Details

Darragh O'Reilly discovered that the Ubuntu packaging for OpenStack Neutron
did not properly set up its sudo configuration. If a different flaw was
found in OpenStack Neutron, this vulnerability could be used to escalate
privileges. (CVE-2013-6433)

Stephen Ma and Christoph Thiel discovered that the openvswitch-agent in
OpenStack Neutron did not properly perform input validation when creating
security group rules when specifying --remote-ip-prefix. A remote
authenticated attacker could exploit this to prevent application of
additional rules. (CVE-2014-0187)

Thiago Martins discovered that OpenStack Neutron would inappropriately
apply SNAT rules to IPv6 subnets when using the L3-agent. A remote
authenticated attacker could exploit this to prevent floating IPv4
addresses from being attached throughout the cloud. (CVE-2014-4167)
