OpenStack Security Advisory: 2013-001
CVE: CVE-2013-0208
Date: January 29, 2013
Title: Boot from volume allows access to random volumes
Reporter: Phil Day (HP)
Products: Nova
Affects: Essex, Folsom

Description:
Phil Day from HP reported a vulnerability in volume attachment in
nova-volume, affecting the boot-from-volume feature. By passing a
specific volume ID, an authenticated user may be able to boot from a
volume he doesn't own, potentially resulting in full access to that
3rd-party volume contents. Folsom setups making use of Cinder are not
affected.

Folsom fix (included in upcoming Nova 2012.2.3 stable update):
