Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
IrfanView 4.50 - 64bit with BabaCAD4Image plugin version 1.3 allows attackers to execute arbitrary code or cause a denial of service via a crafted .dwg file, related to a "User Mode Write AV near NULL starting at BabaCAD4Image!ShowPlugInOptions+0x000000000001ce82."

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The BabaCAD4Image plugin version 1.3 for IrfanView 4.50 64-bit contains a memory corruption vulnerability when parsing specially crafted .dwg CAD files. The bug manifests as a user-mode write access violation occurring near a NULL address at ShowPlugInOptions, indicating improper bounds checking or buffer handling during DWG file parsing that can be exploited for arbitrary code execution or denial of service.

MitigationAvoid opening untrusted or unverified .dwg files with the BabaCAD4Image plugin; disable or remove the plugin if no update is available from the vendor; consider using alternative CAD viewers for untrusted files.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify IrfanView version
    Check if IrfanView version 4.50 is installed. Look in the program files directory for IrfanView (usually C:\Program Files\IrfanView\i_view64.exe or C:\Program Files (x86)\IrfanView\i_view32.exe) and view the file properties to confirm version 4.50, or check the registry key HKEY_LOCAL_MACHINE\SOFTWARE\IrfanView\Version or HKEY_CURRENT_USER\Software\IrfanView for the installed version.
    Affected if IrfanView version 4.50 is installed
  2. Locate BabaCAD4Image plugin
    Check for the presence of the BabaCAD4Image plugin DLL in the IrfanView plugins directory. The plugin is typically located in C:\Program Files\IrfanView\Plugins\ or C:\Program Files (x86)\IrfanView\Plugins\ and should appear as Babacad4image.dll or similar naming convention. Check the file properties to confirm version 1.3.
    Affected if BabaCAD4Image plugin version 1.3 exists in the IrfanView plugins folder
  3. Confirm plugin is loaded
    Open IrfanView and navigate to Options > Properties/Settings > Plugins to see if the BabaCAD4Image plugin is listed as loaded and enabled. Alternatively, attempt to open a .dwg file via File > Open to see if IrfanView attempts to use the plugin.
    Affected if The BabaCAD4Image plugin appears enabled in the IrfanView plugins list or attempts to process .dwg files

A user is affected if they have IrfanView 4.50 installed with the BabaCAD4Image plugin version 1.3 present and enabled, and they open a specially crafted .dwg file.
