Security updates for May 2009
On Tuesday, May 12th, 2009, Microsoft released 7 security updates for Office. The updates address security issues described in Microsoft Security Bulletin MS09-017: Vulnerabilities in Microsoft Office PowerPoint Could Allow Remote Code Execution (967340) (https://www.microsoft.com/technet/security/bulletin/ms09-017.mspx). Excerpt follows.
“This security update resolves a publicly disclosed vulnerability and several privately reported vulnerabilities in Microsoft Office PowerPoint 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 Critical for supported editions of Microsoft Office PowerPoint 2000. For supported editions of Microsoft Office PowerPoint 2002, Microsoft Office PowerPoint 2003, Microsoft Office PowerPoint 2007, Microsoft Office 2004 for Mac, and Microsoft Office 2008 for Mac; Open XML File Format Converter for Mac; all supported versions of PowerPoint Viewer, and Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats; Microsoft Works 8.5; and Microsoft Works 9.0, this security update is rated Important. For more information, see the subsection, Affected and Non-Affected Software.
The security update addresses the vulnerabilities by modifying the way that PowerPoint handles conditions that could cause memory corruption when opening specially crafted PowerPoint files. This update also addresses the vulnerabilities by preventing Microsoft Office PowerPoint 2000 and Microsoft Office PowerPoint 2002 from opening PowerPoint 4.0 native file formats. For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the Vulnerability Information section in Microsoft Security Bulletin MS09-017: Vulnerabilities in Microsoft Office PowerPoint Could Allow Remote Code Execution (967340) (https://www.microsoft.com/technet/security/bulletin/ms09-017.mspx).
This security update also addresses the vulnerability first described in Microsoft Security Advisory 969136 (https://www.microsoft.com/technet/security/advisory/969136.mspx).
