Ubuntu Security Notice (C) 2013 Canonical, Inc. / NASL script (C) 2013 Tenable Network Security, Inc.
The remote Ubuntu host is missing a security-related patch.
USN-1831-1 fixed a vulnerability in OpenStack Nova. The upstream fix
introduced a regression where instances using uncached QCOW2 images
would fail to start. This update fixes the problem.
We apologize for the inconvenience.
Loganathan Parthipan discovered that Nova did not verify the size of
QCOW2 instance storage. An authenticated attacker could exploit this
to cause a denial of service by creating an image with a large virtual
size with little data, then filling the virtual disk.
Update the affected python-nova package.
