Vulnerability Note VU#468227

Microsoft Vista and Server 2008 vulnerable to memory corruption via saved search

Overview

Microsoft Windows Vista and Server 2008 contain a memory corruption vulnerability when saving a specially crafted search file. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.

I. Description

In Windows Vista and Server 2008, users can save searches as a search folder that is generated by a .search-ms XML file. Microsoft Windows fails to properly parse .search-ms files, which can result in memory corruption.

II. Impact

By convincing a user to save a specially crafted search specified by a .search-ms file, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system.

III. Solution

Apply an update

This vulnerability is addressed in Microsoft Security Bulletin MS08-075. This bulletin also includes several workarounds, including changing the file association for .search-ms files and denying the ability to save searches.
