General Information
Executive Summary
This security update resolves a privately reported vulnerability in the
Unicode Scripts Processor. The vulnerability could allow remote code execution
if a user viewed a specially crafted document or Web page with an application
that supports embedded OpenType fonts. An attacker who successfully exploited
this vulnerability could gain the same user rights as the local user. Users
whose accounts are configured to have fewer user rights on the system could be
less impacted than users who operate with administrative user rights.
This security update is rated Critical for all supported editions of Windows
XP, Windows Server 2003, Windows Vista, and Windows Server 2008, and Important
for Microsoft Office XP, Microsoft Office 2003, and Microsoft Office 2007. For
more information, see the subsection, Affected and Non-Affected Software, in
this section.
The security update addresses the vulnerability by correcting the way that
Windows parses specific characteristics of OpenType fonts. For more
information about the vulnerability, see the Frequently Asked Questions (FAQ)
subsection for the specific vulnerability entry under the next section,
