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 IrfanView version
    Open IrfanView, go to Help > About, or right-click irfanview.exe and select Properties > Details to view the File Version
    Affected if The version is exactly 4.44 (32-bit)
  2. Check FPX plugin version

    Affected if The FPX plugin version is exactly 4.46
  3. Verify FPX plugin is loaded
    Open IrfanView and try to open a .fpx file, or check if fpx.dll exists in the plugins directory (typically C:\Program Files\IrfanView\Plugins\)
    Affected if The FPX plugin (fpx.dll) is present and IrfanView can load .fpx files
  4. Confirm 32-bit installation
    In IrfanView, go to Help > About or check the program directory name - 32-bit versions are typically installed in 'C:\Program Files (x86)\IrfanView\'
    Affected if The installed IrfanView is the 32-bit version

You are affected only if you have IrfanView 4.44 (32-bit) specifically with FPX plugin version 4.46, and the FPX plugin is installed and able to process .fpx files.
