] | |
7928 | ||
7929 | *) Change BN_mod_exp_recp so that negative moduli are tolerated | |
7930 | (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set | |
7931 | so that BN_mod_exp_mont and BN_mod_exp_mont_word work | |
7932 | for negative moduli. | |
7933 | [Bodo Moeller] | |
7934 | ||
7935 | *) Fix BN_uadd and BN_usub: Always return non-negative results instead | |
7936 | of not touching the result's sign bit. | |
7937 | [Bodo Moeller] | |
7938 | ||
7939 | *) BN_div bugfix: If the result is 0, the sign (res->neg) must not be | |
7940 | set. | |
7941 | [Bodo Moeller] | |
7942 | ||
7943 | *) Changed the LHASH code to use prototypes for callbacks, and created | |
7944 | macros to declare and implement thin (optionally static) functions | |
7945 | that provide type-safety and avoid function pointer casting for the | |
7946 | type-specific callbacks. | |
7947 | [Geoff Thorpe] | |
7948 | ||
7949 | *) Added Kerberos Cipher Suites to be used with TLS, as written in | |
7950 | RFC 2712. | |
7951 | [Veers Staats <staatsvr@asc.hpc.mil>, | |
7952 | Jeffrey Altman <jaltman@columbia.edu>, via Richard Levitte] | |
7953 | ||
7954 | *) Reformat the FAQ so the different questions and answers can be divided | |
7955 | in sections depending on the subject. | |
7956 | [Richard Levitte] | |
7957 | ||
7958 | *) Have the zlib compression code load ZLIB.DLL dynamically under | |
7959 | Windows. | |
7960 | [Richard Levitte] | |
7961 | ||
7962 | *) New function BN_mod_sqrt for computing square roots modulo a prime | |
7963 | (using the probabilistic Tonelli-Shanks algorithm unless | |
7964 | p == 3 (mod 4) or p == 5 (mod 8), which are cases that can | |
7965 | be handled deterministically). | |
7966 | [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller] | |
7967 | ||
7968 | *) Make BN_mod_inverse faster by explicitly handling small quotients | |
7969 | in the Euclid loop. (Speed gain about 20% for small moduli [256 or | |
7970 | 512 bits], about 30% for larger ones [1024 or 2048 bits].) | |
7971 | [Bodo Moeller] | |
7972 | ||
7973 | *) New function BN_kronecker. | |
7974 | [Bodo Moeller] | |
7975 | ||
7976 | *) Fix BN_gcd so that it works on negative inputs; the result is | |
7977 | positive unless both parameters are zero. | |
7978 | Previously something reasonably close to an infinite loop was | |
7979 | possible because numbers could be growing instead of shrinking | |
7980 | in the implementation of Euclid's algorithm. | |
7981 | [Bodo Moeller] | |
7982 | ||
7983 | *) Fix BN_is_word() and BN_is_one() macros to take into account the | |
7984 | sign of the number in question. | |
7985 | ||
7986 | Fix BN_is_word(a,w) to work correctly for w == 0. | |
7987 | ||
7988 | The old BN_is_word(a,w) macro is now called BN_abs_is_word(a,w) | |
7989 | because its test if the absolute value of 'a' equals 'w'. | |
7990 | Note that BN_abs_is_word does *not* handle w == 0 reliably; | |
7991 | it exists mostly for use in the implementations of BN_is_zero(), | |
7992 | BN_is_one(), and BN_is_word(). | |
7993 | [Bodo Moeller] | |
7994 | ||
7995 | *) New function BN_swap. | |
7996 | [Bodo Moeller] | |
7997 | ||
7998 | *) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that | |
7999 | the exponentiation functions are more likely to produce reasonable | |
8000 | results on negative inputs. | |
8001 | [Bodo Moeller] | |
8002 | ||
8003 | *) Change BN_mod_mul so that the result is always non-negative. | |
8004 | Previously, it could be negative if one of the factors was negative; | |
8005 | I don't think anyone really wanted that behaviour. | |
8006 | [Bodo Moeller] | |
8007 | ||
8008 | *) Move BN_mod_... functions into new file crypto/bn/bn_mod.c | |
8009 | (except for exponentiation, which stays in crypto/bn/bn_exp.c, | |
8010 | and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c) | |
8011 | and add new functions: | |
8012 | ||
8013 | BN_nnmod | |
8014 | BN_mod_sqr | |
8015 | BN_mod_add | |
8016 | BN_mod_add_quick | |
8017 | BN_mod_sub | |
8018 | BN_mod_sub_quick | |
8019 | BN_mod_lshift1 | |
8020 | BN_mod_lshift1_quick | |
8021 | BN_mod_lshift | |
8022 | BN_mod_lshift_quick | |
8023 | ||
8024 | These functions always generate non-negative results. | |
8025 | ||
8026 | BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder r | |
8027 | such that |m| < r < 0, BN_nnmod will output rem + |m| instead). | |
8028 | ||
8029 | BN_mod_XXX_quick(r, a, [b,] m) generates the same result as | |
8030 | BN_mod_XXX(r, a, [b,] m, ctx), but requires that a [and b] | |
8031 | be reduced modulo m. | |
8032 | [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller] | |
8033 | ||
8034 | #if 0 | |
8035 | The following entry accidentally appeared in the CHANGES file | |
8036 | distributed with OpenSSL 0.9.7. The modifications described in | |
8037 | it do *not* apply to OpenSSL 0.9.7. | |
8038 | ||
8039 | *) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there | |
8040 | was actually never needed) and in BN_mul(). The removal in BN_mul() | |
8041 | required a small change in bn_mul_part_recursive() and the addition | |
8042 | of the functions bn_cmp_part_words(), bn_sub_part_words() and | |
8043 | bn_add_part_words(), which do the same thing as bn_cmp_words(), | |
8044 | bn_sub_words() and bn_add_words() except they take arrays with | |
8045 | differing sizes. | |
8046 | [Richard Levitte] | |
8047 | #endif | |
8048 | ||
8049 | *) In 'openssl passwd', verify passwords read from the terminal | |
8050 | unless the '-salt' option is used (which usually means that | |
8051 | verification would just waste user's time since the resulting | |
8052 | hash is going to be compared with some given password hash) | |
8053 | or the new '-noverify' option is used. | |
8054 | ||
8055 | This is an incompatible change, but it does not affect | |
8056 | non-interactive use of 'openssl passwd' (passwords on the command | |
8057 | line, '-stdin' option, '-in ...' option) and thus should not | |
8058 | cause any problems. | |
8059 | [Bodo Moeller] | |
8060 | ||
8061 | *) Remove all references to RSAref, since there's no more need for it. | |
8062 | [Richard Levitte] | |
8063 | ||
8064 | *) Make DSO load along a path given through an environment variable | |
8065 | (SHLIB_PATH) with shl_load(). | |
8066 | [Richard Levitte] | |
8067 | ||
8068 | *) Constify the ENGINE code as a result of BIGNUM constification. | |
8069 | Also constify the RSA code and most things related to it. In a | |
8070 | few places, most notable in the depth of the ASN.1 code, ugly | |
8071 | casts back to non-const were required (to be solved at a later | |
8072 | time) | |
8073 | [Richard Levitte] | |
8074 | ||
8075 | *) Make it so the openssl application has all engines loaded by default. | |
8076 | [Richard Levitte] | |
8077 | ||
8078 | *) Constify the BIGNUM routines a little more. | |
8079 | [Richard Levitte] | |
8080 | ||
8081 | *) Add the following functions: | |
8082 | ||
8083 | ENGINE_load_cswift() | |
8084 | ENGINE_load_chil() | |
8085 | ENGINE_load_atalla() | |
8086 | ENGINE_load_nuron() | |
8087 | ENGINE_load_builtin_engines() | |
8088 | ||
8089 | That way, an application can itself choose if external engines that | |
8090 | are built-in in OpenSSL shall ever be used or not. The benefit is | |
8091 | that applications won't have to be linked with libdl or other dso | |
8092 | libraries unless it's really needed. | |
8093 | ||
8094 | Changed 'openssl engine' to load all engines on demand. | |
8095 | Changed the engine header files to avoid the duplication of some | |
8096 | declarations (they differed!). | |
8097 | [Richard Levitte] | |
8098 | ||
8099 | *) 'openssl engine' can now list capabilities. | |
8100 | [Richard Levitte] | |
8101 | ||
8102 | *) Better error reporting in 'openssl engine'. | |
8103 | [Richard Levitte] | |
8104 | ||
8105 | *) Never call load_dh_param(NULL) in s_server. | |
8106 | [Bodo Moeller] | |
8107 | ||
8108 | *) Add engine application. It can currently list engines by name and | |
8109 | identity, and test if they are actually available. | |
8110 | [Richard Levitte] | |
8111 | ||
8112 | *) Improve RPM specification file by forcing symbolic linking and making | |
8113 | sure the installed documentation is also owned by root.root. | |
8114 | [Damien Miller <djm@mindrot.org>] | |
8115 | ||
8116 | *) Give the OpenSSL applications more possibilities to make use of | |
8117 | keys (public as well as private) handled by engines. | |
8118 | [Richard Levitte] | |
8119 | ||
8120 | *) Add OCSP code that comes from CertCo. | |
8121 | [Richard Levitte] | |
8122 | ||
8123 | *) Add VMS support for the Rijndael code. | |
8124 | [Richard Levitte] | |
8125 | ||
8126 | *) Added untested support for Nuron crypto accelerator. | |
8127 | [Ben Laurie] | |
8128 | ||
8129 | *) Add support for external cryptographic devices. This code was | |
8130 | previously distributed separately as the "engine" branch. | |
8131 | [Geoff Thorpe, Richard Levitte] | |
8132 | ||
8133 | *) Rework the filename-translation in the DSO code. It is now possible to | |
8134 | have far greater control over how a "name" is turned into a filename | |
8135 | depending on the operating environment and any oddities about the | |
8136 | different shared library filenames on each system. | |
8137 | [Geoff Thorpe] | |
8138 | ||
8139 | *) Support threads on FreeBSD-elf in Configure. | |
8140 | [Richard Levitte] | |
8141 | ||
8142 | *) Fix for SHA1 assembly problem with MASM: it produces | |
8143 | warnings about corrupt line number information when assembling | |
8144 | with debugging information. This is caused by the overlapping | |
8145 | of two sections. | |
8146 | [Bernd Matthes <mainbug@celocom.de>, Steve Henson] | |
8147 | ||
8148 | *) NCONF changes. | |
8149 | NCONF_get_number() has no error checking at all. As a replacement, | |
8150 | NCONF_get_number_e() is defined (_e for "error checking") and is | |
8151 | promoted strongly. The old NCONF_get_number is kept around for | |
8152 | binary backward compatibility. | |
8153 | Make it possible for methods to load from something other than a BIO, | |
8154 | by providing a function pointer that is given a name instead of a BIO. | |
8155 | For example, this could be used to load configuration data from an | |
8156 | LDAP server. | |
8157 | [Richard Levitte] | |
8158 | ||
8159 | *) Fix for non blocking accept BIOs. Added new I/O special reason | |
8160 | BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs | |
8161 | with non blocking I/O was not possible because no retry code was | |
8162 | implemented. Also added new SSL code SSL_WANT_ACCEPT to cover | |
8163 | this case. | |
8164 | [Steve Henson] | |
8165 | ||
8166 | *) Added the beginnings of Rijndael support. | |
8167 | [Ben Laurie] | |
8168 | ||
8169 | *) Fix for bug in DirectoryString mask setting. Add support for | |
8170 | X509_NAME_print_ex() in 'req' and X509_print_ex() function | |
8171 | to allow certificate printing to more controllable, additional | |
8172 | 'certopt' option to 'x509' to allow new printing options to be | |
8173 | set. | |
8174 | [Steve Henson] | |
8175 | ||
8176 | *) Clean old EAY MD5 hack from e_os.h. | |
8177 | [Richard Levitte] | |
8178 | ||
8179 | Changes between 0.9.6l and 0.9.6m [17 Mar 2004] | |
8180 | ||
8181 | *) Fix null-pointer assignment in do_change_cipher_spec() revealed | |
8182 | by using the Codenomicon TLS Test Tool (CVE-2004-0079) | |
8183 | [Joe Orton, Steve Henson] | |
8184 | ||
8185 | Changes between 0.9.6k and 0.9.6l [04 Nov 2003] | |
8186 | ||
8187 | *) Fix additional bug revealed by the NISCC test suite: | |
8188 | ||
8189 | Stop bug triggering large recursion when presented with | |
8190 | certain ASN.1 tags (CVE-2003-0851) | |
8191 | [Steve Henson] | |
8192 | ||
8193 | Changes between 0.9.6j and 0.9.6k [30 Sep 2003] | |
8194 | ||
8195 | *) Fix various bugs revealed by running the NISCC test suite: | |
8196 | ||
8197 | Stop out of bounds reads in the ASN1 code when presented with | |
8198 | invalid tags (CVE-2003-0543 and CVE-2003-0544). | |
8199 | ||
8200 | If verify callback ignores invalid public key errors don't try to check | |
8201 | certificate signature with the NULL public key. | |
8202 | ||
8203 | [Steve Henson] | |
8204 | ||
8205 | *) In ssl3_accept() (ssl/s3_srvr.c) only accept a client certificate | |
8206 | if the server requested one: as stated in TLS 1.0 and SSL 3.0 | |
8207 | specifications. | |
8208 | [Steve Henson] | |
8209 | ||
8210 | *) In ssl3_get_client_hello() (ssl/s3_srvr.c), tolerate additional | |
8211 | extra data after the compression methods not only for TLS 1.0 | |
8212 | but also for SSL 3.0 (as required by the specification). | |
8213 | [Bodo Moeller; problem pointed out by Matthias Loepfe] | |
8214 | ||
8215 | *) Change X509_certificate_type() to mark the key as exported/exportable | |
8216 | when it's 512 *bits* long, not 512 bytes. | |
8217 | [Richard Levitte] | |
8218 | ||
8219 | Changes between 0.9.6i and 0.9.6j [10 Apr 2003] | |
8220 | ||
8221 | *) Countermeasure against the Klima-Pokorny-Rosa extension of | |
8222 | Bleichbacher's attack on PKCS #1 v1.5 padding: treat | |
8223 | a protocol version number mismatch like a decryption error | |
8224 | in ssl3_get_client_key_exchange (ssl/s3_srvr.c). | |
8225 | [Bodo Moeller] | |
8226 | ||
8227 | *) Turn on RSA blinding by default in the default implementation | |
8228 | to avoid a timing attack. Applications that don't want it can call | |
8229 | RSA_blinding_off() or use the new flag RSA_FLAG_NO_BLINDING. | |
8230 | They would be ill-advised to do so in most cases. | |
8231 | [Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller] | |
8232 | ||
8233 | *) Change RSA blinding code so that it works when the PRNG is not | |
8234 | seeded (in this case, the secret RSA exponent is abused as | |
8235 | an unpredictable seed -- if it is not unpredictable, there | |
8236 | is no point in blinding anyway). Make RSA blinding thread-safe | |
8237 | by remembering the creator's thread ID in rsa->blinding and | |
8238 | having all other threads use local one-time blinding factors | |
8239 | (this requires more computation than sharing rsa->blinding, but | |
8240 | avoids excessive locking; and if an RSA object is not shared | |
8241 | between threads, blinding will still be very fast). | |
8242 | [Bodo Moeller] | |
8243 | ||
8244 | Changes between 0.9.6h and 0.9.6i [19 Feb 2003] | |
8245 | ||
8246 | *) In ssl3_get_record (ssl/s3_pkt.c), minimize information leaked | |
8247 | via timing by performing a MAC computation even if incorrect | |
8248 | block cipher padding has been found. This is a countermeasure | |
8249 | against active attacks where the attacker has to distinguish | |
8250 | between bad padding and a MAC verification error. (CVE-2003-0078) | |
8251 | ||
8252 | [Bodo Moeller; problem pointed out by Brice Canvel (EPFL), | |
8253 | Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and | |
8254 | Martin Vuagnoux (EPFL, Ilion)] | |
8255 | ||
8256 | Changes between 0.9.6g and 0.9.6h [5 Dec 2002] | |
8257 | ||
8258 | *) New function OPENSSL_cleanse(), which is used to cleanse a section of | |
8259 | memory from it's contents. This is done with a counter that will | |
8260 | place alternating values in each byte. This can be used to solve | |
8261 | two issues: 1) the removal of calls to memset() by highly optimizing | |
8262 | compilers, and 2) cleansing with other values than 0, since those can | |
8263 | be read through on certain media, for example a swap space on disk. | |
8264 | [Geoff Thorpe] | |
8265 | ||
8266 | *) Bugfix: client side session caching did not work with external caching, | |
8267 | because the session->cipher setting was not restored when reloading | |
8268 | from the external cache. This problem was masked, when | |
8269 | SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG (part of SSL_OP_ALL) was set. | |
8270 | (Found by Steve Haslam <steve@araqnid.ddts.net>.) | |
8271 | [Lutz Jaenicke] | |
8272 | ||
8273 | *) Fix client_certificate (ssl/s2_clnt.c): The permissible total | |
8274 | length of the REQUEST-CERTIFICATE message is 18 .. 34, not 17 .. 33. | |
8275 | [Zeev Lieber <zeev-l@yahoo.com>] | |
8276 | ||
8277 | *) Undo an undocumented change introduced in 0.9.6e which caused | |
8278 | repeated calls to OpenSSL_add_all_ciphers() and | |
8279 | OpenSSL_add_all_digests() to be ignored, even after calling | |
8280 | EVP_cleanup(). | |
8281 | [Richard Levitte] | |
8282 | ||
8283 | *) Change the default configuration reader to deal with last line not | |
8284 | being properly terminated. | |
8285 | [Richard Levitte] | |
8286 | ||
8287 | *) Change X509_NAME_cmp() so it applies the special rules on handling | |
8288 | DN values that are of type PrintableString, as well as RDNs of type | |
8289 | emailAddress where the value has the type ia5String. | |
8290 | [stefank@valicert.com via Richard Levitte] | |
8291 | ||
8292 | *) Add a SSL_SESS_CACHE_NO_INTERNAL_STORE flag to take over half | |
8293 | the job SSL_SESS_CACHE_NO_INTERNAL_LOOKUP was inconsistently | |
8294 | doing, define a new flag (SSL_SESS_CACHE_NO_INTERNAL) to be | |
8295 | the bitwise-OR of the two for use by the majority of applications | |
8296 | wanting this behaviour, and update the docs. The documented | |
8297 | behaviour and actual behaviour were inconsistent and had been | |
8298 | changing anyway, so this is more a bug-fix than a behavioural | |
8299 | change. | |
8300 | [Geoff Thorpe, diagnosed by Nadav Har'El] | |
8301 | ||
8302 | *) Don't impose a 16-byte length minimum on session IDs in ssl/s3_clnt.c | |
8303 | (the SSL 3.0 and TLS 1.0 specifications allow any length up to 32 bytes). | |
8304 | [Bodo Moeller] | |
8305 | ||
8306 | *) Fix initialization code race conditions in | |
8307 | SSLv23_method(), SSLv23_client_method(), SSLv23_server_method(), | |
8308 | SSLv2_method(), SSLv2_client_method(), SSLv2_server_method(), | |
8309 | SSLv3_method(), SSLv3_client_method(), SSLv3_server_method(), | |
8310 | TLSv1_method(), TLSv1_client_method(), TLSv1_server_method(), | |
8311 | ssl2_get_cipher_by_char(), | |
8312 | ssl3_get_cipher_by_char(). | |
8313 | [Patrick McCormick <patrick@tellme.com>, Bodo Moeller] | |
8314 | ||
8315 | *) Reorder cleanup sequence in SSL_CTX_free(): only remove the ex_data after | |
8316 | the cached sessions are flushed, as the remove_cb() might use ex_data | |
8317 | contents. Bug found by Sam Varshavchik <mrsam@courier-mta.com> | |
8318 | (see [openssl.org #212]). | |
8319 | [Geoff Thorpe, Lutz Jaenicke] | |
8320 | ||
8321 | *) Fix typo in OBJ_txt2obj which incorrectly passed the content | |
8322 | length, instead of the encoding length to d2i_ASN1_OBJECT. | |
8323 | [Steve Henson] | |
8324 | ||
8325 | Changes between 0.9.6f and 0.9.6g [9 Aug 2002] | |
8326 | ||
8327 | *) [In 0.9.6g-engine release:] | |
8328 | Fix crypto/engine/vendor_defns/cswift.h for WIN32 (use '_stdcall'). | |
8329 | [Lynn Gazis <lgazis@rainbow.com>] | |
8330 | ||
8331 | Changes between 0.9.6e and 0.9.6f [8 Aug 2002] | |
8332 | ||
8333 | *) Fix ASN1 checks. Check for overflow by comparing with LONG_MAX | |
8334 | and get fix the header length calculation. | |
8335 | [Florian Weimer <Weimer@CERT.Uni-Stuttgart.DE>, | |
8336 | Alon Kantor <alonk@checkpoint.com> (and others), | |
8337 | Steve Henson] | |
8338 | ||
8339 | *) Use proper error handling instead of 'assertions' in buffer | |
8340 | overflow checks added in 0.9.6e. This prevents DoS (the | |
8341 | assertions could call abort()). | |
8342 | [Arne Ansper <arne@ats.cyber.ee>, Bodo Moeller] | |
8343 | ||
8344 | Changes between 0.9.6d and 0.9.6e [30 Jul 2002] | |
8345 | ||
8346 | *) Add various sanity checks to asn1_get_length() to reject | |
8347 | the ASN1 length bytes if they exceed sizeof(long), will appear | |
8348 | negative or the content length exceeds the length of the | |
8349 | supplied buffer. | |
8350 | [Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>] | |
8351 | ||
8352 | *) Fix cipher selection routines: ciphers without encryption had no flags | |
8353 | for the cipher strength set and where therefore not handled correctly | |
8354 | by the selection routines (PR #130). | |
8355 | [Lutz Jaenicke] | |
8356 | ||
8357 | *) Fix EVP_dsa_sha macro. | |
8358 | [Nils Larsch] | |
8359 | ||
8360 | *) New option | |
8361 | SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS | |
8362 | for disabling the SSL 3.0/TLS 1.0 CBC vulnerability countermeasure | |
8363 | that was added in OpenSSL 0.9.6d. | |
8364 | ||
8365 | As the countermeasure turned out to be incompatible with some | |
8366 | broken SSL implementations, the new option is part of SSL_OP_ALL. | |
8367 | SSL_OP_ALL is usually employed when compatibility with weird SSL | |
8368 | implementations is desired (e.g. '-bugs' option to 's_client' and | |
8369 | 's_server'), so the new option is automatically set in many | |
8370 | applications. | |
8371 | [Bodo Moeller] | |
8372 | ||
8373 | *) Changes in security patch: | |
8374 | ||
8375 | Changes marked "(CHATS)" were sponsored by the Defense Advanced | |
8376 | Research Projects Agency (DARPA) and Air Force Research Laboratory, | |
8377 | Air Force Materiel Command, USAF, under agreement number | |
8378 | F30602-01-2-0537. | |
8379 | ||
8380 | *) Add various sanity checks to asn1_get_length() to reject | |
8381 | the ASN1 length bytes if they exceed sizeof(long), will appear | |
8382 | negative or the content length exceeds the length of the | |
8383 | supplied buffer. (CVE-2002-0659) | |
8384 | [Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>] | |
8385 | ||
8386 | *) Assertions for various potential buffer overflows, not known to | |
8387 | happen in practice. | |
8388 | [Ben Laurie (CHATS)] | |
8389 | ||
8390 | *) Various temporary buffers to hold ASCII versions of integers were | |
8391 | too small for 64 bit platforms. (CVE-2002-0655) | |
8392 | [Matthew Byng-Maddick <mbm@aldigital.co.uk> and Ben Laurie (CHATS)> | |
8393 | ||
8394 | *) Remote buffer overflow in SSL3 protocol - an attacker could | |
8395 | supply an oversized session ID to a client. (CVE-2002-0656) | |
8396 | [Ben Laurie (CHATS)] | |
8397 | ||
8398 | *) Remote buffer overflow in SSL2 protocol - an attacker could | |
8399 | supply an oversized client master key. (CVE-2002-0656) | |
8400 | [Ben Laurie (CHATS)] | |
8401 | ||
8402 | Changes between 0.9.6c and 0.9.6d [9 May 2002] | |
8403 | ||
8404 | *) Fix crypto/asn1/a_sign.c so that 'parameters' is omitted (not | |
8405 | encoded as NULL) with id-dsa-with-sha1. | |
8406 | [Nils Larsch <nla@trustcenter.de>; problem pointed out by Bodo Moeller] | |
8407 | ||
8408 | *) Check various X509_...() return values in apps/req.c. | |
8409 | [Nils Larsch <nla@trustcenter.de>] | |
8410 | ||
8411 | *) Fix BASE64 decode (EVP_DecodeUpdate) for data with CR/LF ended lines: | |
8412 | an end-of-file condition would erroneously be flagged, when the CRLF | |
8413 | was just at the end of a processed block. The bug was discovered when | |
8414 | processing data through a buffering memory BIO handing the data to a | |
8415 | BASE64-decoding BIO. Bug fund and patch submitted by Pavel Tsekov | |
8416 | <ptsekov@syntrex.com> and Nedelcho Stanev. | |
8417 | [Lutz Jaenicke] | |
8418 | ||
8419 | *) Implement a countermeasure against a vulnerability recently found | |
8420 | in CBC ciphersuites in SSL 3.0/TLS 1.0: Send an empty fragment | |
8421 | before application data chunks to avoid the use of known IVs | |
8422 | with data potentially chosen by the attacker. | |
8423 | [Bodo Moeller] | |
8424 | ||
8425 | *) Fix length checks in ssl3_get_client_hello(). | |
8426 | [Bodo Moeller] | |
8427 | ||
8428 | *) TLS/SSL library bugfix: use s->s3->in_read_app_data differently | |
8429 | to prevent ssl3_read_internal() from incorrectly assuming that | |
8430 | ssl3_read_bytes() found application data while handshake | |
8431 | processing was enabled when in fact s->s3->in_read_app_data was | |
8432 | merely automatically cleared during the initial handshake. | |
8433 | [Bodo Moeller; problem pointed out by Arne Ansper <arne@ats.cyber.ee>] | |
8434 | ||
8435 | *) Fix object definitions for Private and Enterprise: they were not | |
8436 | recognized in their shortname (=lowercase) representation. Extend | |
8437 | obj_dat.pl to issue an error when using undefined keywords instead | |
8438 | of silently ignoring the problem (Svenning Sorensen | |
8439 | <sss@sss.dnsalias.net>). | |
8440 | [Lutz Jaenicke] | |
8441 | ||
8442 | *) Fix DH_generate_parameters() so that it works for 'non-standard' | |
8443 | generators, i.e. generators other than 2 and 5. (Previously, the | |
8444 | code did not properly initialise the 'add' and 'rem' values to | |
8445 | BN_generate_prime().) | |
8446 | ||
8447 | In the new general case, we do not insist that 'generator' is | |
8448 | actually a primitive root: This requirement is rather pointless; | |
8449 | a generator of the order-q subgroup is just as good, if not | |
8450 | better. | |
8451 | [Bodo Moeller] | |
8452 | ||
8453 | *) Map new X509 verification errors to alerts. Discovered and submitted by | |
8454 | Tom Wu <tom@arcot.com>. | |
8455 | [Lutz Jaenicke] | |
8456 | ||
8457 | *) Fix ssl3_pending() (ssl/s3_lib.c) to prevent SSL_pending() from | |
8458 | returning non-zero before the data has been completely received | |
8459 | when using non-blocking I/O. | |
8460 | [Bodo Moeller; problem pointed out by John Hughes] | |
8461 | ||
8462 | *) Some of the ciphers missed the strength entry (SSL_LOW etc). | |
8463 | [Ben Laurie, Lutz Jaenicke] | |
8464 | ||
8465 | *) Fix bug in SSL_clear(): bad sessions were not removed (found by | |
8466 | Yoram Zahavi <YoramZ@gilian.com>). | |
8467 | [Lutz Jaenicke] | |
8468 | ||
8469 | *) Add information about CygWin 1.3 and on, and preserve proper | |
8470 | configuration for the versions before that. | |
8471 | [Corinna Vinschen <vinschen@redhat.com> and Richard Levitte] | |
8472 | ||
8473 | *) Make removal from session cache (SSL_CTX_remove_session()) more robust: | |
8474 | check whether we deal with a copy of a session and do not delete from | |
8475 | the cache in this case. Problem reported by "Izhar Shoshani Levi" | |
8476 | <izhar@checkpoint.com>. | |
8477 | [Lutz Jaenicke] | |
8478 | ||
8479 | *) Do not store session data into the internal session cache, if it | |
8480 | is never intended to be looked up (SSL_SESS_CACHE_NO_INTERNAL_LOOKUP | |
8481 | flag is set). Proposed by Aslam <aslam@funk.com>. | |
8482 | [Lutz Jaenicke] | |
8483 | ||
8484 | *) Have ASN1_BIT_STRING_set_bit() really clear a bit when the requested | |
8485 | value is 0. | |
8486 | [Richard Levitte] | |
8487 | ||
8488 | *) [In 0.9.6d-engine release:] | |
8489 | Fix a crashbug and a logic bug in hwcrhk_load_pubkey(). | |
8490 | [Toomas Kiisk <vix@cyber.ee> via Richard Levitte] | |
8491 | ||
8492 | *) Add the configuration target linux-s390x. | |
8493 | [Neale Ferguson <Neale.Ferguson@SoftwareAG-USA.com> via Richard Levitte] | |
8494 | ||
8495 | *) The earlier bugfix for the SSL3_ST_SW_HELLO_REQ_C case of | |
8496 | ssl3_accept (ssl/s3_srvr.c) incorrectly used a local flag | |
8497 | variable as an indication that a ClientHello message has been | |
8498 | received. As the flag value will be lost between multiple | |
8499 | invocations of ssl3_accept when using non-blocking I/O, the | |
8500 | function may not be aware that a handshake has actually taken | |
8501 | place, thus preventing a new session from being added to the | |
8502 | session cache. | |
8503 | ||
8504 | To avoid this problem, we now set s->new_session to 2 instead of | |
8505 | using a local variable. | |
8506 | [Lutz Jaenicke, Bodo Moeller] | |
8507 | ||
8508 | *) Bugfix: Return -1 from ssl3_get_server_done (ssl3/s3_clnt.c) | |
8509 | if the SSL_R_LENGTH_MISMATCH error is detected. | |
8510 | [Geoff Thorpe, Bodo Moeller] | |
8511 | ||
8512 | *) New 'shared_ldflag' column in Configure platform table. | |
8513 | [Richard Levitte] | |
8514 | ||
8515 | *) Fix EVP_CIPHER_mode macro. | |
8516 | ["Dan S. Camper" <dan@bti.net>] | |
8517 | ||
8518 | *) Fix ssl3_read_bytes (ssl/s3_pkt.c): To ignore messages of unknown | |
8519 | type, we must throw them away by setting rr->length to 0. | |
8520 | [D P Chang <dpc@qualys.com>] | |
8521 | ||
8522 | Changes between 0.9.6b and 0.9.6c [21 dec 2001] | |
8523 | ||
8524 | *) Fix BN_rand_range bug pointed out by Dominikus Scherkl | |
8525 | <Dominikus.Scherkl@biodata.com>. (The previous implementation | |
8526 | worked incorrectly for those cases where range = 10..._2 and | |
8527 | 3*range is two bits longer than range.) | |
8528 | [Bodo Moeller] | |
8529 | ||
8530 | *) Only add signing time to PKCS7 structures if it is not already | |
8531 | present. | |
8532 | [Steve Henson] | |
8533 | ||
8534 | *) Fix crypto/objects/objects.h: "ld-ce" should be "id-ce", | |
8535 | OBJ_ld_ce should be OBJ_id_ce. | |
8536 | Also some ip-pda OIDs in crypto/objects/objects.txt were | |
8537 | incorrect (cf. RFC 3039). | |
8538 | [Matt Cooper, Frederic Giudicelli, Bodo Moeller] | |
8539 | ||
8540 | *) Release CRYPTO_LOCK_DYNLOCK when CRYPTO_destroy_dynlockid() | |
8541 | returns early because it has nothing to do. | |
8542 | [Andy Schneider <andy.schneider@bjss.co.uk>] | |
8543 | ||
8544 | *) [In 0.9.6c-engine release:] | |
8545 | Fix mutex callback return values in crypto/engine/hw_ncipher.c. | |
8546 | [Andy Schneider <andy.schneider@bjss.co.uk>] | |
8547 | ||
8548 | *) [In 0.9.6c-engine release:] | |
8549 | Add support for Cryptographic Appliance's keyserver technology. | |
8550 | (Use engine 'keyclient') | |
