OpenStack Compute (Nova) Folsom, Grizzly, and Havana, when use_cow_images is set to False, does not verify the virtual size of a QCOW2 image, which allows local users to cause a denial of service (host file system disk consumption) by transferring an image with a large virtual size that does not contain a large amount of data from Glance. NOTE: this issue is due to an incomplete fix for CVE-2013-2096.

Security readout for executives and security teams

This is a denial-of-service flaw in legacy OpenStack Nova. Under a specific configuration, a user could cause a compute host to consume excessive disk space by using a compressed QCOW2 image whose declared virtual size was not properly checked. Exposure appears limited to legacy OpenStack Nova deployments running Folsom, Grizzly, or Havana with use_cow_images set to False and users able to supply or launch Glance images. Prioritize if the organization still operates legacy OpenStack clouds or allows tenant-provided images. The business risk is service disruption from full compute-host disks, not data theft or code execution based on the supplied evidence. Mitigation focus: Apply vendor-provided Nova security updates for CVE-2013-4469.; Review OpenStack and Ubuntu advisories for supported package versions.; Check whether use_cow_images can be safely enabled in affected environments..
