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 < 1.7.0 >= 1.7.0 Description =========== Harald Koenig discovered that sudo incorrectly handles group specifications in Runas_Alias (and related) entries when a group is specified in the list (using %group syntax, to allow a user to run commands as any member of that group) and the user is already a member of that group. Impact ====== A local attacker could possibly run commands as an arbitrary system user (including root). Workaround ========== There is no known workaround at this time. Resolution ========== All sudo users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-admin/sudo-1.7.0" References ========== [ 1 ] CVE-2009-0034 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0034 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200902-01.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.
