Important: cups security update

Updated cups packages that fix a security issue 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. The Internet Printing Protocol (IPP) is a
standard network protocol for remote printing, as well as managing print
jobs.

A flaw was found in the way CUPS handles the addition and removal of remote
shared printers via IPP. A remote attacker could send malicious UDP IPP
packets causing the CUPS daemon to crash. (CVE-2008-0882)

Note: the default configuration of CUPS on Red Hat Enterprise Linux 5 will
only accept requests of this type from the local subnet. This issue did not
affect the versions of CUPS as shipped with Red Hat Enterprise Linux 3 or
4.

All cups users are advised to upgrade to these updated packages, which
contain a backported patch to resolve this issue.

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
