Descriptions

OpenStack Identity (Keystone) Folsom, Grizzly 2013.1.3 and earlier, and Havana before havana-3 does not properly revoke user tokens when a tenant is disabled, which allows remote authenticated users to retain access via the token.

OpenStack Identity (Keystone) Folsom, Grizzly 2013.1.3 y anteriores, y Havana anterior havana-3 no revoca correctamente los tokens de usuario cuando un inquilino esta desactivado, lo que permite a los usuarios remotos autenticados conservan el acceso a través del token.

The openstack-keystone packages provide Keystone, a Python implementation of the OpenStack identity service API, which provides Identity, Token, Catalog, and Policy services. It was found that tokens issued to a tenant were not invalidated when that tenant was disabled in Keystone. This could allow users assigned to a disabled tenant to retain access to resources they should no longer be able to access. These updated packages have been upgraded to upstream version 2013.1.4, which provides a number of bug fixes over the previous version.
