Actually, I think the worst security problem I've seen is one I don't personally care to fix right now, but I guess I will soon. It's the fact that postscript is actually a language, one that's more general purpose in limitations than many people realize. Isn't that true? I think this means that my postscript interpreter (which is, for me, and I think for most, is ghostscript) should have some security controls on it, to limit postscript's direct access to local machine capabilities. I think that the options in gs for security are too little. It'd be pretty easy to write a really nasty worm. I remember laughing at my Windows friends, back when that Philappines worm hit, but we could get pretty easily hit on gs, or am I all wet? I don't much like pdf, but at least its not succeptible to such a thing, because pdf's not a general purpose language (not a language at all). Nobody's take advantage of it, but it'd be possible to write a general purpose docbook interpreter entirely in postscript. Wonder if modern gs limitations would allow such a big program? Sure would be convenient. > -Rek > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to > "freebsd-questions-unsubscribe@freebsd.org"
