Description Kurt Seifried 2012-09-27 18:07:27 UTC 
Jason Xu (yinyangxu) discovered several vulnerabilities in OpenStack 
Keystone token verification:

The first occurs in the API /v2.0/OS-KSADM/services and 
/v2.0/OS-KSADM/services/{service_id}, the second occurs in 
/v2.0/tenants/{tenant_id}/users/{user_id}/roles

In both cases the OpenStack Keystone code fails to check if the tokens are 
valid. These issues have been addressed by adding checks in the form of 
test_service_crud_requires_auth() and test_user_role_list_requires_auth().
