Description Andrej Nemec 2016-09-21 12:38:28 UTC 
It was reported from upstream that a vulnerability was found in Nova resize state. 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.

This vulnerability is similar to OSSA-2015-017 (CVE-2015-3280) and was re-introduced in the first release of Mitaka version of Nova and it was re-fixed in nova-13.1.0.
