Microsoft Internet Explorer fails to properly interpret layout positioning

Vulnerability Note VU#119180

Original Release Date: 2006-08-08 | Last Revised: 2006-08-17

Overview

Microsoft Internet Explorer fails to properly handle certain combinations of layout positioning. This can allow a remote attacker to execute arbitrary code on a vulnerable system.

Description

Microsoft Internet Explorer contains a vulnerability in the handling of certain combinations of layout positioning in an HTML document. When combined with Active Scripting, Internet Explorer may execute arbitrary code as a result of this vulnerability.

Impact

By convincing a user to view a specially crafted HTML document (e.g., a web page, an HTML email message, or an email attachment), an attacker could execute arbitrary code with the privileges of the user. The attacker could also cause Internet Explorer (or the program using the WebOC control) to crash.
