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 thistime. 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 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200411-28 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.
