Microsoft Security Bulletin MS10-004 – Important
Vulnerabilities in Microsoft Office PowerPoint Could Allow Remote Code
Execution (975416)
Published: February 09, 2010
Version: 1.0
General Information
Executive Summary
This security update resolves six privately reported vulnerabilities in
Microsoft Office PowerPoint. The vulnerabilities could allow remote code
execution if a user opens a specially crafted PowerPoint file. An attacker
could then install programs; view, change, or delete data; or create new
accounts with full user rights. 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 Important for supported editions of Microsoft
Office PowerPoint 2002 and Microsoft Office PowerPoint 2003, and Microsoft
Office 2004 for Mac.
The security update addresses the vulnerabilities by changing the way that
Microsoft Office PowerPoint and Microsoft PowerPoint Viewer parse specially
crafted PowerPoint files.
Recommendation. Microsoft recommends that customers apply the update at the
earliest opportunity.
Known Issues. Microsoft Knowledge Base Article 975416 documents the
currently known issues that customers may experience when installing this
security update. The article also documents recommended solutions for these
issues. When currently known issues and recommended solutions pertain only
