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 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. 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-24604.

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 an out-of-bounds read vulnerability in its DWG file parser due to insufficient validation of user-supplied data. This allows reading past the end of an allocated buffer, which can be leveraged by an attacker to execute arbitrary code in the context of the current process when a user opens a malicious DWG file.

MitigationAvoid opening untrusted DWG files and apply vendor patches when available; consider disabling DWG preview or adding file-type restrictions in enterprise environments until the official fix is released.

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
    Check for IrfanView in program directories or use system search to locate irfanview.exe
    Affected if IrfanView is not installed on the system
  2. Identify installed version
    Right-click irfanview.exe, select Properties, and view the Version tab to determine the exact version number
    Affected if The installed version is 4.67
  3. Verify DWG plugin availability
    Locate the plugins directory (typically named 'Plugins' in the IrfanView installation folder) and check for DWG-related files such as DWG.dll or iwdsgdsg.dll
    Affected if DWG support plugins are present in the Plugins folder
  4. Check for recent DWG file access
    Review recent file history or prefetch data for .dwg file openings through IrfanView
    Affected if Users have opened DWG files using IrfanView recently

The environment is affected if IrfanView version 4.67 is installed with DWG file handling capabilities enabled and users have opened or may open DWG files.
