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. Verify PowerPoint is installed
    Open PowerPoint application, or check for PPT.EXE in typical Office installation paths (e.g., C:\Program Files\Microsoft Office\Office10\ or Office11\)
    Affected if PowerPoint is not found on the system - no vulnerability present
  2. Identify the PowerPoint version number
    In PowerPoint, go to Help > About Microsoft PowerPoint, or right-click PPT.EXE in the installation folder and select Properties > Details to view the Product Version
    Affected if Version shows 10.x (PowerPoint 2002) or 11.x (PowerPoint 2003)
  3. Confirm the Service Pack level
    In PowerPoint, go to Help > About Microsoft PowerPoint, or check the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\version\PowerPoint\InstallRoot for Service Pack information
    Affected if Service Pack 3 (SP3) is installed - this is the affected configuration

User is affected if PowerPoint 2002 SP3 or PowerPoint 2003 SP3 is installed and the system can open PowerPoint files, as this specific version and SP combination contains the buffer overflow vulnerability described in CVE-2011-1270

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

Apply Microsoft security updates for this vulnerability; avoid opening PowerPoint files from untrusted or unknown sources; keep PowerPoint updated to supported versions.

Recommended fix High confidence

Microsoft Office 2007 or later (PowerPoint 2007 and newer) which are not affected by this vulnerability

  1. Open Microsoft Update or check for updates via Help > Check for Updates in PowerPoint
  2. Locate and install the security update associated with Microsoft Security Bulletin MS11-036 (KB2545814 for PowerPoint 2002, KB2545815 for PowerPoint 2003)
  3. Restart PowerPoint after the update is installed
  4. Verify the update was installed by checking the installed updates via Control Panel > Programs and Features > View installed updates
Caveat PowerPoint 2002/2003 are no longer supported; upgrading to Office 2007+ may require file format compatibility considerations and license procurement
