                Mandrake Linux Security Update Advisory
______________________________________________________________________

Package name:           webmin
Advisory ID:            MDKSA-2003:025
Date:                   February 26th, 2003

Affected versions:      7.2, 8.0, 8.1, 8.2, 9.0,
                        Single Network Firewall 7.2
______________________________________________________________________

Problem Description:

 A vulnerability was discovered in webmin by Cintia M. Imanishi, in the
 miniserv.pl program, which is the core server of webmin.  This
 vulnerability allows an attacker to spoof a session ID by including
 special metacharacters in the BASE64 encoding string used during the
 authentication process.  This could allow an attacker to gain full
 administrative access to webmin.
 
 MandrakeSoft encourages all users to upgrade immediately.

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:

  https://www.mandrakesecure.net/RPM-GPG-KEYS

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

                Mandrake Linux Security Update Advisory
______________________________________________________________________

Package name:           shadow-utils
Advisory ID:            MDKSA-2003:026
Date:                   February 26th, 2003

Affected versions:      8.1, 8.2, 9.0, Multi Network Firewall 8.2
______________________________________________________________________

Problem Description:

 The shadow-utils package contains the tool useradd, which is used to 
 create or update new user information.  When useradd creates an
 account, it would create it with improper permissions; instead of
 having it owned by the group mail, it would be owned by the user's
 primary group.  If this is a shared group (ie. "users"), then all
 members of the shared group would be able to obtain access to the
 mail spools of other members of the same group.  A patch to useradd
 has been applied to correct this problem.
