Statement

This security flaw can only be exploited when a malicious client negotiates SSLv2 ciphers and completes a SSLv2 handshake. This flaw cannot be actively exploited by a Man-In-The-Middle attacker.

All versions of OpenSSL shipped with Red Hat Enterprise Linux enable SSLv2 protocol, but disable SSLv2 ciphers by default (in Red Hat Enterprise Linux 6 and later), therefore are vulnerable to this flaw. Red Hat Product Security has rated this issue as having Low security impact, a future update may address this flaw.

SSLv2 suffers from a number of security flaws allowing attackers to capture and alter information passed between a client and the server. Therefore we strongly recommend that SSLv2 should be disabled on all the SSL/TLS servers.
