3. Description:

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

An integer overflow flaw leading to a heap buffer overflow was discovered
in the Portable Network Graphics (PNG) decoding routines used by the CUPS
image converting filters "imagetops" and "imagetoraster". An attacker could
create a malicious PNG file that could possibly execute arbitrary code as
the "lp" user if the file was printed. (CVE-2008-1722)

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

4. Solution:

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
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/FAQ_58_10188

5. Bugs fixed (http://bugzilla.redhat.com/):