8551 | [Cryptographic Appliances and Geoff Thorpe] | |
8552 | ||
8553 | *) Add a configuration entry for OS/390 Unix. The C compiler 'c89' | |
8554 | is called via tools/c89.sh because arguments have to be | |
8555 | rearranged (all '-L' options must appear before the first object | |
8556 | modules). | |
8557 | [Richard Shapiro <rshapiro@abinitio.com>] | |
8558 | ||
8559 | *) [In 0.9.6c-engine release:] | |
8560 | Add support for Broadcom crypto accelerator cards, backported | |
8561 | from 0.9.7. | |
8562 | [Broadcom, Nalin Dahyabhai <nalin@redhat.com>, Mark Cox] | |
8563 | ||
8564 | *) [In 0.9.6c-engine release:] | |
8565 | Add support for SureWare crypto accelerator cards from | |
8566 | Baltimore Technologies. (Use engine 'sureware') | |
8567 | [Baltimore Technologies and Mark Cox] | |
8568 | ||
8569 | *) [In 0.9.6c-engine release:] | |
8570 | Add support for crypto accelerator cards from Accelerated | |
8571 | Encryption Processing, www.aep.ie. (Use engine 'aep') | |
8572 | [AEP Inc. and Mark Cox] | |
8573 | ||
8574 | *) Add a configuration entry for gcc on UnixWare. | |
8575 | [Gary Benson <gbenson@redhat.com>] | |
8576 | ||
8577 | *) Change ssl/s2_clnt.c and ssl/s2_srvr.c so that received handshake | |
8578 | messages are stored in a single piece (fixed-length part and | |
8579 | variable-length part combined) and fix various bugs found on the way. | |
8580 | [Bodo Moeller] | |
8581 | ||
8582 | *) Disable caching in BIO_gethostbyname(), directly use gethostbyname() | |
8583 | instead. BIO_gethostbyname() does not know what timeouts are | |
8584 | appropriate, so entries would stay in cache even when they have | |
8585 | become invalid. | |
8586 | [Bodo Moeller; problem pointed out by Rich Salz <rsalz@zolera.com> | |
8587 | ||
8588 | *) Change ssl23_get_client_hello (ssl/s23_srvr.c) behaviour when | |
8589 | faced with a pathologically small ClientHello fragment that does | |
8590 | not contain client_version: Instead of aborting with an error, | |
8591 | simply choose the highest available protocol version (i.e., | |
8592 | TLS 1.0 unless it is disabled). In practice, ClientHello | |
8593 | messages are never sent like this, but this change gives us | |
8594 | strictly correct behaviour at least for TLS. | |
8595 | [Bodo Moeller] | |
8596 | ||
8597 | *) Fix SSL handshake functions and SSL_clear() such that SSL_clear() | |
8598 | never resets s->method to s->ctx->method when called from within | |
8599 | one of the SSL handshake functions. | |
8600 | [Bodo Moeller; problem pointed out by Niko Baric] | |
8601 | ||
8602 | *) In ssl3_get_client_hello (ssl/s3_srvr.c), generate a fatal alert | |
8603 | (sent using the client's version number) if client_version is | |
8604 | smaller than the protocol version in use. Also change | |
8605 | ssl23_get_client_hello (ssl/s23_srvr.c) to select TLS 1.0 if | |
8606 | the client demanded SSL 3.0 but only TLS 1.0 is enabled; then | |
8607 | the client will at least see that alert. | |
8608 | [Bodo Moeller] | |
8609 | ||
8610 | *) Fix ssl3_get_message (ssl/s3_both.c) to handle message fragmentation | |
8611 | correctly. | |
8612 | [Bodo Moeller] | |
8613 | ||
8614 | *) Avoid infinite loop in ssl3_get_message (ssl/s3_both.c) if a | |
8615 | client receives HelloRequest while in a handshake. | |
8616 | [Bodo Moeller; bug noticed by Andy Schneider <andy.schneider@bjss.co.uk>] | |
8617 | ||
8618 | *) Bugfix in ssl3_accept (ssl/s3_srvr.c): Case SSL3_ST_SW_HELLO_REQ_C | |
8619 | should end in 'break', not 'goto end' which circumvents various | |
8620 | cleanups done in state SSL_ST_OK. But session related stuff | |
8621 | must be disabled for SSL_ST_OK in the case that we just sent a | |
8622 | HelloRequest. | |
8623 | ||
8624 | Also avoid some overhead by not calling ssl_init_wbio_buffer() | |
8625 | before just sending a HelloRequest. | |
8626 | [Bodo Moeller, Eric Rescorla <ekr@rtfm.com>] | |
8627 | ||
8628 | *) Fix ssl/s3_enc.c, ssl/t1_enc.c and ssl/s3_pkt.c so that we don't | |
8629 | reveal whether illegal block cipher padding was found or a MAC | |
8630 | verification error occurred. (Neither SSLerr() codes nor alerts | |
8631 | are directly visible to potential attackers, but the information | |
8632 | may leak via logfiles.) | |
8633 | ||
8634 | Similar changes are not required for the SSL 2.0 implementation | |
8635 | because the number of padding bytes is sent in clear for SSL 2.0, | |
8636 | and the extra bytes are just ignored. However ssl/s2_pkt.c | |
8637 | failed to verify that the purported number of padding bytes is in | |
8638 | the legal range. | |
8639 | [Bodo Moeller] | |
8640 | ||
8641 | *) Add OpenUNIX-8 support including shared libraries | |
8642 | (Boyd Lynn Gerber <gerberb@zenez.com>). | |
8643 | [Lutz Jaenicke] | |
8644 | ||
8645 | *) Improve RSA_padding_check_PKCS1_OAEP() check again to avoid | |
8646 | 'wristwatch attack' using huge encoding parameters (cf. | |
8647 | James H. Manger's CRYPTO 2001 paper). Note that the | |
8648 | RSA_PKCS1_OAEP_PADDING case of RSA_private_decrypt() does not use | |
8649 | encoding parameters and hence was not vulnerable. | |
8650 | [Bodo Moeller] | |
8651 | ||
8652 | *) BN_sqr() bug fix. | |
8653 | [Ulf Möller, reported by Jim Ellis <jim.ellis@cavium.com>] | |
8654 | ||
8655 | *) Rabin-Miller test analyses assume uniformly distributed witnesses, | |
8656 | so use BN_pseudo_rand_range() instead of using BN_pseudo_rand() | |
8657 | followed by modular reduction. | |
8658 | [Bodo Moeller; pointed out by Adam Young <AYoung1@NCSUS.JNJ.COM>] | |
8659 | ||
8660 | *) Add BN_pseudo_rand_range() with obvious functionality: BN_rand_range() | |
8661 | equivalent based on BN_pseudo_rand() instead of BN_rand(). | |
8662 | [Bodo Moeller] | |
8663 | ||
8664 | *) s3_srvr.c: allow sending of large client certificate lists (> 16 kB). | |
8665 | This function was broken, as the check for a new client hello message | |
8666 | to handle SGC did not allow these large messages. | |
8667 | (Tracked down by "Douglas E. Engert" <deengert@anl.gov>.) | |
8668 | [Lutz Jaenicke] | |
8669 | ||
8670 | *) Add alert descriptions for TLSv1 to SSL_alert_desc_string[_long](). | |
8671 | [Lutz Jaenicke] | |
8672 | ||
8673 | *) Fix buggy behaviour of BIO_get_num_renegotiates() and BIO_ctrl() | |
8674 | for BIO_C_GET_WRITE_BUF_SIZE ("Stephen Hinton" <shinton@netopia.com>). | |
8675 | [Lutz Jaenicke] | |
8676 | ||
8677 | *) Rework the configuration and shared library support for Tru64 Unix. | |
8678 | The configuration part makes use of modern compiler features and | |
8679 | still retains old compiler behavior for those that run older versions | |
8680 | of the OS. The shared library support part includes a variant that | |
8681 | uses the RPATH feature, and is available through the special | |
8682 | configuration target "alpha-cc-rpath", which will never be selected | |
8683 | automatically. | |
8684 | [Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu> via Richard Levitte] | |
8685 | ||
8686 | *) In ssl3_get_key_exchange (ssl/s3_clnt.c), call ssl3_get_message() | |
8687 | with the same message size as in ssl3_get_certificate_request(). | |
8688 | Otherwise, if no ServerKeyExchange message occurs, CertificateRequest | |
8689 | messages might inadvertently be reject as too long. | |
8690 | [Petr Lampa <lampa@fee.vutbr.cz>] | |
8691 | ||
8692 | *) Enhanced support for IA-64 Unix platforms (well, Linux and HP-UX). | |
8693 | [Andy Polyakov] | |
8694 | ||
8695 | *) Modified SSL library such that the verify_callback that has been set | |
8696 | specificly for an SSL object with SSL_set_verify() is actually being | |
8697 | used. Before the change, a verify_callback set with this function was | |
8698 | ignored and the verify_callback() set in the SSL_CTX at the time of | |
8699 | the call was used. New function X509_STORE_CTX_set_verify_cb() introduced | |
8700 | to allow the necessary settings. | |
8701 | [Lutz Jaenicke] | |
8702 | ||
8703 | *) Initialize static variable in crypto/dsa/dsa_lib.c and crypto/dh/dh_lib.c | |
8704 | explicitly to NULL, as at least on Solaris 8 this seems not always to be | |
8705 | done automatically (in contradiction to the requirements of the C | |
8706 | standard). This made problems when used from OpenSSH. | |
8707 | [Lutz Jaenicke] | |
8708 | ||
8709 | *) In OpenSSL 0.9.6a and 0.9.6b, crypto/dh/dh_key.c ignored | |
8710 | dh->length and always used | |
8711 | ||
8712 | BN_rand_range(priv_key, dh->p). | |
8713 | ||
8714 | BN_rand_range() is not necessary for Diffie-Hellman, and this | |
8715 | specific range makes Diffie-Hellman unnecessarily inefficient if | |
8716 | dh->length (recommended exponent length) is much smaller than the | |
8717 | length of dh->p. We could use BN_rand_range() if the order of | |
8718 | the subgroup was stored in the DH structure, but we only have | |
8719 | dh->length. | |
8720 | ||
8721 | So switch back to | |
8722 | ||
8723 | BN_rand(priv_key, l, ...) | |
8724 | ||
8725 | where 'l' is dh->length if this is defined, or BN_num_bits(dh->p)-1 | |
8726 | otherwise. | |
8727 | [Bodo Moeller] | |
8728 | ||
8729 | *) In | |
8730 | ||
8731 | RSA_eay_public_encrypt | |
8732 | RSA_eay_private_decrypt | |
8733 | RSA_eay_private_encrypt (signing) | |
8734 | RSA_eay_public_decrypt (signature verification) | |
8735 | ||
8736 | (default implementations for RSA_public_encrypt, | |
8737 | RSA_private_decrypt, RSA_private_encrypt, RSA_public_decrypt), | |
8738 | always reject numbers >= n. | |
8739 | [Bodo Moeller] | |
8740 | ||
8741 | *) In crypto/rand/md_rand.c, use a new short-time lock CRYPTO_LOCK_RAND2 | |
8742 | to synchronize access to 'locking_thread'. This is necessary on | |
8743 | systems where access to 'locking_thread' (an 'unsigned long' | |
8744 | variable) is not atomic. | |
8745 | [Bodo Moeller] | |
8746 | ||
8747 | *) In crypto/rand/md_rand.c, set 'locking_thread' to current thread's ID | |
8748 | *before* setting the 'crypto_lock_rand' flag. The previous code had | |
8749 | a race condition if 0 is a valid thread ID. | |
8750 | [Travis Vitek <vitek@roguewave.com>] | |
8751 | ||
8752 | *) Add support for shared libraries under Irix. | |
8753 | [Albert Chin-A-Young <china@thewrittenword.com>] | |
8754 | ||
8755 | *) Add configuration option to build on Linux on both big-endian and | |
8756 | little-endian MIPS. | |
8757 | [Ralf Baechle <ralf@uni-koblenz.de>] | |
8758 | ||
8759 | *) Add the possibility to create shared libraries on HP-UX. | |
8760 | [Richard Levitte] | |
8761 | ||
8762 | Changes between 0.9.6a and 0.9.6b [9 Jul 2001] | |
8763 | ||
8764 | *) Change ssleay_rand_bytes (crypto/rand/md_rand.c) | |
8765 | to avoid a SSLeay/OpenSSL PRNG weakness pointed out by | |
8766 | Markku-Juhani O. Saarinen <markku-juhani.saarinen@nokia.com>: | |
8767 | PRNG state recovery was possible based on the output of | |
8768 | one PRNG request appropriately sized to gain knowledge on | |
8769 | 'md' followed by enough consecutive 1-byte PRNG requests | |
8770 | to traverse all of 'state'. | |
8771 | ||
8772 | 1. When updating 'md_local' (the current thread's copy of 'md') | |
8773 | during PRNG output generation, hash all of the previous | |
8774 | 'md_local' value, not just the half used for PRNG output. | |
8775 | ||
8776 | 2. Make the number of bytes from 'state' included into the hash | |
8777 | independent from the number of PRNG bytes requested. | |
8778 | ||
8779 | The first measure alone would be sufficient to avoid | |
8780 | Markku-Juhani's attack. (Actually it had never occurred | |
8781 | to me that the half of 'md_local' used for chaining was the | |
8782 | half from which PRNG output bytes were taken -- I had always | |
8783 | assumed that the secret half would be used.) The second | |
8784 | measure makes sure that additional data from 'state' is never | |
8785 | mixed into 'md_local' in small portions; this heuristically | |
8786 | further strengthens the PRNG. | |
8787 | [Bodo Moeller] | |
8788 | ||
8789 | *) Fix crypto/bn/asm/mips3.s. | |
8790 | [Andy Polyakov] | |
8791 | ||
8792 | *) When only the key is given to "enc", the IV is undefined. Print out | |
8793 | an error message in this case. | |
8794 | [Lutz Jaenicke] | |
8795 | ||
8796 | *) Handle special case when X509_NAME is empty in X509 printing routines. | |
8797 | [Steve Henson] | |
8798 | ||
8799 | *) In dsa_do_verify (crypto/dsa/dsa_ossl.c), verify that r and s are | |
8800 | positive and less than q. | |
8801 | [Bodo Moeller] | |
8802 | ||
8803 | *) Don't change *pointer in CRYPTO_add_lock() is add_lock_callback is | |
8804 | used: it isn't thread safe and the add_lock_callback should handle | |
8805 | that itself. | |
8806 | [Paul Rose <Paul.Rose@bridge.com>] | |
8807 | ||
8808 | *) Verify that incoming data obeys the block size in | |
8809 | ssl3_enc (ssl/s3_enc.c) and tls1_enc (ssl/t1_enc.c). | |
8810 | [Bodo Moeller] | |
8811 | ||
8812 | *) Fix OAEP check. | |
8813 | [Ulf Möller, Bodo Möller] | |
8814 | ||
8815 | *) The countermeasure against Bleichbacher's attack on PKCS #1 v1.5 | |
8816 | RSA encryption was accidentally removed in s3_srvr.c in OpenSSL 0.9.5 | |
8817 | when fixing the server behaviour for backwards-compatible 'client | |
8818 | hello' messages. (Note that the attack is impractical against | |
8819 | SSL 3.0 and TLS 1.0 anyway because length and version checking | |
8820 | means that the probability of guessing a valid ciphertext is | |
8821 | around 2^-40; see section 5 in Bleichenbacher's CRYPTO '98 | |
8822 | paper.) | |
8823 | ||
8824 | Before 0.9.5, the countermeasure (hide the error by generating a | |
8825 | random 'decryption result') did not work properly because | |
8826 | ERR_clear_error() was missing, meaning that SSL_get_error() would | |
8827 | detect the supposedly ignored error. | |
8828 | ||
8829 | Both problems are now fixed. | |
8830 | [Bodo Moeller] | |
8831 | ||
8832 | *) In crypto/bio/bf_buff.c, increase DEFAULT_BUFFER_SIZE to 4096 | |
8833 | (previously it was 1024). | |
8834 | [Bodo Moeller] | |
8835 | ||
8836 | *) Fix for compatibility mode trust settings: ignore trust settings | |
8837 | unless some valid trust or reject settings are present. | |
8838 | [Steve Henson] | |
8839 | ||
8840 | *) Fix for blowfish EVP: its a variable length cipher. | |
8841 | [Steve Henson] | |
8842 | ||
8843 | *) Fix various bugs related to DSA S/MIME verification. Handle missing | |
8844 | parameters in DSA public key structures and return an error in the | |
8845 | DSA routines if parameters are absent. | |
8846 | [Steve Henson] | |
8847 | ||
8848 | *) In versions up to 0.9.6, RAND_file_name() resorted to file ".rnd" | |
8849 | in the current directory if neither $RANDFILE nor $HOME was set. | |
8850 | RAND_file_name() in 0.9.6a returned NULL in this case. This has | |
8851 | caused some confusion to Windows users who haven't defined $HOME. | |
8852 | Thus RAND_file_name() is changed again: e_os.h can define a | |
8853 | DEFAULT_HOME, which will be used if $HOME is not set. | |
8854 | For Windows, we use "C:"; on other platforms, we still require | |
8855 | environment variables. | |
8856 | ||
8857 | *) Move 'if (!initialized) RAND_poll()' into regions protected by | |
8858 | CRYPTO_LOCK_RAND. This is not strictly necessary, but avoids | |
8859 | having multiple threads call RAND_poll() concurrently. | |
8860 | [Bodo Moeller] | |
8861 | ||
8862 | *) In crypto/rand/md_rand.c, replace 'add_do_not_lock' flag by a | |
8863 | combination of a flag and a thread ID variable. | |
8864 | Otherwise while one thread is in ssleay_rand_bytes (which sets the | |
8865 | flag), *other* threads can enter ssleay_add_bytes without obeying | |
8866 | the CRYPTO_LOCK_RAND lock (and may even illegally release the lock | |
8867 | that they do not hold after the first thread unsets add_do_not_lock). | |
8868 | [Bodo Moeller] | |
8869 | ||
8870 | *) Change bctest again: '-x' expressions are not available in all | |
8871 | versions of 'test'. | |
8872 | [Bodo Moeller] | |
8873 | ||
8874 | Changes between 0.9.6 and 0.9.6a [5 Apr 2001] | |
8875 | ||
8876 | *) Fix a couple of memory leaks in PKCS7_dataDecode() | |
8877 | [Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>] | |
8878 | ||
8879 | *) Change Configure and Makefiles to provide EXE_EXT, which will contain | |
8880 | the default extension for executables, if any. Also, make the perl | |
8881 | scripts that use symlink() to test if it really exists and use "cp" | |
8882 | if it doesn't. All this made OpenSSL compilable and installable in | |
8883 | CygWin. | |
8884 | [Richard Levitte] | |
8885 | ||
8886 | *) Fix for asn1_GetSequence() for indefinite length constructed data. | |
8887 | If SEQUENCE is length is indefinite just set c->slen to the total | |
8888 | amount of data available. | |
8889 | [Steve Henson, reported by shige@FreeBSD.org] | |
8890 | [This change does not apply to 0.9.7.] | |
8891 | ||
8892 | *) Change bctest to avoid here-documents inside command substitution | |
8893 | (workaround for FreeBSD /bin/sh bug). | |
8894 | For compatibility with Ultrix, avoid shell functions (introduced | |
8895 | in the bctest version that searches along $PATH). | |
8896 | [Bodo Moeller] | |
8897 | ||
8898 | *) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes | |
8899 | with des_encrypt() defined on some operating systems, like Solaris | |
8900 | and UnixWare. | |
8901 | [Richard Levitte] | |
8902 | ||
8903 | *) Check the result of RSA-CRT (see D. Boneh, R. DeMillo, R. Lipton: | |
8904 | On the Importance of Eliminating Errors in Cryptographic | |
8905 | Computations, J. Cryptology 14 (2001) 2, 101-119, | |
8906 | http://theory.stanford.edu/~dabo/papers/faults.ps.gz). | |
8907 | [Ulf Moeller] | |
8908 | ||
8909 | *) MIPS assembler BIGNUM division bug fix. | |
8910 | [Andy Polyakov] | |
8911 | ||
8912 | *) Disabled incorrect Alpha assembler code. | |
8913 | [Richard Levitte] | |
8914 | ||
8915 | *) Fix PKCS#7 decode routines so they correctly update the length | |
8916 | after reading an EOC for the EXPLICIT tag. | |
8917 | [Steve Henson] | |
8918 | [This change does not apply to 0.9.7.] | |
8919 | ||
8920 | *) Fix bug in PKCS#12 key generation routines. This was triggered | |
8921 | if a 3DES key was generated with a 0 initial byte. Include | |
8922 | PKCS12_BROKEN_KEYGEN compilation option to retain the old | |
8923 | (but broken) behaviour. | |
8924 | [Steve Henson] | |
8925 | ||
8926 | *) Enhance bctest to search for a working bc along $PATH and print | |
8927 | it when found. | |
8928 | [Tim Rice <tim@multitalents.net> via Richard Levitte] | |
8929 | ||
8930 | *) Fix memory leaks in err.c: free err_data string if necessary; | |
8931 | don't write to the wrong index in ERR_set_error_data. | |
8932 | [Bodo Moeller] | |
8933 | ||
8934 | *) Implement ssl23_peek (analogous to ssl23_read), which previously | |
8935 | did not exist. | |
8936 | [Bodo Moeller] | |
8937 | ||
8938 | *) Replace rdtsc with _emit statements for VC++ version 5. | |
8939 | [Jeremy Cooper <jeremy@baymoo.org>] | |
8940 | ||
8941 | *) Make it possible to reuse SSLv2 sessions. | |
8942 | [Richard Levitte] | |
8943 | ||
8944 | *) In copy_email() check for >= 0 as a return value for | |
8945 | X509_NAME_get_index_by_NID() since 0 is a valid index. | |
8946 | [Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>] | |
8947 | ||
8948 | *) Avoid coredump with unsupported or invalid public keys by checking if | |
8949 | X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when | |
8950 | PKCS7_verify() fails with non detached data. | |
8951 | [Steve Henson] | |
8952 | ||
8953 | *) Don't use getenv in library functions when run as setuid/setgid. | |
8954 | New function OPENSSL_issetugid(). | |
8955 | [Ulf Moeller] | |
8956 | ||
8957 | *) Avoid false positives in memory leak detection code (crypto/mem_dbg.c) | |
8958 | due to incorrect handling of multi-threading: | |
8959 | ||
8960 | 1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl(). | |
8961 | ||
8962 | 2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on(). | |
8963 | ||
8964 | 3. Count how many times MemCheck_off() has been called so that | |
8965 | nested use can be treated correctly. This also avoids | |
8966 | inband-signalling in the previous code (which relied on the | |
8967 | assumption that thread ID 0 is impossible). | |
8968 | [Bodo Moeller] | |
8969 | ||
8970 | *) Add "-rand" option also to s_client and s_server. | |
8971 | [Lutz Jaenicke] | |
8972 | ||
8973 | *) Fix CPU detection on Irix 6.x. | |
8974 | [Kurt Hockenbury <khockenb@stevens-tech.edu> and | |
8975 | "Bruce W. Forsberg" <bruce.forsberg@baesystems.com>] | |
8976 | ||
8977 | *) Fix X509_NAME bug which produced incorrect encoding if X509_NAME | |
8978 | was empty. | |
8979 | [Steve Henson] | |
8980 | [This change does not apply to 0.9.7.] | |
8981 | ||
8982 | *) Use the cached encoding of an X509_NAME structure rather than | |
8983 | copying it. This is apparently the reason for the libsafe "errors" | |
8984 | but the code is actually correct. | |
8985 | [Steve Henson] | |
8986 | ||
8987 | *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent | |
8988 | Bleichenbacher's DSA attack. | |
8989 | Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits | |
8990 | to be set and top=0 forces the highest bit to be set; top=-1 is new | |
8991 | and leaves the highest bit random. | |
8992 | [Ulf Moeller, Bodo Moeller] | |
8993 | ||
8994 | *) In the NCONF_...-based implementations for CONF_... queries | |
8995 | (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using | |
8996 | a temporary CONF structure with the data component set to NULL | |
8997 | (which gives segmentation faults in lh_retrieve). | |
8998 | Instead, use NULL for the CONF pointer in CONF_get_string and | |
8999 | CONF_get_number (which may use environment variables) and directly | |
9000 | return NULL from CONF_get_section. | |
9001 | [Bodo Moeller] | |
9002 | ||
9003 | *) Fix potential buffer overrun for EBCDIC. | |
9004 | [Ulf Moeller] | |
9005 | ||
9006 | *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign | |
9007 | keyUsage if basicConstraints absent for a CA. | |
9008 | [Steve Henson] | |
9009 | ||
9010 | *) Make SMIME_write_PKCS7() write mail header values with a format that | |
9011 | is more generally accepted (no spaces before the semicolon), since | |
9012 | some programs can't parse those values properly otherwise. Also make | |
9013 | sure BIO's that break lines after each write do not create invalid | |
9014 | headers. | |
9015 | [Richard Levitte] | |
9016 | ||
9017 | *) Make the CRL encoding routines work with empty SEQUENCE OF. The | |
9018 | macros previously used would not encode an empty SEQUENCE OF | |
9019 | and break the signature. | |
9020 | [Steve Henson] | |
9021 | [This change does not apply to 0.9.7.] | |
9022 | ||
9023 | *) Zero the premaster secret after deriving the master secret in | |
9024 | DH ciphersuites. | |
9025 | [Steve Henson] | |
9026 | ||
9027 | *) Add some EVP_add_digest_alias registrations (as found in | |
9028 | OpenSSL_add_all_digests()) to SSL_library_init() | |
9029 | aka OpenSSL_add_ssl_algorithms(). This provides improved | |
9030 | compatibility with peers using X.509 certificates | |
9031 | with unconventional AlgorithmIdentifier OIDs. | |
9032 | [Bodo Moeller] | |
9033 | ||
9034 | *) Fix for Irix with NO_ASM. | |
9035 | ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>] | |
9036 | ||
9037 | *) ./config script fixes. | |
9038 | [Ulf Moeller, Richard Levitte] | |
9039 | ||
9040 | *) Fix 'openssl passwd -1'. | |
9041 | [Bodo Moeller] | |
9042 | ||
9043 | *) Change PKCS12_key_gen_asc() so it can cope with non null | |
9044 | terminated strings whose length is passed in the passlen | |
9045 | parameter, for example from PEM callbacks. This was done | |
9046 | by adding an extra length parameter to asc2uni(). | |
9047 | [Steve Henson, reported by <oddissey@samsung.co.kr>] | |
9048 | ||
9049 | *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn | |
9050 | call failed, free the DSA structure. | |
9051 | [Bodo Moeller] | |
9052 | ||
9053 | *) Fix to uni2asc() to cope with zero length Unicode strings. | |
9054 | These are present in some PKCS#12 files. | |
9055 | [Steve Henson] | |
9056 | ||
9057 | *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c). | |
9058 | Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits | |
9059 | when writing a 32767 byte record. | |
9060 | [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>] | |
9061 | ||
9062 | *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c), | |
9063 | obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}. | |
9064 | ||
9065 | (RSA objects have a reference count access to which is protected | |
9066 | by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c], | |
9067 | so they are meant to be shared between threads.) | |
9068 | [Bodo Moeller, Geoff Thorpe; original patch submitted by | |
9069 | "Reddie, Steven" <Steven.Reddie@ca.com>] | |
9070 | ||
9071 | *) Fix a deadlock in CRYPTO_mem_leaks(). | |
9072 | [Bodo Moeller] | |
9073 | ||
9074 | *) Use better test patterns in bntest. | |
9075 | [Ulf Möller] | |
9076 | ||
9077 | *) rand_win.c fix for Borland C. | |
9078 | [Ulf Möller] | |
9079 | ||
9080 | *) BN_rshift bugfix for n == 0. | |
9081 | [Bodo Moeller] | |
9082 | ||
9083 | *) Add a 'bctest' script that checks for some known 'bc' bugs | |
9084 | so that 'make test' does not abort just because 'bc' is broken. | |
9085 | [Bodo Moeller] | |
9086 | ||
9087 | *) Store verify_result within SSL_SESSION also for client side to | |
9088 | avoid potential security hole. (Re-used sessions on the client side | |
9089 | always resulted in verify_result==X509_V_OK, not using the original | |
9090 | result of the server certificate verification.) | |
9091 | [Lutz Jaenicke] | |
9092 | ||
9093 | *) Fix ssl3_pending: If the record in s->s3->rrec is not of type | |
9094 | SSL3_RT_APPLICATION_DATA, return 0. | |
9095 | Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true. | |
9096 | [Bodo Moeller] | |
9097 | ||
9098 | *) Fix SSL_peek: | |
9099 | Both ssl2_peek and ssl3_peek, which were totally broken in earlier | |
9100 | releases, have been re-implemented by renaming the previous | |
9101 | implementations of ssl2_read and ssl3_read to ssl2_read_internal | |
9102 | and ssl3_read_internal, respectively, and adding 'peek' parameters | |
9103 | to them. The new ssl[23]_{read,peek} functions are calls to | |
9104 | ssl[23]_read_internal with the 'peek' flag set appropriately. | |
9105 | A 'peek' parameter has also been added to ssl3_read_bytes, which | |
9106 | does the actual work for ssl3_read_internal. | |
9107 | [Bodo Moeller] | |
9108 | ||
9109 | *) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling | |
9110 | the method-specific "init()" handler. Also clean up ex_data after | |
9111 | calling the method-specific "finish()" handler. Previously, this was | |
9112 | happening the other way round. | |
9113 | [Geoff Thorpe] | |
9114 | ||
9115 | *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16. | |
9116 | The previous value, 12, was not always sufficient for BN_mod_exp(). | |
9117 | [Bodo Moeller] | |
9118 | ||
9119 | *) Make sure that shared libraries get the internal name engine with | |
9120 | the full version number and not just 0. This should mark the | |
9121 | shared libraries as not backward compatible. Of course, this should | |
9122 | be changed again when we can guarantee backward binary compatibility. | |
9123 | [Richard Levitte] | |
9124 | ||
9125 | *) Fix typo in get_cert_by_subject() in by_dir.c | |
9126 | [Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>] | |
9127 | ||
9128 | *) Rework the system to generate shared libraries: | |
9129 | ||
9130 | - Make note of the expected extension for the shared libraries and | |
9131 | if there is a need for symbolic links from for example libcrypto.so.0 | |
9132 | to libcrypto.so.0.9.7. There is extended info in Configure for | |
9133 | that. | |
9134 | ||
9135 | - Make as few rebuilds of the shared libraries as possible. | |
9136 | ||
9137 | - Still avoid linking the OpenSSL programs with the shared libraries. | |
9138 | ||
9139 | - When installing, install the shared libraries separately from the | |
9140 | static ones. | |
9141 | [Richard Levitte] | |
9142 | ||
9143 | *) Fix SSL_CTX_set_read_ahead macro to actually use its argument. | |
9144 | ||
9145 | Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new | |
9146 | and not in SSL_clear because the latter is also used by the | |
9147 | accept/connect functions; previously, the settings made by | |
9148 | SSL_set_read_ahead would be lost during the handshake. | |
9149 | [Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>] | |
9150 | ||
9151 | *) Correct util/mkdef.pl to be selective about disabled algorithms. | |
9152 | Previously, it would create entries for disabled algorithms no | |
9153 | matter what. | |
9154 | [Richard Levitte] | |
9155 | ||
9156 | *) Added several new manual pages for SSL_* function. | |
9157 | [Lutz Jaenicke] | |
9158 | ||
9159 | Changes between 0.9.5a and 0.9.6 [24 Sep 2000] | |
9160 | ||
9161 | *) In ssl23_get_client_hello, generate an error message when faced | |
9162 | with an initial SSL 3.0/TLS record that is too small to contain the | |
9163 | first two bytes of the ClientHello message, i.e. client_version. | |
9164 | (Note that this is a pathologic case that probably has never happened | |
9165 | in real life.) The previous approach was to use the version number | |
