Severity: Normal Title: GTK+ 2, GdkPixbuf: Multiple XPM decoding vulnerabilities Date: November 16, 2005 Bugs: #112608 ID: 200511-14
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis ========
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.
Background ==========
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.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-libs/gtk+ < 2.8.6-r1 >= 2.8.6-r1 *>= 2.6.10-r1 < 2.0 2 media-libs/gdk-pixbuf < 0.22.0-r5 >= 0.22.0-r5 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. -------------------------------------------------------------------
Description ===========
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.
Resolution ==========
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"
