@nova-coresec, please review proposed patch.
Here is the updated impact description (removing Icehouse from affected releases):
Title: Nova instance delete in resize state may leak
Reporter: George Shuklin (Webzilla LTD) and Tushar Patil (NTT DATA, Inc)
Products: Nova
Affects: 2014.2 versions through 2014.2.3, and version 2015.1.0
Description:
George Shuklin from Webzilla LTD and Tushar Patil from NTT DATA, Inc independently reported a vulnerability 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.
