"Updated CUPS packages that fix several security issues are now
available for Red Hat Enterprise Linux 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.

Alin Rad Pop discovered several flaws in the handling of PDF files. An
attacker could create a malicious PDF file that would cause CUPS to
crash or potentially execute arbitrary code when printed.
(CVE-2007-4352, CVE-2007-5392, CVE-2007-5393)

All CUPS users are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues."
