<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.
</p>
</description>
<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>
