Description

Updated CUPS packages that fix a security issue in PDF handling are now available for Red Hat Enterprise Linux 3, 4, and 5.

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

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

Maurycy Prodeus discovered an integer overflow flaw in the way CUPS processes PDF files. An attacker could create a malicious PDF file that could potentially execute arbitrary code when printed. (CVE-2007-3387)

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