CVE-2014-3513
A memory leak flaw was found in the way OpenSSL parsed the DTLS Secure
Real-time Transport Protocol (SRTP) extension data. A remote attacker
could send multiple specially crafted handshake messages to exhaust
all available memory of an SSL/TLS or DTLS server.

CVE-2014-3566 ('POODLE')
A flaw was found in the way SSL 3.0 handled padding bytes when
decrypting messages encrypted using block ciphers in cipher block
chaining (CBC) mode. This flaw allows a man-in-the-middle (MITM)
attacker to decrypt a selected byte of a cipher text in as few as 256
tries if they are able to force a victim application to repeatedly send
the same data over newly created SSL 3.0 connections.

This update adds support for Fallback SCSV to mitigate this issue.

CVE-2014-3567
A memory leak flaw was found in the way an OpenSSL handled failed
session ticket integrity checks. A remote attacker could exhaust all
available memory of an SSL/TLS or DTLS server by sending a large number
of invalid session tickets to that server.

CVE-2014-3568
When OpenSSL is configured with 'no-ssl3' as a build option, servers
could accept and complete a SSL 3.0 handshake, and clients could be
configured to send them.");
