- Changes between 1.0.2o and 1.0.2p [xx XXX xxxx]
+ Changes between 1.0.2p and 1.0.2q [xx XXX xxxx]
+
+  *) Resolve a compatibility issue in EC_GROUP handling with the FIPS Object
+     Module, accidentally introduced while backporting security fixes from the
+     development branch and hindering the use of ECC in FIPS mode.
+     [Nicola Tuveri]
+
+ Changes between 1.0.2o and 1.0.2p [14 Aug 2018]
+
+  *) Client DoS due to large DH parameter
+
+     During key agreement in a TLS handshake using a DH(E) based ciphersuite a
+     malicious server can send a very large prime value to the client. This will
+     cause the client to spend an unreasonably long period of time generating a
+     key for this prime resulting in a hang until the client has finished. This
+     could be exploited in a Denial Of Service attack.
+
+     This issue was reported to OpenSSL on 5th June 2018 by Guido Vranken
+     (CVE-2018-0732)
+     [Guido Vranken]
+
+  *) Cache timing vulnerability in RSA Key Generation
+
+     The OpenSSL RSA Key generation algorithm has been shown to be vulnerable to
+     a cache timing side channel attack. An attacker with sufficient access to
+     mount cache timing attacks during the RSA key generation process could
+     recover the private key.
+
+     This issue was reported to OpenSSL on 4th April 2018 by Alejandro Cabrera
+     Aldaya, Billy Brumley, Cesar Pereida Garcia and Luis Manuel Alvarez Tapia.
+     (CVE-2018-0737)
+     [Billy Brumley]
+
+  *) Make EVP_PKEY_asn1_new() a bit stricter about its input.  A NULL pem_str
+     parameter is no longer accepted, as it leads to a corrupt table.  NULL
+     pem_str is reserved for alias entries only.
+     [Richard Levitte]
+
+  *) Revert blinding in ECDSA sign and instead make problematic addition
+     length-invariant. Switch even to fixed-length Montgomery multiplication.
+     [Andy Polyakov]
+
+  *) Change generating and checking of primes so that the error rate of not
+     being prime depends on the intended use based on the size of the input.
+     For larger primes this will result in more rounds of Miller-Rabin.
+     The maximal error rate for primes with more than 1080 bits is lowered
+     to 2^-128.
+     [Kurt Roeckx, Annie Yousar]
 
   *) Increase the number of Miller-Rabin rounds for DSA key generating to 64.
