CVE-2024-11569
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 · uneditedIrfanView DXF 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 DXF 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-24873.
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 confidenceIrfanView contains an out-of-bounds read vulnerability in its DXF file parser. The flaw exists due to insufficient validation of user-supplied data during DXF file parsing, allowing an attacker to read past the end of an allocated buffer. Successful exploitation enables arbitrary code execution in the context of the current process by tricking a user into opening a malicious DXF file.

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 checksWork through these to decide whether this CVE applies to you.
-
Check if IrfanView is installedSearch for iview64.exe or i_view64.exe in Program Files directories (C:\Program Files\IrfanView or C:\Program Files (x86)\IrfanView), or query the Windows Registry under HKLM\SOFTWARE\IrfanViewAffected if IrfanView executable is found on the system
-
Determine installed version numberRight-click iview64.exe, select Properties, then view the Details tab to read the File Version, or run the command 'iview64.exe /?' and check the version outputAffected if The installed version is exactly 4.67
-
Verify DXF file handling by IrfanViewCheck Windows Registry under HKCR\.dxf\OpenWithProgids or HKCR\Applications\iview64.exe to see if IrfanView is associated with DXF file openingAffected if DXF files are configured to open with IrfanView
-
Identify recent DXF file processingReview Windows Event Viewer Application logs for Iview64.exe entries with .dxf file paths, or check Windows Prefetch files if available for evidence of recent DXF file opensAffected if IrfanView has been used to open DXF files on the system
The environment is affected if IrfanView version 4.67 is installed and the application is used or configured to open DXF files, since the out-of-bounds read vulnerability is triggered during DXF file parsing.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedAvoid opening untrusted or unverified DXF files in IrfanView until a vendor patch is available. Monitor for IrfanView security updates and apply them promptly.
