Background ========== libXpm is a pixmap manipulation library for the X Window System, included in both X.Org and XFree86. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-base/xorg-x11 < 6.8.0-r3 >= 6.8.0-r3 *>= 6.7.0-r3 2 x11-base/xfree < 4.3.0-r8 >= 4.3.0-r8 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Several issues were discovered in libXpm, including integer overflows, out-of-bounds memory accesses, insecure path traversal and an endless loop. Impact ====== An attacker could craft a malicious pixmap file and entice a user to use it with an application linked against libXpm. This could lead to Denial of Service or arbitrary code execution. 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-x11-6.7.0-r3" All XFree86 users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=x11-base/xfree-x11-4.3.0-r8" References ========== [ 1 ] CAN-2004-0914 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0914 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200411-28.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.
