Red Hat Security Advisory 2012-0426-01
Posted Mar 28, 2012
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-0426-01 - OpenSSL is a toolkit that implements the Secure Sockets Layer and Transport Layer Security 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 messages. An attacker could use this flaw to crash an application that uses OpenSSL to decrypt or verify S/MIME messages. A flaw was found in the PKCS#7 and Cryptographic Message Syntax 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.

3. Description:

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 via RHSA-2012:0060 and RHSA-2012:0059, 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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258

5. Bugs fixed (http://bugzilla.redhat.com/):

802489 - CVE-2012-1165 openssl: mime_param_cmp NULL dereference crash
802725 - CVE-2012-0884 openssl: CMS and PKCS#7 Bleichenbacher attack
