3. Description:

OpenStack Block Storage (cinder) manages block storage mounting and the
presentation of such mounted block storage to instances. The backend
physical storage can consist of local disks, or Fiber Channel, iSCSI, and
NFS mounts attached to Compute nodes. In addition, Block Storage supports
volume backups, and snapshots for temporary save and restore operations.
Programmatic management is available via Block Storage's API.

Security Fix(es):

* A resource vulnerability in the Block Storage (cinder) service was found
in its use of qemu-img. An unprivileged user could consume as much as 4 GB
of RAM on the compute host by uploading a malicious image. This flaw could
lead possibly to host out-of-memory errors and negatively affect other
running tenant instances. (CVE-2015-5162)
