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
Integer overflow in the PICT image converter in the graphics filters in Microsoft Office XP SP3, Office 2003 SP3, and Office Converter Pack allows remote attackers to execute arbitrary code via a crafted PICT image in an Office document, aka "PICT Image Converter Integer 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

Integer overflow in the PICT image converter graphics filter allows remote code execution when users open Office documents containing specially crafted PICT images. The overflow enables attackers to execute arbitrary code via the malformed image data.

MitigationApply Microsoft security update MS10-105 to patch the affected Office installations (XP SP3, 2003 SP3, Converter Pack), and warn users against opening untrusted Office documents.

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. Identify installed Microsoft Office version
    Open Microsoft Word/Excel/PowerPoint, go to Help > About Microsoft Office [App] or check Programs and Features for Microsoft Office entries. Note the exact version number (e.g., Office 2003, Office XP).
    Affected if The installed version is Microsoft Office 2003 or Microsoft Office XP (any Service Pack level).
  2. Check for Microsoft Office Converter Pack installation
    Open Control Panel > Programs and Features and look for 'Microsoft Office Converter Pack' in the installed programs list.
    Affected if Microsoft Office Converter Pack is installed (any version).
  3. Verify presence of graphics filters including PICT converter
    Search for graphics filter files in the Office installation directory (typically in Program Files\Microsoft Office\OfficeXX\Graphics or similar paths). Look for filter files related to PICT image format conversion.
    Affected if PICT graphics filter component is present and loaded by Office applications.
  4. Check for unpatched state via installed updates
    Open Windows Update or check Add/Remove Programs for security update MS10-105 or verify that the specific patch for this CVE has not been installed.
    Affected if Security update MS10-105 has not been installed, leaving the PICT converter vulnerable.

A user is affected if they have Microsoft Office 2003, Office XP, or Office Converter Pack installed AND the PICT image converter graphics filter is present AND security update MS10-105 has not been applied.

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

Apply Microsoft security update MS10-105 to patch the affected Office installations (XP SP3, 2003 SP3, Converter Pack), and warn users against opening untrusted Office documents.

Recommended fix High confidence

Microsoft 365 Apps or Office 2019/2016 (supported versions with active security updates)

  1. Upgrade from Office XP SP3 or Office 2003 SP3 to a currently supported Microsoft Office version (such as Microsoft 365 Apps or Office 2019/2016)
  2. Ensure the upgraded Office installation receives current security updates
  3. If upgrading is not immediately feasible, remove or disable the PICT image converter add-in (graphics filters) as a temporary mitigation
  4. Do not open untrusted PICT image files received via email or downloaded from untrusted sources
  5. Implement application whitelisting to prevent execution of unknown binaries
Caveat Office XP and 2003 are end-of-support; upgrading requires migration of documents, macros, and potentially training for new interface; some legacy features may not be available in newer versions
