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 CADImage Plugin DWG File Parsing Out-Of-Bounds Read Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of IrfanView CADImage Plugin. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of DWG files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-26107.

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 CADImage plugin in IrfanView fails to properly validate bounds when parsing DWG files, allowing an out-of-bounds read beyond allocated buffer boundaries. This memory access error can be exploited to achieve remote code execution in the context of the current process when a user opens a specially crafted malicious DWG file.

MitigationApply vendor patches for the CADImage plugin when released; until then, avoid opening untrusted DWG files and consider disabling the CADImage plugin if DWG viewing is not required.

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. Locate CADImage plugin DLL
    Search for files named cadimage.dll, CadImage.dll, or similar in the IrfanView installation directory, typically under a 'Plugins' or 'Plugins32' subfolder
    Affected if The CADImage plugin DLL exists in the IrfanView plugins directory
  2. Retrieve CADImage plugin version
    Right-click the CADImage DLL file, select Properties, then go to the Details tab to view the File Version or Product Version field
    Affected if The reported version number is lower than 15.0.0.8 (for example, 15.0.0.7, 14.x.x.x, etc.)
  3. Verify DWG file association with IrfanView
    Check if .dwg file extension is associated with IrfanView by opening IrfanView, going to Options > Properties/Settings > File types, or by right-clicking a DWG file in Windows Explorer and viewing the 'Opens with' program
    Affected if IrfanView is set as the default program for opening .dwg files, enabling the plugin to process DWG files automatically
  4. Confirm plugin is loaded by IrfanView
    Launch IrfanView and open any image file, then open Help > About Plugins to see a list of loaded plugins; the CADImage plugin should appear if it is active
    Affected if The CADImage plugin appears in the loaded plugins list, indicating it is active and capable of processing DWG files

You are affected if the CADImage plugin DLL (cadimage.dll or similar) is installed with IrfanView, handles DWG files, and its version is below 15.0.0.8.
