[OSSA 2012-014] Revoking a role does not affect existing tokens (CVE-2012-4413)
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 OpenStack Security Advisory: 2012-014 CVE: CVE-2012-4413 Date: September 12, 2012 Title: Revoking a role does not affect existing tokens Impact: High Reporter: Dolph Mathews (Rackspace) Products: Keystone Affects: Essex, Folsom Description: Dolph Mathews reported a vulnerability in Keystone. Granting and revoking roles from a user is not reflected upon token validation for pre-existing tokens. Pre-existing tokens continue to be valid for the original set of roles for the remainder of the token's lifespan, or until explicitly invalidated. This fix invalidates all tokens held by a user upon role grant/revoke to circumvent the issue. Folsom fix: http://github.com/openstack/keystone/commit/efb6b3fca0ba0ad768b3e803a3240430...
