Synopsis: Moderate: openssl security and bug fix update
Issue Date: 2012-03-27
CVE Numbers: CVE-2012-1165
 CVE-2012-0884

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3)
and Transport Layer Security (TLS v1) protocols, as well as a
full-strength, general purpose cryptography library.

A NULL pointer dereference flaw was found in the way OpenSSL parsed
Secure/Multipurpose Internet Mail Extensions (S/MIME) messages. An attacker
could use this flaw to crash an application that uses OpenSSL to decrypt or
verify S/MIME messages. (CVE-2012-1165)

A flaw was found in the PKCS#7 and Cryptographic Message Syntax (CMS)
implementations in OpenSSL. An attacker could possibly use this flaw to
perform a Bleichenbacher attack to decrypt an encrypted CMS, PKCS#7, or
S/MIME message by sending a large number of chosen ciphertext messages to
a service using OpenSSL and measuring error response times. (CVE-2012-0884)

This update also fixes a regression caused by the fix for CVE-2011-4619,
released in a previous update, which caused Server Gated Cryptography
(SGC) handshakes to fail.

All OpenSSL users should upgrade to these updated packages, which contain
backported patches to resolve these issues. For the update to take effect,
all services linked to the OpenSSL library must be restarted, or the system
rebooted.
