Vulnerability Note VU#848873

iseemedia / Roxio / MGI Software LPViewer ActiveX control stack buffer overflows

Original Release date: 06 Oct 2008 | Last revised: 13 Apr 2009


The iseemedia LPViewer ActiveX control contains multiple stack buffer overflows, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.


The iseemedia LPViewer ActiveX control, which is provided by the file LPControl.dll, is a component that was created by MGI Software. It was then acquired by Roxio, and then iseemedia after that. The LPViewer ActiveX control contains stack buffer overflows in the url(), toolbar(), and enableZoomPastMax() methods.


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 Internet Explorer (or the program using the WebBrowser control) to crash.


We are currently unaware of a practical solution to this problem. Please consider the following workarounds:

Disable the LPViewer ActiveX control in Internet Explorer

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

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\{3F0EECCE-E138-11D1-8712-0060083D83F5}]
    "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.
