Background ========== PolicyKit is a toolkit for controlling privileges for system-wide services. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-auth/polkit < 0.104-r1 >= 0.104-r1 Description =========== Multiple vulnerabilities have been found in PolicyKit: * Error messages in the pkexec utility disclose the existence of local files (CVE-2010-0750). * The pkexec utility initially checks the effective user ID of its parent process for authorization, instead of checking the real user ID (CVE-2011-1485). * Members of the "wheel" group are able to execute commands as an administrator without a password (CVE-2011-4945). Impact ====== A local attacker could gain elevated privileges or sensitive information. Workaround ========== There is no known workaround at this time. Resolution ========== All PolicyKit users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=sys-auth/polkit-0.104-r1" References ========== [ 1 ] CVE-2010-0750 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-0750 [ 2 ] CVE-2011-1485 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-1485 [ 3 ] CVE-2011-4945 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-4945 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201204-06.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.
