Published: June 9, 2009
Version: 1.0
General Information
Executive Summary
This security update resolves a privately reported vulnerability in
Windows Search. The vulnerability could allow information disclosure if
a user performs a search that returns a specially crafted file as the
first result or if the user previews a specially crafted file from the
search results. By default, the Windows Search component is not
preinstalled on Microsoft Windows XP and Windows Server 2003. It is an
optional component available for download. Windows Search installed on
supported editions of Windows Vista and Windows Server 2008 is not
affected by this vulnerability.
This security update is rated Moderate for Windows Search installed on
all supported editions of Windows XP and Windows Server 2003. For more
information, see the subsection, Affected and Non-Affected Software, in
this section.
The security update addresses this vulnerability by modifying how
Windows Search restricts the environment within which scripts execute.

Vulnerability Information
Script Execution in Windows Search Vulnerability - CVE-2009-0239
An information disclosure vulnerability exists in Windows Search due to
the way file previews are generated. Attempts to exploit this
vulnerability require user interaction. An attacker who successfully
exploited this vulnerability could run a malicious HTML script that
could disclose information, forward user data to a third party, or
access any data on the affected systems that was accessible to the
logged-on user. Note that this vulnerability would not allow an attacker
to execute code or to elevate their user rights directly, but it could
be used to produce information that could be used to try to further
compromise the affected system.
