I morse upptäckte Symantec en bugg i Windows Messenger service.
Själva buggen upptäktes av Symantecs säkerhetsavdelning och den använder protokollet UDP (User Datagram Protocol)
Det farliga med UDPbuggen är att det är inte samma autentisering som på protokollet TCP och den tar emot overifierade filer vilket skapar ett allvarligt säkerhetshål.

"But we actually think that if this exploit is packaged into a worm, it could spread faster, quite a bit faster, than Slammer. Slammer had to infect each machine individually, but all it takes is one packet [of malicious code] to infect an entire network using this exploit. It's like the difference between talking one-on-one, and screaming out to a room full of people.
If I can exploit one single box on your network, I can exploit all of them,” Sa Huger på Symantec.
