Vulnerability Development: Integer overflows

[<integer () hushmail com>]

Hey all,

I've been working on Gera's InsecureProgramming challenges and I stumped.
 Regarding n1.c, the integer overflows, is this exploitable on Linux/x86?
 I can cause a signedness error, but that's a huge amount of memory to
write and it SEGVs at the top of the stack.

Any help would been very much appreiciated.

Thanks,
