Descriptions

The (1) GlusterFS and (2) Linux Smbfs drivers in OpenStack Cinder before 2014.1.3 allows remote authenticated users to obtain file data from the Cinder-volume host by cloning and attaching a volume with a crafted qcow2 header.

Los controladores (1) GlusterFS y (2) Linux Smbfs en OpenStack Cinder anterior a 2014.1.3 permiten a usuarios remotos autenticados obtener datos de ficheros del anfitrión Cinder-volume mediante el clonación y adjunto de un volumen con una cabecera qcow2 manipulada.

OpenStack Block Storage 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.
