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.
