Description Garth Mollett 2014-03-19 00:48:41 EDT 
Stanislaw Pitucha from Hewlett Packard reported a vulnerability in the
Nova instance rescue mode. By overwriting the disk inside an instance
with a malicious image and switching the instance to rescue mode, an
authenticated user would be able to leak an arbitrary file from the
compute host to the virtual instance. Note that the host file must be
readable by the libvirt/kvm context to be exposed. Only setups using
libvirt to spawn instance, and having "use_cow_images = False" in Nova
configuration are affected.
