Well, I can understand their concerns, without getting too deep into
the "movie thriller" plots. We just acquired an HP OfficeJet Pro 8500,
and the machine might as well be considered a full-fledged computer.
It's got a color touchscreen, a web server interface, a JetDirect
server, ethernet connections, USB connections and memory card slots.
It makes cheerful little sounds and shows animations. Through several
administrative interfaces, it has service software like mDNS and DHCP
that can be turned on or off. It reads photo cards, displays the
pictures, and offers to upload the pictures to a network share. I
wouldn't be surprised to learn that it was running a minimal Linux or
other OS. I could imagine a situation where a malformed file format
might cause a buffer overrun that could lead to compromising the
machine, from the photo card side. I'm not sure that the fax modem
could be similarly compromised, but it's worth a review.
