"From Red Hat Security Advisory 2014:1359 :

Updated polkit-qt packages that fix one security issue are now
available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Important
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the References section.

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."
