Changes between 1.0.2o and 1.0.2p [xx XXX xxxx]
+ *) 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.