9166 | from the record header as a substitute; but our protocol choice | |
9167 | should not depend on that one because it is not authenticated | |
9168 | by the Finished messages. | |
9169 | [Bodo Moeller] | |
9170 | ||
9171 | *) More robust randomness gathering functions for Windows. | |
9172 | [Jeffrey Altman <jaltman@columbia.edu>] | |
9173 | ||
9174 | *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is | |
9175 | not set then we don't setup the error code for issuer check errors | |
9176 | to avoid possibly overwriting other errors which the callback does | |
9177 | handle. If an application does set the flag then we assume it knows | |
9178 | what it is doing and can handle the new informational codes | |
9179 | appropriately. | |
9180 | [Steve Henson] | |
9181 | ||
9182 | *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for | |
9183 | a general "ANY" type, as such it should be able to decode anything | |
9184 | including tagged types. However it didn't check the class so it would | |
9185 | wrongly interpret tagged types in the same way as their universal | |
9186 | counterpart and unknown types were just rejected. Changed so that the | |
9187 | tagged and unknown types are handled in the same way as a SEQUENCE: | |
9188 | that is the encoding is stored intact. There is also a new type | |
9189 | "V_ASN1_OTHER" which is used when the class is not universal, in this | |
9190 | case we have no idea what the actual type is so we just lump them all | |
9191 | together. | |
9192 | [Steve Henson] | |
9193 | ||
9194 | *) On VMS, stdout may very well lead to a file that is written to | |
9195 | in a record-oriented fashion. That means that every write() will | |
9196 | write a separate record, which will be read separately by the | |
9197 | programs trying to read from it. This can be very confusing. | |
9198 | ||
9199 | The solution is to put a BIO filter in the way that will buffer | |
9200 | text until a linefeed is reached, and then write everything a | |
9201 | line at a time, so every record written will be an actual line, | |
9202 | not chunks of lines and not (usually doesn't happen, but I've | |
9203 | seen it once) several lines in one record. BIO_f_linebuffer() is | |
9204 | the answer. | |
9205 | ||
9206 | Currently, it's a VMS-only method, because that's where it has | |
9207 | been tested well enough. | |
9208 | [Richard Levitte] | |
9209 | ||
9210 | *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery, | |
9211 | it can return incorrect results. | |
9212 | (Note: The buggy variant was not enabled in OpenSSL 0.9.5a, | |
9213 | but it was in 0.9.6-beta[12].) | |
9214 | [Bodo Moeller] | |
9215 | ||
9216 | *) Disable the check for content being present when verifying detached | |
9217 | signatures in pk7_smime.c. Some versions of Netscape (wrongly) | |
9218 | include zero length content when signing messages. | |
9219 | [Steve Henson] | |
9220 | ||
9221 | *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR | |
9222 | BIO_ctrl (for BIO pairs). | |
9223 | [Bodo Möller] | |
9224 | ||
9225 | *) Add DSO method for VMS. | |
9226 | [Richard Levitte] | |
9227 | ||
9228 | *) Bug fix: Montgomery multiplication could produce results with the | |
9229 | wrong sign. | |
9230 | [Ulf Möller] | |
9231 | ||
9232 | *) Add RPM specification openssl.spec and modify it to build three | |
9233 | packages. The default package contains applications, application | |
9234 | documentation and run-time libraries. The devel package contains | |
9235 | include files, static libraries and function documentation. The | |
9236 | doc package contains the contents of the doc directory. The original | |
9237 | openssl.spec was provided by Damien Miller <djm@mindrot.org>. | |
9238 | [Richard Levitte] | |
9239 | ||
9240 | *) Add a large number of documentation files for many SSL routines. | |
9241 | [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>] | |
9242 | ||
9243 | *) Add a configuration entry for Sony News 4. | |
9244 | [NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>] | |
9245 | ||
9246 | *) Don't set the two most significant bits to one when generating a | |
9247 | random number < q in the DSA library. | |
9248 | [Ulf Möller] | |
9249 | ||
9250 | *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default | |
9251 | behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if | |
9252 | the underlying transport is blocking) if a handshake took place. | |
9253 | (The default behaviour is needed by applications such as s_client | |
9254 | and s_server that use select() to determine when to use SSL_read; | |
9255 | but for applications that know in advance when to expect data, it | |
9256 | just makes things more complicated.) | |
9257 | [Bodo Moeller] | |
9258 | ||
9259 | *) Add RAND_egd_bytes(), which gives control over the number of bytes read | |
9260 | from EGD. | |
9261 | [Ben Laurie] | |
9262 | ||
9263 | *) Add a few more EBCDIC conditionals that make `req' and `x509' | |
9264 | work better on such systems. | |
9265 | [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>] | |
9266 | ||
9267 | *) Add two demo programs for PKCS12_parse() and PKCS12_create(). | |
9268 | Update PKCS12_parse() so it copies the friendlyName and the | |
9269 | keyid to the certificates aux info. | |
9270 | [Steve Henson] | |
9271 | ||
9272 | *) Fix bug in PKCS7_verify() which caused an infinite loop | |
9273 | if there was more than one signature. | |
9274 | [Sven Uszpelkat <su@celocom.de>] | |
9275 | ||
9276 | *) Major change in util/mkdef.pl to include extra information | |
9277 | about each symbol, as well as presenting variables as well | |
9278 | as functions. This change means that there's n more need | |
9279 | to rebuild the .num files when some algorithms are excluded. | |
9280 | [Richard Levitte] | |
9281 | ||
9282 | *) Allow the verify time to be set by an application, | |
9283 | rather than always using the current time. | |
9284 | [Steve Henson] | |
9285 | ||
9286 | *) Phase 2 verify code reorganisation. The certificate | |
9287 | verify code now looks up an issuer certificate by a | |
9288 | number of criteria: subject name, authority key id | |
9289 | and key usage. It also verifies self signed certificates | |
9290 | by the same criteria. The main comparison function is | |
9291 | X509_check_issued() which performs these checks. | |
9292 | ||
9293 | Lot of changes were necessary in order to support this | |
9294 | without completely rewriting the lookup code. | |
9295 | ||
9296 | Authority and subject key identifier are now cached. | |
9297 | ||
9298 | The LHASH 'certs' is X509_STORE has now been replaced | |
9299 | by a STACK_OF(X509_OBJECT). This is mainly because an | |
9300 | LHASH can't store or retrieve multiple objects with | |
9301 | the same hash value. | |
9302 | ||
9303 | As a result various functions (which were all internal | |
9304 | use only) have changed to handle the new X509_STORE | |
9305 | structure. This will break anything that messed round | |
9306 | with X509_STORE internally. | |
9307 | ||
9308 | The functions X509_STORE_add_cert() now checks for an | |
9309 | exact match, rather than just subject name. | |
9310 | ||
9311 | The X509_STORE API doesn't directly support the retrieval | |
9312 | of multiple certificates matching a given criteria, however | |
9313 | this can be worked round by performing a lookup first | |
9314 | (which will fill the cache with candidate certificates) | |
9315 | and then examining the cache for matches. This is probably | |
9316 | the best we can do without throwing out X509_LOOKUP | |
9317 | entirely (maybe later...). | |
9318 | ||
9319 | The X509_VERIFY_CTX structure has been enhanced considerably. | |
9320 | ||
9321 | All certificate lookup operations now go via a get_issuer() | |
9322 | callback. Although this currently uses an X509_STORE it | |
9323 | can be replaced by custom lookups. This is a simple way | |
9324 | to bypass the X509_STORE hackery necessary to make this | |
9325 | work and makes it possible to use more efficient techniques | |
9326 | in future. A very simple version which uses a simple | |
9327 | STACK for its trusted certificate store is also provided | |
9328 | using X509_STORE_CTX_trusted_stack(). | |
9329 | ||
9330 | The verify_cb() and verify() callbacks now have equivalents | |
9331 | in the X509_STORE_CTX structure. | |
9332 | ||
9333 | X509_STORE_CTX also has a 'flags' field which can be used | |
9334 | to customise the verify behaviour. | |
9335 | [Steve Henson] | |
9336 | ||
9337 | *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which | |
9338 | excludes S/MIME capabilities. | |
9339 | [Steve Henson] | |
9340 | ||
9341 | *) When a certificate request is read in keep a copy of the | |
9342 | original encoding of the signed data and use it when outputting | |
9343 | again. Signatures then use the original encoding rather than | |
9344 | a decoded, encoded version which may cause problems if the | |
9345 | request is improperly encoded. | |
9346 | [Steve Henson] | |
9347 | ||
9348 | *) For consistency with other BIO_puts implementations, call | |
9349 | buffer_write(b, ...) directly in buffer_puts instead of calling | |
9350 | BIO_write(b, ...). | |
9351 | ||
9352 | In BIO_puts, increment b->num_write as in BIO_write. | |
9353 | [Peter.Sylvester@EdelWeb.fr] | |
9354 | ||
9355 | *) Fix BN_mul_word for the case where the word is 0. (We have to use | |
9356 | BN_zero, we may not return a BIGNUM with an array consisting of | |
9357 | words set to zero.) | |
9358 | [Bodo Moeller] | |
9359 | ||
9360 | *) Avoid calling abort() from within the library when problems are | |
9361 | detected, except if preprocessor symbols have been defined | |
9362 | (such as REF_CHECK, BN_DEBUG etc.). | |
9363 | [Bodo Moeller] | |
9364 | ||
9365 | *) New openssl application 'rsautl'. This utility can be | |
9366 | used for low level RSA operations. DER public key | |
9367 | BIO/fp routines also added. | |
9368 | [Steve Henson] | |
9369 | ||
9370 | *) New Configure entry and patches for compiling on QNX 4. | |
9371 | [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>] | |
9372 | ||
9373 | *) A demo state-machine implementation was sponsored by | |
9374 | Nuron (http://www.nuron.com/) and is now available in | |
9375 | demos/state_machine. | |
9376 | [Ben Laurie] | |
9377 | ||
9378 | *) New options added to the 'dgst' utility for signature | |
9379 | generation and verification. | |
9380 | [Steve Henson] | |
9381 | ||
9382 | *) Unrecognized PKCS#7 content types are now handled via a | |
9383 | catch all ASN1_TYPE structure. This allows unsupported | |
9384 | types to be stored as a "blob" and an application can | |
9385 | encode and decode it manually. | |
9386 | [Steve Henson] | |
9387 | ||
9388 | *) Fix various signed/unsigned issues to make a_strex.c | |
9389 | compile under VC++. | |
9390 | [Oscar Jacobsson <oscar.jacobsson@celocom.com>] | |
9391 | ||
9392 | *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct | |
9393 | length if passed a buffer. ASN1_INTEGER_to_BN failed | |
9394 | if passed a NULL BN and its argument was negative. | |
9395 | [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>] | |
9396 | ||
9397 | *) Modification to PKCS#7 encoding routines to output definite | |
9398 | length encoding. Since currently the whole structures are in | |
9399 | memory there's not real point in using indefinite length | |
9400 | constructed encoding. However if OpenSSL is compiled with | |
9401 | the flag PKCS7_INDEFINITE_ENCODING the old form is used. | |
9402 | [Steve Henson] | |
9403 | ||
9404 | *) Added BIO_vprintf() and BIO_vsnprintf(). | |
9405 | [Richard Levitte] | |
9406 | ||
9407 | *) Added more prefixes to parse for in the the strings written | |
9408 | through a logging bio, to cover all the levels that are available | |
9409 | through syslog. The prefixes are now: | |
9410 | ||
9411 | PANIC, EMERG, EMR => LOG_EMERG | |
9412 | ALERT, ALR => LOG_ALERT | |
9413 | CRIT, CRI => LOG_CRIT | |
9414 | ERROR, ERR => LOG_ERR | |
9415 | WARNING, WARN, WAR => LOG_WARNING | |
9416 | NOTICE, NOTE, NOT => LOG_NOTICE | |
9417 | INFO, INF => LOG_INFO | |
9418 | DEBUG, DBG => LOG_DEBUG | |
9419 | ||
9420 | and as before, if none of those prefixes are present at the | |
9421 | beginning of the string, LOG_ERR is chosen. | |
9422 | ||
9423 | On Win32, the LOG_* levels are mapped according to this: | |
9424 | ||
9425 | LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE | |
9426 | LOG_WARNING => EVENTLOG_WARNING_TYPE | |
9427 | LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE | |
9428 | ||
9429 | [Richard Levitte] | |
9430 | ||
9431 | *) Made it possible to reconfigure with just the configuration | |
9432 | argument "reconf" or "reconfigure". The command line arguments | |
9433 | are stored in Makefile.ssl in the variable CONFIGURE_ARGS, | |
9434 | and are retrieved from there when reconfiguring. | |
9435 | [Richard Levitte] | |
9436 | ||
9437 | *) MD4 implemented. | |
9438 | [Assar Westerlund <assar@sics.se>, Richard Levitte] | |
9439 | ||
9440 | *) Add the arguments -CAfile and -CApath to the pkcs12 utility. | |
9441 | [Richard Levitte] | |
9442 | ||
9443 | *) The obj_dat.pl script was messing up the sorting of object | |
9444 | names. The reason was that it compared the quoted version | |
9445 | of strings as a result "OCSP" > "OCSP Signing" because | |
9446 | " > SPACE. Changed script to store unquoted versions of | |
9447 | names and add quotes on output. It was also omitting some | |
9448 | names from the lookup table if they were given a default | |
9449 | value (that is if SN is missing it is given the same | |
9450 | value as LN and vice versa), these are now added on the | |
9451 | grounds that if an object has a name we should be able to | |
9452 | look it up. Finally added warning output when duplicate | |
9453 | short or long names are found. | |
9454 | [Steve Henson] | |
9455 | ||
9456 | *) Changes needed for Tandem NSK. | |
9457 | [Scott Uroff <scott@xypro.com>] | |
9458 | ||
9459 | *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in | |
9460 | RSA_padding_check_SSLv23(), special padding was never detected | |
9461 | and thus the SSL 3.0/TLS 1.0 countermeasure against protocol | |
9462 | version rollback attacks was not effective. | |
9463 | ||
9464 | In s23_clnt.c, don't use special rollback-attack detection padding | |
9465 | (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the | |
9466 | client; similarly, in s23_srvr.c, don't do the rollback check if | |
9467 | SSL 2.0 is the only protocol enabled in the server. | |
9468 | [Bodo Moeller] | |
9469 | ||
9470 | *) Make it possible to get hexdumps of unprintable data with 'openssl | |
9471 | asn1parse'. By implication, the functions ASN1_parse_dump() and | |
9472 | BIO_dump_indent() are added. | |
9473 | [Richard Levitte] | |
9474 | ||
9475 | *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex() | |
9476 | these print out strings and name structures based on various | |
9477 | flags including RFC2253 support and proper handling of | |
9478 | multibyte characters. Added options to the 'x509' utility | |
9479 | to allow the various flags to be set. | |
9480 | [Steve Henson] | |
9481 | ||
9482 | *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME. | |
9483 | Also change the functions X509_cmp_current_time() and | |
9484 | X509_gmtime_adj() work with an ASN1_TIME structure, | |
9485 | this will enable certificates using GeneralizedTime in validity | |
9486 | dates to be checked. | |
9487 | [Steve Henson] | |
9488 | ||
9489 | *) Make the NEG_PUBKEY_BUG code (which tolerates invalid | |
9490 | negative public key encodings) on by default, | |
9491 | NO_NEG_PUBKEY_BUG can be set to disable it. | |
9492 | [Steve Henson] | |
9493 | ||
9494 | *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT | |
9495 | content octets. An i2c_ASN1_OBJECT is unnecessary because | |
9496 | the encoding can be trivially obtained from the structure. | |
9497 | [Steve Henson] | |
9498 | ||
9499 | *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock), | |
9500 | not read locks (CRYPTO_r_[un]lock). | |
9501 | [Bodo Moeller] | |
9502 | ||
9503 | *) A first attempt at creating official support for shared | |
9504 | libraries through configuration. I've kept it so the | |
9505 | default is static libraries only, and the OpenSSL programs | |
9506 | are always statically linked for now, but there are | |
9507 | preparations for dynamic linking in place. | |
9508 | This has been tested on Linux and Tru64. | |
9509 | [Richard Levitte] | |
9510 | ||
9511 | *) Randomness polling function for Win9x, as described in: | |
9512 | Peter Gutmann, Software Generation of Practically Strong | |
9513 | Random Numbers. | |
9514 | [Ulf Möller] | |
9515 | ||
9516 | *) Fix so PRNG is seeded in req if using an already existing | |
9517 | DSA key. | |
9518 | [Steve Henson] | |
9519 | ||
9520 | *) New options to smime application. -inform and -outform | |
9521 | allow alternative formats for the S/MIME message including | |
9522 | PEM and DER. The -content option allows the content to be | |
9523 | specified separately. This should allow things like Netscape | |
9524 | form signing output easier to verify. | |
9525 | [Steve Henson] | |
9526 | ||
9527 | *) Fix the ASN1 encoding of tags using the 'long form'. | |
9528 | [Steve Henson] | |
9529 | ||
9530 | *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT | |
9531 | STRING types. These convert content octets to and from the | |
9532 | underlying type. The actual tag and length octets are | |
9533 | already assumed to have been read in and checked. These | |
9534 | are needed because all other string types have virtually | |
9535 | identical handling apart from the tag. By having versions | |
9536 | of the ASN1 functions that just operate on content octets | |
9537 | IMPLICIT tagging can be handled properly. It also allows | |
9538 | the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED | |
9539 | and ASN1_INTEGER are identical apart from the tag. | |
9540 | [Steve Henson] | |
9541 | ||
9542 | *) Change the handling of OID objects as follows: | |
9543 | ||
9544 | - New object identifiers are inserted in objects.txt, following | |
9545 | the syntax given in objects.README. | |
9546 | - objects.pl is used to process obj_mac.num and create a new | |
9547 | obj_mac.h. | |
9548 | - obj_dat.pl is used to create a new obj_dat.h, using the data in | |
9549 | obj_mac.h. | |
9550 | ||
9551 | This is currently kind of a hack, and the perl code in objects.pl | |
9552 | isn't very elegant, but it works as I intended. The simplest way | |
9553 | to check that it worked correctly is to look in obj_dat.h and | |
9554 | check the array nid_objs and make sure the objects haven't moved | |
9555 | around (this is important!). Additions are OK, as well as | |
9556 | consistent name changes. | |
9557 | [Richard Levitte] | |
9558 | ||
9559 | *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1'). | |
9560 | [Bodo Moeller] | |
9561 | ||
9562 | *) Addition of the command line parameter '-rand file' to 'openssl req'. | |
9563 | The given file adds to whatever has already been seeded into the | |
9564 | random pool through the RANDFILE configuration file option or | |
9565 | environment variable, or the default random state file. | |
9566 | [Richard Levitte] | |
9567 | ||
9568 | *) mkstack.pl now sorts each macro group into lexical order. | |
9569 | Previously the output order depended on the order the files | |
9570 | appeared in the directory, resulting in needless rewriting | |
9571 | of safestack.h . | |
9572 | [Steve Henson] | |
9573 | ||
9574 | *) Patches to make OpenSSL compile under Win32 again. Mostly | |
9575 | work arounds for the VC++ problem that it treats func() as | |
9576 | func(void). Also stripped out the parts of mkdef.pl that | |
9577 | added extra typesafe functions: these no longer exist. | |
9578 | [Steve Henson] | |
9579 | ||
9580 | *) Reorganisation of the stack code. The macros are now all | |
9581 | collected in safestack.h . Each macro is defined in terms of | |
9582 | a "stack macro" of the form SKM_<name>(type, a, b). The | |
9583 | DEBUG_SAFESTACK is now handled in terms of function casts, | |
9584 | this has the advantage of retaining type safety without the | |
9585 | use of additional functions. If DEBUG_SAFESTACK is not defined | |
9586 | then the non typesafe macros are used instead. Also modified the | |
9587 | mkstack.pl script to handle the new form. Needs testing to see | |
9588 | if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK | |
9589 | the default if no major problems. Similar behaviour for ASN1_SET_OF | |
9590 | and PKCS12_STACK_OF. | |
9591 | [Steve Henson] | |
9592 | ||
9593 | *) When some versions of IIS use the 'NET' form of private key the | |
9594 | key derivation algorithm is different. Normally MD5(password) is | |
9595 | used as a 128 bit RC4 key. In the modified case | |
9596 | MD5(MD5(password) + "SGCKEYSALT") is used instead. Added some | |
9597 | new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same | |
9598 | as the old Netscape_RSA functions except they have an additional | |
9599 | 'sgckey' parameter which uses the modified algorithm. Also added | |
9600 | an -sgckey command line option to the rsa utility. Thanks to | |
9601 | Adrian Peck <bertie@ncipher.com> for posting details of the modified | |
9602 | algorithm to openssl-dev. | |
9603 | [Steve Henson] | |
9604 | ||
9605 | *) The evp_local.h macros were using 'c.##kname' which resulted in | |
9606 | invalid expansion on some systems (SCO 5.0.5 for example). | |
9607 | Corrected to 'c.kname'. | |
9608 | [Phillip Porch <root@theporch.com>] | |
9609 | ||
9610 | *) New X509_get1_email() and X509_REQ_get1_email() functions that return | |
9611 | a STACK of email addresses from a certificate or request, these look | |
9612 | in the subject name and the subject alternative name extensions and | |
9613 | omit any duplicate addresses. | |
9614 | [Steve Henson] | |
9615 | ||
9616 | *) Re-implement BN_mod_exp2_mont using independent (and larger) windows. | |
9617 | This makes DSA verification about 2 % faster. | |
9618 | [Bodo Moeller] | |
9619 | ||
9620 | *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5 | |
9621 | (meaning that now 2^5 values will be precomputed, which is only 4 KB | |
9622 | plus overhead for 1024 bit moduli). | |
9623 | This makes exponentiations about 0.5 % faster for 1024 bit | |
9624 | exponents (as measured by "openssl speed rsa2048"). | |
9625 | [Bodo Moeller] | |
9626 | ||
9627 | *) Rename memory handling macros to avoid conflicts with other | |
9628 | software: | |
9629 | Malloc => OPENSSL_malloc | |
9630 | Malloc_locked => OPENSSL_malloc_locked | |
9631 | Realloc => OPENSSL_realloc | |
9632 | Free => OPENSSL_free | |
9633 | [Richard Levitte] | |
9634 | ||
9635 | *) New function BN_mod_exp_mont_word for small bases (roughly 15% | |
9636 | faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange). | |
9637 | [Bodo Moeller] | |
9638 | ||
9639 | *) CygWin32 support. | |
9640 | [John Jarvie <jjarvie@newsguy.com>] | |
9641 | ||
9642 | *) The type-safe stack code has been rejigged. It is now only compiled | |
9643 | in when OpenSSL is configured with the DEBUG_SAFESTACK option and | |
9644 | by default all type-specific stack functions are "#define"d back to | |
9645 | standard stack functions. This results in more streamlined output | |
9646 | but retains the type-safety checking possibilities of the original | |
9647 | approach. | |
9648 | [Geoff Thorpe] | |
9649 | ||
9650 | *) The STACK code has been cleaned up, and certain type declarations | |
9651 | that didn't make a lot of sense have been brought in line. This has | |
9652 | also involved a cleanup of sorts in safestack.h to more correctly | |
9653 | map type-safe stack functions onto their plain stack counterparts. | |
9654 | This work has also resulted in a variety of "const"ifications of | |
9655 | lots of the code, especially "_cmp" operations which should normally | |
9656 | be prototyped with "const" parameters anyway. | |
9657 | [Geoff Thorpe] | |
9658 | ||
9659 | *) When generating bytes for the first time in md_rand.c, 'stir the pool' | |
9660 | by seeding with STATE_SIZE dummy bytes (with zero entropy count). | |
9661 | (The PRNG state consists of two parts, the large pool 'state' and 'md', | |
9662 | where all of 'md' is used each time the PRNG is used, but 'state' | |
9663 | is used only indexed by a cyclic counter. As entropy may not be | |
9664 | well distributed from the beginning, 'md' is important as a | |
9665 | chaining variable. However, the output function chains only half | |
9666 | of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains | |
9667 | all of 'md', and seeding with STATE_SIZE dummy bytes will result | |
9668 | in all of 'state' being rewritten, with the new values depending | |
9669 | on virtually all of 'md'. This overcomes the 80 bit limitation.) | |
9670 | [Bodo Moeller] | |
9671 | ||
9672 | *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when | |
9673 | the handshake is continued after ssl_verify_cert_chain(); | |
9674 | otherwise, if SSL_VERIFY_NONE is set, remaining error codes | |
9675 | can lead to 'unexplainable' connection aborts later. | |
9676 | [Bodo Moeller; problem tracked down by Lutz Jaenicke] | |
9677 | ||
9678 | *) Major EVP API cipher revision. | |
9679 | Add hooks for extra EVP features. This allows various cipher | |
9680 | parameters to be set in the EVP interface. Support added for variable | |
9681 | key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and | |
9682 | setting of RC2 and RC5 parameters. | |
9683 | ||
9684 | Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length | |
9685 | ciphers. | |
9686 | ||
9687 | Remove lots of duplicated code from the EVP library. For example *every* | |
9688 | cipher init() function handles the 'iv' in the same way according to the | |
9689 | cipher mode. They also all do nothing if the 'key' parameter is NULL and | |
9690 | for CFB and OFB modes they zero ctx->num. | |
9691 | ||
9692 | New functionality allows removal of S/MIME code RC2 hack. | |
9693 | ||
9694 | Most of the routines have the same form and so can be declared in terms | |
9695 | of macros. | |
9696 | ||
9697 | By shifting this to the top level EVP_CipherInit() it can be removed from | |
9698 | all individual ciphers. If the cipher wants to handle IVs or keys | |
9699 | differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT | |
9700 | flags. | |
9701 | ||
9702 | Change lots of functions like EVP_EncryptUpdate() to now return a | |
9703 | value: although software versions of the algorithms cannot fail | |
9704 | any installed hardware versions can. | |
9705 | [Steve Henson] | |
9706 | ||
9707 | *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if | |
9708 | this option is set, tolerate broken clients that send the negotiated | |
9709 | protocol version number instead of the requested protocol version | |
9710 | number. | |
9711 | [Bodo Moeller] | |
9712 | ||
9713 | *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag; | |
9714 | i.e. non-zero for export ciphersuites, zero otherwise. | |
9715 | Previous versions had this flag inverted, inconsistent with | |
9716 | rsa_tmp_cb (..._TMP_RSA_CB). | |
9717 | [Bodo Moeller; problem reported by Amit Chopra] | |
9718 | ||
9719 | *) Add missing DSA library text string. Work around for some IIS | |
9720 | key files with invalid SEQUENCE encoding. | |
9721 | [Steve Henson] | |
9722 | ||
9723 | *) Add a document (doc/standards.txt) that list all kinds of standards | |
9724 | and so on that are implemented in OpenSSL. | |
9725 | [Richard Levitte] | |
9726 | ||
9727 | *) Enhance c_rehash script. Old version would mishandle certificates | |
9728 | with the same subject name hash and wouldn't handle CRLs at all. | |
9729 | Added -fingerprint option to crl utility, to support new c_rehash | |
9730 | features. | |
9731 | [Steve Henson] | |
9732 | ||
9733 | *) Eliminate non-ANSI declarations in crypto.h and stack.h. | |
9734 | [Ulf Möller] | |
9735 | ||
9736 | *) Fix for SSL server purpose checking. Server checking was | |
9737 | rejecting certificates which had extended key usage present | |
9738 | but no ssl client purpose. | |
9739 | [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>] | |
9740 | ||
9741 | *) Make PKCS#12 code work with no password. The PKCS#12 spec | |
9742 | is a little unclear about how a blank password is handled. | |
9743 | Since the password in encoded as a BMPString with terminating | |
9744 | double NULL a zero length password would end up as just the | |
9745 | double NULL. However no password at all is different and is | |
9746 | handled differently in the PKCS#12 key generation code. NS | |
9747 | treats a blank password as zero length. MSIE treats it as no | |
9748 | password on export: but it will try both on import. We now do | |
9749 | the same: PKCS12_parse() tries zero length and no password if | |
9750 | the password is set to "" or NULL (NULL is now a valid password: | |
9751 | it wasn't before) as does the pkcs12 application. | |
9752 | [Steve Henson] | |
9753 | ||
9754 | *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use | |
9755 | perror when PEM_read_bio_X509_REQ fails, the error message must | |
9756 | be obtained from the error queue. | |
9757 | [Bodo Moeller] | |
9758 | ||
9759 | *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing | |
9760 | it in ERR_remove_state if appropriate, and change ERR_get_state | |
