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 (CVE-2005-2975).
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:
Code Listing 3.1: Resolution |
# emerge --sync # emerge --ask --oneshot --verbose x11-libs/gtk+ |
All GdkPixbuf users should upgrade to the latest version:
Code Listing 3.2: Resolution |
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/gdk-pixbuf-0.22.0-r5" |
