GLSA-200511-14 : GTK+ 2, GdkPixbuf: Multiple XPM decoding vulnerabilities

Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200511-14
(GTK+ 2, GdkPixbuf: Multiple XPM decoding vulnerabilities)

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
(CVE-2005-2975).

Impact :

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.

Workaround :

There is no known workaround at this time.

Solution :

All GTK+ 2 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose x11-libs/gtk+
All GdkPixbuf users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=media-libs/gdk-pixbuf-0.22.0-r5'

Risk factor :

High / CVSS Base Score : 7.8
(CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:C)
