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

high Nessus Plugin ID 20235

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'
