CVE reference:CVE-2006-6488


Description:
Will Dormann has discovered a vulnerability in ICONICS Gauge ActiveX, ICONICS Switch ActiveX, and ICONICS Vessel ActiveX, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to boundary errors in the Dialog Wrapper Module ActiveX control (DlgWrapper.dll) when handling the "DoModal()" method. This can be exploited to cause a stack-based buffer overflow by passing an overly long string as either the FileName or Filter argument.

Successful exploitation allows execution of arbitrary code when a user e.g. visits a malicious website.

The vulnerability is confirmed in ICONICS Vessel ActiveX 8.02.140 including DlgWrapper.dll 8.0.138.0. Other versions may also be affected.

Solution:
Update to DlgWrapper.dll 8.4.166.0 by applying the hotfix:
