3. Description:

OpenStack Networking (neutron) is a pluggable, scalable, and API-driven system that provisions networking services to virtual machines. Its main function is to manage connectivity to and from virtual machines.

A race-condition flaw leading to ACL bypass was discovered in OpenStack Networking. 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. (CVE-2015-5240)

Red Hat would like to thank the OpenStack project for reporting this issue. Upstream acknowledges Kevin Benton from Mirantis as the original reporter.

All openstack-neutron users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
