Microsoft Windows ART image handling buffer overflow

Vulnerability Note VU#923236

Original Release Date: 2006-06-13 | Last Revised: 2006-06-14

Overview

Microsoft Windows ART image handling routines are vulnerable to a heap-based buffer overflow. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.

Description

ART Images

According to Microsoft Security Bulletin MS06-022:

ART is an image file format used by the America Online (AOL) client software. Windows also includes the library and Internet Explorer displays ART images.
The Problem

Microsoft Windows fails to properly handle malformed ART images allowing in a heap-based buffer overflow to occur. If a remote attacker can persuade a user to access specially crafted ART image, that attacker may be able to trigger the overflow.

Considerations

According to Microsoft Security Bulletin MS06-022:

Windows 2000 does not support AOL ART images by default. Windows 2000 is only affected if the Windows 2000 AOL Image Support Update has been installed.

For more information refer to Microsoft Security Bulletin MS06-022.

Impact

A remote, unauthenticated attacker may be able to execute arbitrary code. If the attacked user is running with administrative privileges, the attacker could take complete control of an affected system.
