1. Summary:

Updated tk packages that fix a security issue 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

could use this to cause a crash or, potentially, execute code with the
privileges of the application using the Tk graphical toolkit.
(CVE-2008-0553)

A buffer overflow flaw was discovered in Tk's animated GIF image handling.
An animated GIF containing an initial image smaller than subsequent images
could cause a crash or, potentially, execute code with the privileges of
the application using the Tk library. (CVE-2007-5137)

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