Description Kurt Seifried 2013-04-26 08:18:27 UTC 
Yaguang Tang reports:

concurrent requests with large POST body can crash the keystone process.

this can be used by Malicious and lead to DOS to Cloud Service Provider.

The OpenStack project has confirmed:

Concurrent Keystone POST requests with large body messages are held in memory 
without filtering or rate limiting, this can lead to resource exhaustion on 
the Keystone server.
