            Caldera International, Inc.  Security Advisory

Subject: UnixWare 7.1.1 Open UNIX 8.0.0 : command line
buffer overflow in ndcfg
Advisory number: CSSA-2002-SCO.36
Issue date: 2002 August 21
Cross reference:

1. Problem Description

    The ndcfg command raises its privileges with the security
    subsystem (as opposed to being setuid), and has a buffer
    overlow in its command line processing. This could allow a
    malicious user to run code of their choice with raised
    privileges.
   

2. Vulnerable Supported Versions

    System                          Binaries
   

    UnixWare 7.1.1                  /usr/lib/netcfg/bin/ndcfg
    Open UNIX 8.0.0                 /usr/lib/netcfg/bin/ndcfg

3. Solution

    The proper solution is to install the latest packages.
