CVE have been requested with this description (same as comment #20, including 2014.1.4 in affected versions):
Title: Host file disclosure through qcow2 backing file
Reporter: Bastian Blank (credativ)
Products: Cinder and Nova
Affects: up to 2014.1.4 and 2014.2 versions through 2014.2.2
Description:
Bastian Blank from credativ reported a vulnerability in Cinder and Nova. By overwriting an image with a malicious qcow2 header, an authenticated user may mislead Cinder upload-to-image action, resulting in disclosure of any file from the Cinder server. A similar vulnerability in Nova can also be used by an authenticated user to trick Nova during a snapshot upload, resulting in disclosure of any file for which the Nova process user has access to. All Cinder and Nova setups are affected.
