http://secunia.com/advisories/product/20296/

DESCRIPTION:
Houssamix has discovered a vulnerability in the MW6 Technologies
Barcode ActiveX 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
Barcode.MW6Barcode.1 ActiveX control (Barcode.dll). This can be
exploited to cause a heap-based buffer overflow via an overly long
string assigned to the "Supplement" property.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in Barcode.dll version 3.0.0.1. Other
versions may also be affected.

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