Synopsis

Important: openssl096b security update

Type/Severity

Security Advisory: Important

Topic

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.

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.

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.

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
