Mandrake Linux Advisory: usermode

Mar 12, 2003, 23:27 (0 Talkback[s])

______________________________________________________________________

                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.

To upgrade automatically, use MandrakeUpdate.  The verification of md5
checksums and GPG signatures is performed automatically for you.

If you want to upgrade manually, download the updated package from one
of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm".  A list of
FTP mirrors can be obtained from:

  http://www.mandrakesecure.net/en/ftp.php

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

  rpm --checksig <filename>

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

Please be aware that sometimes it takes the mirrors a few hours to
update.
