A race-condition flaw leading to ACL bypass was discovered in OpenStack Networking (neutron). An authenticated user could change the owner of a port after it was created but before firewall rules were applied, thus preventing firewall control checks from occurring. All OpenStack Networking deployments that used either the ML2 plug-in or a plug-in that relied on the security groups AMQP API were affected.

Race condition in OpenStack Neutron before 2014.2.4 and 2015.1 before 2015.1.2, when using the ML2 plugin or the security groups AMQP API, allows remote authenticated users to bypass IP anti-spoofing controls by changing the device owner of a port to start with network: before the security group rules are applied.

Condición de carrera en OpenStack Neutron en versiones anteriores 2014.2.4 and 2015.1 en versiones anteriores 2015.1.2, cuando se utiliza el plugin ML2 o los grupos de seguridad de API AMQP, permite a usuarios remotos autenticados eludir controles IP anti-spoofing cambiando el propietario del dispositivo de un puerto para empezar con la red: antes de que las reglas de seguridad de grupo sean aplicadas.
