PC World has published an interesting article: http://www.pcworld.com/news/article/0,aid,119016,00.asp Short version: The Digital Rights Management for Windows Media files allows opening arbitrary urls in Internet Explorer. Impact: MSIE browser vulnerabilities can now be exploited through wma files, allowing virii, worms and other kinds of malware to spread through P2P networks. Happy new year! Cheers, SkyLined
