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

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