Ubuntu Security Notice USN-1663-1
December 12, 2012

nova vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.10


Nova could be made to expose sensitive information.

Software Description:
- nova: OpenStack Compute cloud infrastructure


Eric Windisch discovered that Nova did not properly clear LVM-backed images
before they were reallocated which could potentially lead to an information
leak. This issue only affected setups using libvirt LVM-backed instances.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.10:
  python-nova                     2012.2-0ubuntu5.2

In general, a standard system update will make all the necessary changes.
