CVE-2013-6437 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 2.02% chance of exploitation in the next 30 days.
