Re: [Full-disclosure] AOL YGP Picture Editor YGPPicEdit.dll Multiple Buffer Overflows

I believe I have contributed greatly to the security community with my post
here. Not only have I denied another 0x41414141 hacker but I have also made
Valdis have to backtrack on his ( as usual) stupid post. I believe Valdis
and Billy O Reilly have alot in common. ( "
"I was wrong. I am not pleased about it at all and I think all Americans
should be concerned about this…What do you want me to do, go over and kiss
the camera?" ).

After some more analysis by Carsten Eiram @ Secunia, this is NOT
exploitable. I would like to apologize for the hasty post. SecurityFocus,
please update bid 27026 to reflect the fact that at most, this can just
crash the browser.

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.
