Descriptions

OpenStack Keystone Essex (2012.1) and Folsom (2012.2) does not properly handle EC2 tokens when the user role has been removed from a tenant, which allows remote authenticated users to bypass intended authorization restrictions by leveraging a token for the removed user role.

OpenStack Keystone Essex (2012.1) and Folsom (2012.2) no controlan correctamente los token EC2 cuando la función de usuario se ha eliminado de un inquilino, lo que permite a usuarios autenticados remotamente eludir las restricciones previstas al aprovechar un token para la función de usuario eliminado.
