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.
