Newtone ImageKit is a set of ActiveX controls that provide image processing, scanning, and printing capabilities. The ActiveX controls provided by ImageKit contain several buffer overflow vulnerabilities.

The vulnerable ImageKit controls are included with the CASIO Photo Loader software, which comes with CASIO digital cameras. Other software may also include the vulnerable controls.

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.

Upgrade or patch

CASIO Photo Loader users should upgrade to Photo Loader 3.01.

Newtone ImageKit 5 users should upgrade to ImageKit 5 Fix 30 or later.
Newtone ImageKit 6 users should upgrade to ImageKit 6 Fix 41 or later.

Disable the vulnerable ImageKit ActiveX controls in Internet Explorer

The vulnerable ImageKit ActiveX controls can be disabled in Internet Explorer by setting the kill bit for the following CLSIDs:

{87CDBE22-FBF6-11D2-B1B0-00E0290EA3C9}
{EF2E3685-201D-11D3-B1B0-00E0290EA3C9}
{FF8676C3-11ED-11D3-B1B0-00E0290EA3C9}
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\{87CDBE22-FBF6-11D2-B1B0-00E0290EA3C9}]
"Compatibility Flags"=dword:00000400

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{EF2E3685-201D-11D3-B1B0-00E0290EA3C9}]
"Compatibility Flags"=dword:00000400

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{FF8676C3-11ED-11D3-B1B0-00E0290EA3C9}]
"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.
