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 checksWork through these to decide whether this CVE applies to you.
-
Verify IrfanView installed versionCheck the installed IrfanView version through the application's Help > About dialog, or inspect the version property of the IrfanView executable fileAffected if The installed version is exactly 4.44 (32-bit)
-
Verify PDF plugin versionLocate the PDF plugin file (typically named something like PDF.dll or similar plugin file in the IrfanView plugins directory) and check its file version property, or check the plugin version through IrfanView's Plugins menu if availableAffected if The PDF plugin version is exactly 4.43
-
Confirm system architectureCheck if the installed IrfanView is the 32-bit variant by examining the program files directory path (typically in 'Program Files (x86)' for 32-bit apps on 64-bit Windows) or the executable propertiesAffected if IrfanView is the 32-bit version installed on the system
-
Check for PDF file handling capabilityVerify that the PDF plugin is loaded and functional by attempting to open a PDF file in IrfanView, or check if the PDF plugin DLL exists in the IrfanView plugins directoryAffected if The PDF plugin is present and IrfanView can open PDF files
A system is affected if it runs IrfanView version 4.44 (32-bit) with PDF plugin version 4.43 and uses the PDF viewing capability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataAvoid opening untrusted or unverified PDF files in IrfanView, and update the PDF plugin to the latest version when a patch becomes available from the vendor.
