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.

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.
