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 CGM 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 CGM 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-26170.

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 suffers from an out-of-bounds read vulnerability when parsing CGM files due to insufficient validation of user-supplied data. This allows reading past the end of an allocated buffer, which can be leveraged for remote code execution in the context of the current process. Exploitation requires user interaction (opening a malicious CGM file).

MitigationAvoid opening untrusted or unverified CGM files. Update to patched versions of IrfanView and CADImage plugin when available, or disable the plugin if CGM file support 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. Confirm IrfanView installation
    Locate IrfanView installation directory, typically in Program Files (x86) or Program Files folder
    Affected if IrfanView is installed and using the CADImage plugin
  2. Identify CADImage plugin presence
    Look for CADImage plugin file (commonly cadimage.dll or similar) in the IrfanView plugins subfolder
    Affected if The CADImage plugin file exists in the IrfanView plugins directory
  3. Determine CADImage plugin version
    Right-click the CADImage plugin DLL, select Properties, then view the Version tab to find the product or file version
    Affected if The plugin version displayed is lower than 15.0.0.8
  4. Verify CGM file handling capability
    Check if CGM file type associations are registered with IrfanView, or test opening a CGM file in IrfanView to confirm the plugin handles it
    Affected if CGM files can be opened processed by the CADImage plugin in IrfanView

You are affected if IrfanView is installed with the CADImage plugin and the plugin version is below 15.0.0.8 and CGM file support is enabled or used.

Upgrade available Upgrade to 15.0.0.8 or later
Fixed in 15.0.0.8
Interim mitigation

Avoid opening untrusted or unverified CGM files. Update to patched versions of IrfanView and CADImage plugin when available, or disable the plugin if CGM file support is not required.

Recommended fix Moderate confidence

Cadimage 15.0.0.8 or later

  1. 1. Identify all systems with Cadimage plugin installed for IrfanView
  2. 2. Check current Cadimage version installed (likely visible in IrfanView via Plugins > CADImage or in Add/Remove Programs)
  3. 3. Download the latest Cadimage version from the official vendor website or trusted software distribution channel
  4. 4. Uninstall the current Cadimage plugin version
  5. 5. Install Cadimage version 15.0.0.8 or later
  6. 6. Verify the installed version matches the target version
  7. 7. Test that IrfanView can still open CGM and other supported CAD file formats
