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 DXF File Parsing Memory Corruption Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of IrfanView. 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 memory corruption condition. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-24752.

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

A memory corruption vulnerability exists in IrfanView's DXF file parsing functionality due to insufficient validation of user-supplied data. When processing specially crafted DXF files, the lack of proper bounds checking allows an attacker to overwrite memory regions, potentially enabling arbitrary code execution within the context of the running process.

MitigationApply the vendor-supplied patch or update IrfanView to the latest version. Until patched, exercise extreme caution when opening DXF files from untrusted sources.

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 is installed
    Search for IrfanView in Program Files directories or check the Windows registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for IrfanView entries
    Affected if IrfanView is found on the system
  2. Determine installed IrfanView version
    Right-click the IrfanView executable (irfanview.exe), select Properties, and check the Details tab for the File Version, or run 'irfanview.exe /?' to display version information
    Affected if The installed version is exactly 4.67
  3. Confirm DXF file handling capability
    Check if the DXF plugin (dxf.dll) exists in the IrfanView plugins directory, typically found at C:\Program Files\IrfanView\Plugins\ or C:\Program Files (x86)\IrfanView\Plugins\
    Affected if The DXF plugin is present and loaded by IrfanView
  4. Identify recent DXF file processing
    Review the system's recent files list within IrfanView, or check the application logs for opened .dxf files. On Windows, examine the Jump List or recent documents for IrfanView activity involving .dxf extensions
    Affected if DXF files have been opened or processed in IrfanView 4.67

The environment is affected if IrfanView version 4.67 is installed and the DXF plugin is available or has been used to process DXF files.

Mitigation

Apply the vendor-supplied patch or update IrfanView to the latest version. Until patched, exercise extreme caution when opening DXF files from untrusted sources.

Recommended fix Moderate confidence

IrfanView version 4.70 or latest stable release

  1. 1. Navigate to the official IrfanView website at https://www.irfanview.com/
  2. 2. Download the latest version of IrfanView (version 4.70 or later)
  3. 3. Uninstall the current version (4.67) from your system
  4. 4. Install the newly downloaded version
  5. 5. Ensure all IrfanView plugins are also updated to their latest versions to maintain compatibility
  6. 6. Verify the installation was successful by opening IrfanView
  7. 7. Test opening a legitimate DXF file to confirm the parsing functionality works correctly
Caveat Minor: Some legacy plugin compatibility may require updating plugins; ensure plugins match the new IrfanView version
