CVE-2024-11563
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-24860.
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 parsing functionality. The lack of proper validation of user-supplied data during DXF file processing allows reading past the end of an allocated buffer, which can be leveraged by an attacker to achieve arbitrary code execution in the context of the current process.

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.
-
Verify IrfanView is installedSearch for IrfanView in the system: check Program Files (C:\Program Files\IrfanView) or Program Files (x86), or use the search function. Look for irfanview.exe.Affected if IrfanView is found on the system
-
Determine the installed versionRight-click irfanview.exe, select Properties, go to the Details tab, and check the Product Version field. Alternatively, open IrfanView and go to Help > About IrfanView.Affected if The version is exactly 4.67
-
Confirm DXF file support existsCheck for DXF-related plugins or file type support. Look in the IrfanView plugins folder (usually C:\Program Files\IrfanView\Plugins) for DXF-related files, or open a .dxf file to see if it loads.Affected if DXF files can be opened or processed by IrfanView
-
Review recent DXF file activityCheck the system's recently opened files for any .dxf files opened via IrfanView. This can be done via File Explorer Recent items or by reviewing jump lists.Affected if There are recent DXF files opened in IrfanView
A system is affected only if IrfanView version 4.67 is installed and the user opens a specially crafted DXF file with the application.

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 untrusted DXF files in IrfanView. Monitor for IrfanView patches and apply them promptly. Consider deploying endpoint detection and response (EDR) solutions to detect suspicious process behavior.
