polkit security update

CentOS Errata and Security Advisory CESA-2014:1359

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.
