neutron vulnerabilities
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)
