                Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name:           usermode
Advisory ID:            MDKSA-2003:031
Date:                   March 12th, 2003

Affected versions:      8.1, 8.2, 9.0, Corporate Server 2.1,
                        Multi Network Firewall 8.2
________________________________________________________________________

Problem Description:

 The /usr/bin/shutdown command that comes with the usermode package can
 be executed by local users to shutdown all running processes and drop
 into a root shell.  This command is not really needed to shutdown a
 system, so it has been removed and all users are encouraged to upgrade.
 Please note that the user must have local console access in order to
 obtain a root shell in this fashion.

Please verify the update prior to upgrading to ensure the integrity of
the downloaded package.  You can do this with the command:

All packages are signed by MandrakeSoft for security.  You can obtain
the GPG public key of the Mandrake Linux Security Team from:
