openstack-keystone: two authentication bypass flaws

Package(s):openstack-keystone CVE #(s):CVE-2012-4456 CVE-2012-4457
Created:October 4, 2012 Updated:October 10, 2012
Description:

From the Red Hat Bugzilla entries [1, 2]:

CVE-2012-4456: Jason Xu 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().

CVE-2012-4457: Token authentication for a user belonging to a disable tenant should not be allowed.
