Proposed impact description...
Title: Denial of Service in Nova network source security groups
Reporter: Vishvananda Ishaya (Nebula)
Products: Nova
Affects: All versions
Vishvananda Ishaya from Nebula reported a denial of service
vulnerability in Nova's handling of network source security group
policy updates. By performing a large number of server creation
operations, the proportion of updates increases quadratically and
may overwhelm nova-network such that it is no longer able to service
other requests in a timely fashion. Only setups relying on
nova-network are affected.
