CVE 2014-2573
The VMWare driver in OpenStack Compute (Nova) 2013.2 through 2013.2.2 does not properly put VMs into RESCUE status, which allows remote authenticated users to bypass the quota limit and cause a denial of service (resource consumption) by requesting the VM be put into rescue and then deleting the image.
