RHEL 3 / 4 : openssl096b (RHSA-2010:0173)

Synopsis :

The remote Red Hat host is missing a security update.

Description :

Updated openssl096b packages that fix one security issue are now
available for Red Hat Enterprise Linux 3 and 4.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System
(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.

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.

It was discovered that OpenSSL did not always check the return value
of the bn_wexpand() function. An attacker able to trigger a memory
allocation failure in that function could cause an application using
the OpenSSL library to crash or, possibly, execute arbitrary code.
(CVE-2009-3245)

All openssl096b users should upgrade to these updated packages, which
contain a backported patch to resolve this issue. For the update to
take effect, all programs using the openssl096b library must be
restarted.
