Background ========== LibAST is a utility library that was originally intended to accompany Eterm, but may be used by various other applications. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-libs/libast < 0.7 >= 0.7 Description =========== Michael Jennings discovered an exploitable buffer overflow in the configuration engine of LibAST. Impact ====== The vulnerability can be exploited to gain escalated privileges if the application using LibAST is setuid/setgid and passes a specifically crafted filename to LibAST's configuration engine. Workaround ========== Identify all applications linking against LibAST and verify they are not setuid/setgid. Resolution ========== All users should upgrade to the latest version and run revdep-rebuild: # emerge --sync # emerge --ask --oneshot --verbose >=x11-libs/libast-0.7 # revdep-rebuild References ========== [ 1 ] CVE-2006-0224 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0224 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200601-14.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.
