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

PolicyKit is a toolkit for defining and handling authorizations.

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
