Description

An updated libjpeg package that fixes one security issue is now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate 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.

The libjpeg package contains a library of functions for manipulating JPEG images. It also contains simple client programs for accessing the libjpeg functions.

An uninitialized memory read issue was found in the way libjpeg decoded images with missing Start Of Scan (SOS) JPEG markers. A remote attacker could create a specially crafted JPEG image that, when decoded, could possibly lead to a disclosure of potentially sensitive information. (CVE-2013-6629)

All libjpeg users are advised to upgrade to this updated package, which contains a backported patch to correct this issue.
