References section.

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.
Programatic management is available via Block Storage’s API.

A flaw was found in the cinder upload-to-image functionality. When
processing a malicious qcow2 header cinder could be tricked into reading
an arbitrary file from the cinder host. (CVE-2015-1851)

All users of openstack-cinder are advised to upgrade to these updated
packages, which correct these issues. After installing the updated
packages, the cinder running services will be restarted automatically.
