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
Buffer overflow in the FlashPix image converter in the graphics filters in Microsoft Office XP SP3 and Office Converter Pack allows remote attackers to execute arbitrary code via a crafted FlashPix image in an Office document, aka "FlashPix Image Converter Buffer Overflow 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 buffer overflow vulnerability in the FlashPix image converter component of Microsoft Office XP SP3 and Office Converter Pack graphics filters. Attackers exploit this by embedding a specially crafted FlashPix image file within an Office document; when opened, the malformed image triggers the overflow, allowing execution of arbitrary code with the user's privileges.

MitigationApply Microsoft Security Update MS10-087 (or subsequent relevant patches) to all affected Office XP and Office Converter Pack installations. Until patched, exercise caution with untrusted Office documents and disable the graphics filter handler if possible.

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 Office XP installation
    Check the Windows Registry for Microsoft Office XP installation under HKLM\SOFTWARE\Microsoft\Office\10.0\Common\InstallRoot or use Programs and Features to list installed Microsoft Office products.
    Affected if Microsoft Office XP (version 10.x) is listed as installed.
  2. Confirm Office XP Service Pack level
    Check registry key HKLM\SOFTWARE\Microsoft\Office\10.0\Common\InstallRoot for ServicePackLevel value or inspect installed updates via wmic qfe list.
    Affected if Service Pack 3 (SP3) is installed, as the vulnerability specifically affects Office XP SP3.
  3. Detect Office Converter Pack installation
    Check registry under HKLM\SOFTWARE\Microsoft\Office\Converter Pack or inspect Add/Remove Programs for 'Office Converter Pack' entry.
    Affected if Office Converter Pack of any version is installed.
  4. Locate FlashPix graphics filter component
    Search for the Fpx32.flt or fpx32.dll filter file in the Office graphics filters directory, typically found in C:\Program Files\Common Files\Microsoft Shared\Graphics\Filters or the Office10\Graphics\Filters folder.
    Affected if The FlashPix filter (Fpx32.flt or fpx32.dll) is present on the system.

The system is affected if either Office XP SP3 or any version of Office Converter Pack is installed and the FlashPix graphics filter component is present, allowing malformed FlashPix images embedded in Office documents to trigger the buffer overflow.
