DESCRIPTION:
Houssamix has discovered two vulnerabilities in the FlexCell Grid
ActiveX control, which can be exploited by malicious people to
overwrite arbitrary files.

The vulnerability is caused due to the FlexCell.Grid ActiveX control
(FlexCell.ocx) providing the insecure "SaveFile()" and
"ExportToXML()" methods. This can be exploited to corrupt arbitrary
files in the context of the currently logged-on user.

The vulnerabilities are confirmed in FlexCell.ocx version 5.7.0.2.
Other versions may also be affected.

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