Microsoft WMF memory corruption vulnerability

Vulnerability Note VU#312956

Original Release Date: 2006-02-09 | Last Revised: 2006-02-14

Overview

Microsoft applications fail to properly handle Windows Metafile (WMF) images potentially allowing a remote attacker to execute arbitrary code on a vulnerable system.

Description

The Microsoft Windows Graphics Rendering Engine supports a number of image formats including WMF images. Windows WMF processing routines do not properly handle WMF images. This may allow a remote attacker to manipulate memory management routines resulting in a buffer overflow. Note that WMF processing is used in many Windows programs including Internet Explorer and Outlook.

For more information, including a list of affected versions of Internet Explorer, please see Microsoft Security Advisory 913333 and Microsoft Security Bulletin MS06-004.

Impact

By persuading a user to open a specially crafted WMF image file, an attacker may be able to execute arbitrary code with the privileges of the user.

Solution

This issue is corrected in Internet Explorer 6 Service Pack 1. In addition, Microsoft Security Bulletin MS06-004 contains a cumulative update to correct this vulnerability.

Do not accept WMF files from untrusted sources


By only accessing WMF image files from trusted or known sources, the chances of exploitation are reduced.
