"The OpenSSL Project reports :

A flaw in the DTLS SRTP extension parsing code allows an attacker, who
sends a carefully crafted handshake message, to cause OpenSSL to fail
to free up to 64k of memory causing a memory leak. This could be
exploited in a Denial Of Service attack. This issue affects OpenSSL
1.0.1 server implementations for both SSL/TLS and DTLS regardless of
whether SRTP is used or configured. Implementations of OpenSSL that
have been compiled with OPENSSL_NO_SRTP defined are not affected.
[CVE-2014-3513].

When an OpenSSL SSL/TLS/DTLS server receives a session ticket the
integrity of that ticket is first verified. In the event of a session
ticket integrity check failing, OpenSSL will fail to free memory
causing a memory leak. By sending a large number of invalid session
tickets an attacker could exploit this issue in a Denial Of Service
attack. [CVE-2014-3567].

OpenSSL has added support for TLS_FALLBACK_SCSV to allow applications
to block the ability for a MITM attacker to force a protocol
downgrade.

Some client applications (such as browsers) will reconnect using a
downgraded protocol to work around interoperability bugs in older
servers. This could be exploited by an active man-in-the-middle to
downgrade connections to SSL 3.0 even if both sides of the connection
support higher protocols. SSL 3.0 contains a number of weaknesses
including POODLE [CVE-2014-3566].

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. [CVE-2014-3568].");
