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.
-
Check installed IrfanView versionOpen IrfanView and go to Help > About, or check the program's file properties (usually in C:\Program Files\IrfanView\i_view32.exe or C:\Program Files (x86)\IrfanView\i_view32.exe). Compare the version to 4.44.Affected if IrfanView version is exactly 4.44 (32-bit installation)
-
Check FPX plugin versionOpen IrfanView and go to Help > About > Plugins, or examine the FPX plugin file (typically fpix.dll in the IrfanView plugins folder). Compare the version to 4.46.Affected if FPX plugin version is exactly 4.46
-
Confirm FPX plugin is loadedIn IrfanView, go to Options > Properties/Settings > Plugins. Verify that the FPX (FlashPix) plugin is present and enabled in the plugin list.Affected if FPX plugin is present and enabled in IrfanView
-
Verify 32-bit architectureCheck if the IrfanView installation is the 32-bit version. This can be confirmed by checking the file properties of i_view32.exe or checking the installation path (32-bit is typically in C:\Program Files (x86)\IrfanView\).Affected if Running 32-bit version of IrfanView 4.44 with FPX plugin 4.46
The system is affected if IrfanView 4.44 (32-bit) with FPX plugin version 4.46 is installed and the FPX plugin is enabled, allowing specially crafted .fpx files to trigger the memory corruption.

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 the FPX plugin to versions that include the security fix; avoid opening untrusted .fpx files from unknown sources.
