Descriptions
When using the Linux bridge ml2 driver, non-privileged tenants are able to create and attach ports without specifying an IP address, bypassing IP address validation. A potential denial of service could occur if an IP address, conflicting with existing guests or routers, is then assigned from outside of the allowed allocation pool. Versions of openstack-neutron before 13.0.0.0b2, 12.0.3 and 11.0.5 are vulnerable.
Al emplear el controlador de Linux bridge ml2, los inquilinos sin privilegios pueden crear y adjuntar puertos sin especificar una dirección IP, omitiendo la validación de direcciones IP. Podría ocurrir una denegación de servicio (DoS) si una dirección IP, en conflicto con invitados o routers existentes, se asigna desde fuera del grupo de asignación permitido. Las versiones de openstack-neutron anteriores a la 13.0.0.0b2, 12.0.3 y 11.0.5 son vulnerables.