9761 | accordingly to avoid race conditions (this is necessary because | |
9762 | thread_hash is no longer constant once set). | |
9763 | [Bodo Moeller] | |
9764 | ||
9765 | *) Bugfix for linux-elf makefile.one. | |
9766 | [Ulf Möller] | |
9767 | ||
9768 | *) RSA_get_default_method() will now cause a default | |
9769 | RSA_METHOD to be chosen if one doesn't exist already. | |
9770 | Previously this was only set during a call to RSA_new() | |
9771 | or RSA_new_method(NULL) meaning it was possible for | |
9772 | RSA_get_default_method() to return NULL. | |
9773 | [Geoff Thorpe] | |
9774 | ||
9775 | *) Added native name translation to the existing DSO code | |
9776 | that will convert (if the flag to do so is set) filenames | |
9777 | that are sufficiently small and have no path information | |
9778 | into a canonical native form. Eg. "blah" converted to | |
9779 | "libblah.so" or "blah.dll" etc. | |
9780 | [Geoff Thorpe] | |
9781 | ||
9782 | *) New function ERR_error_string_n(e, buf, len) which is like | |
9783 | ERR_error_string(e, buf), but writes at most 'len' bytes | |
9784 | including the 0 terminator. For ERR_error_string_n, 'buf' | |
9785 | may not be NULL. | |
9786 | [Damien Miller <djm@mindrot.org>, Bodo Moeller] | |
9787 | ||
9788 | *) CONF library reworked to become more general. A new CONF | |
9789 | configuration file reader "class" is implemented as well as a | |
9790 | new functions (NCONF_*, for "New CONF") to handle it. The now | |
9791 | old CONF_* functions are still there, but are reimplemented to | |
9792 | work in terms of the new functions. Also, a set of functions | |
9793 | to handle the internal storage of the configuration data is | |
9794 | provided to make it easier to write new configuration file | |
9795 | reader "classes" (I can definitely see something reading a | |
9796 | configuration file in XML format, for example), called _CONF_*, | |
9797 | or "the configuration storage API"... | |
9798 | ||
9799 | The new configuration file reading functions are: | |
9800 | ||
9801 | NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio, | |
9802 | NCONF_get_section, NCONF_get_string, NCONF_get_numbre | |
9803 | ||
9804 | NCONF_default, NCONF_WIN32 | |
9805 | ||
9806 | NCONF_dump_fp, NCONF_dump_bio | |
9807 | ||
9808 | NCONF_default and NCONF_WIN32 are method (or "class") choosers, | |
9809 | NCONF_new creates a new CONF object. This works in the same way | |
9810 | as other interfaces in OpenSSL, like the BIO interface. | |
9811 | NCONF_dump_* dump the internal storage of the configuration file, | |
9812 | which is useful for debugging. All other functions take the same | |
9813 | arguments as the old CONF_* functions wth the exception of the | |
9814 | first that must be a `CONF *' instead of a `LHASH *'. | |
9815 | ||
9816 | To make it easer to use the new classes with the old CONF_* functions, | |
9817 | the function CONF_set_default_method is provided. | |
9818 | [Richard Levitte] | |
9819 | ||
9820 | *) Add '-tls1' option to 'openssl ciphers', which was already | |
9821 | mentioned in the documentation but had not been implemented. | |
9822 | (This option is not yet really useful because even the additional | |
9823 | experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.) | |
9824 | [Bodo Moeller] | |
9825 | ||
9826 | *) Initial DSO code added into libcrypto for letting OpenSSL (and | |
9827 | OpenSSL-based applications) load shared libraries and bind to | |
9828 | them in a portable way. | |
9829 | [Geoff Thorpe, with contributions from Richard Levitte] | |
9830 | ||
9831 | Changes between 0.9.5 and 0.9.5a [1 Apr 2000] | |
9832 | ||
9833 | *) Make sure _lrotl and _lrotr are only used with MSVC. | |
9834 | ||
9835 | *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status | |
9836 | (the default implementation of RAND_status). | |
9837 | ||
9838 | *) Rename openssl x509 option '-crlext', which was added in 0.9.5, | |
9839 | to '-clrext' (= clear extensions), as intended and documented. | |
9840 | [Bodo Moeller; inconsistency pointed out by Michael Attili | |
9841 | <attili@amaxo.com>] | |
9842 | ||
9843 | *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length | |
9844 | was larger than the MD block size. | |
9845 | [Steve Henson, pointed out by Yost William <YostW@tce.com>] | |
9846 | ||
9847 | *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument | |
9848 | fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set() | |
9849 | using the passed key: if the passed key was a private key the result | |
9850 | of X509_print(), for example, would be to print out all the private key | |
9851 | components. | |
9852 | [Steve Henson] | |
9853 | ||
9854 | *) des_quad_cksum() byte order bug fix. | |
9855 | [Ulf Möller, using the problem description in krb4-0.9.7, where | |
9856 | the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>] | |
9857 | ||
9858 | *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly | |
9859 | discouraged. | |
9860 | [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>] | |
9861 | ||
9862 | *) For easily testing in shell scripts whether some command | |
9863 | 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX' | |
9864 | returns with exit code 0 iff no command of the given name is available. | |
9865 | 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases, | |
9866 | the output goes to stdout and nothing is printed to stderr. | |
9867 | Additional arguments are always ignored. | |
9868 | ||
9869 | Since for each cipher there is a command of the same name, | |
9870 | the 'no-cipher' compilation switches can be tested this way. | |
9871 | ||
9872 | ('openssl no-XXX' is not able to detect pseudo-commands such | |
9873 | as 'quit', 'list-XXX-commands', or 'no-XXX' itself.) | |
9874 | [Bodo Moeller] | |
9875 | ||
9876 | *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration. | |
9877 | [Bodo Moeller] | |
9878 | ||
9879 | *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE | |
9880 | is set; it will be thrown away anyway because each handshake creates | |
9881 | its own key. | |
9882 | ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition | |
9883 | to parameters -- in previous versions (since OpenSSL 0.9.3) the | |
9884 | 'default key' from SSL_CTX_set_tmp_dh would always be lost, meaning | |
9885 | you effectively got SSL_OP_SINGLE_DH_USE when using this macro. | |
9886 | [Bodo Moeller] | |
9887 | ||
9888 | *) New s_client option -ign_eof: EOF at stdin is ignored, and | |
9889 | 'Q' and 'R' lose their special meanings (quit/renegotiate). | |
9890 | This is part of what -quiet does; unlike -quiet, -ign_eof | |
9891 | does not suppress any output. | |
9892 | [Richard Levitte] | |
9893 | ||
9894 | *) Add compatibility options to the purpose and trust code. The | |
9895 | purpose X509_PURPOSE_ANY is "any purpose" which automatically | |
9896 | accepts a certificate or CA, this was the previous behaviour, | |
9897 | with all the associated security issues. | |
9898 | ||
9899 | X509_TRUST_COMPAT is the old trust behaviour: only and | |
9900 | automatically trust self signed roots in certificate store. A | |
9901 | new trust setting X509_TRUST_DEFAULT is used to specify that | |
9902 | a purpose has no associated trust setting and it should instead | |
9903 | use the value in the default purpose. | |
9904 | [Steve Henson] | |
9905 | ||
9906 | *) Fix the PKCS#8 DSA private key code so it decodes keys again | |
9907 | and fix a memory leak. | |
9908 | [Steve Henson] | |
9909 | ||
9910 | *) In util/mkerr.pl (which implements 'make errors'), preserve | |
9911 | reason strings from the previous version of the .c file, as | |
9912 | the default to have only downcase letters (and digits) in | |
9913 | automatically generated reasons codes is not always appropriate. | |
9914 | [Bodo Moeller] | |
9915 | ||
9916 | *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table | |
9917 | using strerror. Previously, ERR_reason_error_string() returned | |
9918 | library names as reason strings for SYSerr; but SYSerr is a special | |
9919 | case where small numbers are errno values, not library numbers. | |
9920 | [Bodo Moeller] | |
9921 | ||
9922 | *) Add '-dsaparam' option to 'openssl dhparam' application. This | |
9923 | converts DSA parameters into DH parameters. (When creating parameters, | |
9924 | DSA_generate_parameters is used.) | |
9925 | [Bodo Moeller] | |
9926 | ||
9927 | *) Include 'length' (recommended exponent length) in C code generated | |
9928 | by 'openssl dhparam -C'. | |
9929 | [Bodo Moeller] | |
9930 | ||
9931 | *) The second argument to set_label in perlasm was already being used | |
9932 | so couldn't be used as a "file scope" flag. Moved to third argument | |
9933 | which was free. | |
9934 | [Steve Henson] | |
9935 | ||
9936 | *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes | |
9937 | instead of RAND_bytes for encryption IVs and salts. | |
9938 | [Bodo Moeller] | |
9939 | ||
9940 | *) Include RAND_status() into RAND_METHOD instead of implementing | |
9941 | it only for md_rand.c Otherwise replacing the PRNG by calling | |
9942 | RAND_set_rand_method would be impossible. | |
9943 | [Bodo Moeller] | |
9944 | ||
9945 | *) Don't let DSA_generate_key() enter an infinite loop if the random | |
9946 | number generation fails. | |
9947 | [Bodo Moeller] | |
9948 | ||
9949 | *) New 'rand' application for creating pseudo-random output. | |
9950 | [Bodo Moeller] | |
9951 | ||
9952 | *) Added configuration support for Linux/IA64 | |
9953 | [Rolf Haberrecker <rolf@suse.de>] | |
9954 | ||
9955 | *) Assembler module support for Mingw32. | |
9956 | [Ulf Möller] | |
9957 | ||
9958 | *) Shared library support for HPUX (in shlib/). | |
9959 | [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous] | |
9960 | ||
9961 | *) Shared library support for Solaris gcc. | |
9962 | [Lutz Behnke <behnke@trustcenter.de>] | |
9963 | ||
9964 | Changes between 0.9.4 and 0.9.5 [28 Feb 2000] | |
9965 | ||
9966 | *) PKCS7_encrypt() was adding text MIME headers twice because they | |
9967 | were added manually and by SMIME_crlf_copy(). | |
9968 | [Steve Henson] | |
9969 | ||
9970 | *) In bntest.c don't call BN_rand with zero bits argument. | |
9971 | [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>] | |
9972 | ||
9973 | *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n] | |
9974 | case was implemented. This caused BN_div_recp() to fail occasionally. | |
9975 | [Ulf Möller] | |
9976 | ||
9977 | *) Add an optional second argument to the set_label() in the perl | |
9978 | assembly language builder. If this argument exists and is set | |
9979 | to 1 it signals that the assembler should use a symbol whose | |
9980 | scope is the entire file, not just the current function. This | |
9981 | is needed with MASM which uses the format label:: for this scope. | |
9982 | [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>] | |
9983 | ||
9984 | *) Change the ASN1 types so they are typedefs by default. Before | |
9985 | almost all types were #define'd to ASN1_STRING which was causing | |
9986 | STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING) | |
9987 | for example. | |
9988 | [Steve Henson] | |
9989 | ||
9990 | *) Change names of new functions to the new get1/get0 naming | |
9991 | convention: After 'get1', the caller owns a reference count | |
9992 | and has to call ..._free; 'get0' returns a pointer to some | |
9993 | data structure without incrementing reference counters. | |
9994 | (Some of the existing 'get' functions increment a reference | |
9995 | counter, some don't.) | |
9996 | Similarly, 'set1' and 'add1' functions increase reference | |
9997 | counters or duplicate objects. | |
9998 | [Steve Henson] | |
9999 | ||
10000 | *) Allow for the possibility of temp RSA key generation failure: | |
10001 | the code used to assume it always worked and crashed on failure. | |
10002 | [Steve Henson] | |
10003 | ||
10004 | *) Fix potential buffer overrun problem in BIO_printf(). | |
10005 | [Ulf Möller, using public domain code by Patrick Powell; problem | |
10006 | pointed out by David Sacerdote <das33@cornell.edu>] | |
10007 | ||
10008 | *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions | |
10009 | RAND_egd() and RAND_status(). In the command line application, | |
10010 | the EGD socket can be specified like a seed file using RANDFILE | |
10011 | or -rand. | |
10012 | [Ulf Möller] | |
10013 | ||
10014 | *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures. | |
10015 | Some CAs (e.g. Verisign) distribute certificates in this form. | |
10016 | [Steve Henson] | |
10017 | ||
10018 | *) Remove the SSL_ALLOW_ADH compile option and set the default cipher | |
10019 | list to exclude them. This means that no special compilation option | |
10020 | is needed to use anonymous DH: it just needs to be included in the | |
10021 | cipher list. | |
10022 | [Steve Henson] | |
10023 | ||
10024 | *) Change the EVP_MD_CTX_type macro so its meaning consistent with | |
10025 | EVP_MD_type. The old functionality is available in a new macro called | |
10026 | EVP_MD_md(). Change code that uses it and update docs. | |
10027 | [Steve Henson] | |
10028 | ||
10029 | *) ..._ctrl functions now have corresponding ..._callback_ctrl functions | |
10030 | where the 'void *' argument is replaced by a function pointer argument. | |
10031 | Previously 'void *' was abused to point to functions, which works on | |
10032 | many platforms, but is not correct. As these functions are usually | |
10033 | called by macros defined in OpenSSL header files, most source code | |
10034 | should work without changes. | |
10035 | [Richard Levitte] | |
10036 | ||
10037 | *) <openssl/opensslconf.h> (which is created by Configure) now contains | |
10038 | sections with information on -D... compiler switches used for | |
10039 | compiling the library so that applications can see them. To enable | |
10040 | one of these sections, a pre-processor symbol OPENSSL_..._DEFINES | |
10041 | must be defined. E.g., | |
10042 | #define OPENSSL_ALGORITHM_DEFINES | |
10043 | #include <openssl/opensslconf.h> | |
10044 | defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc. | |
10045 | [Richard Levitte, Ulf and Bodo Möller] | |
10046 | ||
10047 | *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS | |
10048 | record layer. | |
10049 | [Bodo Moeller] | |
10050 | ||
10051 | *) Change the 'other' type in certificate aux info to a STACK_OF | |
10052 | X509_ALGOR. Although not an AlgorithmIdentifier as such it has | |
10053 | the required ASN1 format: arbitrary types determined by an OID. | |
10054 | [Steve Henson] | |
10055 | ||
10056 | *) Add some PEM_write_X509_REQ_NEW() functions and a command line | |
10057 | argument to 'req'. This is not because the function is newer or | |
10058 | better than others it just uses the work 'NEW' in the certificate | |
10059 | request header lines. Some software needs this. | |
10060 | [Steve Henson] | |
10061 | ||
10062 | *) Reorganise password command line arguments: now passwords can be | |
10063 | obtained from various sources. Delete the PEM_cb function and make | |
10064 | it the default behaviour: i.e. if the callback is NULL and the | |
10065 | usrdata argument is not NULL interpret it as a null terminated pass | |
10066 | phrase. If usrdata and the callback are NULL then the pass phrase | |
10067 | is prompted for as usual. | |
10068 | [Steve Henson] | |
10069 | ||
10070 | *) Add support for the Compaq Atalla crypto accelerator. If it is installed, | |
10071 | the support is automatically enabled. The resulting binaries will | |
10072 | autodetect the card and use it if present. | |
10073 | [Ben Laurie and Compaq Inc.] | |
10074 | ||
10075 | *) Work around for Netscape hang bug. This sends certificate request | |
10076 | and server done in one record. Since this is perfectly legal in the | |
10077 | SSL/TLS protocol it isn't a "bug" option and is on by default. See | |
10078 | the bugs/SSLv3 entry for more info. | |
10079 | [Steve Henson] | |
10080 | ||
10081 | *) HP-UX tune-up: new unified configs, HP C compiler bug workaround. | |
10082 | [Andy Polyakov] | |
10083 | ||
10084 | *) Add -rand argument to smime and pkcs12 applications and read/write | |
10085 | of seed file. | |
10086 | [Steve Henson] | |
10087 | ||
10088 | *) New 'passwd' tool for crypt(3) and apr1 password hashes. | |
10089 | [Bodo Moeller] | |
10090 | ||
10091 | *) Add command line password options to the remaining applications. | |
10092 | [Steve Henson] | |
10093 | ||
10094 | *) Bug fix for BN_div_recp() for numerators with an even number of | |
10095 | bits. | |
10096 | [Ulf Möller] | |
10097 | ||
10098 | *) More tests in bntest.c, and changed test_bn output. | |
10099 | [Ulf Möller] | |
10100 | ||
10101 | *) ./config recognizes MacOS X now. | |
10102 | [Andy Polyakov] | |
10103 | ||
10104 | *) Bug fix for BN_div() when the first words of num and divisor are | |
10105 | equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0). | |
10106 | [Ulf Möller] | |
10107 | ||
10108 | *) Add support for various broken PKCS#8 formats, and command line | |
10109 | options to produce them. | |
10110 | [Steve Henson] | |
10111 | ||
10112 | *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to | |
10113 | get temporary BIGNUMs from a BN_CTX. | |
10114 | [Ulf Möller] | |
10115 | ||
10116 | *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont() | |
10117 | for p == 0. | |
10118 | [Ulf Möller] | |
10119 | ||
10120 | *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and | |
10121 | include a #define from the old name to the new. The original intent | |
10122 | was that statically linked binaries could for example just call | |
10123 | SSLeay_add_all_ciphers() to just add ciphers to the table and not | |
10124 | link with digests. This never worked because SSLeay_add_all_digests() | |
10125 | and SSLeay_add_all_ciphers() were in the same source file so calling | |
10126 | one would link with the other. They are now in separate source files. | |
10127 | [Steve Henson] | |
10128 | ||
10129 | *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'. | |
10130 | [Steve Henson] | |
10131 | ||
10132 | *) Use a less unusual form of the Miller-Rabin primality test (it used | |
10133 | a binary algorithm for exponentiation integrated into the Miller-Rabin | |
10134 | loop, our standard modexp algorithms are faster). | |
10135 | [Bodo Moeller] | |
10136 | ||
10137 | *) Support for the EBCDIC character set completed. | |
10138 | [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>] | |
10139 | ||
10140 | *) Source code cleanups: use const where appropriate, eliminate casts, | |
10141 | use void * instead of char * in lhash. | |
10142 | [Ulf Möller] | |
10143 | ||
10144 | *) Bugfix: ssl3_send_server_key_exchange was not restartable | |
10145 | (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of | |
10146 | this the server could overwrite ephemeral keys that the client | |
10147 | has already seen). | |
10148 | [Bodo Moeller] | |
10149 | ||
10150 | *) Turn DSA_is_prime into a macro that calls BN_is_prime, | |
10151 | using 50 iterations of the Rabin-Miller test. | |
10152 | ||
10153 | DSA_generate_parameters now uses BN_is_prime_fasttest (with 50 | |
10154 | iterations of the Rabin-Miller test as required by the appendix | |
10155 | to FIPS PUB 186[-1]) instead of DSA_is_prime. | |
10156 | As BN_is_prime_fasttest includes trial division, DSA parameter | |
10157 | generation becomes much faster. | |
10158 | ||
10159 | This implies a change for the callback functions in DSA_is_prime | |
10160 | and DSA_generate_parameters: The callback function is called once | |
10161 | for each positive witness in the Rabin-Miller test, not just | |
10162 | occasionally in the inner loop; and the parameters to the | |
10163 | callback function now provide an iteration count for the outer | |
10164 | loop rather than for the current invocation of the inner loop. | |
10165 | DSA_generate_parameters additionally can call the callback | |
10166 | function with an 'iteration count' of -1, meaning that a | |
10167 | candidate has passed the trial division test (when q is generated | |
10168 | from an application-provided seed, trial division is skipped). | |
10169 | [Bodo Moeller] | |
10170 | ||
10171 | *) New function BN_is_prime_fasttest that optionally does trial | |
10172 | division before starting the Rabin-Miller test and has | |
10173 | an additional BN_CTX * argument (whereas BN_is_prime always | |
10174 | has to allocate at least one BN_CTX). | |
10175 | 'callback(1, -1, cb_arg)' is called when a number has passed the | |
10176 | trial division stage. | |
10177 | [Bodo Moeller] | |
10178 | ||
10179 | *) Fix for bug in CRL encoding. The validity dates weren't being handled | |
10180 | as ASN1_TIME. | |
10181 | [Steve Henson] | |
10182 | ||
10183 | *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file. | |
10184 | [Steve Henson] | |
10185 | ||
10186 | *) New function BN_pseudo_rand(). | |
10187 | [Ulf Möller] | |
10188 | ||
10189 | *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable) | |
10190 | bignum version of BN_from_montgomery() with the working code from | |
10191 | SSLeay 0.9.0 (the word based version is faster anyway), and clean up | |
10192 | the comments. | |
10193 | [Ulf Möller] | |
10194 | ||
10195 | *) Avoid a race condition in s2_clnt.c (function get_server_hello) that | |
10196 | made it impossible to use the same SSL_SESSION data structure in | |
10197 | SSL2 clients in multiple threads. | |
10198 | [Bodo Moeller] | |
10199 | ||
10200 | *) The return value of RAND_load_file() no longer counts bytes obtained | |
10201 | by stat(). RAND_load_file(..., -1) is new and uses the complete file | |
10202 | to seed the PRNG (previously an explicit byte count was required). | |
10203 | [Ulf Möller, Bodo Möller] | |
10204 | ||
10205 | *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes | |
10206 | used (char *) instead of (void *) and had casts all over the place. | |
10207 | [Steve Henson] | |
10208 | ||
10209 | *) Make BN_generate_prime() return NULL on error if ret!=NULL. | |
10210 | [Ulf Möller] | |
10211 | ||
10212 | *) Retain source code compatibility for BN_prime_checks macro: | |
10213 | BN_is_prime(..., BN_prime_checks, ...) now uses | |
10214 | BN_prime_checks_for_size to determine the appropriate number of | |
10215 | Rabin-Miller iterations. | |
10216 | [Ulf Möller] | |
10217 | ||
10218 | *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to | |
10219 | DH_CHECK_P_NOT_SAFE_PRIME. | |
10220 | (Check if this is true? OpenPGP calls them "strong".) | |
10221 | [Ulf Möller] | |
10222 | ||
10223 | *) Merge the functionality of "dh" and "gendh" programs into a new program | |
10224 | "dhparam". The old programs are retained for now but will handle DH keys | |
10225 | (instead of parameters) in future. | |
10226 | [Steve Henson] | |
10227 | ||
10228 | *) Make the ciphers, s_server and s_client programs check the return values | |
10229 | when a new cipher list is set. | |
10230 | [Steve Henson] | |
10231 | ||
10232 | *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit | |
10233 | ciphers. Before when the 56bit ciphers were enabled the sorting was | |
10234 | wrong. | |
10235 | ||
10236 | The syntax for the cipher sorting has been extended to support sorting by | |
10237 | cipher-strength (using the strength_bits hard coded in the tables). | |
10238 | The new command is "@STRENGTH" (see also doc/apps/ciphers.pod). | |
10239 | ||
10240 | Fix a bug in the cipher-command parser: when supplying a cipher command | |
10241 | string with an "undefined" symbol (neither command nor alphanumeric | |
10242 | [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now | |
10243 | an error is flagged. | |
10244 | ||
10245 | Due to the strength-sorting extension, the code of the | |
10246 | ssl_create_cipher_list() function was completely rearranged. I hope that | |
10247 | the readability was also increased :-) | |
10248 | [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>] | |
10249 | ||
10250 | *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1 | |
10251 | for the first serial number and places 2 in the serial number file. This | |
10252 | avoids problems when the root CA is created with serial number zero and | |
10253 | the first user certificate has the same issuer name and serial number | |
10254 | as the root CA. | |
10255 | [Steve Henson] | |
10256 | ||
10257 | *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses | |
10258 | the new code. Add documentation for this stuff. | |
10259 | [Steve Henson] | |
10260 | ||
10261 | *) Changes to X509_ATTRIBUTE utilities. These have been renamed from | |
10262 | X509_*() to X509at_*() on the grounds that they don't handle X509 | |
10263 | structures and behave in an analogous way to the X509v3 functions: | |
10264 | they shouldn't be called directly but wrapper functions should be used | |
10265 | instead. | |
10266 | ||
10267 | So we also now have some wrapper functions that call the X509at functions | |
10268 | when passed certificate requests. (TO DO: similar things can be done with | |
10269 | PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other | |
10270 | things. Some of these need some d2i or i2d and print functionality | |
10271 | because they handle more complex structures.) | |
10272 | [Steve Henson] | |
10273 | ||
10274 | *) Add missing #ifndefs that caused missing symbols when building libssl | |
10275 | as a shared library without RSA. Use #ifndef NO_SSL2 instead of | |
10276 | NO_RSA in ssl/s2*.c. | |
10277 | [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller] | |
10278 | ||
10279 | *) Precautions against using the PRNG uninitialized: RAND_bytes() now | |
10280 | has a return value which indicates the quality of the random data | |
10281 | (1 = ok, 0 = not seeded). Also an error is recorded on the thread's | |
10282 | error queue. New function RAND_pseudo_bytes() generates output that is | |
10283 | guaranteed to be unique but not unpredictable. RAND_add is like | |
10284 | RAND_seed, but takes an extra argument for an entropy estimate | |
10285 | (RAND_seed always assumes full entropy). | |
10286 | [Ulf Möller] | |
10287 | ||
10288 | *) Do more iterations of Rabin-Miller probable prime test (specifically, | |
10289 | 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes | |
10290 | instead of only 2 for all lengths; see BN_prime_checks_for_size definition | |
10291 | in crypto/bn/bn_prime.c for the complete table). This guarantees a | |
10292 | false-positive rate of at most 2^-80 for random input. | |
10293 | [Bodo Moeller] | |
10294 | ||
10295 | *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs. | |
10296 | [Bodo Moeller] | |
10297 | ||
10298 | *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain | |
10299 | in the 0.9.5 release), this returns the chain | |
10300 | from an X509_CTX structure with a dup of the stack and all | |
10301 | the X509 reference counts upped: so the stack will exist | |
10302 | after X509_CTX_cleanup() has been called. Modify pkcs12.c | |
10303 | to use this. | |
10304 | ||
10305 | Also make SSL_SESSION_print() print out the verify return | |
10306 | code. | |
10307 | [Steve Henson] | |
10308 | ||
10309 | *) Add manpage for the pkcs12 command. Also change the default | |
10310 | behaviour so MAC iteration counts are used unless the new | |
10311 | -nomaciter option is used. This improves file security and | |
10312 | only older versions of MSIE (4.0 for example) need it. | |
10313 | [Steve Henson] | |
10314 | ||
10315 | *) Honor the no-xxx Configure options when creating .DEF files. | |
10316 | [Ulf Möller] | |
10317 | ||
10318 | *) Add PKCS#10 attributes to field table: challengePassword, | |
10319 | unstructuredName and unstructuredAddress. These are taken from | |
10320 | draft PKCS#9 v2.0 but are compatible with v1.2 provided no | |
10321 | international characters are used. | |
10322 | ||
10323 | More changes to X509_ATTRIBUTE code: allow the setting of types | |
10324 | based on strings. Remove the 'loc' parameter when adding | |
10325 | attributes because these will be a SET OF encoding which is sorted | |
10326 | in ASN1 order. | |
10327 | [Steve Henson] | |
10328 | ||
10329 | *) Initial changes to the 'req' utility to allow request generation | |
10330 | automation. This will allow an application to just generate a template | |
10331 | file containing all the field values and have req construct the | |
10332 | request. | |
10333 | ||
10334 | Initial support for X509_ATTRIBUTE handling. Stacks of these are | |
10335 | used all over the place including certificate requests and PKCS#7 | |
10336 | structures. They are currently handled manually where necessary with | |
10337 | some primitive wrappers for PKCS#7. The new functions behave in a | |
10338 | manner analogous to the X509 extension functions: they allow | |
10339 | attributes to be looked up by NID and added. | |
10340 | ||
10341 | Later something similar to the X509V3 code would be desirable to | |
10342 | automatically handle the encoding, decoding and printing of the | |
10343 | more complex types. The string types like challengePassword can | |
10344 | be handled by the string table functions. | |
10345 | ||
10346 | Also modified the multi byte string table handling. Now there is | |
10347 | a 'global mask' which masks out certain types. The table itself | |
10348 | can use the flag STABLE_NO_MASK to ignore the mask setting: this | |
10349 | is useful when for example there is only one permissible type | |
