CVE-2014-0105

El middleware auth_token en la librería del cliente Python de OpenStack para Keystone (también conocido como python-keystoneclient) anterior a 0.7.0 no consigue debidamente tokens de usuario de la memcache, lo cual permite a usuarios remotos autenticados ganar privilegios en circunstancias oportunistas a través de un gran número de peticiones, relacionado con una "interacción entre eventlet y python-memcached.".

Python-keystoneclient is a client library and a command line utility for interacting with the OpenStack Identity API. The OpenStack Identity auth_token middleware component handles the authentication of tokens with keystone. The gluster-swift component, provided by Red Hat Storage, requires the auth_token middleware. When using the auth_token middleware with the memcached token cache enabled, a token for a different identity could be returned. An authenticated user could use this flaw to escalate their privileges by making repeated requests that could eventually allow the user to acquire the administrator's identity. Note that only OpenStack Identity setups using auth_token with memcached were affected.
