TITLE:
Microsoft DirectX Media SDK FlashPix ActiveX Control Buffer Overflow

SECUNIA ADVISORY ID:
SA26426

VERIFY ADVISORY:
http://secunia.com/advisories/26426/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Microsoft DirectX Media SDK 6.x
http://secunia.com/product/15264/

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 buffer overflow by assigning an overly long (around 1044
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.
