DESCRIPTION:
Houssamix has discovered two vulnerabilities in MetaProducts
MetaTreeX Control, which can be exploited by malicious people to
overwrite arbitrary files and compromise a user's system.

1) The SaveToBMP.MetaTreeX ActiveX control (MTXControl.OCX) contains
the insecure "SaveToBMP()" method. This can be exploited to corrupt
arbitrary files in the context of the currently logged-on user.

2) The SaveToBMP.MetaTreeX ActiveX control (MTXControl.OCX) contains
the insecure "SaveToFile()" method. This can be exploited to
overwrite arbitrary files in the context of the currently logged-on
user.

Successful exploitation of this vulnerability allows execution of
arbitrary code.

The vulnerabilities are confirmed in MTXControl.OCX version
1.5.0.100. Other versions may also be affected.

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