1. Summary:

Updated CUPS packages that fix a security issue are now available for Red
Hat Enterprise Linux.

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Problem description:

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

A bug was found in the way CUPS processes malformed HTTP requests. It is
possible for a remote user capable of connecting to the CUPS daemon to
issue a malformed HTTP GET request that causes CUPS to enter an
infinite loop. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2005-2874 to this issue.

Two small bugs have also been fixed in this update.  A signal handling
problem has been fixed that could occasionally cause the scheduler to stop
when told to reload.  A problem with tracking open file descriptors under
certain specific circumstances has also been fixed.

All users of CUPS should upgrade to these erratum packages, which contain a
patch to correct this issue.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  Use Red Hat
Network to download and update your packages.  To launch the Red Hat
Update Agent, use the following command:

    up2date

For information on how to install packages manually, refer to the
following Web page for the System Administration or Customization
guide specific to your system:

5. Bug IDs fixed (http://bugzilla.redhat.com/):

164641 - [PATCH] cupsd segfault when SIGCHLD received
164642 - Cupsd hangs on reading pipe with recycled file descriptor.
168072 - CAN-2005-2874 Malformed HTTP Request URL denial of service
