Last year I demonstrated that it is possible to make a very small external
that gives root access to the whole pd process. This vulnerability only
affects Miller's pd, including pd-0.41-0test04 (which is the absolute
latest). I have fixed that problem during devel_0_39 and carried it into
the desiredata branch.
This problem is largely theoretical so far, as it requires an external to
play with the setuid/seteuid commands. I can't think of any external that
does that, except the small test that I made for the purpose of verifying
I haven't looked much for other possible breaches of root access.
