OpenSSL Security Advisory [15 Oct 2014]
=======================================
SRTP Memory Leak (CVE-2014-3513)
================================
Severity: High
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.
OpenSSL 1.0.1 users should upgrade to 1.0.1j.
This issue was reported to OpenSSL on 26th September 2014, based on an original
issue and patch developed by the LibreSSL project. Further analysis of the issue
was performed by the OpenSSL team.
The fix was developed by the OpenSSL team.
Session Ticket Memory Leak (CVE-2014-3567)
==========================================
Severity: Medium
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.
OpenSSL 1.0.1 users should upgrade to 1.0.1j.
OpenSSL 1.0.0 users should upgrade to 1.0.0o.
OpenSSL 0.9.8 users should upgrade to 0.9.8zc.
This issue was reported to OpenSSL on 8th October 2014.
The fix was developed by Stephen Henson of the OpenSSL core team.
SSL 3.0 Fallback protection
===========================
Severity: Medium
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).
OpenSSL 1.0.1 users should upgrade to 1.0.1j.
OpenSSL 1.0.0 users should upgrade to 1.0.0o.
OpenSSL 0.9.8 users should upgrade to 0.9.8zc.

Support for TLS_FALLBACK_SCSV was developed by Adam Langley and Bodo Moeller.
Build option no-ssl3 is incomplete (CVE-2014-3568)
==================================================
Severity: Low
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.
OpenSSL 1.0.1 users should upgrade to 1.0.1j.
OpenSSL 1.0.0 users should upgrade to 1.0.0o.
OpenSSL 0.9.8 users should upgrade to 0.9.8zc.
This issue was reported to OpenSSL by Akamai Technologies on 14th October 2014.
The fix was developed by Akamai and the OpenSSL team.

Invalid TLS/DTLS record attack (CVE-2012-2333)
===============================================
A flaw in the OpenSSL handling of CBC mode ciphersuites in TLS 1.1, 1.2 and
DTLS can be exploited in a denial of service attack on both clients and
servers.
DTLS applications are affected in all versions of OpenSSL. TLS is only
affected in OpenSSL 1.0.1 and later.
Thanks to Codenomicon for discovering this issue using Fuzz-o-Matic fuzzing
as a service testing platform.
The fix was developed by Stephen Henson of the OpenSSL core team.
Affected users should upgrade to OpenSSL 1.0.1c, 1.0.0j or 0.9.8x

SN1 BIO incomplete fix (CVE-2012-2131)
=======================================
It was discovered that the fix for CVE-2012-2110 released on 19 Apr
2012 was not sufficient to correct the issue for OpenSSL 0.9.8.
Please see http://www.openssl.org/news/secadv_20120419.txt for details
of that vulnerability.
This issue only affects OpenSSL 0.9.8v. OpenSSL 1.0.1a and 1.0.0i
already contain a patch sufficient to correct CVE-2012-2110.
Thanks to Red Hat for discovering and fixing this issue.
Affected users should upgrade to 0.9.8w.
