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.

The following was reported to the oss-security list:

Title: Keystone DoS through V3 API authentication chaining
Reporter: Abu Shohel Ahmed (Ericsson)
Products: Keystone
Versions: from 2013.1 to 2013.2.3

Description:
Abu Shohel Ahmed from Ericsson reported a vulnerability in Keystone V3
API authentication. By sending a single request with the same
authentication method multiple times, a remote attacker may generate
unwanted load on the Keystone host, potentially resulting in a Denial of
Service against a Keystone service. Only Keystone setups enabling V3 API
are affected.
