Description Kurt Seifried 2012-12-05 20:16:45 UTC 
Thierry Carrez (thierry) has released information 

Title: Information leak in libvirt LVM-backed instances
Reporter: Eric Windisch (Cloudscaling)
Products: Nova
Affects: Folsom, Grizzly

Description:
Eric Windisch from Cloudscaling reported a vulnerability in libvirt
LVM-backed instances. The physical volume content was not wiped out
before being reallocated and passed to an instance, which may result in
the disclosure of information from previously-allocated logical volumes.
Only setups using libvirt and LVM-backed instances
(libvirt_images_type=lvm) are affected.

This was originally reported by Eric Windisch from Cloudscaling
