DESCRIPTION:
A security issue has been reported in OpenStack Keystone, which can
be exploited by malicious users to bypass certain security
restrictions.

The security issue is caused due to an error when granting or
revoking roles, which does not affect token validation for
pre-existing tokens and may result in tokens having an original set
of roles.

The security issue is reported in versions prior to 2012.1.3.

SOLUTION:
Update to version 2012.1.3.