10350 | (as in countryName) and using the mask might result in no valid | |
10351 | types at all. | |
10352 | [Steve Henson] | |
10353 | ||
10354 | *) Clean up 'Finished' handling, and add functions SSL_get_finished and | |
10355 | SSL_get_peer_finished to allow applications to obtain the latest | |
10356 | Finished messages sent to the peer or expected from the peer, | |
10357 | respectively. (SSL_get_peer_finished is usually the Finished message | |
10358 | actually received from the peer, otherwise the protocol will be aborted.) | |
10359 | ||
10360 | As the Finished message are message digests of the complete handshake | |
10361 | (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can | |
10362 | be used for external authentication procedures when the authentication | |
10363 | provided by SSL/TLS is not desired or is not enough. | |
10364 | [Bodo Moeller] | |
10365 | ||
10366 | *) Enhanced support for Alpha Linux is added. Now ./config checks if | |
10367 | the host supports BWX extension and if Compaq C is present on the | |
10368 | $PATH. Just exploiting of the BWX extension results in 20-30% | |
10369 | performance kick for some algorithms, e.g. DES and RC4 to mention | |
10370 | a couple. Compaq C in turn generates ~20% faster code for MD5 and | |
10371 | SHA1. | |
10372 | [Andy Polyakov] | |
10373 | ||
10374 | *) Add support for MS "fast SGC". This is arguably a violation of the | |
10375 | SSL3/TLS protocol. Netscape SGC does two handshakes: the first with | |
10376 | weak crypto and after checking the certificate is SGC a second one | |
10377 | with strong crypto. MS SGC stops the first handshake after receiving | |
10378 | the server certificate message and sends a second client hello. Since | |
10379 | a server will typically do all the time consuming operations before | |
10380 | expecting any further messages from the client (server key exchange | |
10381 | is the most expensive) there is little difference between the two. | |
10382 | ||
10383 | To get OpenSSL to support MS SGC we have to permit a second client | |
10384 | hello message after we have sent server done. In addition we have to | |
10385 | reset the MAC if we do get this second client hello. | |
10386 | [Steve Henson] | |
10387 | ||
10388 | *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide | |
10389 | if a DER encoded private key is RSA or DSA traditional format. Changed | |
10390 | d2i_PrivateKey_bio() to use it. This is only needed for the "traditional" | |
10391 | format DER encoded private key. Newer code should use PKCS#8 format which | |
10392 | has the key type encoded in the ASN1 structure. Added DER private key | |
10393 | support to pkcs8 application. | |
10394 | [Steve Henson] | |
10395 | ||
10396 | *) SSL 3/TLS 1 servers now don't request certificates when an anonymous | |
10397 | ciphersuites has been selected (as required by the SSL 3/TLS 1 | |
10398 | specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT | |
10399 | is set, we interpret this as a request to violate the specification | |
10400 | (the worst that can happen is a handshake failure, and 'correct' | |
10401 | behaviour would result in a handshake failure anyway). | |
10402 | [Bodo Moeller] | |
10403 | ||
10404 | *) In SSL_CTX_add_session, take into account that there might be multiple | |
10405 | SSL_SESSION structures with the same session ID (e.g. when two threads | |
10406 | concurrently obtain them from an external cache). | |
10407 | The internal cache can handle only one SSL_SESSION with a given ID, | |
10408 | so if there's a conflict, we now throw out the old one to achieve | |
10409 | consistency. | |
10410 | [Bodo Moeller] | |
10411 | ||
10412 | *) Add OIDs for idea and blowfish in CBC mode. This will allow both | |
10413 | to be used in PKCS#5 v2.0 and S/MIME. Also add checking to | |
10414 | some routines that use cipher OIDs: some ciphers do not have OIDs | |
10415 | defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for | |
10416 | example. | |
10417 | [Steve Henson] | |
10418 | ||
10419 | *) Simplify the trust setting structure and code. Now we just have | |
10420 | two sequences of OIDs for trusted and rejected settings. These will | |
10421 | typically have values the same as the extended key usage extension | |
10422 | and any application specific purposes. | |
10423 | ||
10424 | The trust checking code now has a default behaviour: it will just | |
10425 | check for an object with the same NID as the passed id. Functions can | |
10426 | be provided to override either the default behaviour or the behaviour | |
10427 | for a given id. SSL client, server and email already have functions | |
10428 | in place for compatibility: they check the NID and also return "trusted" | |
10429 | if the certificate is self signed. | |
10430 | [Steve Henson] | |
10431 | ||
10432 | *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the | |
10433 | traditional format into an EVP_PKEY structure. | |
10434 | [Steve Henson] | |
10435 | ||
10436 | *) Add a password callback function PEM_cb() which either prompts for | |
10437 | a password if usr_data is NULL or otherwise assumes it is a null | |
10438 | terminated password. Allow passwords to be passed on command line | |
10439 | environment or config files in a few more utilities. | |
10440 | [Steve Henson] | |
10441 | ||
10442 | *) Add a bunch of DER and PEM functions to handle PKCS#8 format private | |
10443 | keys. Add some short names for PKCS#8 PBE algorithms and allow them | |
10444 | to be specified on the command line for the pkcs8 and pkcs12 utilities. | |
10445 | Update documentation. | |
10446 | [Steve Henson] | |
10447 | ||
10448 | *) Support for ASN1 "NULL" type. This could be handled before by using | |
10449 | ASN1_TYPE but there wasn't any function that would try to read a NULL | |
10450 | and produce an error if it couldn't. For compatibility we also have | |
10451 | ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and | |
10452 | don't allocate anything because they don't need to. | |
10453 | [Steve Henson] | |
10454 | ||
10455 | *) Initial support for MacOS is now provided. Examine INSTALL.MacOS | |
10456 | for details. | |
10457 | [Andy Polyakov, Roy Woods <roy@centicsystems.ca>] | |
10458 | ||
10459 | *) Rebuild of the memory allocation routines used by OpenSSL code and | |
10460 | possibly others as well. The purpose is to make an interface that | |
10461 | provide hooks so anyone can build a separate set of allocation and | |
10462 | deallocation routines to be used by OpenSSL, for example memory | |
10463 | pool implementations, or something else, which was previously hard | |
10464 | since Malloc(), Realloc() and Free() were defined as macros having | |
10465 | the values malloc, realloc and free, respectively (except for Win32 | |
10466 | compilations). The same is provided for memory debugging code. | |
10467 | OpenSSL already comes with functionality to find memory leaks, but | |
10468 | this gives people a chance to debug other memory problems. | |
10469 | ||
10470 | With these changes, a new set of functions and macros have appeared: | |
10471 | ||
10472 | CRYPTO_set_mem_debug_functions() [F] | |
10473 | CRYPTO_get_mem_debug_functions() [F] | |
10474 | CRYPTO_dbg_set_options() [F] | |
10475 | CRYPTO_dbg_get_options() [F] | |
10476 | CRYPTO_malloc_debug_init() [M] | |
10477 | ||
10478 | The memory debug functions are NULL by default, unless the library | |
10479 | is compiled with CRYPTO_MDEBUG or friends is defined. If someone | |
10480 | wants to debug memory anyway, CRYPTO_malloc_debug_init() (which | |
10481 | gives the standard debugging functions that come with OpenSSL) or | |
10482 | CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions | |
10483 | provided by the library user) must be used. When the standard | |
10484 | debugging functions are used, CRYPTO_dbg_set_options can be used to | |
10485 | request additional information: | |
10486 | CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting | |
10487 | the CRYPTO_MDEBUG_xxx macro when compiling the library. | |
10488 | ||
10489 | Also, things like CRYPTO_set_mem_functions will always give the | |
10490 | expected result (the new set of functions is used for allocation | |
10491 | and deallocation) at all times, regardless of platform and compiler | |
10492 | options. | |
10493 | ||
10494 | To finish it up, some functions that were never use in any other | |
10495 | way than through macros have a new API and new semantic: | |
10496 | ||
10497 | CRYPTO_dbg_malloc() | |
10498 | CRYPTO_dbg_realloc() | |
10499 | CRYPTO_dbg_free() | |
10500 | ||
10501 | All macros of value have retained their old syntax. | |
10502 | [Richard Levitte and Bodo Moeller] | |
10503 | ||
10504 | *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the | |
10505 | ordering of SMIMECapabilities wasn't in "strength order" and there | |
10506 | was a missing NULL in the AlgorithmIdentifier for the SHA1 signature | |
10507 | algorithm. | |
10508 | [Steve Henson] | |
10509 | ||
10510 | *) Some ASN1 types with illegal zero length encoding (INTEGER, | |
10511 | ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines. | |
10512 | [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson] | |
10513 | ||
10514 | *) Merge in my S/MIME library for OpenSSL. This provides a simple | |
10515 | S/MIME API on top of the PKCS#7 code, a MIME parser (with enough | |
10516 | functionality to handle multipart/signed properly) and a utility | |
10517 | called 'smime' to call all this stuff. This is based on code I | |
10518 | originally wrote for Celo who have kindly allowed it to be | |
10519 | included in OpenSSL. | |
10520 | [Steve Henson] | |
10521 | ||
10522 | *) Add variants des_set_key_checked and des_set_key_unchecked of | |
10523 | des_set_key (aka des_key_sched). Global variable des_check_key | |
10524 | decides which of these is called by des_set_key; this way | |
10525 | des_check_key behaves as it always did, but applications and | |
10526 | the library itself, which was buggy for des_check_key == 1, | |
10527 | have a cleaner way to pick the version they need. | |
10528 | [Bodo Moeller] | |
10529 | ||
10530 | *) New function PKCS12_newpass() which changes the password of a | |
10531 | PKCS12 structure. | |
10532 | [Steve Henson] | |
10533 | ||
10534 | *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and | |
10535 | dynamic mix. In both cases the ids can be used as an index into the | |
10536 | table. Also modified the X509_TRUST_add() and X509_PURPOSE_add() | |
10537 | functions so they accept a list of the field values and the | |
10538 | application doesn't need to directly manipulate the X509_TRUST | |
10539 | structure. | |
10540 | [Steve Henson] | |
10541 | ||
10542 | *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't | |
10543 | need initialising. | |
10544 | [Steve Henson] | |
10545 | ||
10546 | *) Modify the way the V3 extension code looks up extensions. This now | |
10547 | works in a similar way to the object code: we have some "standard" | |
10548 | extensions in a static table which is searched with OBJ_bsearch() | |
10549 | and the application can add dynamic ones if needed. The file | |
10550 | crypto/x509v3/ext_dat.h now has the info: this file needs to be | |
10551 | updated whenever a new extension is added to the core code and kept | |
10552 | in ext_nid order. There is a simple program 'tabtest.c' which checks | |
10553 | this. New extensions are not added too often so this file can readily | |
10554 | be maintained manually. | |
10555 | ||
10556 | There are two big advantages in doing things this way. The extensions | |
10557 | can be looked up immediately and no longer need to be "added" using | |
10558 | X509V3_add_standard_extensions(): this function now does nothing. | |
10559 | [Side note: I get *lots* of email saying the extension code doesn't | |
10560 | work because people forget to call this function] | |
10561 | Also no dynamic allocation is done unless new extensions are added: | |
10562 | so if we don't add custom extensions there is no need to call | |
10563 | X509V3_EXT_cleanup(). | |
10564 | [Steve Henson] | |
10565 | ||
10566 | *) Modify enc utility's salting as follows: make salting the default. Add a | |
10567 | magic header, so unsalted files fail gracefully instead of just decrypting | |
10568 | to garbage. This is because not salting is a big security hole, so people | |
10569 | should be discouraged from doing it. | |
10570 | [Ben Laurie] | |
10571 | ||
10572 | *) Fixes and enhancements to the 'x509' utility. It allowed a message | |
10573 | digest to be passed on the command line but it only used this | |
10574 | parameter when signing a certificate. Modified so all relevant | |
10575 | operations are affected by the digest parameter including the | |
10576 | -fingerprint and -x509toreq options. Also -x509toreq choked if a | |
10577 | DSA key was used because it didn't fix the digest. | |
10578 | [Steve Henson] | |
10579 | ||
10580 | *) Initial certificate chain verify code. Currently tests the untrusted | |
10581 | certificates for consistency with the verify purpose (which is set | |
10582 | when the X509_STORE_CTX structure is set up) and checks the pathlength. | |
10583 | ||
10584 | There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour: | |
10585 | this is because it will reject chains with invalid extensions whereas | |
10586 | every previous version of OpenSSL and SSLeay made no checks at all. | |
10587 | ||
10588 | Trust code: checks the root CA for the relevant trust settings. Trust | |
10589 | settings have an initial value consistent with the verify purpose: e.g. | |
10590 | if the verify purpose is for SSL client use it expects the CA to be | |
10591 | trusted for SSL client use. However the default value can be changed to | |
10592 | permit custom trust settings: one example of this would be to only trust | |
10593 | certificates from a specific "secure" set of CAs. | |
10594 | ||
10595 | Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions | |
10596 | which should be used for version portability: especially since the | |
10597 | verify structure is likely to change more often now. | |
10598 | ||
10599 | SSL integration. Add purpose and trust to SSL_CTX and SSL and functions | |
10600 | to set them. If not set then assume SSL clients will verify SSL servers | |
10601 | and vice versa. | |
10602 | ||
10603 | Two new options to the verify program: -untrusted allows a set of | |
10604 | untrusted certificates to be passed in and -purpose which sets the | |
10605 | intended purpose of the certificate. If a purpose is set then the | |
10606 | new chain verify code is used to check extension consistency. | |
10607 | [Steve Henson] | |
10608 | ||
10609 | *) Support for the authority information access extension. | |
10610 | [Steve Henson] | |
10611 | ||
10612 | *) Modify RSA and DSA PEM read routines to transparently handle | |
10613 | PKCS#8 format private keys. New *_PUBKEY_* functions that handle | |
10614 | public keys in a format compatible with certificate | |
10615 | SubjectPublicKeyInfo structures. Unfortunately there were already | |
10616 | functions called *_PublicKey_* which used various odd formats so | |
10617 | these are retained for compatibility: however the DSA variants were | |
10618 | never in a public release so they have been deleted. Changed dsa/rsa | |
10619 | utilities to handle the new format: note no releases ever handled public | |
10620 | keys so we should be OK. | |
10621 | ||
10622 | The primary motivation for this change is to avoid the same fiasco | |
10623 | that dogs private keys: there are several incompatible private key | |
10624 | formats some of which are standard and some OpenSSL specific and | |
10625 | require various evil hacks to allow partial transparent handling and | |
10626 | even then it doesn't work with DER formats. Given the option anything | |
10627 | other than PKCS#8 should be dumped: but the other formats have to | |
10628 | stay in the name of compatibility. | |
10629 | ||
10630 | With public keys and the benefit of hindsight one standard format | |
10631 | is used which works with EVP_PKEY, RSA or DSA structures: though | |
10632 | it clearly returns an error if you try to read the wrong kind of key. | |
10633 | ||
10634 | Added a -pubkey option to the 'x509' utility to output the public key. | |
10635 | Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*() | |
10636 | (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add | |
10637 | EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*()) | |
10638 | that do the same as the EVP_PKEY_assign_*() except they up the | |
10639 | reference count of the added key (they don't "swallow" the | |
10640 | supplied key). | |
10641 | [Steve Henson] | |
10642 | ||
10643 | *) Fixes to crypto/x509/by_file.c the code to read in certificates and | |
10644 | CRLs would fail if the file contained no certificates or no CRLs: | |
10645 | added a new function to read in both types and return the number | |
10646 | read: this means that if none are read it will be an error. The | |
10647 | DER versions of the certificate and CRL reader would always fail | |
10648 | because it isn't possible to mix certificates and CRLs in DER format | |
10649 | without choking one or the other routine. Changed this to just read | |
10650 | a certificate: this is the best we can do. Also modified the code | |
10651 | in apps/verify.c to take notice of return codes: it was previously | |
10652 | attempting to read in certificates from NULL pointers and ignoring | |
10653 | any errors: this is one reason why the cert and CRL reader seemed | |
10654 | to work. It doesn't check return codes from the default certificate | |
10655 | routines: these may well fail if the certificates aren't installed. | |
10656 | [Steve Henson] | |
10657 | ||
10658 | *) Code to support otherName option in GeneralName. | |
10659 | [Steve Henson] | |
10660 | ||
10661 | *) First update to verify code. Change the verify utility | |
10662 | so it warns if it is passed a self signed certificate: | |
10663 | for consistency with the normal behaviour. X509_verify | |
10664 | has been modified to it will now verify a self signed | |
10665 | certificate if *exactly* the same certificate appears | |
10666 | in the store: it was previously impossible to trust a | |
10667 | single self signed certificate. This means that: | |
10668 | openssl verify ss.pem | |
10669 | now gives a warning about a self signed certificate but | |
10670 | openssl verify -CAfile ss.pem ss.pem | |
10671 | is OK. | |
10672 | [Steve Henson] | |
10673 | ||
10674 | *) For servers, store verify_result in SSL_SESSION data structure | |
10675 | (and add it to external session representation). | |
10676 | This is needed when client certificate verifications fails, | |
10677 | but an application-provided verification callback (set by | |
10678 | SSL_CTX_set_cert_verify_callback) allows accepting the session | |
10679 | anyway (i.e. leaves x509_store_ctx->error != X509_V_OK | |
10680 | but returns 1): When the session is reused, we have to set | |
10681 | ssl->verify_result to the appropriate error code to avoid | |
10682 | security holes. | |
10683 | [Bodo Moeller, problem pointed out by Lutz Jaenicke] | |
10684 | ||
10685 | *) Fix a bug in the new PKCS#7 code: it didn't consider the | |
10686 | case in PKCS7_dataInit() where the signed PKCS7 structure | |
10687 | didn't contain any existing data because it was being created. | |
10688 | [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson] | |
10689 | ||
10690 | *) Add a salt to the key derivation routines in enc.c. This | |
10691 | forms the first 8 bytes of the encrypted file. Also add a | |
10692 | -S option to allow a salt to be input on the command line. | |
10693 | [Steve Henson] | |
10694 | ||
10695 | *) New function X509_cmp(). Oddly enough there wasn't a function | |
10696 | to compare two certificates. We do this by working out the SHA1 | |
10697 | hash and comparing that. X509_cmp() will be needed by the trust | |
10698 | code. | |
10699 | [Steve Henson] | |
10700 | ||
10701 | *) SSL_get1_session() is like SSL_get_session(), but increments | |
10702 | the reference count in the SSL_SESSION returned. | |
10703 | [Geoff Thorpe <geoff@eu.c2.net>] | |
10704 | ||
10705 | *) Fix for 'req': it was adding a null to request attributes. | |
10706 | Also change the X509_LOOKUP and X509_INFO code to handle | |
10707 | certificate auxiliary information. | |
10708 | [Steve Henson] | |
10709 | ||
10710 | *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document | |
10711 | the 'enc' command. | |
10712 | [Steve Henson] | |
10713 | ||
10714 | *) Add the possibility to add extra information to the memory leak | |
10715 | detecting output, to form tracebacks, showing from where each | |
10716 | allocation was originated: CRYPTO_push_info("constant string") adds | |
10717 | the string plus current file name and line number to a per-thread | |
10718 | stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info() | |
10719 | is like calling CYRPTO_pop_info() until the stack is empty. | |
10720 | Also updated memory leak detection code to be multi-thread-safe. | |
10721 | [Richard Levitte] | |
10722 | ||
10723 | *) Add options -text and -noout to pkcs7 utility and delete the | |
10724 | encryption options which never did anything. Update docs. | |
10725 | [Steve Henson] | |
10726 | ||
10727 | *) Add options to some of the utilities to allow the pass phrase | |
10728 | to be included on either the command line (not recommended on | |
10729 | OSes like Unix) or read from the environment. Update the | |
10730 | manpages and fix a few bugs. | |
10731 | [Steve Henson] | |
10732 | ||
10733 | *) Add a few manpages for some of the openssl commands. | |
10734 | [Steve Henson] | |
10735 | ||
10736 | *) Fix the -revoke option in ca. It was freeing up memory twice, | |
10737 | leaking and not finding already revoked certificates. | |
10738 | [Steve Henson] | |
10739 | ||
10740 | *) Extensive changes to support certificate auxiliary information. | |
10741 | This involves the use of X509_CERT_AUX structure and X509_AUX | |
10742 | functions. An X509_AUX function such as PEM_read_X509_AUX() | |
10743 | can still read in a certificate file in the usual way but it | |
10744 | will also read in any additional "auxiliary information". By | |
10745 | doing things this way a fair degree of compatibility can be | |
10746 | retained: existing certificates can have this information added | |
10747 | using the new 'x509' options. | |
10748 | ||
10749 | Current auxiliary information includes an "alias" and some trust | |
10750 | settings. The trust settings will ultimately be used in enhanced | |
10751 | certificate chain verification routines: currently a certificate | |
10752 | can only be trusted if it is self signed and then it is trusted | |
10753 | for all purposes. | |
10754 | [Steve Henson] | |
10755 | ||
10756 | *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD). | |
10757 | The problem was that one of the replacement routines had not been working | |
10758 | since SSLeay releases. For now the offending routine has been replaced | |
10759 | with non-optimised assembler. Even so, this now gives around 95% | |
10760 | performance improvement for 1024 bit RSA signs. | |
10761 | [Mark Cox] | |
10762 | ||
10763 | *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2 | |
10764 | handling. Most clients have the effective key size in bits equal to | |
10765 | the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key. | |
10766 | A few however don't do this and instead use the size of the decrypted key | |
10767 | to determine the RC2 key length and the AlgorithmIdentifier to determine | |
10768 | the effective key length. In this case the effective key length can still | |
10769 | be 40 bits but the key length can be 168 bits for example. This is fixed | |
10770 | by manually forcing an RC2 key into the EVP_PKEY structure because the | |
10771 | EVP code can't currently handle unusual RC2 key sizes: it always assumes | |
10772 | the key length and effective key length are equal. | |
10773 | [Steve Henson] | |
10774 | ||
10775 | *) Add a bunch of functions that should simplify the creation of | |
10776 | X509_NAME structures. Now you should be able to do: | |
10777 | X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0); | |
10778 | and have it automatically work out the correct field type and fill in | |
10779 | the structures. The more adventurous can try: | |
10780 | X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0); | |
10781 | and it will (hopefully) work out the correct multibyte encoding. | |
10782 | [Steve Henson] | |
10783 | ||
10784 | *) Change the 'req' utility to use the new field handling and multibyte | |
10785 | copy routines. Before the DN field creation was handled in an ad hoc | |
10786 | way in req, ca, and x509 which was rather broken and didn't support | |
10787 | BMPStrings or UTF8Strings. Since some software doesn't implement | |
10788 | BMPStrings or UTF8Strings yet, they can be enabled using the config file | |
10789 | using the dirstring_type option. See the new comment in the default | |
10790 | openssl.cnf for more info. | |
10791 | [Steve Henson] | |
10792 | ||
10793 | *) Make crypto/rand/md_rand.c more robust: | |
10794 | - Assure unique random numbers after fork(). | |
10795 | - Make sure that concurrent threads access the global counter and | |
10796 | md serializably so that we never lose entropy in them | |
10797 | or use exactly the same state in multiple threads. | |
10798 | Access to the large state is not always serializable because | |
10799 | the additional locking could be a performance killer, and | |
10800 | md should be large enough anyway. | |
10801 | [Bodo Moeller] | |
10802 | ||
10803 | *) New file apps/app_rand.c with commonly needed functionality | |
10804 | for handling the random seed file. | |
10805 | ||
10806 | Use the random seed file in some applications that previously did not: | |
10807 | ca, | |
10808 | dsaparam -genkey (which also ignored its '-rand' option), | |
10809 | s_client, | |
10810 | s_server, | |
10811 | x509 (when signing). | |
10812 | Except on systems with /dev/urandom, it is crucial to have a random | |
10813 | seed file at least for key creation, DSA signing, and for DH exchanges; | |
10814 | for RSA signatures we could do without one. | |
10815 | ||
10816 | gendh and gendsa (unlike genrsa) used to read only the first byte | |
10817 | of each file listed in the '-rand' option. The function as previously | |
10818 | found in genrsa is now in app_rand.c and is used by all programs | |
10819 | that support '-rand'. | |
10820 | [Bodo Moeller] | |
10821 | ||
10822 | *) In RAND_write_file, use mode 0600 for creating files; | |
10823 | don't just chmod when it may be too late. | |
10824 | [Bodo Moeller] | |
10825 | ||
10826 | *) Report an error from X509_STORE_load_locations | |
10827 | when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed. | |
10828 | [Bill Perry] | |
10829 | ||
10830 | *) New function ASN1_mbstring_copy() this copies a string in either | |
10831 | ASCII, Unicode, Universal (4 bytes per character) or UTF8 format | |
10832 | into an ASN1_STRING type. A mask of permissible types is passed | |
10833 | and it chooses the "minimal" type to use or an error if not type | |
10834 | is suitable. | |
10835 | [Steve Henson] | |
10836 | ||
10837 | *) Add function equivalents to the various macros in asn1.h. The old | |
10838 | macros are retained with an M_ prefix. Code inside the library can | |
10839 | use the M_ macros. External code (including the openssl utility) | |
10840 | should *NOT* in order to be "shared library friendly". | |
10841 | [Steve Henson] | |
10842 | ||
10843 | *) Add various functions that can check a certificate's extensions | |
10844 | to see if it usable for various purposes such as SSL client, | |
10845 | server or S/MIME and CAs of these types. This is currently | |
10846 | VERY EXPERIMENTAL but will ultimately be used for certificate chain | |
10847 | verification. Also added a -purpose flag to x509 utility to | |
10848 | print out all the purposes. | |
10849 | [Steve Henson] | |
10850 | ||
10851 | *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated | |
10852 | functions. | |
10853 | [Steve Henson] | |
10854 | ||
10855 | *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search | |
10856 | for, obtain and decode and extension and obtain its critical flag. | |
10857 | This allows all the necessary extension code to be handled in a | |
10858 | single function call. | |
10859 | [Steve Henson] | |
10860 | ||
10861 | *) RC4 tune-up featuring 30-40% performance improvement on most RISC | |
10862 | platforms. See crypto/rc4/rc4_enc.c for further details. | |
10863 | [Andy Polyakov] | |
10864 | ||
10865 | *) New -noout option to asn1parse. This causes no output to be produced | |
10866 | its main use is when combined with -strparse and -out to extract data | |
10867 | from a file (which may not be in ASN.1 format). | |
10868 | [Steve Henson] | |
10869 | ||
10870 | *) Fix for pkcs12 program. It was hashing an invalid certificate pointer | |
10871 | when producing the local key id. | |
10872 | [Richard Levitte <levitte@stacken.kth.se>] | |
10873 | ||
10874 | *) New option -dhparam in s_server. This allows a DH parameter file to be | |
10875 | stated explicitly. If it is not stated then it tries the first server | |
10876 | certificate file. The previous behaviour hard coded the filename | |
10877 | "server.pem". | |
10878 | [Steve Henson] | |
10879 | ||
10880 | *) Add -pubin and -pubout options to the rsa and dsa commands. These allow | |
10881 | a public key to be input or output. For example: | |
10882 | openssl rsa -in key.pem -pubout -out pubkey.pem | |
10883 | Also added necessary DSA public key functions to handle this. | |
10884 | [Steve Henson] | |
10885 | ||
10886 | *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained | |
10887 | in the message. This was handled by allowing | |
10888 | X509_find_by_issuer_and_serial() to tolerate a NULL passed to it. | |
10889 | [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>] | |
10890 | ||
10891 | *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null | |
10892 | to the end of the strings whereas this didn't. This would cause problems | |
10893 | if strings read with d2i_ASN1_bytes() were later modified. | |
10894 | [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>] | |
10895 | ||
10896 | *) Fix for base64 decode bug. When a base64 bio reads only one line of | |
10897 | data and it contains EOF it will end up returning an error. This is | |
10898 | caused by input 46 bytes long. The cause is due to the way base64 | |
10899 | BIOs find the start of base64 encoded data. They do this by trying a | |
10900 | trial decode on each line until they find one that works. When they | |
10901 | do a flag is set and it starts again knowing it can pass all the | |
10902 | data directly through the decoder. Unfortunately it doesn't reset | |
10903 | the context it uses. This means that if EOF is reached an attempt | |
10904 | is made to pass two EOFs through the context and this causes the | |
10905 | resulting error. This can also cause other problems as well. As is | |
10906 | usual with these problems it takes *ages* to find and the fix is | |
10907 | trivial: move one line. | |
10908 | [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ] | |
10909 | ||
10910 | *) Ugly workaround to get s_client and s_server working under Windows. The | |
10911 | old code wouldn't work because it needed to select() on sockets and the | |
10912 | tty (for keypresses and to see if data could be written). Win32 only | |
10913 | supports select() on sockets so we select() with a 1s timeout on the | |
10914 | sockets and then see if any characters are waiting to be read, if none | |
10915 | are present then we retry, we also assume we can always write data to | |
10916 | the tty. This isn't nice because the code then blocks until we've | |
10917 | received a complete line of data and it is effectively polling the | |
10918 | keyboard at 1s intervals: however it's quite a bit better than not | |
10919 | working at all :-) A dedicated Windows application might handle this | |
10920 | with an event loop for example. | |
10921 | [Steve Henson] | |
10922 | ||
10923 | *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign | |
10924 | and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions | |
10925 | will be called when RSA_sign() and RSA_verify() are used. This is useful | |
10926 | if rsa_pub_dec() and rsa_priv_enc() equivalents are not available. | |
10927 | For this to work properly RSA_public_decrypt() and RSA_private_encrypt() | |
10928 | should *not* be used: RSA_sign() and RSA_verify() must be used instead. | |
10929 | This necessitated the support of an extra signature type NID_md5_sha1 | |
10930 | for SSL signatures and modifications to the SSL library to use it instead | |
10931 | of calling RSA_public_decrypt() and RSA_private_encrypt(). | |
10932 | [Steve Henson] | |
10933 | ||
10934 | *) Add new -verify -CAfile and -CApath options to the crl program, these | |
10935 | will lookup a CRL issuers certificate and verify the signature in a | |
10936 | similar way to the verify program. Tidy up the crl program so it | |
10937 | no longer accesses structures directly. Make the ASN1 CRL parsing a bit | |
10938 | less strict. It will now permit CRL extensions even if it is not | |
10939 | a V2 CRL: this will allow it to tolerate some broken CRLs. | |
10940 | [Steve Henson] | |
10941 | ||
10942 | *) Initialize all non-automatic variables each time one of the openssl | |
10943 | sub-programs is started (this is necessary as they may be started | |
10944 | multiple times from the "OpenSSL>" prompt). | |
10945 | [Lennart Bang, Bodo Moeller] | |
10946 | ||
10947 | *) Preliminary compilation option RSA_NULL which disables RSA crypto without | |
10948 | removing all other RSA functionality (this is what NO_RSA does). This | |
10949 | is so (for example) those in the US can disable those operations covered | |
10950 | by the RSA patent while allowing storage and parsing of RSA keys and RSA | |
10951 | key generation. | |
10952 | [Steve Henson] | |
10953 | ||
10954 | *) Non-copying interface to BIO pairs. | |
10955 | (still largely untested) | |
10956 | [Bodo Moeller] | |
10957 | ||
10958 | *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive | |
10959 | ASCII string. This was handled independently in various places before. | |
10960 | [Steve Henson] | |
10961 | ||
10962 | *) New functions UTF8_getc() and UTF8_putc() that parse and generate | |
10963 | UTF8 strings a character at a time. | |
10964 | [Steve Henson] | |
10965 | ||
10966 | *) Use client_version from client hello to select the protocol | |
10967 | (s23_srvr.c) and for RSA client key exchange verification | |
10968 | (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications. | |
10969 | [Bodo Moeller] | |
10970 | ||
10971 | *) Add various utility functions to handle SPKACs, these were previously | |
10972 | handled by poking round in the structure internals. Added new function | |
10973 | NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to | |
10974 | print, verify and generate SPKACs. Based on an original idea from | |
10975 | Massimiliano Pala <madwolf@comune.modena.it> but extensively modified. | |
10976 | [Steve Henson] | |
10977 | ||
10978 | *) RIPEMD160 is operational on all platforms and is back in 'make test'. | |
10979 | [Andy Polyakov] | |
10980 | ||
10981 | *) Allow the config file extension section to be overwritten on the | |
10982 | command line. Based on an original idea from Massimiliano Pala | |
10983 | <madwolf@comune.modena.it>. The new option is called -extensions | |
10984 | and can be applied to ca, req and x509. Also -reqexts to override | |
10985 | the request extensions in req and -crlexts to override the crl extensions | |
10986 | in ca. | |
10987 | [Steve Henson] | |
10988 | ||
10989 | *) Add new feature to the SPKAC handling in ca. Now you can include | |
10990 | the same field multiple times by preceding it by "XXXX." for example: | |
10991 | 1.OU="Unit name 1" | |
10992 | 2.OU="Unit name 2" | |
10993 | this is the same syntax as used in the req config file. | |
10994 | [Steve Henson] | |
10995 | ||
10996 | *) Allow certificate extensions to be added to certificate requests. These | |
10997 | are specified in a 'req_extensions' option of the req section of the | |
10998 | config file. They can be printed out with the -text option to req but | |
10999 | are otherwise ignored at present. | |
11000 | [Steve Henson] | |
11001 | ||
11002 | *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first | |
11003 | data read consists of only the final block it would not decrypted because | |
11004 | EVP_CipherUpdate() would correctly report zero bytes had been decrypted. | |
11005 | A misplaced 'break' also meant the decrypted final block might not be | |
11006 | copied until the next read. | |
11007 | [Steve Henson] | |
11008 | ||
11009 | *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added | |
11010 | a few extra parameters to the DH structure: these will be useful if | |
11011 | for example we want the value of 'q' or implement X9.42 DH. | |
11012 | [Steve Henson] | |
11013 | ||
11014 | *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and | |
11015 | provides hooks that allow the default DSA functions or functions on a | |
11016 | "per key" basis to be replaced. This allows hardware acceleration and | |
11017 | hardware key storage to be handled without major modification to the | |
11018 | library. Also added low level modexp hooks and CRYPTO_EX structure and | |
11019 | associated functions. | |
11020 | [Steve Henson] | |
11021 | ||
11022 | *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO | |
11023 | as "read only": it can't be written to and the buffer it points to will | |
11024 | not be freed. Reading from a read only BIO is much more efficient than | |
11025 | a normal memory BIO. This was added because there are several times when | |
11026 | an area of memory needs to be read from a BIO. The previous method was | |
11027 | to create a memory BIO and write the data to it, this results in two | |
11028 | copies of the data and an O(n^2) reading algorithm. There is a new | |
11029 | function BIO_new_mem_buf() which creates a read only memory BIO from | |
11030 | an area of memory. Also modified the PKCS#7 routines to use read only | |
11031 | memory BIOs. | |
11032 | [Steve Henson] | |
11033 | ||
11034 | *) Bugfix: ssl23_get_client_hello did not work properly when called in | |
11035 | state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of | |
11036 | a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read, | |
11037 | but a retry condition occurred while trying to read the rest. | |
11038 | [Bodo Moeller] | |
11039 | ||
11040 | *) The PKCS7_ENC_CONTENT_new() function was setting the content type as | |
11041 | NID_pkcs7_encrypted by default: this was wrong since this should almost | |
11042 | always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle | |
11043 | the encrypted data type: this is a more sensible place to put it and it | |
11044 | allows the PKCS#12 code to be tidied up that duplicated this | |
11045 | functionality. | |
11046 | [Steve Henson] | |
11047 | ||
11048 | *) Changed obj_dat.pl script so it takes its input and output files on | |
11049 | the command line. This should avoid shell escape redirection problems | |
11050 | under Win32. | |
11051 | [Steve Henson] | |
11052 | ||
11053 | *) Initial support for certificate extension requests, these are included | |
11054 | in things like Xenroll certificate requests. Included functions to allow | |
11055 | extensions to be obtained and added. | |
11056 | [Steve Henson] | |
11057 | ||
11058 | *) -crlf option to s_client and s_server for sending newlines as | |
11059 | CRLF (as required by many protocols). | |
11060 | [Bodo Moeller] | |
11061 | ||
11062 | Changes between 0.9.3a and 0.9.4 [09 Aug 1999] | |
11063 | ||
11064 | *) Install libRSAglue.a when OpenSSL is built with RSAref. | |
11065 | [Ralf S. Engelschall] | |
11066 | ||
11067 | *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency. | |
11068 | [Andrija Antonijevic <TheAntony2@bigfoot.com>] | |
11069 | ||
11070 | *) Fix -startdate and -enddate (which was missing) arguments to 'ca' | |
11071 | program. | |
11072 | [Steve Henson] | |
11073 | ||
11074 | *) New function DSA_dup_DH, which duplicates DSA parameters/keys as | |
11075 | DH parameters/keys (q is lost during that conversion, but the resulting | |
11076 | DH parameters contain its length). | |
11077 | ||
11078 | For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is | |
11079 | much faster than DH_generate_parameters (which creates parameters | |
11080 | where p = 2*q + 1), and also the smaller q makes DH computations | |
11081 | much more efficient (160-bit exponentiation instead of 1024-bit | |
11082 | exponentiation); so this provides a convenient way to support DHE | |
11083 | ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of | |
11084 | utter importance to use | |
11085 | SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE); | |
11086 | or | |
11087 | SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE); | |
11088 | when such DH parameters are used, because otherwise small subgroup | |
11089 | attacks may become possible! | |
11090 | [Bodo Moeller] | |
11091 | ||
11092 | *) Avoid memory leak in i2d_DHparams. | |
11093 | [Bodo Moeller] | |
11094 | ||
11095 | *) Allow the -k option to be used more than once in the enc program: | |
11096 | this allows the same encrypted message to be read by multiple recipients. | |
11097 | [Steve Henson] | |
11098 | ||
11099 | *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts | |
11100 | an ASN1_OBJECT to a text string. If the "no_name" parameter is set then | |
11101 | it will always use the numerical form of the OID, even if it has a short | |
11102 | or long name. | |
11103 | [Steve Henson] | |
11104 | ||
11105 | *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp | |
11106 | method only got called if p,q,dmp1,dmq1,iqmp components were present, | |
11107 | otherwise bn_mod_exp was called. In the case of hardware keys for example | |
11108 | no private key components need be present and it might store extra data | |
11109 | in the RSA structure, which cannot be accessed from bn_mod_exp. | |
11110 | By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for | |
11111 | private key operations. | |
11112 | [Steve Henson] | |
11113 | ||
11114 | *) Added support for SPARC Linux. | |
11115 | [Andy Polyakov] | |
11116 | ||
11117 | *) pem_password_cb function type incompatibly changed from | |
11118 | typedef int pem_password_cb(char *buf, int size, int rwflag); | |
11119 | to | |
11120 | ....(char *buf, int size, int rwflag, void *userdata); | |
11121 | so that applications can pass data to their callbacks: | |
11122 | The PEM[_ASN1]_{read,write}... functions and macros now take an | |
11123 | additional void * argument, which is just handed through whenever | |
11124 | the password callback is called. | |
11125 | [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller] | |
11126 | ||
11127 | New function SSL_CTX_set_default_passwd_cb_userdata. | |
11128 | ||
11129 | Compatibility note: As many C implementations push function arguments | |
11130 | onto the stack in reverse order, the new library version is likely to | |
11131 | interoperate with programs that have been compiled with the old | |
11132 | pem_password_cb definition (PEM_whatever takes some data that | |
11133 | happens to be on the stack as its last argument, and the callback | |
11134 | just ignores this garbage); but there is no guarantee whatsoever that | |
11135 | this will work. | |
11136 | ||
11137 | *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=... | |
11138 | (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused | |
11139 | problems not only on Windows, but also on some Unix platforms. | |
11140 | To avoid problematic command lines, these definitions are now in an | |
11141 | auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl | |
11142 | for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds). | |
11143 | [Bodo Moeller] | |
11144 | ||
11145 | *) MIPS III/IV assembler module is reimplemented. | |
11146 | [Andy Polyakov] | |
11147 | ||
11148 | *) More DES library cleanups: remove references to srand/rand and | |
11149 | delete an unused file. | |
11150 | [Ulf Möller] | |
11151 | ||
11152 | *) Add support for the the free Netwide assembler (NASM) under Win32, | |
11153 | since not many people have MASM (ml) and it can be hard to obtain. | |
11154 | This is currently experimental but it seems to work OK and pass all | |
11155 | the tests. Check out INSTALL.W32 for info. | |
11156 | [Steve Henson] | |
11157 | ||
11158 | *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections | |
11159 | without temporary keys kept an extra copy of the server key, | |
11160 | and connections with temporary keys did not free everything in case | |
11161 | of an error. | |
11162 | [Bodo Moeller] | |
11163 | ||
11164 | *) New function RSA_check_key and new openssl rsa option -check | |
11165 | for verifying the consistency of RSA keys. | |
11166 | [Ulf Moeller, Bodo Moeller] | |
11167 | ||
11168 | *) Various changes to make Win32 compile work: | |
11169 | 1. Casts to avoid "loss of data" warnings in p5_crpt2.c | |
11170 | 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned | |
11171 | comparison" warnings. | |
11172 | 3. Add sk_<TYPE>_sort to DEF file generator and do make update. | |
11173 | [Steve Henson] | |
11174 | ||
11175 | *) Add a debugging option to PKCS#5 v2 key generation function: when | |
11176 | you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and | |
11177 | derived keys are printed to stderr. | |
11178 | [Steve Henson] | |
11179 | ||
11180 | *) Copy the flags in ASN1_STRING_dup(). | |
11181 | [Roman E. Pavlov <pre@mo.msk.ru>] | |
11182 | ||
11183 | *) The x509 application mishandled signing requests containing DSA | |
11184 | keys when the signing key was also DSA and the parameters didn't match. | |
11185 | ||
11186 | It was supposed to omit the parameters when they matched the signing key: | |
11187 | the verifying software was then supposed to automatically use the CA's | |
11188 | parameters if they were absent from the end user certificate. | |
11189 | ||
11190 | Omitting parameters is no longer recommended. The test was also | |
11191 | the wrong way round! This was probably due to unusual behaviour in | |
11192 | EVP_cmp_parameters() which returns 1 if the parameters match. | |
11193 | This meant that parameters were omitted when they *didn't* match and | |
11194 | the certificate was useless. Certificates signed with 'ca' didn't have | |
11195 | this bug. | |
11196 | [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>] | |
11197 | ||
11198 | *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems. | |
11199 | The interface is as follows: | |
11200 | Applications can use | |
11201 | CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(), | |
11202 | CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop(); | |
11203 | "off" is now the default. | |
11204 | The library internally uses | |
11205 | CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(), | |
11206 | CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on() | |
11207 | to disable memory-checking temporarily. | |
11208 | ||
11209 | Some inconsistent states that previously were possible (and were | |
11210 | even the default) are now avoided. | |
11211 | ||
11212 | -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time | |
11213 | with each memory chunk allocated; this is occasionally more helpful | |
11214 | than just having a counter. | |
11215 | ||
11216 | -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID. | |
11217 | ||
11218 | -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future | |
11219 | extensions. | |
11220 | [Bodo Moeller] | |
11221 | ||
11222 | *) Introduce "mode" for SSL structures (with defaults in SSL_CTX), | |
11223 | which largely parallels "options", but is for changing API behaviour, | |
11224 | whereas "options" are about protocol behaviour. | |
11225 | Initial "mode" flags are: | |
11226 | ||
11227 | SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when | |
11228 | a single record has been written. | |
11229 | SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write | |
11230 | retries use the same buffer location. | |
11231 | (But all of the contents must be | |
11232 | copied!) | |
11233 | [Bodo Moeller] | |
11234 | ||
11235 | *) Bugfix: SSL_set_options ignored its parameter, only SSL_CTX_set_options | |
11236 | worked. | |
11237 | ||
11238 | *) Fix problems with no-hmac etc. | |
11239 | [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>] | |
11240 | ||
11241 | *) New functions RSA_get_default_method(), RSA_set_method() and | |
11242 | RSA_get_method(). These allows replacement of RSA_METHODs without having | |
11243 | to mess around with the internals of an RSA structure. | |
11244 | [Steve Henson] | |
11245 | ||
11246 | *) Fix memory leaks in DSA_do_sign and DSA_is_prime. | |
11247 | Also really enable memory leak checks in openssl.c and in some | |
11248 | test programs. | |
11249 | [Chad C. Mulligan, Bodo Moeller] | |
11250 | ||
11251 | *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess | |
11252 | up the length of negative integers. This has now been simplified to just | |
11253 | store the length when it is first determined and use it later, rather | |
11254 | than trying to keep track of where data is copied and updating it to | |
11255 | point to the end. | |
11256 | [Steve Henson, reported by Brien Wheeler | |
11257 | <bwheeler@authentica-security.com>] | |
11258 | ||
11259 | *) Add a new function PKCS7_signatureVerify. This allows the verification | |
11260 | of a PKCS#7 signature but with the signing certificate passed to the | |
11261 | function itself. This contrasts with PKCS7_dataVerify which assumes the | |
11262 | certificate is present in the PKCS#7 structure. This isn't always the | |
11263 | case: certificates can be omitted from a PKCS#7 structure and be | |
11264 | distributed by "out of band" means (such as a certificate database). | |
11265 | [Steve Henson] | |
11266 | ||
11267 | *) Complete the PEM_* macros with DECLARE_PEM versions to replace the | |
11268 | function prototypes in pem.h, also change util/mkdef.pl to add the | |
11269 | necessary function names. | |
11270 | [Steve Henson] | |
11271 | ||
11272 | *) mk1mf.pl (used by Windows builds) did not properly read the | |
11273 | options set by Configure in the top level Makefile, and Configure | |
11274 | was not even able to write more than one option correctly. | |
11275 | Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended. | |
11276 | [Bodo Moeller] | |
11277 | ||
11278 | *) New functions CONF_load_bio() and CONF_load_fp() to allow a config | |
11279 | file to be loaded from a BIO or FILE pointer. The BIO version will | |
11280 | for example allow memory BIOs to contain config info. | |
11281 | [Steve Henson] | |
11282 | ||
11283 | *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS. | |
11284 | Whoever hopes to achieve shared-library compatibility across versions | |
11285 | must use this, not the compile-time macro. | |
11286 | (Exercise 0.9.4: Which is the minimum library version required by | |
11287 | such programs?) | |
11288 | Note: All this applies only to multi-threaded programs, others don't | |
11289 | need locks. | |
11290 | [Bodo Moeller] | |
11291 | ||
11292 | *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests | |
11293 | through a BIO pair triggered the default case, i.e. | |
11294 | SSLerr(...,SSL_R_UNKNOWN_STATE). | |
11295 | [Bodo Moeller] | |
11296 | ||
11297 | *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications | |
11298 | can use the SSL library even if none of the specific BIOs is | |
11299 | appropriate. | |
11300 | [Bodo Moeller] | |
11301 | ||
11302 | *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value | |
11303 | for the encoded length. | |
11304 | [Jeon KyoungHo <khjeon@sds.samsung.co.kr>] | |
11305 | ||
11306 | *) Add initial documentation of the X509V3 functions. | |
11307 | [Steve Henson] | |
11308 | ||
11309 | *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and | |
11310 | PEM_write_bio_PKCS8PrivateKey() that are equivalent to | |
11311 | PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more | |
11312 | secure PKCS#8 private key format with a high iteration count. | |
11313 | [Steve Henson] | |
11314 | ||
11315 | *) Fix determination of Perl interpreter: A perl or perl5 | |
11316 | _directory_ in $PATH was also accepted as the interpreter. | |
11317 | [Ralf S. Engelschall] | |
11318 | ||
11319 | *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking | |
11320 | wrong with it but it was very old and did things like calling | |
11321 | PEM_ASN1_read() directly and used MD5 for the hash not to mention some | |
11322 | unusual formatting. | |
11323 | [Steve Henson] | |
11324 | ||
11325 | *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed | |
11326 | to use the new extension code. | |
11327 | [Steve Henson] | |
11328 | ||
11329 | *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c | |
11330 | with macros. This should make it easier to change their form, add extra | |
11331 | arguments etc. Fix a few PEM prototypes which didn't have cipher as a | |
11332 | constant. | |
11333 | [Steve Henson] | |
11334 | ||
11335 | *) Add to configuration table a new entry that can specify an alternative | |
11336 | name for unistd.h (for pre-POSIX systems); we need this for NeXTstep, | |
11337 | according to Mark Crispin <MRC@Panda.COM>. | |
11338 | [Bodo Moeller] | |
11339 | ||
11340 | #if 0 | |
11341 | *) DES CBC did not update the IV. Weird. | |
11342 | [Ben Laurie] | |
11343 | #else | |
11344 | des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does. | |
11345 | Changing the behaviour of the former might break existing programs -- | |
11346 | where IV updating is needed, des_ncbc_encrypt can be used. | |
11347 | #endif | |
11348 | ||
11349 | *) When bntest is run from "make test" it drives bc to check its | |
11350 | calculations, as well as internally checking them. If an internal check | |
11351 | fails, it needs to cause bc to give a non-zero result or make test carries | |
11352 | on without noticing the failure. Fixed. | |
11353 | [Ben Laurie] | |
11354 | ||
11355 | *) DES library cleanups. | |
11356 | [Ulf Möller] | |
11357 | ||
11358 | *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be | |
11359 | used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit | |
11360 | ciphers. NOTE: although the key derivation function has been verified | |
11361 | against some published test vectors it has not been extensively tested | |
11362 | yet. Added a -v2 "cipher" option to pkcs8 application to allow the use | |
11363 | of v2.0. | |
11364 | [Steve Henson] | |
11365 | ||
11366 | *) Instead of "mkdir -p", which is not fully portable, use new | |
11367 | Perl script "util/mkdir-p.pl". | |
11368 | [Bodo Moeller] | |
11369 | ||
11370 | *) Rewrite the way password based encryption (PBE) is handled. It used to | |
11371 | assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter | |
11372 | structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms | |
11373 | but doesn't apply to PKCS#5 v2.0 where it can be something else. Now | |
11374 | the 'parameter' field of the AlgorithmIdentifier is passed to the | |
11375 | underlying key generation function so it must do its own ASN1 parsing. | |
11376 | This has also changed the EVP_PBE_CipherInit() function which now has a | |
11377 | 'parameter' argument instead of literal salt and iteration count values | |
11378 | and the function EVP_PBE_ALGOR_CipherInit() has been deleted. | |
11379 | [Steve Henson] | |
11380 | ||
11381 | *) Support for PKCS#5 v1.5 compatible password based encryption algorithms | |
11382 | and PKCS#8 functionality. New 'pkcs8' application linked to openssl. | |
11383 | Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE | |
11384 | KEY" because this clashed with PKCS#8 unencrypted string. Since this | |
11385 | value was just used as a "magic string" and not used directly its | |
11386 | value doesn't matter. | |
11387 | [Steve Henson] | |
11388 | ||
11389 | *) Introduce some semblance of const correctness to BN. Shame C doesn't | |
11390 | support mutable. | |
11391 | [Ben Laurie] | |
11392 | ||
11393 | *) "linux-sparc64" configuration (ultrapenguin). | |
11394 | [Ray Miller <ray.miller@oucs.ox.ac.uk>] | |
11395 | "linux-sparc" configuration. | |
11396 | [Christian Forster <fo@hawo.stw.uni-erlangen.de>] | |
11397 | ||
11398 | *) config now generates no-xxx options for missing ciphers. | |
11399 | [Ulf Möller] | |
11400 | ||
11401 | *) Support the EBCDIC character set (work in progress). | |
11402 | File ebcdic.c not yet included because it has a different license. | |
11403 | [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>] | |
11404 | ||
11405 | *) Support BS2000/OSD-POSIX. | |
11406 | [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>] | |
11407 | ||
11408 | *) Make callbacks for key generation use void * instead of char *. | |
11409 | [Ben Laurie] | |
11410 | ||
11411 | *) Make S/MIME samples compile (not yet tested). | |
11412 | [Ben Laurie] | |
11413 | ||
11414 | *) Additional typesafe stacks. | |
11415 | [Ben Laurie] | |
11416 | ||
11417 | *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x). | |
11418 | [Bodo Moeller] | |
11419 | ||
11420 | ||
11421 | Changes between 0.9.3 and 0.9.3a [29 May 1999] | |
11422 | ||
11423 | *) New configuration variant "sco5-gcc". | |
11424 | ||
11425 | *) Updated some demos. | |
11426 | [Sean O Riordain, Wade Scholine] | |
11427 | ||
11428 | *) Add missing BIO_free at exit of pkcs12 application. | |
11429 | [Wu Zhigang] | |
11430 | ||
11431 | *) Fix memory leak in conf.c. | |
11432 | [Steve Henson] | |
11433 | ||
11434 | *) Updates for Win32 to assembler version of MD5. | |
11435 | [Steve Henson] | |
11436 | ||
11437 | *) Set #! path to perl in apps/der_chop to where we found it | |
11438 | instead of using a fixed path. | |
11439 | [Bodo Moeller] | |
11440 | ||
11441 | *) SHA library changes for irix64-mips4-cc. | |
11442 | [Andy Polyakov] | |
11443 | ||
11444 | *) Improvements for VMS support. | |
11445 | [Richard Levitte] | |
11446 | ||
11447 | ||
11448 | Changes between 0.9.2b and 0.9.3 [24 May 1999] | |
11449 | ||
11450 | *) Bignum library bug fix. IRIX 6 passes "make test" now! | |
11451 | This also avoids the problems with SC4.2 and unpatched SC5. | |
11452 | [Andy Polyakov <appro@fy.chalmers.se>] | |
11453 | ||
11454 | *) New functions sk_num, sk_value and sk_set to replace the previous macros. | |
11455 | These are required because of the typesafe stack would otherwise break | |
11456 | existing code. If old code used a structure member which used to be STACK | |
11457 | and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with | |
11458 | sk_num or sk_value it would produce an error because the num, data members | |
11459 | are not present in STACK_OF. Now it just produces a warning. sk_set | |
11460 | replaces the old method of assigning a value to sk_value | |
11461 | (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code | |
11462 | that does this will no longer work (and should use sk_set instead) but | |
11463 | this could be regarded as a "questionable" behaviour anyway. | |
11464 | [Steve Henson] | |
11465 | ||
11466 | *) Fix most of the other PKCS#7 bugs. The "experimental" code can now | |
11467 | correctly handle encrypted S/MIME data. | |
11468 | [Steve Henson] | |
11469 | ||
11470 | *) Change type of various DES function arguments from des_cblock | |
11471 | (which means, in function argument declarations, pointer to char) | |
11472 | to des_cblock * (meaning pointer to array with 8 char elements), | |
11473 | which allows the compiler to do more typechecking; it was like | |
11474 | that back in SSLeay, but with lots of ugly casts. | |
11475 | ||
11476 | Introduce new type const_des_cblock. | |
11477 | [Bodo Moeller] | |
11478 | ||
11479 | *) Reorganise the PKCS#7 library and get rid of some of the more obvious | |
11480 | problems: find RecipientInfo structure that matches recipient certificate | |
11481 | and initialise the ASN1 structures properly based on passed cipher. | |
11482 | [Steve Henson] | |
11483 | ||
11484 | *) Belatedly make the BN tests actually check the results. | |
11485 | [Ben Laurie] | |
11486 | ||
11487 | *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion | |
11488 | to and from BNs: it was completely broken. New compilation option | |
11489 | NEG_PUBKEY_BUG to allow for some broken certificates that encode public | |
11490 | key elements as negative integers. | |
11491 | [Steve Henson] | |
11492 | ||
11493 | *) Reorganize and speed up MD5. | |
11494 | [Andy Polyakov <appro@fy.chalmers.se>] | |
11495 | ||
11496 | *) VMS support. | |
11497 | [Richard Levitte <richard@levitte.org>] | |
11498 | ||
11499 | *) New option -out to asn1parse to allow the parsed structure to be | |
11500 | output to a file. This is most useful when combined with the -strparse | |
11501 | option to examine the output of things like OCTET STRINGS. | |
11502 | [Steve Henson] | |
11503 | ||
11504 | *) Make SSL library a little more fool-proof by not requiring any longer | |
11505 | that SSL_set_{accept,connect}_state be called before | |
11506 | SSL_{accept,connect} may be used (SSL_set_..._state is omitted | |
11507 | in many applications because usually everything *appeared* to work as | |
11508 | intended anyway -- now it really works as intended). | |
11509 | [Bodo Moeller] | |
11510 | ||
11511 | *) Move openssl.cnf out of lib/. | |
11512 | [Ulf Möller] | |
11513 | ||
11514 | *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall | |
11515 | -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes | |
11516 | -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+ | |
11517 | [Ralf S. Engelschall] | |
11518 | ||
11519 | *) Various fixes to the EVP and PKCS#7 code. It may now be able to | |
11520 | handle PKCS#7 enveloped data properly. | |
11521 | [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve] | |
11522 | ||
11523 | *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of | |
11524 | copying pointers. The cert_st handling is changed by this in | |
11525 | various ways (and thus what used to be known as ctx->default_cert | |
11526 | is now called ctx->cert, since we don't resort to s->ctx->[default_]cert | |
11527 | any longer when s->cert does not give us what we need). | |
11528 | ssl_cert_instantiate becomes obsolete by this change. | |
11529 | As soon as we've got the new code right (possibly it already is?), | |
11530 | we have solved a couple of bugs of the earlier code where s->cert | |
11531 | was used as if it could not have been shared with other SSL structures. | |
11532 | ||
11533 | Note that using the SSL API in certain dirty ways now will result | |
11534 | in different behaviour than observed with earlier library versions: | |
11535 | Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx) | |
11536 | does not influence s as it used to. | |
11537 | ||
11538 | In order to clean up things more thoroughly, inside SSL_SESSION | |
11539 | we don't use CERT any longer, but a new structure SESS_CERT | |
11540 | that holds per-session data (if available); currently, this is | |
11541 | the peer's certificate chain and, for clients, the server's certificate | |
11542 | and temporary key. CERT holds only those values that can have | |
11543 | meaningful defaults in an SSL_CTX. | |
11544 | [Bodo Moeller] | |
11545 | ||
11546 | *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure | |
11547 | from the internal representation. Various PKCS#7 fixes: remove some | |
11548 | evil casts and set the enc_dig_alg field properly based on the signing | |
11549 | key type. | |
11550 | [Steve Henson] | |
11551 | ||
11552 | *) Allow PKCS#12 password to be set from the command line or the | |
11553 | environment. Let 'ca' get its config file name from the environment | |
11554 | variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req' | |
11555 | and 'x509'). | |
11556 | [Steve Henson] | |
11557 | ||
11558 | *) Allow certificate policies extension to use an IA5STRING for the | |
11559 | organization field. This is contrary to the PKIX definition but | |
11560 | VeriSign uses it and IE5 only recognises this form. Document 'x509' | |
11561 | extension option. | |
11562 | [Steve Henson] | |
11563 | ||
11564 | *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic, | |
11565 | without disallowing inline assembler and the like for non-pedantic builds. | |
11566 | [Ben Laurie] | |
11567 | ||
11568 | *) Support Borland C++ builder. | |
11569 | [Janez Jere <jj@void.si>, modified by Ulf Möller] | |
11570 | ||
11571 | *) Support Mingw32. | |
11572 | [Ulf Möller] | |
11573 | ||
11574 | *) SHA-1 cleanups and performance enhancements. | |
11575 | [Andy Polyakov <appro@fy.chalmers.se>] | |
11576 | ||
11577 | *) Sparc v8plus assembler for the bignum library. | |
11578 | [Andy Polyakov <appro@fy.chalmers.se>] | |
11579 | ||
11580 | *) Accept any -xxx and +xxx compiler options in Configure. | |
11581 | [Ulf Möller] | |
11582 | ||
11583 | *) Update HPUX configuration. | |
11584 | [Anonymous] | |
11585 | ||
11586 | *) Add missing sk_<type>_unshift() function to safestack.h | |
11587 | [Ralf S. Engelschall] | |
11588 | ||
11589 | *) New function SSL_CTX_use_certificate_chain_file that sets the | |
11590 | "extra_cert"s in addition to the certificate. (This makes sense | |
11591 | only for "PEM" format files, as chains as a whole are not | |
11592 | DER-encoded.) | |
11593 | [Bodo Moeller] | |
11594 | ||
11595 | *) Support verify_depth from the SSL API. | |
11596 | x509_vfy.c had what can be considered an off-by-one-error: | |
11597 | Its depth (which was not part of the external interface) | |
11598 | was actually counting the number of certificates in a chain; | |
11599 | now it really counts the depth. | |
11600 | [Bodo Moeller] | |
11601 | ||
11602 | *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used | |
11603 | instead of X509err, which often resulted in confusing error | |
11604 | messages since the error codes are not globally unique | |
11605 | (e.g. an alleged error in ssl3_accept when a certificate | |
11606 | didn't match the private key). | |
11607 | ||
11608 | *) New function SSL_CTX_set_session_id_context that allows to set a default | |
11609 | value (so that you don't need SSL_set_session_id_context for each | |
11610 | connection using the SSL_CTX). | |
11611 | [Bodo Moeller] | |
11612 | ||
11613 | *) OAEP decoding bug fix. | |
11614 | [Ulf Möller] | |
11615 | ||
11616 | *) Support INSTALL_PREFIX for package builders, as proposed by | |
11617 | David Harris. | |
11618 | [Bodo Moeller] | |
11619 | ||
11620 | *) New Configure options "threads" and "no-threads". For systems | |
11621 | where the proper compiler options are known (currently Solaris | |
11622 | and Linux), "threads" is the default. | |
11623 | [Bodo Moeller] | |
11624 | ||
11625 | *) New script util/mklink.pl as a faster substitute for util/mklink.sh. | |
11626 | [Bodo Moeller] | |
11627 | ||
11628 | *) Install various scripts to $(OPENSSLDIR)/misc, not to | |
11629 | $(INSTALLTOP)/bin -- they shouldn't clutter directories | |
11630 | such as /usr/local/bin. | |
11631 | [Bodo Moeller] | |
11632 | ||
11633 | *) "make linux-shared" to build shared libraries. | |
11634 | [Niels Poppe <niels@netbox.org>] | |
11635 | ||
11636 | *) New Configure option no-<cipher> (rsa, idea, rc5, ...). | |
11637 | [Ulf Möller] | |
11638 | ||
11639 | *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for | |
11640 | extension adding in x509 utility. | |
11641 | [Steve Henson] | |
11642 | ||
11643 | *) Remove NOPROTO sections and error code comments. | |
11644 | [Ulf Möller] | |
11645 | ||
11646 | *) Partial rewrite of the DEF file generator to now parse the ANSI | |
11647 | prototypes. | |
11648 | [Steve Henson] | |
11649 | ||
11650 | *) New Configure options --prefix=DIR and --openssldir=DIR. | |
11651 | [Ulf Möller] | |
11652 | ||
11653 | *) Complete rewrite of the error code script(s). It is all now handled | |
11654 | by one script at the top level which handles error code gathering, | |
11655 | header rewriting and C source file generation. It should be much better | |
11656 | than the old method: it now uses a modified version of Ulf's parser to | |
11657 | read the ANSI prototypes in all header files (thus the old K&R definitions | |
11658 | aren't needed for error creation any more) and do a better job of | |
11659 | translating function codes into names. The old 'ASN1 error code imbedded | |
11660 | in a comment' is no longer necessary and it doesn't use .err files which | |
11661 | have now been deleted. Also the error code call doesn't have to appear all | |
11662 | on one line (which resulted in some large lines...). | |
11663 | [Steve Henson] | |
11664 | ||
11665 | *) Change #include filenames from <foo.h> to <openssl/foo.h>. | |
11666 | [Bodo Moeller] | |
11667 | ||
11668 | *) Change behaviour of ssl2_read when facing length-0 packets: Don't return | |
11669 | 0 (which usually indicates a closed connection), but continue reading. | |
11670 | [Bodo Moeller] | |
11671 | ||
11672 | *) Fix some race conditions. | |
11673 | [Bodo Moeller] | |
11674 | ||
11675 | *) Add support for CRL distribution points extension. Add Certificate | |
11676 | Policies and CRL distribution points documentation. | |
11677 | [Steve Henson] | |
11678 | ||
11679 | *) Move the autogenerated header file parts to crypto/opensslconf.h. | |
11680 | [Ulf Möller] | |
11681 | ||
11682 | *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of | |
11683 | 8 of keying material. Merlin has also confirmed interop with this fix | |
11684 | between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0. | |
11685 | [Merlin Hughes <merlin@baltimore.ie>] | |
11686 | ||
11687 | *) Fix lots of warnings. | |
11688 | [Richard Levitte <levitte@stacken.kth.se>] | |
11689 | ||
11690 | *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if | |
11691 | the directory spec didn't end with a LIST_SEPARATOR_CHAR. | |
11692 | [Richard Levitte <levitte@stacken.kth.se>] | |
11693 | ||
11694 | *) Fix problems with sizeof(long) == 8. | |
11695 | [Andy Polyakov <appro@fy.chalmers.se>] | |
11696 | ||
11697 | *) Change functions to ANSI C. | |
11698 | [Ulf Möller] | |
11699 | ||
11700 | *) Fix typos in error codes. | |
11701 | [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller] | |
11702 | ||
11703 | *) Remove defunct assembler files from Configure. | |
11704 | [Ulf Möller] | |
11705 | ||
11706 | *) SPARC v8 assembler BIGNUM implementation. | |
11707 | [Andy Polyakov <appro@fy.chalmers.se>] | |
11708 | ||
11709 | *) Support for Certificate Policies extension: both print and set. | |
11710 | Various additions to support the r2i method this uses. | |
11711 | [Steve Henson] | |
11712 | ||
11713 | *) A lot of constification, and fix a bug in X509_NAME_oneline() that could | |
11714 | return a const string when you are expecting an allocated buffer. | |
11715 | [Ben Laurie] | |
11716 | ||
11717 | *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE | |
11718 | types DirectoryString and DisplayText. | |
11719 | [Steve Henson] | |
11720 | ||
11721 | *) Add code to allow r2i extensions to access the configuration database, | |
11722 | add an LHASH database driver and add several ctx helper functions. | |
11723 | [Steve Henson] | |
11724 | ||
11725 | *) Fix an evil bug in bn_expand2() which caused various BN functions to | |
11726 | fail when they extended the size of a BIGNUM. | |
11727 | [Steve Henson] | |
11728 | ||
11729 | *) Various utility functions to handle SXNet extension. Modify mkdef.pl to | |
11730 | support typesafe stack. | |
11731 | [Steve Henson] | |
11732 | ||
11733 | *) Fix typo in SSL_[gs]et_options(). | |
11734 | [Nils Frostberg <nils@medcom.se>] | |
11735 | ||
11736 | *) Delete various functions and files that belonged to the (now obsolete) | |
11737 | old X509V3 handling code. | |
11738 | [Steve Henson] | |
11739 | ||
11740 | *) New Configure option "rsaref". | |
11741 | [Ulf Möller] | |
11742 | ||
11743 | *) Don't auto-generate pem.h. | |
11744 | [Bodo Moeller] | |
11745 | ||
11746 | *) Introduce type-safe ASN.1 SETs. | |
11747 | [Ben Laurie] | |
11748 | ||
11749 | *) Convert various additional casted stacks to type-safe STACK_OF() variants. | |
11750 | [Ben Laurie, Ralf S. Engelschall, Steve Henson] | |
11751 | ||
11752 | *) Introduce type-safe STACKs. This will almost certainly break lots of code | |
11753 | that links with OpenSSL (well at least cause lots of warnings), but fear | |
11754 | not: the conversion is trivial, and it eliminates loads of evil casts. A | |
11755 | few STACKed things have been converted already. Feel free to convert more. | |
11756 | In the fullness of time, I'll do away with the STACK type altogether. | |
11757 | [Ben Laurie] | |
11758 | ||
11759 | *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate | |
11760 | specified in <certfile> by updating the entry in the index.txt file. | |
11761 | This way one no longer has to edit the index.txt file manually for | |
11762 | revoking a certificate. The -revoke option does the gory details now. | |
11763 | [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall] | |
11764 | ||
11765 | *) Fix `openssl crl -noout -text' combination where `-noout' killed the | |
11766 | `-text' option at all and this way the `-noout -text' combination was | |
11767 | inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'. | |
11768 | [Ralf S. Engelschall] | |
11769 | ||
11770 | *) Make sure a corresponding plain text error message exists for the | |
11771 | X509_V_ERR_CERT_REVOKED/23 error number which can occur when a | |
11772 | verify callback function determined that a certificate was revoked. | |
11773 | [Ralf S. Engelschall] | |
11774 | ||
11775 | *) Bugfix: In test/testenc, don't test "openssl <cipher>" for | |
11776 | ciphers that were excluded, e.g. by -DNO_IDEA. Also, test | |
11777 | all available ciphers including rc5, which was forgotten until now. | |
11778 | In order to let the testing shell script know which algorithms | |
11779 | are available, a new (up to now undocumented) command | |
11780 | "openssl list-cipher-commands" is used. | |
11781 | [Bodo Moeller] | |
11782 | ||
11783 | *) Bugfix: s_client occasionally would sleep in select() when | |
11784 | it should have checked SSL_pending() first. | |
11785 | [Bodo Moeller] | |
11786 | ||
11787 | *) New functions DSA_do_sign and DSA_do_verify to provide access to | |
11788 | the raw DSA values prior to ASN.1 encoding. | |
11789 | [Ulf Möller] | |
11790 | ||
11791 | *) Tweaks to Configure | |
11792 | [Niels Poppe <niels@netbox.org>] | |
11793 | ||
11794 | *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support, | |
11795 | yet... | |
11796 | [Steve Henson] | |
11797 | ||
11798 | *) New variables $(RANLIB) and $(PERL) in the Makefiles. | |
11799 | [Ulf Möller] | |
11800 | ||
11801 | *) New config option to avoid instructions that are illegal on the 80386. | |
11802 | The default code is faster, but requires at least a 486. | |
11803 | [Ulf Möller] | |
11804 | ||
11805 | *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and | |
11806 | SSL2_SERVER_VERSION (not used at all) macros, which are now the | |
11807 | same as SSL2_VERSION anyway. | |
11808 | [Bodo Moeller] | |
11809 | ||
11810 | *) New "-showcerts" option for s_client. | |
11811 | [Bodo Moeller] | |
11812 | ||
11813 | *) Still more PKCS#12 integration. Add pkcs12 application to openssl | |
11814 | application. Various cleanups and fixes. | |
11815 | [Steve Henson] | |
11816 | ||
11817 | *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and | |
11818 | modify error routines to work internally. Add error codes and PBE init | |
11819 | to library startup routines. | |
11820 | [Steve Henson] | |
11821 | ||
11822 | *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and | |
11823 | packing functions to asn1 and evp. Changed function names and error | |
11824 | codes along the way. | |
11825 | [Steve Henson] | |
11826 | ||
11827 | *) PKCS12 integration: and so it begins... First of several patches to | |
11828 | slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12 | |
11829 | objects to objects.h | |
11830 | [Steve Henson] | |
11831 | ||
11832 | *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1 | |
11833 | and display support for Thawte strong extranet extension. | |
11834 | [Steve Henson] | |
11835 | ||
11836 | *) Add LinuxPPC support. | |
11837 | [Jeff Dubrule <igor@pobox.org>] | |
11838 | ||
11839 | *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to | |
11840 | bn_div_words in alpha.s. | |
11841 | [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie] | |
11842 | ||
11843 | *) Make sure the RSA OAEP test is skipped under -DRSAref because | |
11844 | OAEP isn't supported when OpenSSL is built with RSAref. | |
11845 | [Ulf Moeller <ulf@fitug.de>] | |
11846 | ||
11847 | *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h | |
11848 | so they no longer are missing under -DNOPROTO. | |
11849 | [Soren S. Jorvang <soren@t.dk>] | |
11850 | ||
11851 | ||
11852 | Changes between 0.9.1c and 0.9.2b [22 Mar 1999] | |
11853 | ||
11854 | *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still | |
11855 | doesn't work when the session is reused. Coming soon! | |
11856 | [Ben Laurie] | |
11857 | ||
11858 | *) Fix a security hole, that allows sessions to be reused in the wrong | |
11859 | context thus bypassing client cert protection! All software that uses | |
11860 | client certs and session caches in multiple contexts NEEDS PATCHING to | |
11861 | allow session reuse! A fuller solution is in the works. | |
11862 | [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)] | |
11863 | ||
11864 | *) Some more source tree cleanups (removed obsolete files | |
11865 | crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed | |
11866 | permission on "config" script to be executable) and a fix for the INSTALL | |
11867 | document. | |
11868 | [Ulf Moeller <ulf@fitug.de>] | |
11869 | ||
11870 | *) Remove some legacy and erroneous uses of malloc, free instead of | |
11871 | Malloc, Free. | |
11872 | [Lennart Bang <lob@netstream.se>, with minor changes by Steve] | |
11873 | ||
11874 | *) Make rsa_oaep_test return non-zero on error. | |
11875 | [Ulf Moeller <ulf@fitug.de>] | |
11876 | ||
11877 | *) Add support for native Solaris shared libraries. Configure | |
11878 | solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice | |
11879 | if someone would make that last step automatic. | |
11880 | [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>] | |
11881 | ||
11882 | *) ctx_size was not built with the right compiler during "make links". Fixed. | |
11883 | [Ben Laurie] | |
11884 | ||
11885 | *) Change the meaning of 'ALL' in the cipher list. It now means "everything | |
11886 | except NULL ciphers". This means the default cipher list will no longer | |
11887 | enable NULL ciphers. They need to be specifically enabled e.g. with | |
11888 | the string "DEFAULT:eNULL". | |
11889 | [Steve Henson] | |
11890 | ||
11891 | *) Fix to RSA private encryption routines: if p < q then it would | |
11892 | occasionally produce an invalid result. This will only happen with | |
11893 | externally generated keys because OpenSSL (and SSLeay) ensure p > q. | |
11894 | [Steve Henson] | |
11895 | ||
11896 | *) Be less restrictive and allow also `perl util/perlpath.pl | |
11897 | /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin', | |
11898 | because this way one can also use an interpreter named `perl5' (which is | |
11899 | usually the name of Perl 5.xxx on platforms where an Perl 4.x is still | |
11900 | installed as `perl'). | |
11901 | [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>] | |
11902 | ||
11903 | *) Let util/clean-depend.pl work also with older Perl 5.00x versions. | |
11904 | [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>] | |
11905 | ||
11906 | *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add | |
11907 | advapi32.lib to Win32 build and change the pem test comparison | |
11908 | to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the | |
11909 | suggestion). Fix misplaced ASNI prototypes and declarations in evp.h | |
11910 | and crypto/des/ede_cbcm_enc.c. | |
11911 | [Steve Henson] | |
11912 | ||
11913 | *) DES quad checksum was broken on big-endian architectures. Fixed. | |
11914 | [Ben Laurie] | |
11915 | ||
11916 | *) Comment out two functions in bio.h that aren't implemented. Fix up the | |
11917 | Win32 test batch file so it (might) work again. The Win32 test batch file | |
11918 | is horrible: I feel ill.... | |
11919 | [Steve Henson] | |
11920 | ||
11921 | *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected | |
11922 | in e_os.h. Audit of header files to check ANSI and non ANSI | |
11923 | sections: 10 functions were absent from non ANSI section and not exported | |
11924 | from Windows DLLs. Fixed up libeay.num for new functions. | |
11925 | [Steve Henson] | |
11926 | ||
11927 | *) Make `openssl version' output lines consistent. | |
11928 | [Ralf S. Engelschall] | |
11929 | ||
11930 | *) Fix Win32 symbol export lists for BIO functions: Added | |
11931 | BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data | |
11932 | to ms/libeay{16,32}.def. | |
11933 | [Ralf S. Engelschall] | |
11934 | ||
11935 | *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled | |
11936 | fine under Unix and passes some trivial tests I've now added. But the | |
11937 | whole stuff is horribly incomplete, so a README.1ST with a disclaimer was | |
11938 | added to make sure no one expects that this stuff really works in the | |
11939 | OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources | |
11940 | up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and | |
11941 | openssl_bio.xs. | |
11942 | [Ralf S. Engelschall] | |
11943 | ||
11944 | *) Fix the generation of two part addresses in perl. | |
11945 | [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie] | |
11946 | ||
11947 | *) Add config entry for Linux on MIPS. | |
11948 | [John Tobey <jtobey@channel1.com>] | |
11949 | ||
11950 | *) Make links whenever Configure is run, unless we are on Windoze. | |
11951 | [Ben Laurie] | |
11952 | ||
11953 | *) Permit extensions to be added to CRLs using crl_section in openssl.cnf. | |
11954 | Currently only issuerAltName and AuthorityKeyIdentifier make any sense | |
11955 | in CRLs. | |
11956 | [Steve Henson] | |
11957 | ||
11958 | *) Add a useful kludge to allow package maintainers to specify compiler and | |
11959 | other platforms details on the command line without having to patch the | |
11960 | Configure script everytime: One now can use ``perl Configure | |
11961 | <id>:<details>'', i.e. platform ids are allowed to have details appended | |
11962 | to them (separated by colons). This is treated as there would be a static | |
11963 | pre-configured entry in Configure's %table under key <id> with value | |
11964 | <details> and ``perl Configure <id>'' is called. So, when you want to | |
11965 | perform a quick test-compile under FreeBSD 3.1 with pgcc and without | |
11966 | assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"'' | |
11967 | now, which overrides the FreeBSD-elf entry on-the-fly. | |
11968 | [Ralf S. Engelschall] | |
11969 | ||
11970 | *) Disable new TLS1 ciphersuites by default: they aren't official yet. | |
11971 | [Ben Laurie] | |
11972 | ||
11973 | *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified | |
11974 | on the `perl Configure ...' command line. This way one can compile | |
11975 | OpenSSL libraries with Position Independent Code (PIC) which is needed | |
11976 | for linking it into DSOs. | |
11977 | [Ralf S. Engelschall] | |
11978 | ||
11979 | *) Remarkably, export ciphers were totally broken and no-one had noticed! | |
11980 | Fixed. | |
11981 | [Ben Laurie] | |
11982 | ||
11983 | *) Cleaned up the LICENSE document: The official contact for any license | |
11984 | questions now is the OpenSSL core team under openssl-core@openssl.org. | |
11985 | And add a paragraph about the dual-license situation to make sure people | |
11986 | recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply | |
11987 | to the OpenSSL toolkit. | |
11988 | [Ralf S. Engelschall] | |
11989 | ||
11990 | *) General source tree makefile cleanups: Made `making xxx in yyy...' | |
11991 | display consistent in the source tree and replaced `/bin/rm' by `rm'. | |
11992 | Additionally cleaned up the `make links' target: Remove unnecessary | |
11993 | semicolons, subsequent redundant removes, inline point.sh into mklink.sh | |
11994 | to speed processing and no longer clutter the display with confusing | |
11995 | stuff. Instead only the actually done links are displayed. | |
11996 | [Ralf S. Engelschall] | |
11997 | ||
11998 | *) Permit null encryption ciphersuites, used for authentication only. It used | |
11999 | to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this. | |
12000 | It is now necessary to set SSL_FORBID_ENULL to prevent the use of null | |
12001 | encryption. | |
12002 | [Ben Laurie] | |
12003 | ||
12004 | *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder | |
12005 | signed attributes when verifying signatures (this would break them), | |
12006 | the detached data encoding was wrong and public keys obtained using | |
12007 | X509_get_pubkey() weren't freed. | |
12008 | [Steve Henson] | |
12009 | ||
12010 | *) Add text documentation for the BUFFER functions. Also added a work around | |
12011 | to a Win95 console bug. This was triggered by the password read stuff: the | |
12012 | last character typed gets carried over to the next fread(). If you were | |
12013 | generating a new cert request using 'req' for example then the last | |
12014 | character of the passphrase would be CR which would then enter the first | |
12015 | field as blank. | |
12016 | [Steve Henson] | |
12017 | ||
12018 | *) Added the new `Includes OpenSSL Cryptography Software' button as | |
12019 | doc/openssl_button.{gif,html} which is similar in style to the old SSLeay | |
12020 | button and can be used by applications based on OpenSSL to show the | |
12021 | relationship to the OpenSSL project. | |
12022 | [Ralf S. Engelschall] | |
12023 | ||
12024 | *) Remove confusing variables in function signatures in files | |
12025 | ssl/ssl_lib.c and ssl/ssl.h. | |
12026 | [Lennart Bong <lob@kulthea.stacken.kth.se>] | |
12027 | ||
12028 | *) Don't install bss_file.c under PREFIX/include/ | |
12029 | [Lennart Bong <lob@kulthea.stacken.kth.se>] | |
12030 | ||
12031 | *) Get the Win32 compile working again. Modify mkdef.pl so it can handle | |
12032 | functions that return function pointers and has support for NT specific | |
12033 | stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various | |
12034 | #ifdef WIN32 and WINNTs sprinkled about the place and some changes from | |
12035 | unsigned to signed types: this was killing the Win32 compile. | |
12036 | [Steve Henson] | |
12037 | ||
12038 | *) Add new certificate file to stack functions, | |
12039 | SSL_add_dir_cert_subjects_to_stack() and | |
12040 | SSL_add_file_cert_subjects_to_stack(). These largely supplant | |
12041 | SSL_load_client_CA_file(), and can be used to add multiple certs easily | |
12042 | to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()). | |
12043 | This means that Apache-SSL and similar packages don't have to mess around | |
12044 | to add as many CAs as they want to the preferred list. | |
12045 | [Ben Laurie] | |
12046 | ||
12047 | *) Experiment with doxygen documentation. Currently only partially applied to | |
12048 | ssl/ssl_lib.c. | |
12049 | See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with | |
12050 | openssl.doxy as the configuration file. | |
12051 | [Ben Laurie] | |
12052 | ||
12053 | *) Get rid of remaining C++-style comments which strict C compilers hate. | |
12054 | [Ralf S. Engelschall, pointed out by Carlos Amengual] | |
12055 | ||
12056 | *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not | |
12057 | compiled in by default: it has problems with large keys. | |
12058 | [Steve Henson] | |
12059 | ||
12060 | *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and | |
12061 | DH private keys and/or callback functions which directly correspond to | |
12062 | their SSL_CTX_xxx() counterparts but work on a per-connection basis. This | |
12063 | is needed for applications which have to configure certificates on a | |
12064 | per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis | |
12065 | (e.g. s_server). | |
12066 | For the RSA certificate situation is makes no difference, but | |
12067 | for the DSA certificate situation this fixes the "no shared cipher" | |
12068 | problem where the OpenSSL cipher selection procedure failed because the | |
12069 | temporary keys were not overtaken from the context and the API provided | |
12070 | no way to reconfigure them. | |
12071 | The new functions now let applications reconfigure the stuff and they | |
12072 | are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh, | |
12073 | SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new | |
12074 | non-public-API function ssl_cert_instantiate() is used as a helper | |
12075 | function and also to reduce code redundancy inside ssl_rsa.c. | |
12076 | [Ralf S. Engelschall] | |
12077 | ||
12078 | *) Move s_server -dcert and -dkey options out of the undocumented feature | |
12079 | area because they are useful for the DSA situation and should be | |
12080 | recognized by the users. | |
12081 | [Ralf S. Engelschall] | |
12082 | ||
12083 | *) Fix the cipher decision scheme for export ciphers: the export bits are | |
12084 | *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within | |
12085 | SSL_EXP_MASK. So, the original variable has to be used instead of the | |
12086 | already masked variable. | |
12087 | [Richard Levitte <levitte@stacken.kth.se>] | |
12088 | ||
12089 | *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c | |
12090 | [Richard Levitte <levitte@stacken.kth.se>] | |
12091 | ||
12092 | *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal() | |
12093 | from `int' to `unsigned int' because it's a length and initialized by | |
12094 | EVP_DigestFinal() which expects an `unsigned int *'. | |
12095 | [Richard Levitte <levitte@stacken.kth.se>] | |
12096 | ||
12097 | *) Don't hard-code path to Perl interpreter on shebang line of Configure | |
12098 | script. Instead use the usual Shell->Perl transition trick. | |
12099 | [Ralf S. Engelschall] | |
12100 | ||
12101 | *) Make `openssl x509 -noout -modulus' functional also for DSA certificates | |
12102 | (in addition to RSA certificates) to match the behaviour of `openssl dsa | |
12103 | -noout -modulus' as it's already the case for `openssl rsa -noout | |
12104 | -modulus'. For RSA the -modulus is the real "modulus" while for DSA | |
12105 | currently the public key is printed (a decision which was already done by | |
12106 | `openssl dsa -modulus' in the past) which serves a similar purpose. | |
12107 | Additionally the NO_RSA no longer completely removes the whole -modulus | |
12108 | option; it now only avoids using the RSA stuff. Same applies to NO_DSA | |
12109 | now, too. | |
12110 | [Ralf S. Engelschall] | |
12111 | ||
12112 | *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested | |
12113 | BIO. See the source (crypto/evp/bio_ok.c) for more info. | |
12114 | [Arne Ansper <arne@ats.cyber.ee>] | |
12115 | ||
12116 | *) Dump the old yucky req code that tried (and failed) to allow raw OIDs | |
12117 | to be added. Now both 'req' and 'ca' can use new objects defined in the | |
12118 | config file. | |
12119 | [Steve Henson] | |
12120 | ||
12121 | *) Add cool BIO that does syslog (or event log on NT). | |
12122 | [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie] | |
12123 | ||
12124 | *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5, | |
12125 | TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and | |
12126 | TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher | |
12127 | Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt. | |
12128 | [Ben Laurie] | |
12129 | ||
12130 | *) Add preliminary config info for new extension code. | |
12131 | [Steve Henson] | |
12132 | ||
12133 | *) Make RSA_NO_PADDING really use no padding. | |
12134 | [Ulf Moeller <ulf@fitug.de>] | |
12135 | ||
12136 | *) Generate errors when private/public key check is done. | |
12137 | [Ben Laurie] | |
12138 | ||
12139 | *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support | |
12140 | for some CRL extensions and new objects added. | |
12141 | [Steve Henson] | |
12142 | ||
12143 | *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private | |
12144 | key usage extension and fuller support for authority key id. | |
12145 | [Steve Henson] | |
12146 | ||
12147 | *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved | |
12148 | padding method for RSA, which is recommended for new applications in PKCS | |
12149 | #1 v2.0 (RFC 2437, October 1998). | |
12150 | OAEP (Optimal Asymmetric Encryption Padding) has better theoretical | |
12151 | foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure | |
12152 | against Bleichbacher's attack on RSA. | |
12153 | [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by | |
12154 | Ben Laurie] | |
12155 | ||
12156 | *) Updates to the new SSL compression code | |
12157 | [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] | |
12158 | ||
12159 | *) Fix so that the version number in the master secret, when passed | |
12160 | via RSA, checks that if TLS was proposed, but we roll back to SSLv3 | |
12161 | (because the server will not accept higher), that the version number | |
12162 | is 0x03,0x01, not 0x03,0x00 | |
12163 | [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] | |
12164 | ||
12165 | *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory | |
12166 | leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes | |
12167 | in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c | |
12168 | [Steve Henson] | |
12169 | ||
12170 | *) Support for RAW extensions where an arbitrary extension can be | |
12171 | created by including its DER encoding. See apps/openssl.cnf for | |
12172 | an example. | |
12173 | [Steve Henson] | |
12174 | ||
12175 | *) Make sure latest Perl versions don't interpret some generated C array | |
12176 | code as Perl array code in the crypto/err/err_genc.pl script. | |
12177 | [Lars Weber <3weber@informatik.uni-hamburg.de>] | |
12178 | ||
12179 | *) Modify ms/do_ms.bat to not generate assembly language makefiles since | |
12180 | not many people have the assembler. Various Win32 compilation fixes and | |
12181 | update to the INSTALL.W32 file with (hopefully) more accurate Win32 | |
12182 | build instructions. | |
12183 | [Steve Henson] | |
12184 | ||
12185 | *) Modify configure script 'Configure' to automatically create crypto/date.h | |
12186 | file under Win32 and also build pem.h from pem.org. New script | |
12187 | util/mkfiles.pl to create the MINFO file on environments that can't do a | |
12188 | 'make files': perl util/mkfiles.pl >MINFO should work. | |
12189 | [Steve Henson] | |
12190 | ||
12191 | *) Major rework of DES function declarations, in the pursuit of correctness | |
12192 | and purity. As a result, many evil casts evaporated, and some weirdness, | |
12193 | too. You may find this causes warnings in your code. Zapping your evil | |
12194 | casts will probably fix them. Mostly. | |
12195 | [Ben Laurie] | |
12196 | ||
12197 | *) Fix for a typo in asn1.h. Bug fix to object creation script | |
12198 | obj_dat.pl. It considered a zero in an object definition to mean | |
12199 | "end of object": none of the objects in objects.h have any zeros | |
12200 | so it wasn't spotted. | |
12201 | [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>] | |
12202 | ||
12203 | *) Add support for Triple DES Cipher Block Chaining with Output Feedback | |
12204 | Masking (CBCM). In the absence of test vectors, the best I have been able | |
12205 | to do is check that the decrypt undoes the encrypt, so far. Send me test | |
12206 | vectors if you have them. | |
12207 | [Ben Laurie] | |
12208 | ||
12209 | *) Correct calculation of key length for export ciphers (too much space was | |
12210 | allocated for null ciphers). This has not been tested! | |
12211 | [Ben Laurie] | |
12212 | ||
12213 | *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage | |
12214 | message is now correct (it understands "crypto" and "ssl" on its | |
12215 | command line). There is also now an "update" option. This will update | |
12216 | the util/ssleay.num and util/libeay.num files with any new functions. | |
12217 | If you do a: | |
12218 | perl util/mkdef.pl crypto ssl update | |
12219 | it will update them. | |
12220 | [Steve Henson] | |
12221 | ||
12222 | *) Overhauled the Perl interface (perl/*): | |
12223 | - ported BN stuff to OpenSSL's different BN library | |
12224 | - made the perl/ source tree CVS-aware | |
12225 | - renamed the package from SSLeay to OpenSSL (the files still contain | |
12226 | their history because I've copied them in the repository) | |
12227 | - removed obsolete files (the test scripts will be replaced | |
12228 | by better Test::Harness variants in the future) | |
12229 | [Ralf S. Engelschall] | |
12230 | ||
12231 | *) First cut for a very conservative source tree cleanup: | |
12232 | 1. merge various obsolete readme texts into doc/ssleay.txt | |
12233 | where we collect the old documents and readme texts. | |
12234 | 2. remove the first part of files where I'm already sure that we no | |
12235 | longer need them because of three reasons: either they are just temporary | |
12236 | files which were left by Eric or they are preserved original files where | |
12237 | I've verified that the diff is also available in the CVS via "cvs diff | |
12238 | -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for | |
12239 | the crypto/md/ stuff). | |
12240 | [Ralf S. Engelschall] | |
12241 | ||
12242 | *) More extension code. Incomplete support for subject and issuer alt | |
12243 | name, issuer and authority key id. Change the i2v function parameters | |
12244 | and add an extra 'crl' parameter in the X509V3_CTX structure: guess | |
12245 | what that's for :-) Fix to ASN1 macro which messed up | |
12246 | IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED. | |
12247 | [Steve Henson] | |
12248 | ||
12249 | *) Preliminary support for ENUMERATED type. This is largely copied from the | |
12250 | INTEGER code. | |
12251 | [Steve Henson] | |
12252 | ||
12253 | *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy. | |
12254 | [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] | |
12255 | ||
12256 | *) Make sure `make rehash' target really finds the `openssl' program. | |
12257 | [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>] | |
12258 | ||
12259 | *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd | |
12260 | like to hear about it if this slows down other processors. | |
12261 | [Ben Laurie] | |
12262 | ||
12263 | *) Add CygWin32 platform information to Configure script. | |
12264 | [Alan Batie <batie@aahz.jf.intel.com>] | |
12265 | ||
12266 | *) Fixed ms/32all.bat script: `no_asm' -> `no-asm' | |
12267 | [Rainer W. Gerling <gerling@mpg-gv.mpg.de>] | |
12268 | ||
12269 | *) New program nseq to manipulate netscape certificate sequences | |
12270 | [Steve Henson] | |
12271 | ||
12272 | *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a | |
12273 | few typos. | |
12274 | [Steve Henson] | |
12275 | ||
12276 | *) Fixes to BN code. Previously the default was to define BN_RECURSION | |
12277 | but the BN code had some problems that would cause failures when | |
12278 | doing certificate verification and some other functions. | |
12279 | [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] | |
12280 | ||
12281 | *) Add ASN1 and PEM code to support netscape certificate sequences. | |
12282 | [Steve Henson] | |
12283 | ||
12284 | *) Add ASN1 and PEM code to support netscape certificate sequences. | |
12285 | [Steve Henson] | |
12286 | ||
12287 | *) Add several PKIX and private extended key usage OIDs. | |
12288 | [Steve Henson] | |
12289 | ||
12290 | *) Modify the 'ca' program to handle the new extension code. Modify | |
12291 | openssl.cnf for new extension format, add comments. | |
12292 | [Steve Henson] | |
12293 | ||
12294 | *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req' | |
12295 | and add a sample to openssl.cnf so req -x509 now adds appropriate | |
12296 | CA extensions. | |
12297 | [Steve Henson] | |
12298 | ||
12299 | *) Continued X509 V3 changes. Add to other makefiles, integrate with the | |
12300 | error code, add initial support to X509_print() and x509 application. | |
12301 | [Steve Henson] | |
12302 | ||
12303 | *) Takes a deep breath and start adding X509 V3 extension support code. Add | |
12304 | files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this | |
12305 | stuff is currently isolated and isn't even compiled yet. | |
12306 | [Steve Henson] | |
12307 | ||
12308 | *) Continuing patches for GeneralizedTime. Fix up certificate and CRL | |
12309 | ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print. | |
12310 | Removed the versions check from X509 routines when loading extensions: | |
12311 | this allows certain broken certificates that don't set the version | |
12312 | properly to be processed. | |
12313 | [Steve Henson] | |
12314 | ||
12315 | *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another | |
12316 | Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which | |
12317 | can still be regenerated with "make depend". | |
12318 | [Ben Laurie] | |
12319 | ||
12320 | *) Spelling mistake in C version of CAST-128. | |
12321 | [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>] | |
12322 | ||
12323 | *) Changes to the error generation code. The perl script err-code.pl | |
12324 | now reads in the old error codes and retains the old numbers, only | |
12325 | adding new ones if necessary. It also only changes the .err files if new | |
12326 | codes are added. The makefiles have been modified to only insert errors | |
12327 | when needed (to avoid needlessly modifying header files). This is done | |
12328 | by only inserting errors if the .err file is newer than the auto generated | |
12329 | C file. To rebuild all the error codes from scratch (the old behaviour) | |
12330 | either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl | |
12331 | or delete all the .err files. | |
12332 | [Steve Henson] | |
12333 | ||
12334 | *) CAST-128 was incorrectly implemented for short keys. The C version has | |
12335 | been fixed, but is untested. The assembler versions are also fixed, but | |
12336 | new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing | |
12337 | to regenerate it if needed. | |
12338 | [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun | |
12339 | Hagino <itojun@kame.net>] | |
12340 | ||
12341 | *) File was opened incorrectly in randfile.c. | |
12342 | [Ulf Möller <ulf@fitug.de>] | |
12343 | ||
12344 | *) Beginning of support for GeneralizedTime. d2i, i2d, check and print | |
12345 | functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or | |
12346 | GeneralizedTime. ASN1_TIME is the proper type used in certificates et | |
12347 | al: it's just almost always a UTCTime. Note this patch adds new error | |
12348 | codes so do a "make errors" if there are problems. | |
12349 | [Steve Henson] | |
12350 | ||
12351 | *) Correct Linux 1 recognition in config. | |
12352 | [Ulf Möller <ulf@fitug.de>] | |
12353 | ||
12354 | *) Remove pointless MD5 hash when using DSA keys in ca. | |
12355 | [Anonymous <nobody@replay.com>] | |
12356 | ||
12357 | *) Generate an error if given an empty string as a cert directory. Also | |
12358 | generate an error if handed NULL (previously returned 0 to indicate an | |
12359 | error, but didn't set one). | |
12360 | [Ben Laurie, reported by Anonymous <nobody@replay.com>] | |
12361 | ||
12362 | *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last. | |
12363 | [Ben Laurie] | |
12364 | ||
12365 | *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct | |
12366 | parameters. This was causing a warning which killed off the Win32 compile. | |
12367 | [Steve Henson] | |
12368 | ||
12369 | *) Remove C++ style comments from crypto/bn/bn_local.h. | |
12370 | [Neil Costigan <neil.costigan@celocom.com>] | |
12371 | ||
12372 | *) The function OBJ_txt2nid was broken. It was supposed to return a nid | |
12373 | based on a text string, looking up short and long names and finally | |
12374 | "dot" format. The "dot" format stuff didn't work. Added new function | |
12375 | OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote | |
12376 | OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the | |
12377 | OID is not part of the table. | |
12378 | [Steve Henson] | |
12379 | ||
12380 | *) Add prototypes to X509 lookup/verify methods, fixing a bug in | |
12381 | X509_LOOKUP_by_alias(). | |
12382 | [Ben Laurie] | |
12383 | ||
12384 | *) Sort openssl functions by name. | |
12385 | [Ben Laurie] | |
12386 | ||
12387 | *) Get the gendsa program working (hopefully) and add it to app list. Remove | |
12388 | encryption from sample DSA keys (in case anyone is interested the password | |
12389 | was "1234"). | |
12390 | [Steve Henson] | |
12391 | ||
12392 | *) Make _all_ *_free functions accept a NULL pointer. | |
12393 | [Frans Heymans <fheymans@isaserver.be>] | |
12394 | ||
12395 | *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use | |
12396 | NULL pointers. | |
12397 | [Anonymous <nobody@replay.com>] | |
12398 | ||
12399 | *) s_server should send the CAfile as acceptable CAs, not its own cert. | |
12400 | [Bodo Moeller <3moeller@informatik.uni-hamburg.de>] | |
12401 | ||
12402 | *) Don't blow it for numeric -newkey arguments to apps/req. | |
12403 | [Bodo Moeller <3moeller@informatik.uni-hamburg.de>] | |
12404 | ||
12405 | *) Temp key "for export" tests were wrong in s3_srvr.c. | |
12406 | [Anonymous <nobody@replay.com>] | |
12407 | ||
12408 | *) Add prototype for temp key callback functions | |
12409 | SSL_CTX_set_tmp_{rsa,dh}_callback(). | |
12410 | [Ben Laurie] | |
12411 | ||
12412 | *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and | |
12413 | DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey(). | |
12414 | [Steve Henson] | |
12415 | ||
12416 | *) X509_name_add_entry() freed the wrong thing after an error. | |
12417 | [Arne Ansper <arne@ats.cyber.ee>] | |
12418 | ||
12419 | *) rsa_eay.c would attempt to free a NULL context. | |
12420 | [Arne Ansper <arne@ats.cyber.ee>] | |
12421 | ||
12422 | *) BIO_s_socket() had a broken should_retry() on Windoze. | |
12423 | [Arne Ansper <arne@ats.cyber.ee>] | |
12424 | ||
12425 | *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH. | |
12426 | [Arne Ansper <arne@ats.cyber.ee>] | |
12427 | ||
12428 | *) Make sure the already existing X509_STORE->depth variable is initialized | |
12429 | in X509_STORE_new(), but document the fact that this variable is still | |
12430 | unused in the certificate verification process. | |
12431 | [Ralf S. Engelschall] | |
12432 | ||
12433 | *) Fix the various library and apps files to free up pkeys obtained from | |
12434 | X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions. | |
12435 | [Steve Henson] | |
12436 | ||
12437 | *) Fix reference counting in X509_PUBKEY_get(). This makes | |
12438 | demos/maurice/example2.c work, amongst others, probably. | |
12439 | [Steve Henson and Ben Laurie] | |
12440 | ||
12441 | *) First cut of a cleanup for apps/. First the `ssleay' program is now named | |
12442 | `openssl' and second, the shortcut symlinks for the `openssl <command>' | |
12443 | are no longer created. This way we have a single and consistent command | |
12444 | line interface `openssl <command>', similar to `cvs <command>'. | |
12445 | [Ralf S. Engelschall, Paul Sutton and Ben Laurie] | |
12446 | ||
12447 | *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey | |
12448 | BIT STRING wrapper always have zero unused bits. | |
12449 | [Steve Henson] | |
12450 | ||
12451 | *) Add CA.pl, perl version of CA.sh, add extended key usage OID. | |
12452 | [Steve Henson] | |
12453 | ||
12454 | *) Make the top-level INSTALL documentation easier to understand. | |
12455 | [Paul Sutton] | |
12456 | ||
12457 | *) Makefiles updated to exit if an error occurs in a sub-directory | |
12458 | make (including if user presses ^C) [Paul Sutton] | |
12459 | ||
12460 | *) Make Montgomery context stuff explicit in RSA data structure. | |
12461 | [Ben Laurie] | |
12462 | ||
12463 | *) Fix build order of pem and err to allow for generated pem.h. | |
12464 | [Ben Laurie] | |
12465 | ||
12466 | *) Fix renumbering bug in X509_NAME_delete_entry(). | |
12467 | [Ben Laurie] | |
12468 | ||
12469 | *) Enhanced the err-ins.pl script so it makes the error library number | |
12470 | global and can add a library name. This is needed for external ASN1 and | |
12471 | other error libraries. | |
12472 | [Steve Henson] | |
12473 | ||
12474 | *) Fixed sk_insert which never worked properly. | |
12475 | [Steve Henson] | |
12476 | ||
12477 | *) Fix ASN1 macros so they can handle indefinite length constructed | |
12478 | EXPLICIT tags. Some non standard certificates use these: they can now | |
12479 | be read in. | |
12480 | [Steve Henson] | |
12481 | ||
12482 | *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc) | |
12483 | into a single doc/ssleay.txt bundle. This way the information is still | |
12484 | preserved but no longer messes up this directory. Now it's new room for | |
12485 | the new set of documentation files. | |
12486 | [Ralf S. Engelschall] | |
12487 | ||
12488 | *) SETs were incorrectly DER encoded. This was a major pain, because they | |
12489 | shared code with SEQUENCEs, which aren't coded the same. This means that | |
12490 | almost everything to do with SETs or SEQUENCEs has either changed name or | |
12491 | number of arguments. | |
12492 | [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>] | |
12493 | ||
12494 | *) Fix test data to work with the above. | |
12495 | [Ben Laurie] | |
12496 | ||
12497 | *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but | |
12498 | was already fixed by Eric for 0.9.1 it seems. | |
12499 | [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>] | |
12500 | ||
12501 | *) Autodetect FreeBSD3. | |
12502 | [Ben Laurie] | |
12503 | ||
12504 | *) Fix various bugs in Configure. This affects the following platforms: | |
12505 | nextstep | |
12506 | ncr-scde | |
12507 | unixware-2.0 | |
12508 | unixware-2.0-pentium | |
12509 | sco5-cc. | |
12510 | [Ben Laurie] | |
12511 | ||
12512 | *) Eliminate generated files from CVS. Reorder tests to regenerate files | |
12513 | before they are needed. | |
12514 | [Ben Laurie] | |
12515 | ||
12516 | *) Generate Makefile.ssl from Makefile.org (to keep CVS happy). | |
12517 | [Ben Laurie] | |
12518 | ||
12519 | ||
12520 | Changes between 0.9.1b and 0.9.1c [23-Dec-1998] | |
12521 | ||
12522 | *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and | |
12523 | changed SSLeay to OpenSSL in version strings. | |
12524 | [Ralf S. Engelschall] | |
12525 | ||
12526 | *) Some fixups to the top-level documents. | |
12527 | [Paul Sutton] | |
12528 | ||
12529 | *) Fixed the nasty bug where rsaref.h was not found under compile-time | |
12530 | because the symlink to include/ was missing. | |
12531 | [Ralf S. Engelschall] | |
12532 | ||
12533 | *) Incorporated the popular no-RSA/DSA-only patches | |
12534 | which allow to compile a RSA-free SSLeay. | |
12535 | [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall] | |
12536 | ||
12537 | *) Fixed nasty rehash problem under `make -f Makefile.ssl links' | |
12538 | when "ssleay" is still not found. | |
12539 | [Ralf S. Engelschall] | |
12540 | ||
12541 | *) Added more platforms to Configure: Cray T3E, HPUX 11, | |
12542 | [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>] | |
12543 | ||
12544 | *) Updated the README file. | |
12545 | [Ralf S. Engelschall] | |
12546 | ||
12547 | *) Added various .cvsignore files in the CVS repository subdirs | |
12548 | to make a "cvs update" really silent. | |
12549 | [Ralf S. Engelschall] | |
12550 | ||
12551 | *) Recompiled the error-definition header files and added | |
12552 | missing symbols to the Win32 linker tables. | |
12553 | [Ralf S. Engelschall] | |
12554 | ||
12555 | *) Cleaned up the top-level documents; | |
12556 | o new files: CHANGES and LICENSE | |
12557 | o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay | |
12558 | o merged COPYRIGHT into LICENSE | |
12559 | o removed obsolete TODO file | |
12560 | o renamed MICROSOFT to INSTALL.W32 | |
12561 | [Ralf S. Engelschall] | |
12562 | ||
12563 | *) Removed dummy files from the 0.9.1b source tree: | |
12564 | crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi | |
12565 | crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f | |
12566 | crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f | |

12568 | util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f | |
12569 | [Ralf S. Engelschall] | |
12570 | ||
12571 | *) Added various platform portability fixes. | |
12572 | [Mark J. Cox] | |
12573 | ||
12574 | *) The Genesis of the OpenSSL rpject: | |
12575 | We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A. | |
12576 | Young and Tim J. Hudson created while they were working for C2Net until | |
12577 | summer 1998. | |
12578 | [The OpenSSL Project] | |
12579 | ||
12580 | ||
12581 | Changes between 0.9.0b and 0.9.1b [not released] | |
12582 | ||
12583 | *) Updated a few CA certificates under certs/ | |
12584 | [Eric A. Young] | |
12585 | ||
12586 | *) Changed some BIGNUM api stuff. | |
12587 | [Eric A. Young] | |
12588 | ||
12589 | *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD, | |
12590 | DGUX x86, Linux Alpha, etc. | |
12591 | [Eric A. Young] | |
12592 | ||
12593 | *) New COMP library [crypto/comp/] for SSL Record Layer Compression: | |
12594 | RLE (dummy implemented) and ZLIB (really implemented when ZLIB is | |
12595 | available). | |
12596 | [Eric A. Young] | |
12597 | ||
12598 | *) Add -strparse option to asn1pars program which parses nested | |
12599 | binary structures | |
12600 | [Dr Stephen Henson <shenson@bigfoot.com>] | |
12601 | ||
12602 | *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs. | |
12603 | [Eric A. Young] | |
12604 | ||
12605 | *) DSA fix for "ca" program. | |
12606 | [Eric A. Young] | |
12607 | ||
12608 | *) Added "-genkey" option to "dsaparam" program. | |
12609 | [Eric A. Young] | |
12610 | ||
12611 | *) Added RIPE MD160 (rmd160) message digest. | |
12612 | [Eric A. Young] | |
12613 | ||
12614 | *) Added -a (all) option to "ssleay version" command. | |
12615 | [Eric A. Young] | |
12616 | ||
12617 | *) Added PLATFORM define which is the id given to Configure. | |
12618 | [Eric A. Young] | |
12619 | ||
12620 | *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking. | |
12621 | [Eric A. Young] | |
12622 | ||
12623 | *) Extended the ASN.1 parser routines. | |
12624 | [Eric A. Young] | |
12625 | ||
12626 | *) Extended BIO routines to support REUSEADDR, seek, tell, etc. | |
12627 | [Eric A. Young] | |
12628 | ||
12629 | *) Added a BN_CTX to the BN library. | |
12630 | [Eric A. Young] | |
12631 | ||
12632 | *) Fixed the weak key values in DES library | |
12633 | [Eric A. Young] | |
12634 | ||
12635 | *) Changed API in EVP library for cipher aliases. | |
12636 | [Eric A. Young] | |
12637 | ||
12638 | *) Added support for RC2/64bit cipher. | |
12639 | [Eric A. Young] | |
12640 | ||
12641 | *) Converted the lhash library to the crypto/mem.c functions. | |
12642 | [Eric A. Young] | |
12643 | ||
12644 | *) Added more recognized ASN.1 object ids. | |
12645 | [Eric A. Young] | |
12646 | ||
12647 | *) Added more RSA padding checks for SSL/TLS. | |
12648 | [Eric A. Young] | |
12649 | ||
12650 | *) Added BIO proxy/filter functionality. | |
12651 | [Eric A. Young] | |
12652 | ||
12653 | *) Added extra_certs to SSL_CTX which can be used | |
12654 | send extra CA certificates to the client in the CA cert chain sending | |
12655 | process. It can be configured with SSL_CTX_add_extra_chain_cert(). | |
12656 | [Eric A. Young] | |
12657 | ||
12658 | *) Now Fortezza is denied in the authentication phase because | |
12659 | this is key exchange mechanism is not supported by SSLeay at all. | |
12660 | [Eric A. Young] | |
12661 | ||
12662 | *) Additional PKCS1 checks. | |
12663 | [Eric A. Young] | |
12664 | ||
12665 | *) Support the string "TLSv1" for all TLS v1 ciphers. | |
12666 | [Eric A. Young] | |
12667 | ||
12668 | *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the | |
12669 | ex_data index of the SSL context in the X509_STORE_CTX ex_data. | |
12670 | [Eric A. Young] | |
12671 | ||
12672 | *) Fixed a few memory leaks. | |
12673 | [Eric A. Young] | |
12674 | ||
12675 | *) Fixed various code and comment typos. | |
12676 | [Eric A. Young] | |
12677 | ||
12678 | *) A minor bug in ssl/s3_clnt.c where there would always be 4 0 | |
12679 | bytes sent in the client random. | |
12680 | [Edward Bishop <ebishop@spyglass.com>] | |
12681 |
