Description Kurt Seifried 2013-08-05 19:58:04 UTC

Jeremy Stanley (jeremy) reports: 

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.

Folsom fix:

Notes:
This fix will be included in the 2013.2.b3 development milestone and
in a future 2013.1.3 release.
