The libvirt driver in OpenStack Compute (Nova) before 2013.2.2 and icehouse before icehouse-2 allows remote authenticated users to cause a denial of service (disk consumption) by creating and deleting instances with unique os_type settings, which triggers the creation of a new ephemeral disk backing file.

Security readout for executives and security teams

This flaw lets an authenticated OpenStack Nova user consume compute-node disk space by causing repeated creation of unique ephemeral disk backing files. The business impact is service disruption, not data theft, but cloud platforms with tenant self-service instance creation could be affected if running old vulnerable Nova releases. Exposure is most likely in legacy OpenStack environments using Nova with the libvirt driver and allowing authenticated users or tenants to create instances. Modern deployments are unlikely to be exposed unless they retain unpatched 2013-era Nova packages. Treat as a legacy cloud availability risk. Prioritize only if the organization still operates old OpenStack Nova deployments with tenant self-service provisioning; otherwise track as historical exposure. Mitigation focus: Upgrade Nova to a fixed vendor-supported release or apply the referenced OpenStack and Red Hat updates.; Check vendor guidance for the exact package versions required in your distribution.; Limit instance creation permissions to trusted users until vulnerable systems are remediated..
