The libvirt driver in OpenStack Compute (Nova) before 2013.2.2 and icehouse before icehouse-2 allows remote authenticated users to cause a denial of service (disk consumption) by creating and deleting instances with unique os_type settings, which triggers the creation of a new ephemeral disk backing file.

CVE-2013-6437 openstack-nova: DoS through ephemeral disk backing files
Thierry Carrez of the OpenStack project reports:
Title: Nova compute DoS through ephemeral disk backing files
Reporter: Phil Day (HP)
Products: Nova
Affects: All supported versions
Description:
Phil Day from HP reported a vulnerability in the libvirt driver handling
of ephemeral disk backing files on Nova compute nodes. By repeatedly
creating snapshots, changing the os_type to a new random value, and
spawning new instances from the snapshot (and quickly deleting those
instances), an authenticated user could generate lots of different
ephemeral disk backing files and fill up compute node disks, potentially
resulting in a Denial of Service against a Nova setup. Only Nova setups
running the libvirt driver are affected.
