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 < 1.7.2_p6 >= 1.7.2_p6 Description =========== The command matching functionality does not properly handle when a file in the current working directory has the same name as a pseudo-command in the sudoers file and the PATH contains an entry for ".". Impact ====== A local attacker with the permission to run sudoedit could, under certain circumstances, execute arbitrary commands as whichever user he has permission to run sudoedit as, typically 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-1.7.2_p6" References ========== [ 1 ] CVE-2010-1163 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-1163 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201006-09.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.
