How does a bunch of 'A's prove something is exploitable?
If a bunch of A's causes the EIP to end up as x'41414141', it's 95% of the
way to being an exploit. If it gets you some *other* crash, it's probably
at least 30% to 40% of the way to an exploit.
Go back and read the analysis of the NTP buffer overflow from a number of years
back. Truly a classic - they managed to leverage a *one byte* overflow into
a complete and total rooting of the box.
