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 DXF File Parsing Out-Of-Bounds Write 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 DXF files. The issue results from the lack of proper validation of user-supplied data, which can result in a write 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-26084.

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

An out-of-bounds write vulnerability exists in the IrfanView CADImage Plugin's DXF file parser due to insufficient validation of user-supplied data. The flaw allows writing past the end of an allocated buffer during DXF parsing, enabling remote code execution in the context of the current process when a user opens a malicious DXF file.

MitigationApply the vendor patch for the CADImage plugin when available. Until then, avoid opening untrusted DXF files and consider disabling or removing the CADImage plugin if DXF 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 the CADImage plugin file
    Search the IrfanView installation directory (commonly C:\Program Files\IrfanView or C:\Program Files (x86)\IrfanView) for plugin files related to CAD or DXF support, typically named CadImage.dll, CADImage.idf, or similar CADImage plugin files.
    Affected if The CADImage plugin file exists in the IrfanView plugins directory.
  2. Determine the CADImage plugin version
    Right-click the CADImage plugin file, select Properties, and check the File Version or Product Version field in the Details tab. Alternatively, use a tool like exiftool or examine the file's version info programmatically.
    Affected if The reported version number is less than 15.0.0.8 (for example, 15.0.0.7, 14.x, or earlier).
  3. Verify IrfanView loads the CADImage plugin
    Open IrfanView, go to Image menu and check if CAD/DXF file types are recognized, or attempt to open a DXF file to see if IrfanView uses the CADImage plugin to render it. You can also check Help > About Plugins to list loaded plugins.
    Affected if IrfanView successfully opens DXF files using the CADImage plugin, indicating the plugin is active.

A user is affected if the CADImage plugin is installed and loaded by IrfanView with a version number lower than 15.0.0.8, enabling the vulnerable DXF parser to be invoked when opening malicious files.

dbcve · scoped
Upgrade available Upgrade to 15.0.0.8 or later
Fixed in 15.0.0.8
Interim mitigation

Apply the vendor patch for the CADImage plugin when available. Until then, avoid opening untrusted DXF files and consider disabling or removing the CADImage plugin if DXF viewing is not required.

Recommended fix Moderate confidence

Cadimage version 15.0.0.8 or later

  1. 1. Identify the installed Cadimage plugin version by opening IrfanView and checking the 'Help' > 'About Plugins' menu, or by locating the cadimage.dll file in the IrfanView plugins directory and viewing its properties.
  2. 2. If the installed version is below 15.0.0.8, download the latest Cadimage plugin version (15.0.0.8 or later) from the official vendor website or IrfanView's plugin distribution page.
  3. 3. Close IrfanView completely before updating the plugin.
  4. 4. Navigate to the IrfanView plugins directory (typically C:\Program Files\IrfanView\Plugins or C:\Program Files (x86)\IrfanView\Plugins).
  5. 5. Backup the existing cadimage.dll file by copying it to a safe location.
  6. 6. Replace the existing cadimage.dll with the new version 15.0.0.8 or later.
  7. 7. Restart IrfanView and verify the plugin version through 'Help' > 'About Plugins' to confirm the update was successful.
  8. 8. Avoid opening untrusted DXF files, particularly from unknown or untrusted sources, as a secondary precaution until the upgrade is complete.
