Descriptions

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.

El proceso openvswitch-agent en OpenStack Neutron 2013.1 anterior a 2013.2.4 y 2014.1 anterior a 2014.1.1 permite a usuarios remotos autenticados evadir restricciones de seguridad de grupo a través de un CIDR invalido en una regla de seguridad de grupo, lo que previene que se aplican más reglas.

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.
