Description Summer Long 2016-09-22 22:46:14 EDT 
If an authenticated user deletes an instance while it is in resize state, it
will cause the original instance to not be deleted from the compute
node it was running on. An attacker can use this to launch a denial of
service attack. All Nova setups are affected.
