RedHat: RHSA-2011-0455:01 Important: polkit security update
Summary
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.
