Situation is worse. I was able to see

1. Source code itself (may expose bugs in software)
2. Data from other threads. For exaxmple on busy web server I see pieces 
of HTML other users are seeing. Think if they are watching their private 
e-mails or use internet banking.

What is good for attacker - this exploit does not crash server. Just 
"reload" and more data is coming. So try it on production server and you 
see how dangerous it might be. At least till now we got no crashing 
problems with it.
