Re: Troff dangerous.

[John Robert LoVerso]

This isn't a problem with "troff" or any of it's varients.  Instead,
this is an exploit purely with "groff", the GNU reimplementation.  Troff
doesn't have the file stream or ".pso" requests; those are purely part
of groff.

Thus, this affects only systems with groff installed (all Linux and FreeBSD
systems, at least).
