CVE-2013-0282 OpenStack Keystone: EC2-style authentication accepts disabled user/tenants

Russell Bryant (email@example.com) reports:
Title: Keystone EC2-style authentication accepts disabled user/tenants
Reporter: Nathanael Burton (National Security Agency)
Affects: All versions
Nathanael Burton reported a vulnerability in EC2-style authentication
in Keystone. Keystone fails to check whether a user, tenant, or domain
is enabled before authenticating a user using the EC2 api.
Authenticated, but disabled users (or authenticated users in disabled
tenants or domains) could therefore retain access rights that were
thought removed. Only setups enabling EC2-style authentication are
affected. To disable EC2-style authentication to work around the
issue, remove the EC2 extension
(keystone.contrib.ec2:Ec2Extension.factory) from the keystone API
pipeline in keystone.conf.
See attached patches. Unless a flaw is discovered in them, these
patches will be merged to Keystone master (Grizzly), stable/folsom,
and stable/essex branches on the public disclosure date.
