Address the critical polkit-qt vulnerability in Red Hat Enterprise Linux by applying this crucial advisory patch.
Updated polkit-qt packages that fix one security issue are now available for Red Hat Enterprise Linux 7

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/articles/11258

Summary

Polkit-qt is a library that lets developers use the PolicyKit API through a Qt-styled API. The polkit-qt library is used by the KDE Authentication Agent (KAuth), which is a part of kdelibs.
It was found that polkit-qt handled authorization requests with PolicyKit via a D-Bus API that is vulnerable to a race condition. A local user could use this flaw to bypass intended PolicyKit authorizations. This update modifies polkit-qt to communicate with PolicyKit via a different API that is not vulnerable to the race condition. (CVE-2014-5033)
All polkit-qt users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
