Description Martin Prpič 2015-10-06 11:47:48 UTC

Title: Nova network security group changes are not applied to running instances

Reporter: Sreekumar S and Suntao
Products: Nova
Affects: <=2014.2.3, >=2015.1.0, <=2015.1.1

Description:

Sreekumar S and Suntao independently reported a vulnerability in Nova network. Security group changes silently fail to be applied to already running instances, potentially resulting in instances not being protected by the security group. All Nova network setups are affected.
