Hi Volodymyr,
In the past, I met a code like this, which was using less then 2kb of codeGood job! :-)
to do that
Yes, once you get the buffer vulnerability you can
completely gain access to a system "IF" the Context
is Administrator. And best would be to insert itself
into kernel or much better to patch kernel code, replace
some driver, extend a driver that is safe with your code
and place it at the bottom of the stack...endless ways
to "fuck" a system and this techniques are not only bound
to windows systems as such most of the (novice) developers
think. this also works for Linux fine and all other OS'es
that have some kind of Ring 0-3 and Kernel Space!
Yes, a video file can contain very dangerous code and
thats why you have to work always with a restricted
account or limited access to system resources. The
best way to protect yourself!
@Volodymyr
Do you know whether this is true or not? Did he really break
that AACS? I ask this here because it came into my mind
while reading this post. If i remember it right, there was a
"public" piece of memory buffer holding the secure key in
plain text (very poor!) in a application working with AACS
Stuff,...i mean this:

And it is written in Java....*g*
The guy who broke this is "muslix64" and the guy who found
the genric gey is "arnezami",...

Kerem
