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
Thus, this affects only systems with groff installed (all Linux and FreeBSD
systems, at least).
Umm, not quite. My 1976 (no, that's not a typo) nroff/troff manual has
.pi -- pipe output to program; .sy is also ancient, and probably there since
at least since 1977. My 1981 addendum also lists .! as another way to do
