Descriptions

OpenStack Compute (nova) 2015.1 through 2015.1.1, 2014.2.3, and earlier does not stop the migration process when the instance is deleted, which allows remote authenticated users to cause a denial of service (disk, network, and other resource consumption) by resizing and then deleting an instance.

Vulnerabilidad en OpenStack Compute (nova) 2015.1 hasta la versión 2015.1.1, 2014.2.3 y anteriores, no detiene el proceso de migración cuando se borra la instancia, lo que permite a usuarios remotos autenticados causar una denegación de servicio (disco, red y otros consumos de memoria) modificando el tamaño y borrándo entonces la instancia.

A denial of service flaw was found in the OpenStack Compute (nova) instance migration process. Because the migration process does not terminate when an instance is deleted, an authenticated user could bypass user quota and deplete all available disk space by repeatedly re-sizing and deleting an instance.
