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


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

Andrew Griffiths discovered that QEMU did not correctly drop
privileges when using the 'runas' argument. Under certain
circumstances a local attacker could exploit this to escalate
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.

Solution :

Update the affected qemu-kvm, qemu-kvm-extras and / or
qemu-kvm-extras-static packages.

Risk factor :

Low / CVSS Base Score : 2.1
