Microsoft DirectX Media SDK FlashPix ActiveX Control Buffer Overflow

From Secunia (exploit below):

Description:
Krystian Kloskowski has discovered a vulnerability in DirectX Media SDK, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error in Live Picture Corporation’s DXSurface.LivePicture.FLashPix.1 (DXTLIPI.DLL) ActiveX control when handling the “SourceUrl” property. This can be exploited to cause a heap-based buffer overflow by assigning an overly long (greater than 1024 bytes) string to the affected property.

Successful exploitation allows execution of arbitrary code when e.g. a user visits a malicious website.

The vulnerability is confirmed in DirectX Media SDK version 6.0 including DXTLIPI.DLL version 6.0.2.827. Other versions and applications that use the affected ActiveX control may also be affected.

Solution:
Set the kill-bit for the affected ActiveX control.
