Buffer overflow
 

George, can you elaborate more on this security enhancement on 4.0.5?

Implemented hacking shield to actively defend hacking attempts of buffer overflow.

I'd rather not to go into much detail, to give hint for hacker to around it or let our competitors replicate this feature. ;)

stack based buffer overflow should have been taken care of. And hacker will find very difficult to exploit any buffer overflow bug even they do find one.
