0b9e8276 | 5 | Changes between 1.0.1k and 1.0.2 [xx XXX xxxx] |
0a9f7780 | 6 | |
84d4f99d MC |
7 | *) SRTP Memory Leak. |
8 | ||
9 | A flaw in the DTLS SRTP extension parsing code allows an attacker, who | |
10 | sends a carefully crafted handshake message, to cause OpenSSL to fail | |
11 | to free up to 64k of memory causing a memory leak. This could be | |
12 | exploited in a Denial Of Service attack. This issue affects OpenSSL | |
13 | 1.0.1 server implementations for both SSL/TLS and DTLS regardless of | |
14 | whether SRTP is used or configured. Implementations of OpenSSL that | |
15 | have been compiled with OPENSSL_NO_SRTP defined are not affected. | |
16 | ||
17 | The fix was developed by the OpenSSL team. | |
18 | (CVE-2014-3513) | |
19 | [OpenSSL team] | |
20 | ||
21 | *) Session Ticket Memory Leak. | |
22 | ||
23 | When an OpenSSL SSL/TLS/DTLS server receives a session ticket the | |
24 | integrity of that ticket is first verified. In the event of a session | |
25 | ticket integrity check failing, OpenSSL will fail to free memory | |
26 | causing a memory leak. By sending a large number of invalid session | |
27 | tickets an attacker could exploit this issue in a Denial Of Service | |
28 | attack. | |
29 | (CVE-2014-3567) | |
30 | [Steve Henson] | |
31 | ||
32 | *) Build option no-ssl3 is incomplete. | |
33 | ||
34 | When OpenSSL is configured with "no-ssl3" as a build option, servers | |
35 | could accept and complete a SSL 3.0 handshake, and clients could be | |
36 | configured to send them. | |
37 | (CVE-2014-3568) | |
38 | [Akamai and the OpenSSL team] | |
39 | ||
a46c7052 BM |
40 | *) Add support for TLS_FALLBACK_SCSV. |
41 | Client applications doing fallback retries should call | |
42 | SSL_set_mode(s, SSL_MODE_SEND_FALLBACK_SCSV). | |
43 | (CVE-2014-3566) | |
44 | [Adam Langley, Bodo Moeller] | |
45 | ||
1cfd7cf3 AP |
46 | *) Facilitate "universal" ARM builds targeting range of ARM ISAs, e.g. |
47 | ARMv5 through ARMv8, as opposite to "locking" it to single one. | |
48 | So far those who have to target multiple plaforms would compromise | |
49 | and argue that binary targeting say ARMv5 would still execute on | |
50 | ARMv8. "Universal" build resolves this compromise by providing | |
51 | near-optimal performance even on newer platforms. | |
52 | [Andy Polyakov] | |
53 | ||
d2a1226b AP |
54 | *) Accelerated NIST P-256 elliptic curve implementation for x86_64 |
55 | (other platforms pending). | |
0ce2dbfb | 56 | [Shay Gueron & Vlad Krasnov (Intel Corp), Andy Polyakov] |
d2a1226b | 57 | |
2102c53c DSH |
58 | *) Add support for the SignedCertificateTimestampList certificate and |
59 | OCSP response extensions from RFC6962. | |
60 | [Rob Stradling] | |
61 | ||
d5213519 BM |
62 | *) Fix ec_GFp_simple_points_make_affine (thus, EC_POINTs_mul etc.) |
63 | for corner cases. (Certain input points at infinity could lead to | |
64 | bogus results, with non-infinity inputs mapped to infinity too.) | |
65 | [Bodo Moeller] | |
66 | ||
0ae6ba18 AP |
67 | *) Initial support for PowerISA 2.0.7, first implemented in POWER8. |
68 | This covers AES, SHA256/512 and GHASH. "Initial" means that most | |
69 | common cases are optimized and there still is room for further | |
70 | improvements. Vector Permutation AES for Altivec is also added. | |
71 | [Andy Polyakov] | |
72 | ||
73 | *) Add support for little-endian ppc64 Linux target. | |
74 | [Marcelo Cerri (IBM)] | |
75 | ||
76 | *) Initial support for AMRv8 ISA crypto extensions. This covers AES, | |
