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 4.50 64-bit is installedCheck the IrfanView installation directory (typically C:\Program Files\IrfanView or C:\Program Files (x86)\IrfanView) for i_view64.exe, then right-click the file, select Properties, and verify the File Version shows 4.50. Alternatively, run IrfanView and check Help > About IrfanView.Affected if The installed version is IrfanView 4.50 64-bit.
-
Locate the BabaCAD4Image pluginNavigate to the IrfanView plugins folder (usually C:\Program Files\IrfanView\Plugins or C:\Program Files (x86)\IrfanView\Plugins) and look for a file named BabaCAD4Image.dll or similar BabaCAD-related DLL.Affected if The BabaCAD4Image plugin DLL is present in the plugins folder.
-
Verify the plugin versionRight-click the BabaCAD4Image DLL file in the plugins folder, select Properties, and check the File Version or Product Version field. If version info is not directly available, right-click i_view64.exe and check its version details.Affected if The BabaCAD4Image plugin version is 1.3.
-
Confirm DWG file handling is enabledIn IrfanView, go to Options > Properties/Settings > Plugins, or check if .dwg files can be opened by attempting to open a DWG file directly. If IrfanView loads the BabaCAD4Image plugin for DWG files, the vulnerability is reachable.Affected if The BabaCAD4Image plugin is enabled and IrfanView attempts to render DWG files using it.
You are affected if IrfanView 4.50 64-bit is installed with the BabaCAD4Image plugin version 1.3 present and the plugin is enabled for handling DWG files.
