Synopsis
Moderate: tk security update
Type/Severity
Security Advisory Moderate
Topic
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.
Description
Tk is a graphical toolkit for the Tcl scripting language.
An input validation flaw was discovered in Tk's GIF image handling. A code-size value read from a GIF image was not properly validated before being used, leading to a buffer overflow. A specially crafted GIF file 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.
