Microsoft Security Bulletin MS10-088 - Important

Vulnerabilities in Microsoft PowerPoint Could Allow Remote Code Execution 
(2293386)

Version: 1.0

General Information

Executive Summary

This security update resolves two privately reported vulnerabilities in 
Microsoft Office that could allow remote code execution if a user opens a 
specially crafted PowerPoint file. An attacker who successfully exploited any 
of these vulnerabilities could take complete control of an affected system. 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 
PowerPoint 2002, Microsoft PowerPoint 2003, and Microsoft Office 2004 for Mac; 
and all supported versions of Microsoft PowerPoint Viewer. For more 
information, see the subsection, Affected and Non-Affected Software, in this
