Microsoft Security Bulletin MS09-010 - Critical
Vulnerabilities in WordPad and Office Text Converters Could Allow Remote
Code Execution (960477)
Published: April 14, 2009
Version: 1.0
General Information
Executive Summary
This security update resolves two publicly disclosed vulnerabilities and
two privately reported vulnerabilities in Microsoft WordPad and Microsoft
Office text converters. The vulnerabilities could allow remote code
execution if a specially crafted file is opened in WordPad or Microsoft
Office Word. Do not open Microsoft Office, RTF, Write, or WordPerfect
files from untrusted sources using affected versions of WordPad or
Microsoft Office Word.
This security update is rated Critical for supported editions of Microsoft
Office Word 2000. This security update is also rated Important for
supported editions of Microsoft Office Word 2002; Microsoft Office
Converter Pack; and WordPad on all supported editions of Microsoft Windows
2000, Windows XP, and Windows Server 2003. For more information, see the
subsection, Affected and Non-Affected Software, in this section.
This security update addresses the vulnerabilities by modifying the way
that Microsoft Office Word and Office text converters handle opening
specially crafted Word 6.0, Windows Write, and WordPerfect documents. This
security update also addresses the vulnerabilities by implementing fixes
to WordPad and by preventing WordPad on affected platforms from opening
Word 6.0 and Windows Write files. For more information about the
vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for
the specific vulnerability entry under the next section, Vulnerability
Information.
Recommendation. Microsoft recommends that customers apply the update
immediately.
