cups security update

Updated cups packages that fix a security issue are now available.

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

The Common UNIX Printing System (CUPS) is a print spooler.

During a source code audit, Chris Evans discovered a number of integer
overflow bugs that affect Xpdf. CUPS contained a copy of the Xpdf code
used for parsing PDF files and was therefore affected by these bugs. The
Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the
name CAN-2004-0888 to this issue, and Red Hat released erratum
RHSA-2004:543 with updated packages.

It was found that the patch used to correct this issue was not sufficient
and did not fully protect CUPS running on 64-bit architectures. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2005-0206 to this issue.

These updated packages also include a fix that prevents the CUPS
initscript from being accidentally replaced.

All users of CUPS on 64-bit architectures should upgrade to these updated
packages, which contain a corrected patch and are not vulnerable to these
issues.

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