I note that this has been added to the Vulnerabilities Database on
www.securityfocus.org (#1030) with the following solution:

> The system.com program should be removed from the dosemu heirarchy.

I don't think this is adequate.  system.com is a fairly short file
(300 bytes), and if a user has any way to create files inside the
dosemu hierarchy (as they probably do, because otherwise dosemu is of
limited value), they can easily re-create it.

Correct fixes are listed at
http://www.dosemu.org/docs/README/0.98/README-3.html , the URL
referenced before.  Such as setting secure mode in the configuration
files.

(Note that I haven't tested this as I can't reproduce the
vulnerability with my current dosemu configuration.)
