Background ========== libXpm is a pixmap manipulation library for the X Window System, included in X.org. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-base/xorg-x11 < 6.8.2-r1 *>= 6.8.0-r5 >= 6.8.2-r1 Description =========== Chris Gilbert has discovered potentially exploitable buffer overflow cases in libXpm that weren't fixed in previous libXpm versions. Impact ====== A carefully-crafted XPM file could crash X.org, potentially allowing the execution of arbitrary code with the privileges of the user running the application. Workaround ========== There is no known workaround at this time. Resolution ========== All X.org users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose x11-base/xorg-x11 References ========== [ 1 ] CAN-2005-0605 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0605 [ 2 ] Freedesktop bug https://bugs.freedesktop.org/show_bug.cgi?id=1920 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200503-15.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.
