|
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.

<workaround>
