Hylafax is used on tiff files recieved from fax machines on the other end. Some malicious user might send invalid tiff files.

All of your other examples are reasonable, but this one is practically impossible, as the fax protocol does not transfer "a TIFF file" per se, but is an extremely narrowly defined protocol with extensive verification and handshaking. TIFF is only a convenient wrapper, created post facto, for the verified compressed multipage transmission. In other words, afaik, you can't insert "an arbitrary TIFF" in the sending end of the call and expect that to pop out the other end.

Except for faxes delivered as TIFF files via the Internet. Hylafax has a much narrower focus than the other packages mentioned.
