CentOS 3 / 4 : openssl096b (CESA-2010:0173)

Critical Nessus Plugin ID 45347

Synopsis

The remote CentOS 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.

Solution

Update the affected openssl096b package.
