Descriptions

The V3 API in OpenStack Identity (Keystone) 2013.1 before 2013.2.4 and icehouse before icehouse-rc2 allows remote attackers to cause a denial of service (CPU consumption) via a large number of the same authentication method in a request, aka "authentication chaining."

La API V3 en OpenStack Identity (Keystone) 2013.1 anterior a 2013.2.4 y icehouse anterior a icehouse-rc2 permite a atacantes remotos causar una denegación de servicio (consumo de CPU) a través de un número grande del mismo método de autenticación en una solicitud, también conocido como "encadenamiento de autenticación."

A flaw was found in the keystone V3 API. An attacker could send a single request with the same authentication method multiple times, possibly leading to a denial of service due to generating excessive load with minimal requests. Only keystone setups with the V3 API enabled were affected by this issue.
