Synopsis
The remote Red Hat host is missing a security update for polkit-qt.Description
The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2014:1359 advisory.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.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Update the RHEL polkit-qt package based on the guidance in RHSA-2014:1359.See Also
