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" References ========== [ 1 ] CVE-2005-2975 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-2975 [ 2 ] CVE-2005-2976 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-2976 [ 3 ] CVE-2005-3186 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3186 [ 4 ] iDefense Security Advisory 11.15.05 http://www.idefense.com/application/poi/display?id=339&type=vulnerabilities Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200511-14.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
