SCA: security update for nova (GHSA-vq76-rxx3-4r4r)
high Tenable Cloud Security Plugin ID 434297
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- 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. (CVE-2017-17051)
