This is an extremely serious concern for security-concious
installations: how do they know that a bogus Helvetica hasn't been
loaded into their printer which works fine, except when asked to print
(Top Secret), in which case it prints (Unclassified)? Can any PostScript
expert out there guarantee that their Helvetica is correct?

Damage to disks is a possibility, and would be the act of a spiteful
hacker; damage to printed output is a very real reason why someone might
want to write a PostScript trojan horse in order to steal information.
