3. Description:

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.

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
