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 Type Confusion 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 type confusion condition. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22184.

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

IrfanView contains a type confusion vulnerability in its DXF file parser due to insufficient validation of user-supplied data. When parsing a maliciously crafted DXF file, the lack of proper validation can lead to a type confusion condition that allows an attacker to execute arbitrary code in the context of the current process.

MitigationAvoid opening DXF files from untrusted or unknown sources. Apply vendor patches for IrfanView when available.

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. Check if IrfanView is installed
    Look for IrfanView in Program Files or Program Files (x86), or search for irfanview.exe on the system. You can also check Add/Remove Programs or the Windows registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
    Affected if IrfanView is found on the system
  2. Determine the installed version
    Right-click irfanview.exe, select Properties, and check the Details tab for the File Version. Alternatively, open IrfanView and go to Help > About IrfanView
    Affected if The version is exactly 4.62
  3. Verify DXF file handling capability
    Check if DXF file associations are registered for IrfanView (look for .dxf in Default Apps or search the registry under HKCR\.dxf), or check IrfanView's plugins directory for dxffilt.dll
    Affected if DXF file support is enabled or associated with IrfanView
  4. Inspect recent or monitored DXF files
    Check the user's recent files list, Windows Jump List, or any file monitoring logs for .dxf files that may have been opened with IrfanView
    Affected if DXF files have been opened with IrfanView version 4.62

You are affected if IrfanView version 4.62 is installed AND DXF file handling is enabled or DXF files have been processed with this version.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Avoid opening DXF files from untrusted or unknown sources. Apply vendor patches for IrfanView when available.

Recommended fix Moderate confidence

Check IrfanView official releases for version 4.63 or later (if available)

  1. Check IrfanView's official website (www.irfanview.com) for the latest version and security updates
  2. Verify if version 4.63 or later has been released as the security patch
  3. If a newer version exists, download and install it from the official IrfanView website
  4. Alternatively, check the IrfanView forums or news section for any security-related announcements regarding CVE-2024-11508
  5. Apply the update to remediate the type confusion vulnerability in DXF file parsing
  6. As a temporary mitigation, avoid opening untrusted or unknown DXF files in IrfanView until the patch is applied
Caveat No known breaking changes typically associated with IrfanView security updates