77 | SHA1, SHA256 and GHASH. "Initial" means that most common cases | |
78 | are optimized and there still is room for further improvements. | |
79 | Both 32- and 64-bit modes are supported. | |
80 | [Andy Polyakov, Ard Biesheuvel (Linaro)] | |
81 | ||
82 | *) Improved ARMv7 NEON support. | |
83 | [Andy Polyakov] | |
84 | ||
85 | *) Support for SPARC Architecture 2011 crypto extensions, first | |
86 | implemented in SPARC T4. This covers AES, DES, Camellia, SHA1, | |
87 | SHA256/512, MD5, GHASH and modular exponentiation. | |
88 | [Andy Polyakov, David Miller] | |
89 | ||
90 | *) Accelerated modular exponentiation for Intel processors, a.k.a. | |
91 | RSAZ. | |
0ce2dbfb | 92 | [Shay Gueron & Vlad Krasnov (Intel Corp)] |
0ae6ba18 AP |
93 | |
94 | *) Support for new and upcoming Intel processors, including AVX2, | |
95 | BMI and SHA ISA extensions. This includes additional "stitched" | |
96 | implementations, AESNI-SHA256 and GCM, and multi-buffer support | |
97 | for TLS encrypt. | |
98 | ||
99 | This work was sponsored by Intel Corp. | |
100 | [Andy Polyakov] | |
101 | ||
c578fe37 BM |
102 | *) Support for DTLS 1.2. This adds two sets of DTLS methods: DTLS_*_method() |
103 | supports both DTLS 1.2 and 1.0 and should use whatever version the peer | |
104 | supports and DTLSv1_2_*_method() which supports DTLS 1.2 only. | |
105 | [Steve Henson] | |
106 | ||
b9fa413a DSH |
107 | *) Use algorithm specific chains in SSL_CTX_use_certificate_chain_file(): |
108 | this fixes a limiation in previous versions of OpenSSL. | |
109 | [Steve Henson] | |
110 | ||
25f93585 DSH |
111 | *) Extended RSA OAEP support via EVP_PKEY API. Options to specify digest, |
112 | MGF1 digest and OAEP label. | |
113 | [Steve Henson] | |
114 | ||
c6f33865 DSH |
115 | *) Add EVP support for key wrapping algorithms, to avoid problems with |
116 | existing code the flag EVP_CIPHER_CTX_WRAP_ALLOW has to be set in | |
117 | the EVP_CIPHER_CTX or an error is returned. Add AES and DES3 wrap | |
118 | algorithms and include tests cases. | |
119 | [Steve Henson] | |
120 | ||
7c23127f DSH |
121 | *) Add functions to allocate and set the fields of an ECDSA_METHOD |
122 | structure. | |
123 | [Douglas E. Engert, Steve Henson] | |
124 | ||
904348a4 DSH |
125 | *) New functions OPENSSL_gmtime_diff and ASN1_TIME_diff to find the |
126 | difference in days and seconds between two tm or ASN1_TIME structures. | |
127 | [Steve Henson] | |
128 | ||
171c4da5 DSH |
129 | *) Add -rev test option to s_server to just reverse order of characters |
130 | received by client and send back to server. Also prints an abbreviated | |
131 | summary of the connection parameters. | |
132 | [Steve Henson] | |
133 | ||
04611fb0 DSH |
134 | *) New option -brief for s_client and s_server to print out a brief summary |
135 | of connection parameters. | |
136 | [Steve Henson] | |
137 | ||
e27711cf T |
138 | *) Add callbacks for arbitrary TLS extensions. |
139 | [Trevor Perrin <trevp@trevp.net> and Ben Laurie] | |
140 | ||
57912ed3 DSH |
141 | *) New option -crl_download in several openssl utilities to download CRLs |
142 | from CRLDP extension in certificates. | |
143 | [Steve Henson] | |
144 | ||
e318431e DSH |
145 | *) New options -CRL and -CRLform for s_client and s_server for CRLs. |
146 | [Steve Henson] | |
147 | ||
6a10f38d DSH |
148 | *) New function X509_CRL_diff to generate a delta CRL from the difference |
149 | of two full CRLs. Add support to "crl" utility. | |
150 | [Steve Henson] | |
151 | ||
75f53531 DSH |
152 | *) New functions to set lookup_crls function and to retrieve |
153 | X509_STORE from X509_STORE_CTX. | |
154 | [Steve Henson] | |
155 | ||
2aa3ef78 DSH |
156 | *) Print out deprecated issuer and subject unique ID fields in |
157 | certificates. | |
158 | [Steve Henson] | |
159 | ||
5c8d41be DSH |
160 | *) Extend OCSP I/O functions so they can be used for simple general purpose |
161 | HTTP as well as OCSP. New wrapper function which can be used to download | |
162 | CRLs using the OCSP API. | |
163 | [Steve Henson] | |
164 | ||
15387e4c DSH |
165 | *) Delegate command line handling in s_client/s_server to SSL_CONF APIs. |
166 | [Steve Henson] | |
167 | ||
49ef33fa DSH |
168 | *) SSL_CONF* functions. These provide a common framework for application |
169 | configuration using configuration files or command lines. | |
170 | [Steve Henson] | |
171 | ||
bc200e69 DSH |
172 | *) SSL/TLS tracing code. This parses out SSL/TLS records using the |
173 | message callback and prints the results. Needs compile time option | |
174 | "enable-ssl-trace". New options to s_client and s_server to enable | |
175 | tracing. | |
176 | [Steve Henson] | |
177 | ||
78b5d89d | 178 | *) New ctrl and macro to retrieve supported points extensions. |
1b9a59c3 | 179 | Print out extension in s_server and s_client. |
78b5d89d DSH |
180 | [Steve Henson] |
181 | ||
bd9fc1d6 DSH |
182 | *) New functions to retrieve certificate signature and signature |
183 | OID NID. | |
184 | [Steve Henson] | |
185 | ||
1520e6c0 DSH |
186 | *) Add functions to retrieve and manipulate the raw cipherlist sent by a |
187 | client to OpenSSL. | |
188 | [Steve Henson] | |
189 | ||
ccf6a19e DSH |
190 | *) New Suite B modes for TLS code. These use and enforce the requirements |
191 | of RFC6460: restrict ciphersuites, only permit Suite B algorithms and | |
192 | only use Suite B curves. The Suite B modes can be set by using the | |
193 | strings "SUITEB128", "SUITEB192" or "SUITEB128ONLY" for the cipherstring. | |
194 | [Steve Henson] | |
195 | ||
ba8bdea7 DSH |
196 | *) New chain verification flags for Suite B levels of security. Check |
197 | algorithms are acceptable when flags are set in X509_verify_cert. | |
198 | [Steve Henson] | |
199 | ||
6660baee DSH |
200 | *) Make tls1_check_chain return a set of flags indicating checks passed |
201 | by a certificate chain. Add additional tests to handle client | |
202 | certificates: checks for matching certificate type and issuer name | |
203 | comparison. | |
204 | [Steve Henson] | |
205 | ||
25d4c925 DSH |
206 | *) If an attempt is made to use a signature algorithm not in the peer |
207 | preference list abort the handshake. If client has no suitable | |
208 | signature algorithms in response to a certificate request do not | |
209 | use the certificate. | |
210 | [Steve Henson] | |
211 | ||
44adfeb6 DSH |
212 | *) If server EC tmp key is not in client preference list abort handshake. |
213 | [Steve Henson] | |
214 | ||
b762acad DSH |
215 | *) Add support for certificate stores in CERT structure. This makes it |
216 | possible to have different stores per SSL structure or one store in | |
217 | the parent SSL_CTX. Include distint stores for certificate chain | |
218 | verification and chain building. New ctrl SSL_CTRL_BUILD_CERT_CHAIN | |
219 | to build and store a certificate chain in CERT structure: returing | |
220 | an error if the chain cannot be built: this will allow applications | |
221 | to test if a chain is correctly configured. | |
222 | ||
223 | Note: if the CERT based stores are not set then the parent SSL_CTX | |
224 | store is used to retain compatibility with existing behaviour. | |
225 | ||
226 | [Steve Henson] | |
227 | ||
b28fbdfa DSH |
228 | *) New function ssl_set_client_disabled to set a ciphersuite disabled |
229 | mask based on the current session, check mask when sending client | |
230 | hello and checking the requested ciphersuite. | |
231 | [Steve Henson] | |
232 | ||
a897502c DSH |
233 | *) New ctrls to retrieve and set certificate types in a certificate |
234 | request message. Print out received values in s_client. If certificate | |
235 | types is not set with custom values set sensible values based on | |
236 | supported signature algorithms. | |
237 | [Steve Henson] | |
238 | ||
04c32cdd DSH |
239 | *) Support for distinct client and server supported signature algorithms. |
240 | [Steve Henson] | |
241 | ||
623a5e24 DSH |
242 | *) Add certificate callback. If set this is called whenever a certificate |
243 | is required by client or server. An application can decide which | |
244 | certificate chain to present based on arbitrary criteria: for example | |
245 | supported signature algorithms. Add very simple example to s_server. | |
246 | This fixes many of the problems and restrictions of the existing client | |
247 | certificate callback: for example you can now clear an existing | |
248 | certificate and specify the whole chain. | |
249 | [Steve Henson] | |
250 | ||
484f8762 DSH |
251 | *) Add new "valid_flags" field to CERT_PKEY structure which determines what |
252 | the certificate can be used for (if anything). Set valid_flags field | |
253 | in new tls1_check_chain function. Simplify ssl_set_cert_masks which used | |
254 | to have similar checks in it. | |
255 | ||
256 | Add new "cert_flags" field to CERT structure and include a "strict mode". | |
257 | This enforces some TLS certificate requirements (such as only permitting | |
258 | certificate signature algorithms contained in the supported algorithms | |
259 | extension) which some implementations ignore: this option should be used | |
260 | with caution as it could cause interoperability issues. | |
261 | [Steve Henson] | |
262 | ||
c70a1fee DSH |
263 | *) Update and tidy signature algorithm extension processing. Work out |
264 | shared signature algorithms based on preferences and peer algorithms | |
265 | and print them out in s_client and s_server. Abort handshake if no | |
266 | shared signature algorithms. | |
267 | [Steve Henson] | |
268 | ||
0b362de5 DSH |
269 | *) Add new functions to allow customised supported signature algorithms |
270 | for SSL and SSL_CTX structures. Add options to s_client and s_server | |
271 | to support them. | |
272 | [Steve Henson] | |
273 | ||
d312f7be DSH |
274 | *) New function SSL_certs_clear() to delete all references to certificates |
275 | from an SSL structure. Before this once a certificate had been added | |
276 | it couldn't be removed. | |
277 | [Steve Henson] | |
278 | ||
70cd3c6b DSH |
279 | *) Integrate hostname, email address and IP address checking with certificate |
280 | verification. New verify options supporting checking in opensl utility. | |
281 | [Steve Henson] | |
282 | ||
45da1efc DSH |
283 | *) Fixes and wildcard matching support to hostname and email checking |
284 | functions. Add manual page. | |
285 | [Florian Weimer (Red Hat Product Security Team)] | |
286 | ||
287 | *) New functions to check a hostname email or IP address against a | |
288 | certificate. Add options x509 utility to print results of checks against | |
289 | a certificate. | |
290 | [Steve Henson] | |
291 | ||
d65b8b21 BL |
292 | *) Fix OCSP checking. |
293 | [Rob Stradling <rob.stradling@comodo.com> and Ben Laurie] | |
294 | ||
8c149cfd BM |
295 | *) Initial experimental support for explicitly trusted non-root CAs. |
296 | OpenSSL still tries to build a complete chain to a root but if an | |
297 | intermediate CA has a trust setting included that is used. The first | |
298 | setting is used: whether to trust (e.g., -addtrust option to the x509 | |
299 | utility) or reject. | |
300 | [Steve Henson] | |
d65b8b21 | 301 | |
9d2006d8 DSH |
302 | *) Add -trusted_first option which attempts to find certificates in the |
303 | trusted store even if an untrusted chain is also supplied. | |
304 | [Steve Henson] | |
305 | ||
988037fe AP |
306 | *) MIPS assembly pack updates: support for MIPS32r2 and SmartMIPS ASE, |
307 | platform support for Linux and Android. | |
308 | [Andy Polyakov] | |
309 | ||
0e05b51f AP |
310 | *) Support for linux-x32, ILP32 environment in x86_64 framework. |
311 | [Andy Polyakov] | |
312 | ||
1dded7f7 DSH |
313 | *) Experimental multi-implementation support for FIPS capable OpenSSL. |
314 | When in FIPS mode the approved implementations are used as normal, | |
315 | when not in FIPS mode the internal unapproved versions are used instead. | |
316 | This means that the FIPS capable OpenSSL isn't forced to use the | |
317 | (often lower perfomance) FIPS implementations outside FIPS mode. | |
318 | [Steve Henson] | |
319 | ||
c3cb0691 DSH |
320 | *) Transparently support X9.42 DH parameters when calling |
321 | PEM_read_bio_DHparameters. This means existing applications can handle | |
322 | the new parameter format automatically. | |
323 | [Steve Henson] | |
324 | ||
491734eb DSH |
325 | *) Initial experimental support for X9.42 DH parameter format: mainly |
326 | to support use of 'q' parameter for RFC5114 parameters. | |
327 | [Steve Henson] | |
328 | ||
e811eff5 DSH |
329 | *) Add DH parameters from RFC5114 including test data to dhtest. |
330 | [Steve Henson] | |
331 | ||
e46c807e DSH |
332 | *) Support for automatic EC temporary key parameter selection. If enabled |
333 | the most preferred EC parameters are automatically used instead of | |
334 | hardcoded fixed parameters. Now a server just has to call: | |
335 | SSL_CTX_set_ecdh_auto(ctx, 1) and the server will automatically | |
336 | support ECDH and use the most appropriate parameters. | |
337 | [Steve Henson] | |
338 | ||
6b870763 DSH |
339 | *) Enhance and tidy EC curve and point format TLS extension code. Use |
340 | static structures instead of allocation if default values are used. | |
341 | New ctrls to set curves we wish to support and to retrieve shared curves. | |
342 | Print out shared curves in s_server. New options to s_server and s_client | |
343 | to set list of supported curves. | |
344 | [Steve Henson] | |
345 | ||
55058181 DSH |
346 | *) New ctrls to retrieve supported signature algorithms and |
347 | supported curve values as an array of NIDs. Extend openssl utility | |
348 | to print out received values. | |
349 | [Steve Henson] | |
350 | ||
a068a1d0 DSH |
351 | *) Add new APIs EC_curve_nist2nid and EC_curve_nid2nist which convert |
352 | between NIDs and the more common NIST names such as "P-256". Enhance | |
353 | ecparam utility and ECC method to recognise the NIST names for curves. | |
354 | [Steve Henson] | |
355 | ||
