Doc Type: Bug Fix
Doc Text:
A denial of service flaw was found in the way OpenStack Compute (nova) looked up VM instances based on an IP address filter. An attacker with sufficient privileges on an OpenStack installation with a large amount of VMs could use this flaw to cause the main nova process to block for an extended amount of time.
