"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."
