In OpenStack Nova through 14.0.9, 15.x through 15.0.7, and 16.x through
16.0.2, by rebuilding an instance, an authenticated user may be able to
circumvent the Filter Scheduler bypassing imposed filters (for example, the
ImagePropertiesFilter or the IsolatedHostsFilter). All setups using Nova
Filter Scheduler are affected. Because of the regression described in
Launchpad Bug #1732947, the preferred fix is a 14.x version after 14.0.10,
a 15.x version after 15.0.8, or a 16.x version after 16.0.3.
