Descriptions

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.

El agente L3 en OpenStack Neutron anterior a 2013.2.4, 2014.x anterior a 2014.1.2 y Juno anterior a Juno-2 permite a usuarios remotos autenticados causar una denegación de servicio (interrupción de adjunto de dirección IPv4) al adjuntar una subred IPv6 privada a un router L3.

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. 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. Various other issues were also addressed.
