OpenSSL before 1.0.2f would allow for a process to re-use the same private
Diffie-Hellman exponent repeatedly during its entire lifetime, which, given
that it also allows to use custom DH parameters which may be based on
unsafe primes, could enable an attack that could discover the DH exponent,
compromising the security of DH symmetric key negotiation (CVE-2016-0701).

In OpenSSL before 1.0.2f, A malicious client can negotiate SSLv2 ciphers
that have been disabled on the server and complete SSLv2 handshakes even if
all SSLv2 ciphers have been disabled, provided that the SSLv2 protocol was
not also disabled via SSL_OP_NO_SSLv2 (CVE-2015-3197).");
