Retro64 / Miniclip CR64Loader ActiveX control buffer overflow

Original Release date: 01 Sep 2006 | Last revised: 07 Sep 2006

Overview

The Retro64 / Miniclip CR64Loader ActiveX control contains a buffer overflow vulnerability. This may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.

Description

The CR64Loader Object is an ActiveX control developed by Retro64. The web sites retro64.com and miniclip.com have used this ActiveX control to provide online games. This ActiveX control, which has a CLSID of {288C5F13-7E52-4ADA-A32E-F5BF9D125F99}, contains a buffer overflow vulnerability. Although the ActiveX control is no longer in use by either retro64.com or miniclip.com, any system that has used certain pages of these web sites in the past may be vulnerable.

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

Solution

Disable the CR64Loader ActiveX control

The CR64Loader ActiveX control can be disabled by setting the kill bit for the following CLSID:

    {288C5F13-7E52-4ADA-A32E-F5BF9D125F99}
More information about how to set the kill bit is available in Microsoft Support Document 240797.

Disable ActiveX


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