RedHat: RHSA-2014-1788:01 Moderate: openstack-cinder security and bug fix
Summary
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 GlusterFS and Linux smbfs drivers for OpenStack
Block Storage. A remote attacker could use this flaw to disclose an
arbitrary file from the cinder-volume host to a virtual instance by cloning
and attaching a volume with a malicious qcow2 header. (CVE-2014-3641)
Red Hat would like to thank the OpenStack project for reporting this issue.
Upstream acknowledges Duncan Thomas from Hewlett Packard as the original
reporter.
The openstack-cinder packages have been upgraded to upstream version
2014.1.3, which provides a number of bug fixes over the previous version.
(BZ#1149739)
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.
