Name of the Vulnerable Software and Affected Versions OpenStack Nova versions 16.0.3

Description An issue in the default FilterScheduler allows an authenticated user to cause a denial of service by consuming untracked resources on a hypervisor host through repeated instance rebuilding with new images. This leads to doubled resource allocations.

Recommendations For OpenStack Nova version 16.0.3, consider disabling the default FilterScheduler as a temporary workaround until a patch is available. Restrict access to instance rebuilding with new images to minimize the risk of exploitation.
