I'm not sure about dumping core, but given enough time with the proper
tools one could disassemble the executable, yes.

If it's going to run on the client pc, assuming it is actually running on
the client pc, the firewall becomes a moot point... However, if your
doing something like vnc, and it's not actually running on the client,
and the client has no direct access to the program, then you could say
it's fairly safe from being cracked/examined, yes.

The goal isn't to crash the program if at all possible, the goal or idea
rather is to trace the programs calls as it runs.
