Microsoft Windows ART image handling buffer overflow

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.
