Re: [Full-disclosure] Sendmail/Postfix FORWARD Remote Exploit

["Joey Mengele" <joey.mengele@xxxxxxxxxxxx>]

Dead Fred Diggler,

You are not as much of an expert as you may have thought. Any 
foolish teenager can break software, but it takes a computer 
science degree to design software. For example, I have found a 
design flaw vulnerability (DFV) in your exploit. By passing a 
specially crafted argument to the program, an attacker can execute 
arbitrary code with Diggler privileges.

I have also uncovered several race conditions. If one executes the 
command 'pkill -11' on the program, for example, memory corruption 
seems to occur, and most modern operating systems output the buffer 
overflow code:

Segmentation fault

I hope you consult with experts before being so hasty to post your 
attempt at a technical rant. LOLOL.
