OpenStack Nova Denial of Service in network source security groups

Details

Algorithmic complexity vulnerability in OpenStack Compute (Nova) before 2013.1.3 and Havana before havana-3 does not properly handle network source security group policy updates, which allows remote authenticated users to cause a denial of service (nova-network consumption) via a large number of server-creation operations, which triggers a large number of update requests.
