IBM Access Support eGatherer ActiveX control buffer overflow

Vulnerability Note VU#380277

Original Release Date: 2006-09-08 | Last Revised: 2007-03-08


The IBM Access Support eGatherer ActiveX control contains a buffer overflow vulnerability, which may allow a remote unauthenticated attacker to execute arbitrary code on a vulnerable system.


The IBM Access Support eGatherer ActiveX control has the ability to collect system information, such as make, model, serial number, OS version, etc. This control is available on the IBM / Lenovo web site, and also may come pre-installed on IBM and Lenovo computer systems. This control contains a buffer overflow vulnerability.


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.

This vulnerability is addressed in version 3.20.0284.0 of the eGatherer ActiveX control.
