Microsoft warns of hole in Video ActiveX control

From CNET News.com: Microsoft on Monday warned of a vulnerability in its Video ActiveX Control that could allow an attacker to take control of a PC if the user visits a malicious Web site.

There have been limited attacks exploiting the hole, which affects Windows XP and Windows Server 2003, Microsoft said on its Security Response Center blog.

This is the second DirectShow security hole Microsoft has announced in the past few months. The company has yet to provide a security update for a vulnerability announced in May that involves the way DirectX handles QuickTime files.

Since there are no by-design uses for the ActiveX Control within Internet Explorer, Microsoft is recommending that users implement a workaround outlined in the security advisory. Customers can automatically implement the workaround by following the instructions under "Fix It For Me" in the Knowledge Base article for advisory number 972890 on the Microsoft support site.

Even though Windows Vista and Windows Server 2008 are not affected by the vulnerability, Microsoft is recommending that users of those products also use the workaround.
