Vulnerability Assessment Details
GTK+ 2, GdkPixbuf: Multiple XPM decoding vulnerabilities
Detailed Explanation for this Vulnerability Assessment
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
Using a specially crafted XPM image a possible hacker could cause an
affected application to enter an infinite loop or trigger the
overflows, potentially permiting 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+
All GdkPixbuf users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/gdk-pixbuf-0.22.0-r5"
Network Security Threat Level: Medium
