Media Technology Group CDPass ActiveX control stack buffer overflows

Vulnerability Note VU#933353

Original Release Date: 2007-05-29 | Last Revised: 2007-05-31

Overview

The Media Technology Group CDPass ActiveX control contains several stack buffer overflows, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.

Description

Media Technology Group CDPass is software that provides bonus content for music CDs and DVDs. CDPass is an ActiveX control, which is provided by the file CDPass.dll. The CDPass ActiveX control contains several stack buffer overflows.

Impact

By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code with the privileges of the user. The attacker could also cause the web browser to crash.

Solution

Apply an update

This issue has been addressed in the CDPass ActiveX control version 1,0,0,14. To update, close all Internet Explorer windows. Go to %windir%\downloaded program files . Right click on CDPass Class and select update. If the CDPass ActiveX control is not updated to version 1,0,0,14, please consider the following workarounds


Disable the CDPass ActiveX control in Internet Explorer

The vulnerable ActiveX control can be disabled in Internet Explorer by setting the kill bit for the following CLSID:

{46C66BBD-E667-4dad-9682-58050E7C9FDC}
More information about how to set the kill bit is available in Microsoft Support Document 240797. Alternatively, the following text can be saved as a .REG file and imported to set the kill bit for this control:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{46C66BBD-E667-4dad-9682-58050E7C9FDC}]
"Compatibility Flags"=dword:00000400
Disable ActiveX

Disabling ActiveX controls in the Internet Zone (or any zone used by an attacker) appears to prevent exploitation of this and other ActiveX vulnerabilities. Instructions for disabling ActiveX in the Internet Zone can be found in the "Securing Your Web Browser" document.
