Package        : majordomo
Problem type   : local exploit
Debian-specific: no

The majordomo package as shipped in the non-free section accompanying
Debian GNU/Linux 2.1/slink allows any local user to trick majordomo into
executing arbitrary code or to create or write files as the majordomo user
anywhere on the filesystem.

This is a documented issue and the advised work around it to either have
no untrusted users on a system running majordomo or to use a setuid
wrapper that the MTA delivery agent can run.
suboptimal solution.

We feel that those options are not a good solution, but unfortunately the
majordomo license does not allow us to fix these problems and distribute a
fixed version. As a result we have decided to remove majordomo from our
archives.

If you are using majordomo we recommend that you replace it with one
of the many other mailing-list tools available such as fml, mailman
or smartlist.
