                   Red Hat Security Advisory

Synopsis:          Moderate: cups security update
Advisory ID:       RHSA-2008:1028-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2008-1028.html

=====================================================================

1. Summary:

Updated cups packages that fix a security issue are now available for Red
Hat Enterprise Linux 3.

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Description:

The Common UNIX® Printing System (CUPS) provides a portable printing layer
for UNIX operating systems.

An integer overflow flaw, leading to a heap buffer overflow, was discovered
in the Portable Network Graphics (PNG) decoding routines used by the CUPS
image-converting filters, "imagetops" and "imagetoraster". An attacker
could create a malicious PNG file that could, potentially, execute
arbitrary code as the "lp" user if the file was printed. (CVE-2008-5286)

CUPS users should upgrade to these updated packages, which contain a
backported patch to correct this issue.

4. Solution:

Before applying this update, make sure that all previously-released errata
relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red
Hat Network to apply this update are available at
