Internet Pictures Corporation iPIX Image Well ActiveX controls contain buffer overflows

This info is from www.kb.cert.org (US- CERT)

The Internet Pictures Corporation "iPIX Image Well ActiveX" controls contain buffer overflows, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.

Internet Pictures Corporation has produced equipment and software to create 360 degree field-of-view images. The Internet Pictures Corporation iPIX Image Well ActiveX control, provided by iPIX-ImageWell-ipix.dll, contains several buffer overflow problems.

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.

Currently unaware of a practical solution to this problem. Internet Pictures Corporation has apparently filed for bankruptcy and does not appear to still be in business.

The vulnerable ActiveX controls can be disabled in Internet Explorer by setting the kill bit for the following CLSIDs:
    {ef8d9f2a-f641-4ef0-b2ec-3ba2be7c2960}
    {f7a05bac-9778-410a-9cde-bfbd4d5d2b7f}
Alternatively, the following text can be saved as a .REG file and imported to set the kill bit for these controls:
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{ef8d9f2a-f641-4ef0-b2ec-3ba2be7c2960}]
"Compatibility Flags"=dword:00000400

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{f7a05bac-9778-410a-9cde-bfbd4d5d2b7f}]
"Compatibility Flags"=dword:00000400
Disabling ActiveX controls in the Internet Zone (or any zone used by an attacker) appears to prevent exploitation of this and other ActiveX vulnerabilities.

Beware ...............
