Title:
  You can crash keystone or make the DB very slow by assigning many
  roles

Status in Keystone:
  Triaged
Status in OpenStack Security Advisory:
  Incomplete

Bug description:
  This is applicable for UUID and PKI tokens.

  Token table has extra column where we store role information.  It is a
  blob with 64K limit. Basically we can do the following to fill the
  BLOB

     Say user is U, and Project is P
     for i =1  to  1000 ( or any large number)
          role x = create role i  with some large name
          assign role x for user U and Project P
         create a project scoped token for user U
