RHEL 4 : libpng (RHSA-2006:0205)

high Nessus Plugin ID 20899

Synopsis

The remote Red Hat host is missing a security update for libpng.

Description

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2006:0205 advisory.

The libpng package contains a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files.

A heap based buffer overflow bug was found in the way libpng strips alpha channels from a PNG image. An attacker could create a carefully crafted PNG image file in such a way that it could cause an application linked with libpng to crash or execute arbitrary code when the file is opened by a victim. The Common Vulnerabilities and Exposures project has assigned the name CVE-2006-0481 to this issue.

Please note that the vunerable libpng function is only used by TeTeX and XEmacs on Red Hat Enterprise Linux 4.

All users of libpng are advised to update to these updated packages which contain a backported patch that is not vulnerable to this issue.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL libpng package based on the guidance in RHSA-2006:0205.
