he said me offline around 52000 chars , and you do not need to press
ok to trigger it, its supposed to occur when do you copy paste the
chars within the area, however here nothing happen on xp sp2 en +
firefox 1.5 , I can just see my AAA buffer replaced by a blank buffer
once I paste it in the box..

Well if you look at the fact there is no title on titlebar and the
fact the active tab is Untitled, I'd hazard to guess its something he
manually entered into the address bar, and so we don't even know if
this is exploitable by clicking a link or whatnot.

Not exactly sure why this was posted if no details are provided.
Anything else for us Sumit?

Dear Sumit,

Could you tell me how you exploited this buffer
overflow issue in Firefox so I can try and reproduce
it? I notice a lot of A's in your address bar but I'm
not sure whether that's it and if so, how many A's are
used.

Regards,

Lise

Hi,
The Windows display manager crashes when a BOF is
attempted on a mozilla
firefox.
This has different results on different windows
machine.
In Windows XP only the display manager crashes ,
whereas on a Windows 2000
server the BSOD(Blue screen of death )appears and
the system hangs.
I am using Firefox 1.0.6. I think that the bug is in
the display driver and
not with firefox. Kindly find a screen shot attached
with this email.

Thanks
Sumit
