DESCRIPTION OF THE VULNERABILITY

Several vulnerabilities were announced in OpenSSL.

The 2_srvr.c file did not enforce that clear-key-length is zero
for non-export ciphers, so an attacker can act as a
Man-in-the-Middle on SSLv2, in order to read or write data in the
session. [severity:2/4; CVE-2016-0703]

The 2_srvr.c file overwrite some byte dur the Bleichenbacher
protection, so an attacker can act as a Man-in-the-Middle on
SSLv2, in order to read or write data in the session.
[severity:2/4; CVE-2016-0704]
