Anon DH ServerKeyExchange with 0 p parameter (CVE-2015-1794)

Severity: Low

If a client receives a ServerKeyExchange for an anonymous DH ciphersuite with
the value of p set to 0 then a seg fault can occur leading to a possible denial
of service attack.

This issue affects OpenSSL version 1.0.2.

OpenSSL 1.0.2 users should upgrade to 1.0.2e

This issue was reported to OpenSSL on August 3 2015 by Guy Leaver (Cisco). The
fix was developed by Matt Caswell of the OpenSSL development team.
