The openvswitch-agent process in OpenStack Neutron 2013.1 before 2013.2.4 and 2014.1 before 2014.1.1 allows remote authenticated users to bypass security group restrictions via an invalid CIDR in a security group rule, which prevents further rules from being applied.

Kashyap Chamarthy <kchamart> reports:

It's possible for Neutron (OpenStack networking) users to pass arbitrary config files via rootwrap[] which allows privilege escalation by letting user add more exec directories, change configurations of commands using rootwrap, log more than what needs to be done, etc.

The L3-agent in OpenStack Neutron before 2013.2.4, 2014.x before 2014.1.2, and Juno before Juno-2 allows remote authenticated users to cause a denial of service (IPv4 address attachment outage) by attaching an IPv6 private subnet to a L3 router.
