Also, if any, this looks why the current industry sucks, putting little and shitty languages everywhere making PDF files very dangerous. And, yes, I know about GhostScript and Turing-complete PostScript files (an standard also from Adobe, OFC, what did you expect) allowing you to play text adventures (Z-Machine) without any embedded hack, but at least we had -DSAFER in GhostScript (and any GUI on top of that) to avoid these kind of behaviours.

Inb4 "this is the true hacker spirit", I know, yes, this is cool stuff and the true meaning of a hacker, but in the end I'd choose DJVU for a document format.
