    <p>
    Kees Huijgen discovered an error when checking the credentials which
    can lead to a login without specifying a password. This only occurs
    when auto login is configured for at least one user and a password is
    required to shut down the machine.

  <impact type="high">
    <p>
    A local attacker could gain root privileges and execute arbitrary
    commands by logging in as root without specifying root's password.
    </p>
  </impact>
