    Changed Description A race-condition flaw leading to ACL bypass was discovered in OpenStack Networking (neutron). An authenticated user could change the owner of a port after it was created but before firewall rules were applied, thus preventing firewall control checks from occurring. All OpenStack Networking deployments that used either the ML2 plug-in or a plug-in that relied on the security groups AMQP API were affected.
