Detail
Problem Description: Updated polkit packages that fix one security issue are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch, x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, noarch, x86_64 3. Description: PolicyKit is a toolkit for defining and handling authorizations. A race condition flaw was found in the PolicyKit pkexec utility and polkitd daemon. A local user could use this flaw to appear as a privileged user to pkexec, allowing them to execute arbitrary commands as root by running those commands with pkexec. (CVE-2011-1485) Red Hat would like to thank Neel Mehta of Google for reporting this issue. All polkit users should upgrade to these updated packages, which contain backported patches to correct this issue. The system must be rebooted for this update to take effect. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 692922 - CVE-2011-1485 polkitd/pkexec vulnerability |
