DESCRIPTION:
rgod has discovered a vulnerability in RTSP MPEG4 SP Control, which
can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error in the
RtspVaPgCtrl Class ActiveX control when handling strings assigned to
the "Url" property. This can be exploited to cause a stack-based
buffer overflow by assigning an overly long string to the affected
property.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in RtspVapgDecoder.dll version
1.1.0.29 and reported in RtspVapgDecoderNew.dll version 2.0.0.39.
Other versions may also be affected.

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