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].
