Descriptions

Algorithmic complexity vulnerability in OpenStack Compute (Nova) before 2013.1.3 and Havana before havana-3 does not properly handle network source security group policy updates, which allows remote authenticated users to cause a denial of service (nova-network consumption) via a large number of server-creation operations, which triggers a large number of update requests.

Vulnerabilidad de la complejidad algorítmica en OpenStack Compute (Nova) anteriores 03/01/2013 y Havana anterior a habana-3 no controla correctamente las actualizaciones de directiva de grupo de seguridad de código de red, lo que permite a usuarios remotos autenticados causar una denegación de servicio (consumo nova de la red) a través de una gran número de operaciones del servidor de creación, que desencadena un gran número de solicitudes de actualización.
