Title: RHSA-2014:1359: polkit-qt security update (Important)
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.
