CRITICAL:

IMPACT:

WHERE:
>From remote

SOFTWARE:
ICONICS Gauge ActiveX 8.x
http://secunia.com/product/13098/

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:
