It was discovered that OpenSSL incorrectly handled memory when verifying
the integrity of a session ticket. A remote attacker could possibly use
this issue to cause OpenSSL to consume resources, resulting in a denial of
service. (CVE-2014-3567)
In addition, this update introduces support for the TLS Fallback Signaling

downgrade attacks when certain applications such as web browsers attempt
to reconnect using a lower protocol version for interoperability reasons.");
