Microsoft Security Bulletin MS09-023 - Moderate

Vulnerability in Windows Search Could Allow Information Disclosure (963093)

   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.

Affected Software

   Windows Search 4.0 on 
   Windows XP Service Pack 2 and 
   Windows XP Service Pack 3
   Windows Search 4.0 on 
   Windows XP Professional x64 Edition Service Pack 2
   Windows Search 4.0 on 
   Windows Server 2003 Service Pack 2
   Windows Search 4.0 on 
   Windows Server 2003 x64 Edition Service Pack 2

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.
