title: Nova FilterScheduler doubles resource allocations during rebuild with new image
description: >
Matt Riedemann from Huawei reported a vulnerability in OpenStack Nova's
default FilterScheduler. 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. 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.
