A critical new zero-day flaw involving Microsoft DirectShow's processing of QuickTime content is under attack, Microsoft reported today.
The flaw in the quartz.dll processor in the DirectShow platform affects Windows XP, 2000, and Server 2003. Windows Vista, Server 2008, and Windows 7 are not affected. Crooks can go after the hole even if you have Apple's QuickTime installed, according to Microsoft.
Also, while opening a malicious QuickTime file could trigger the flaw, it's not required. According to a Microsoft post (http://blogs.technet.com/msrc/archive/2009/05/28/microsoft-security-advisory-971778-vulnerability-in-microsoft-directshow-released.aspx) at its Security Response Center, "a browser-based vector is potentially accessible through any browser using media plug-ins that use DirectShow." So a drive-by-download--which can execute an attack in the background if you simply visit a malicious page--may be possible.
