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.
-
Confirm IrfanView installationLocate the IrfanView executable (typically in Program Files/IrfanView) and check its file properties to identify the installed version, or open IrfanView and navigate to Help > About to view the version informationAffected if The installed version is IrfanView 4.44 (32-bit)
-
Locate and identify the PDF pluginCheck for the presence of a PDF plugin file in the IrfanView Plugins directory (commonly named i_pdf.dll or similar PDF-related DLL in the Plugins folder)Affected if A PDF plugin is installed alongside IrfanView
-
Determine PDF plugin versionCheck the file properties of the PDF plugin DLL (right-click > Properties > Details) or attempt to load the plugin through IrfanView to view its version informationAffected if The PDF plugin version is 4.43
-
Verify 32-bit installationConfirm whether the IrfanView installation is the 32-bit version (check the executable name or file properties - 32-bit versions are typically labeled or the 64-bit version explicitly indicates '64')Affected if The installation is the 32-bit version of IrfanView 4.44 with PDF plugin 4.43
You are affected if IrfanView 4.44 (32-bit) with PDF plugin version 4.43 is installed and the PDF plugin is present and enabled, as the vulnerability triggers during PDF parsing.
