title: Arbitrary file access through custom QCOW2 external data

description: >
  Martin Kaesberger reported a vulnerability in QCOW2 image processing for
  Cinder, Glance and Nova. By supplying a specially created QCOW2 image which
  references a specific data file path, an authenticated user may convince
  systems to return a copy of that file's contents from the server resulting in
  unauthorized access to potentially sensitive data. All Cinder deployments are
  affected; only Glance deployments with image conversion enabled are affected;
  all Nova deployments are affected.
