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.
-
Locate IrfanView installationCheck for IrfanView in typical installation paths: C:\Program Files\IrfanView or C:\Program Files (x86)\IrfanView. Look for i_view32.exe or i_view64.exe.Affected if IrfanView is installed in one of these locations
-
Check IrfanView executable versionRight-click the IrfanView executable (i_view32.exe or i_view64.exe), select Properties, and view the Version tab to find the product version.Affected if The version shown is 4.44 (the affected version listed in the CVE data)
-
Locate PDF plugin fileNavigate to the IrfanView plugins folder (usually C:\Program Files\IrfanView\plugins or within the main IrfanView folder) and locate PDF.dll.Affected if PDF.dll exists in the plugins directory
-
Check PDF plugin versionRight-click PDF.dll, select Properties, and view the Version tab to find the file version or product version.Affected if The version is 4.43 (the specific affected version for the PDF plugin)
-
Confirm plugin would be loadedVerify that the PDF.dll file is present and not renamed or disabled. IrfanView automatically loads plugins from the plugins folder when parsing PDF files.Affected if PDF.dll is present and the user opens a PDF file with IrfanView
If IrfanView version 4.44 or PDF plugin version 4.43 is detected and the PDF plugin is present, the environment is affected by this vulnerability when processing untrusted PDF files.

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 dataUpdate IrfanView and its PDF plugin to patched versions that address this vulnerability. Until then, avoid opening untrusted or unexpected PDF files with IrfanView.
