DIRECTSHOW, a framework for playing various media types, is being exploited in the wild in older versions of Windows, Microsoft has warned.

There is no patch for the vulnerability yet, but Microsoft has created a workaround registry script that you can download and run, at the Knowledge Base Article 971778.
