RHEL 3 / 4 / 5 : bzip2 (RHSA-2010:0703)

Medium Nessus Plugin ID 49301

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated bzip2 packages that fix one security issue are now available for Red Hat Enterprise Linux 3, 4, and 5.

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.

bzip2 is a freely available, high-quality data compressor. It provides both standalone compression and decompression utilities, as well as a shared library for use with other programs.

An integer overflow flaw was discovered in the bzip2 decompression routine. This issue could, when decompressing malformed archives, cause bzip2, or an application linked against the libbz2 library, to crash or, potentially, execute arbitrary code. (CVE-2010-0405)

Users of bzip2 should upgrade to these updated packages, which contain a backported patch to resolve this issue. All running applications using the libbz2 library must be restarted for the update to take effect.

Solution

Update the affected bzip2, bzip2-devel and / or bzip2-libs packages.
