RHEL 2.1 / 3 : libpng (RHSA-2004:180)

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

Updated libpng packages that fix a out of bounds memory access are now
available.

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

Steve Grubb discovered a out of bounds memory access flaw in libpng.
An attacker could carefully craft a PNG file in such a way that it
would cause an application linked to libpng to crash when opened by a
victim. This issue may not be used to execute arbitrary code.

Users are advised to upgrade to these updated packages that contain a
backported security fix not vulnerable to this issue.
