OpenStack Compute (Nova) Folsom, Grizzly, and Havana does not properly verify the virtual size of a QCOW2 image, which allows local users to cause a denial of service (host file system disk consumption) via a compressed QCOW2 image. NOTE: this issue is due to an incomplete fix for CVE-2013-2096.

Security readout for executives and security teams

This issue lets a local user consume disk space on an OpenStack Nova compute host by submitting a compressed QCOW2 image whose virtual size is not properly verified. The business impact is denial of service: compute hosts can run out of filesystem capacity and disrupt tenant workloads. Exposure is likely limited to OpenStack Nova environments running Folsom, Grizzly, or Havana where local users can provide QCOW2 images. The source bundle does not identify other affected products or supported-version exposure. Treat as a platform availability issue for legacy OpenStack environments. Prioritize remediation if affected Nova releases are still present or if users can upload images. Current environments outside Folsom, Grizzly, and Havana need vendor confirmation rather than assumption. Mitigation focus: Apply the relevant OpenStack Nova security updates from your vendor or distribution advisory.; Check Ubuntu and Red Hat advisories if those packages are used.; Restrict image upload or registration privileges to trusted users only..
