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 executable version
    Open File Explorer, navigate to the IrfanView installation directory (commonly C:\Program Files\IrfanView or C:\Program Files (x86)\IrfanView), right-click on i_view32.exe (the 32-bit executable), select Properties, and view the version number on the Details tab
    Affected if The version shown is 4.44 exactly
  2. Check PDF plugin version
    In the IrfanView installation directory, locate the PDF plugin file (commonly named PDF.dll or PDF.x86). Right-click on the file, select Properties, and check the version number on the Details tab
    Affected if The PDF plugin version is 4.43
  3. Verify 32-bit IrfanView is in use
    Confirm that i_view32.exe exists and is the primary executable being used (rather than i_view64.exe for 64-bit)
    Affected if The i_view32.exe (32-bit) executable is being used to run IrfanView with the vulnerable PDF plugin
  4. Confirm PDF plugin is installed
    Check the IrfanView installation directory for the presence of PDF plugin files (PDF.dll or similar)
    Affected if The PDF plugin DLL file is present in the IrfanView installation folder

A user is affected if they are running IrfanView version 4.44 (32-bit) with PDF plugin version 4.43 specifically, as this is the exact vulnerable configuration.
