An issue was discovered in the iptables firewall module in OpenStack Neutron before 10.0.8, 11.x before 11.0.7, 12.x before 12.0.6, and 13.x before 13.0.3. By setting a destination port in a security group rule along with a protocol that doesn't support that option (for example, VRRP), an authenticated user may block further application of security group rules for instances from any project/tenant on the compute hosts to which it's applied. (Only deployments using the iptables security group driver are affected.)

Se ha detectado un fallo en el módulo de firewall iptables en OpenStack Neutron en versiones anteriores a la 10.0.8, en las 11.x anteriores a la 11.0.7, en las 12.x anteriores a la 12.0.6 y en las 13.x anteriores a la 13.0.3. Al establecer un puerto de destino en una regla de grupo de seguridad, junto con un protocolo que no soporta dicha opción (p.ej., VRRP), un usuario autenticado podría bloquear la mayor aplicación de esas reglas de grupo de seguridad para instancias desde cualquier project/tenant en los hosts de computación a los cuales se aplican. (Solamente despliegues que empleen el grupo de seguridad iptables se ven afectados.)
