Trend Micro researchers have found a Web-based attack that exploits a known vulnerability in Windows Media Player. The attack is not widespread at the moment, but it is possible that other attackers will start exploiting the same vulnerability in the near future. Microsoft released a security fix for it on Jan. 10, as part of its monthly patch cycle. The vulnerability affects Windows XP, Windows Server 2003, Windows Vista, and Windows Server 2008, but not Windows 7 or Windows Server Server 2008 R2. Users should always keep their operating systems and other software installed on their computers up to date.”]
