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_p4 >= 1.7.2_p4 Description =========== Multiple vulnerabilities have been discovered in sudo: * Glenn Waller and neonsignal reported that sudo does not properly handle access control of the "sudoedit" pseudo-command (CVE-2010-0426). * Harald Koenig reported that sudo does not properly set supplementary groups when using the "runas_default" option (CVE-2010-0427). Impact ====== A local attacker with privileges to use "sudoedit" or the privilege to execute commands with the "runas_default" setting enabled could leverage these vulnerabilities to execute arbitrary code with elevated privileges. Workaround ========== CVE-2010-0426: Revoke all "sudoedit" privileges, or use the full path to sudoedit. CVE-2010-0427: Remove all occurrences of the "runas_default" setting. Resolution ========== All sudo users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-admin/sudo-1.7.2_p4" References ========== [ 1 ] CVE-2010-0426 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-0426 [ 2 ] CVE-2010-0427 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-0427 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201003-01.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.
