CentOS 5 / 6 : libpng (CESA-2012:0407)

medium Nessus Plugin ID 58404

Language:

Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated libpng packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6.

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 libpng packages contain a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files.

A heap-based buffer overflow flaw was found in the way libpng processed compressed chunks in PNG image files. An attacker could create a specially crafted PNG image file that, when opened, could cause an application using libpng to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2011-3045)

Users of libpng should upgrade to these updated packages, which correct this issue. For Red Hat Enterprise Linux 5, they contain a backported patch. For Red Hat Enterprise Linux 6, they upgrade libpng to version 1.2.48. All running applications using libpng must be restarted for the update to take effect.

Solution

Update the affected libpng packages.
