CVE-2017-17051 (opens in a new tab)How to fix?
Upgrade Ubuntu:17.10 nova to version 2:16.1.2-0ubuntu1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream nova package and not the nova package as distributed by Ubuntu.
See How to fix? for Ubuntu:17.10 relevant fixed versions and status.
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.
