Ubuntu Security Notice (C) 2011-2016 Canonical, Inc. / NASL script (C) 2011-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Neel Mehta discovered that PolicyKit did not correctly verify the user
making authorization requests. A local attacker could exploit this to
trick pkexec into running applications with root privileges.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Update the affected libpolkit-backend-1-0 package.
