openstack-nova: Nova FilterScheduler doubles resource allocations during rebuild with new image

Published Dec 5, 2017 CVSS 3.0 · 8.6 High EPSS 2.0% KEV · Not listed
Description
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.
