Descriptions
The libvirt driver in OpenStack Compute (Nova) before 2013.2.2 and icehouse before icehouse-2 allows remote authenticated users to cause a denial of service (disk consumption) by creating and deleting instances with unique os_type settings, which triggers the creation of a new ephemeral disk backing file.
El controlador libvirt en OpenStack Compute (Nova) anterior a 2013.2.2 y icehouse anterior a icehouse-2 permite a usuarios remotos autenticados causar una denegación de servicio (consumo de disco) mediante creación y eliminación de instancias con configuraciones os_type únicas, lo que provoca la creación de un archivo de respaldo de disco efímero nuevo.
