=====================================================================

1. Summary:

Updated cups packages that fix multiple security issues are now available
for Red Hat Enterprise Linux 5.

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 Desktop (v. 5 client) - i386, x86_64
RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

3. Description:

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

A heap buffer overflow flaw was found in a CUPS administration interface
CGI script. A local attacker able to connect to the IPP port (TCP port 631)
could send a malicious request causing the script to crash or, potentially,
execute arbitrary code as the "lp" user. Please note: the default CUPS
configuration in Red Hat Enterprise Linux 5 does not allow remote
connections to the IPP TCP port. (CVE-2008-0047)

Red Hat would like to thank "regenrecht" for reporting this issue.

This issue did not affect the versions of CUPS as shipped with Red Hat
Enterprise Linux 3 or 4.

Two overflows were discovered in the HP-GL/2-to-PostScript filter. An
attacker could create a malicious HP-GL/2 file that could possibly execute
arbitrary code as the "lp" user if the file is printed. (CVE-2008-0053)

A buffer overflow flaw was discovered in the GIF decoding routines used by
CUPS image converting filters "imagetops" and "imagetoraster". An attacker
could create a malicious GIF file that could possibly execute arbitrary
code as the "lp" user if the file was printed. (CVE-2008-1373)

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

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
