Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Microsoft PowerPoint 2002 SP3, 2003 SP3, and 2007 SP2; Office 2004 and 2008 for Mac; Open XML File Format Converter for Mac; and Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats SP2 make unspecified function calls during file parsing without proper handling of memory, which allows remote attackers to execute arbitrary code via a crafted PowerPoint document, aka "Presentation Memory Corruption RCE Vulnerability."

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

This is a memory corruption vulnerability in Microsoft PowerPoint's file parsing logic. When PowerPoint opens a crafted malicious .pptx file, it makes unspecified function calls during parsing without proper memory handling, leading to heap corruption that can be leveraged for remote code execution.

MitigationApply Microsoft security patches MS11-021, MS11-022, or MS11-023 (depending on affected product version). Until patched, avoid opening untrusted PowerPoint files and enable Protected View in Office.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check installed PowerPoint version on Windows
    Open Registry Editor and navigate to HKLM\SOFTWARE\Microsoft\Office\{version}\PowerPoint\InstallRoot, or run 'wmic product where "name like '%PowerPoint%'" get version,name' in Command Prompt
    Affected if The installed version matches 2002 (10.x), 2003 (11.x), 2007 (12.x), or for Mac 2004 (11.x) or 2008 (12.x)
  2. Check Microsoft Office version on Windows
    Open Registry Editor and navigate to HKLM\SOFTWARE\Microsoft\Office\{version}\Common\InstallRoot, or check Help > About Microsoft Office in any Office application
    Affected if The installed Office version matches 2004, 2007, or 2008 (for Mac) from the affected product list
  3. Check Microsoft Office Compatibility Pack version
    Go to Control Panel > Programs and Features, locate 'Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint File Formats', right-click and select 'Change' to see the version, or check registry at HKLM\SOFTWARE\Microsoft\Office\CompatibilityPack\InstallRoot
    Affected if Version is 2007 (12.x) specifically
  4. Check for Microsoft Open Xml File Format Converter
    Check installed programs list in Control Panel > Programs and Features for 'Microsoft Open XML File Format Converter' or check registry at HKLM\SOFTWARE\Microsoft\Office\Application Cleanup\OpenXmlFileFormatConverter
    Affected if The converter is installed (all versions are affected)
  5. Verify .pptx file handling capability
    Attempt to open any .pptx file in the installed PowerPoint application, or check file association for .pptx extension in Default Programs
    Affected if PowerPoint can open and parse .pptx files, which triggers the vulnerable code path

You are affected if any of the installed Microsoft Office, PowerPoint, Compatibility Pack, or Open XML File Format Converter versions match 2002, 2003, 2004, 2007, or 2008 and the application can open .pptx files.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply Microsoft security patches MS11-021, MS11-022, or MS11-023 (depending on affected product version). Until patched, avoid opening untrusted PowerPoint files and enable Protected View in Office.

Recommended fix High confidence

Microsoft 365 (recommended) or Office 2016/2019/2021

  1. 1. Identify the current Microsoft Office/PowerPoint version installed by opening any Office application, clicking Help, and viewing the About/Microsoft <App> information.
  2. 2. For PowerPoint 2002 (2002 SP3): Apply Microsoft Security Update MS11-036 (KB2547206) from https://docs.microsoft.com/en-us/security-updates/securitybulletins/2011/ms11-036
  3. 3. For PowerPoint 2003 (2003 SP3): Apply Microsoft Security Update MS11-036 (KB2535802) from the same bulletin
  4. 4. For PowerPoint 2007 (2007 SP2): Apply Microsoft Security Update MS11-036 (KB2519978) from the same bulletin
  5. 5. For Office 2004/2008 for Mac: Apply the respective Mac security updates from MS11-036
  6. 6. For Office Compatibility Pack 2007 (SP2): Apply Microsoft Security Update MS11-036 (KB2519978)
  7. 7. For Open XML File Format Converter for Mac: Apply the Mac security update from MS11-036
  8. 8. Alternatively, upgrade to a currently supported Microsoft Office version (Microsoft 365, Office 2016, 2019, or 2021) to receive ongoing security updates
Caveat Upgrading from Office 2004/2008 or PowerPoint 2002/2003/2007 may require migration to newer file formats and may have feature changes; legacy Mac converters are deprecated in favor of native Office for Mac support
