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
IrfanView FlashPix Plugin 4.3.4 0 has an 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 · moderate confidence

The IrfanView FlashPix plugin 4.3.4 contains an integer overflow vulnerability. Integer overflows in image parsing plugins typically occur when calculating buffer sizes or memory allocations based on image dimensions from malformed files, potentially leading to heap corruption and arbitrary code execution.

MitigationUpgrade IrfanView and its FlashPix plugin to the latest version. As a temporary measure, avoid opening untrusted FlashPix (.fpx) files with IrfanView.

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. Locate IrfanView installation
    Check common installation paths (e.g., C:\Program Files\IrfanView, C:\Program Files (x86)\IrfanView) or search for irfanview.exe
    Affected if IrfanView is not installed, the system is not affected by this specific plugin vulnerability
  2. Find the FlashPix plugin file
    Look for fpix.dll in the IrfanView plugins directory (usually <IrfanView_install_path>\plugins\)
    Affected if The fpix.dll file is not present, the FlashPix plugin is not installed and this CVE does not apply
  3. Determine the FlashPix plugin version
    Right-click fpix.dll, select Properties, then view the Details tab for File Version; alternatively use: dir fpix.dll /-N or a file version viewer tool
    Affected if The version is exactly 4.3.4.0 (the affected version)
  4. Check if .fpx file handling is enabled
    Open IrfanView, go to Options > Properties/Settings > Plugins or check file associations for .fpx files in Windows settings
    Affected if IrfanView is configured to open .fpx files (this is the attack vector that enables exploitation)

You are affected if IrfanView with FlashPix plugin version 4.3.4.0 is installed and configured to handle .fpx files
