Advisory: RHSA-2006:0205-4
Type: Security Advisory
Severity: Moderate
Issued on: 2006-02-13
Last updated on: 2006-02-13
Affected Products: Red Hat Desktop (v. 4)

CVEs (cve.mitre.org): CVE-2006-0481

Details

Updated libpng packages that fix a security issue are now available for Red
Hat Enterprise Linux 4.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

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.
