CVE-2017-17051

An issue was discovered in the default FilterScheduler in OpenStack Nova
16.0.3. By repeatedly rebuilding an instance with new images, an
authenticated user may consume untracked resources on a hypervisor host
leading to a denial of service, aka doubled resource allocations. This
regression was introduced with the fix for OSSA-2017-005 (CVE-2017-16239);
however, only Nova stable/pike or later deployments with that fix applied
and relying on the default FilterScheduler are affected.
