<title>GTK+ 2, GdkPixbuf: Multiple XPM decoding vulnerabilities</title>
The GdkPixbuf library, that is also included in GTK+ 2, contains
vulnerabilities that could lead to a Denial of Service or the execution of
arbitrary code.

GTK+ (the GIMP Toolkit) is a toolkit for creating graphical user
interfaces. The GdkPixbuf library provides facilities for image
handling. It is available as a standalone library and also packaged
with GTK+ 2.
iDEFENSE reported a possible heap overflow in the XPM loader
(CVE-2005-3186). Upon further inspection, Ludwig Nussel discovered two
additional issues in the XPM processing functions : an integer overflow
(CVE-2005-2976) that affects only gdk-pixbuf, and an infinite loop
<impact type="normal">
Using a specially crafted XPM image an attacker could cause an
affected application to enter an infinite loop or trigger the
overflows, potentially allowing the execution of arbitrary code.
There is no known workaround at this time.
All GTK+ 2 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose x11-libs/gtk+</code>
All GdkPixbuf users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-libs/gdk-pixbuf-0.22.0-r5&quot;</code>