37b16c84 DSH |
356 | *) Enhance SSL/TLS certificate chain handling to support different |
357 | chains for each certificate instead of one chain in the parent SSL_CTX. | |
358 | [Steve Henson] | |
359 | ||
c523eb98 DSH |
360 | *) Support for fixed DH ciphersuite client authentication: where both |
361 | server and client use DH certificates with common parameters. | |
362 | [Steve Henson] | |
363 | ||
0ffa4997 DSH |
364 | *) Support for fixed DH ciphersuites: those requiring DH server |
365 | certificates. | |
366 | [Steve Henson] | |
b9115239 | 367 | |
e9128d94 EK |
368 | *) New function i2d_re_X509_tbs for re-encoding the TBS portion of |
369 | the certificate. | |
370 | Note: Related 1.0.2-beta specific macros X509_get_cert_info, | |
371 | X509_CINF_set_modified, X509_CINF_get_issuer, X509_CINF_get_extensions and | |
372 | X509_CINF_get_signature were reverted post internal team review. | |
373 | ||
4c75f4e5 EK |
374 | Changes between 1.0.1j and 1.0.1k [xx XXX xxxx] |
375 | ||
4aaf1e49 DSH |
376 | *) Abort handshake if server key exchange message is omitted for ephemeral |
377 | ECDH ciphersuites. | |
378 | ||
a936ba11 DSH |
379 | Thanks to Karthikeyan Bhargavan of the PROSECCO team at INRIA for |
380 | reporting this issue. | |
4aaf1e49 DSH |
381 | (CVE-2014-3572) |
382 | [Steve Henson] | |
383 | ||
4b4c1fcc DSH |
384 | *) Remove non-export ephemeral RSA code on client and server. This code |
385 | violated the TLS standard by allowing the use of temporary RSA keys in | |
386 | non-export ciphersuites and could be used by a server to effectively | |
387 | downgrade the RSA key length used to a value smaller than the server | |
a936ba11 DSH |
388 | certificate. Thanks for Karthikeyan Bhargavan of the PROSECCO team at |
389 | INRIA or reporting this issue. | |
4b4c1fcc DSH |
390 | (CVE-2015-0204) |
391 | [Steve Henson] | |
392 | ||
d9b277e0 AL |
393 | *) Ensure that the session ID context of an SSL is updated when its |
394 | SSL_CTX is updated via SSL_set_SSL_CTX. | |
395 | ||
396 | The session ID context is typically set from the parent SSL_CTX, | |
397 | and can vary with the CTX. | |
398 | [Adam Langley] | |
399 | ||
85cfc188 DSH |
400 | *) Fix various certificate fingerprint issues. |
401 | ||
402 | By using non-DER or invalid encodings outside the signed portion of a | |
403 | certificate the fingerprint can be changed without breaking the signature. | |
404 | Although no details of the signed portion of the certificate can be changed | |
405 | this can cause problems with some applications: e.g. those using the | |
406 | certificate fingerprint for blacklists. | |
407 | ||
408 | 1. Reject signatures with non zero unused bits. | |
409 | ||
410 | If the BIT STRING containing the signature has non zero unused bits reject | |
411 | the signature. All current signature algorithms require zero unused bits. | |
412 | ||
413 | 2. Check certificate algorithm consistency. | |
414 | ||
415 | Check the AlgorithmIdentifier inside TBS matches the one in the | |
416 | certificate signature. NB: this will result in signature failure | |
417 | errors for some broken certificates. | |
418 | ||

425 | ||
426 | This will reject various cases including garbage after signature | |
427 | (thanks to Antti Karjalainen and Tuomo Untinen from the Codenomicon CROSS | |
428 | program for discovering this case) and use of BER or invalid ASN.1 INTEGERs | |

431 | Further analysis was conducted and fixes were developed by Stephen Henson | |
432 | of the OpenSSL core team. | |
