CVE-2013-4261

En OpenStack Compute (Nova) Folsom, Grizzly, y anteriores, cuando se utiliza Apache Qpid para el backend RPC, no maneja adecuadamente los errores que se producen durante la mensajería, que permite a atacantes remotos provocar una denegación de servicio (conexión consumo piscina), como lo demuestra el uso de múltiples solicitudes que envían cadenas largas a una consola de instancia y recuperar el registro de la consola.

It was discovered that Nova did not properly enforce the is_public property when determining flavor access. An authenticated attacker could exploit this to obtain sensitive information in private flavors. This issue only affected Ubuntu 12.10 and 13.10. Grant Murphy discovered that Nova would allow XML entity processing. A remote unauthenticated attacker could exploit this using the Nova API to cause a denial of service via resource exhaustion. This issue only affected Ubuntu 13.10. Various other issues were also addressed.
