Microsoft Windows Vista Contacts Gadget vulnerability

Vulnerability Note VU#121024

Original Release Date: 2007-08-15 | Last Revised: 2007-08-15

Overview

The Windows Vista Contacts gadget contains a vulnerability that may allow an attacker to execute code.

Description

From Microsoft Security Bulletin MS07-048:

Gadgets are mini-applications designed to provide the user with information or utilities. Windows Vista treats gadgets similar to the way Windows Vista treats other executable code. Gadgets are written using HTML and script, but this HTML is not located on an arbitrary remote server as web pages are. HTML content in the Gadget is downloaded first as part of a package of resources and configuration files and then executed from the local computer. This download process is similar to applications (.exe files) downloaded from the Internet.

The Windows Vista Contacts gadget contains a code execution vulnerability. To exploit this vulnerability, an attacker would need to convince a user to download and add a specially crafted contact to the contacts gadget.

Impact

A remote, unauthenticated attacker may be able to execute arbitrary code, or create a denial-of-service condition.

Solution

Update
Microsoft has released update MS07-048 to address this issue.


Disable the Contacts gadget

Until updates can be applied, disabling the Contacts gadget will mitigate this vulnerability. To disable the Contacts gadget, see the workarounds section of Microsoft Security Bulletin MS07-048.
