Intuit QuickBooks Online Edition ActiveX control stack buffer overflows

Vulnerability Note VU#907481

Original Release Date: 2007-09-05 | Last Revised: 2009-04-13

Overview

The Intuit QuickBooks Online Edition ActiveX control contains multiple stack buffer overflows, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.

Description

Intuit QuickBooks Online Edition is a version of QuickBooks that functions within Internet Explorer as an ActiveX control. This ActiveX control contains multiple stack buffer overflow vulnerabilities, which can allow an overwrite of the process Structured Exception Handler (SEH).

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

Apply an update

This issue is addressed in version 10 of the QuickBooks Online Edition ActiveX control. The fixed version of the QuickBooks Online Edition ActiveX control can be installed from the QuickBooks Online Edition web site.

The vulnerable ActiveX controls are also disabled in Microsoft Security Bulletin MS07-069.
