Overflowing an interactive app

[Steven Micallef <steven.micallef () world net>]

Hi all,

I'm trying to write a buffer overflow for an application that prompts the
user for input. Upon supplying the (over)lengthy input, the app segfaults.

My question is, what method would I use in my exploit to supply the overflow
string? I think using popen() and then fprintf() is the best way to do this,
but I'm new to this, so I was hoping for some suggestions.

Thanks,

Steve.
