gtk2 security update

Updated gtk2 packages that fix two security issues are now available.

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

The gtk2 package contains the GIMP ToolKit (GTK+), a library for creating
graphical user interfaces for the X Window System.

A bug was found in the way gtk2 processes XPM images. An attacker could
create a carefully crafted XPM file in such a way that it could cause an
application linked with gtk2 to execute arbitrary code when the file was
opened by a victim. The Common Vulnerabilities and Exposures project has
assigned the name CVE-2005-3186 to this issue.

Ludwig Nussel discovered an infinite-loop denial of service bug in the way
gtk2 processes XPM images. An attacker could create a carefully crafted XPM
file in such a way that it could cause an application linked with gtk2 to
stop responding when the file was opened by a victim. The Common
Vulnerabilities and Exposures project has assigned the name CVE-2005-2975
to this issue.

Users of gtk2 are advised to upgrade to these updated packages, which
contain backported patches and are not vulnerable to these issues.

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