Background ========== fvwm is a highly configurable virtual window manager for X11 desktops. fvwm-menu-directory allows fvwm users to browse directories from within fvwm. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-wm/fvwm < 2.5.18-r1 >= 2.5.18-r1 Description =========== Tavis Ormandy of the Gentoo Linux Security Audit Team discovered that fvwm-menu-directory does not sufficiently sanitise directory names prior to generating menus. Impact ====== A local attacker who can convince an fvwm-menu-directory user to browse a directory they control could cause fvwm commands to be executed with the privileges of the fvwm user. Fvwm commands can be used to execute arbitrary shell commands. Workaround ========== There is no known workaround at this time. Resolution ========== All fvwm users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=x11-wm/fvwm-2.5.18-r1" References ========== [ 1 ] CVE-2006-5969 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-5969 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200611-17.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.
