CVE-2024-11573
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 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-24898.
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 confidenceThis is a memory corruption vulnerability in IrfanView's DXF file parser. The lack of proper validation of user-supplied data during DXF parsing leads to memory corruption, which can be exploited to achieve remote code execution in the context of the current process. An attacker must trick the 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.
-
Identify installed IrfanView versionOpen IrfanView and go to Help > About, or right-click the IrfanView executable and select Properties > Details to view the file versionAffected if The version is exactly 4.67
-
Confirm IrfanView is the affected versionCompare the displayed version number against the affected range (version 4.67)Affected if The installed version is 4.67 and no vendor patch has been applied
-
Determine if DXF file handling is activeCheck if IrfanView is configured to open .dxf files - look at Tools > File Types or Windows file type associations for DXF extensionAffected if DXF file association is enabled and IrfanView can be used to open DXF files
-
Identify recent DXF file activity (if compromised)Review Windows Event Viewer Security logs or antivirus logs for recent .dxf file opens by IrfanView, or check browser/download folders for recently downloaded DXF filesAffected if IrfanView was recently used to open a DXF file from an untrusted source
You are affected if IrfanView version 4.67 is installed and configured to handle DXF files, especially if users have opened or may open untrusted DXF files.
Generated from the published advisory. Verify against your own configuration.
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.
From vendor dataAvoid opening DXF files from untrusted or unknown sources. Keep IrfanView updated to receive any vendor patches. Consider using sandboxing or antivirus scanning on untrusted files before opening.
