Background ========== sudo allows a system administrator to give users the ability to run commands as other users. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-admin/sudo < 1.6.8_p9 >= 1.6.8_p9 Description =========== The sudoers file is used to define the actions sudo users are permitted to perform. Charles Morris discovered that a specific layout of the sudoers file could cause the results of an internal check to be clobbered, leaving sudo vulnerable to a race condition. Impact ====== Successful exploitation would permit a local sudo user to execute arbitrary commands as another user. Workaround ========== Reorder the sudoers file using the visudo utility to ensure the 'ALL' pseudo-command precedes other command definitions. Resolution ========== All sudo users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-admin/sudo-1.6.8_p9" References ========== [ 1 ] Sudo Announcement http://www.sudo.ws/sudo/alerts/path_race.html Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200506-22.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.
