CVE-2024-11546
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 Write 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 write 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-24714.
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 · moderate confidenceIrfanView contains an out-of-bounds write vulnerability in its DXF file parser due to insufficient validation of user-supplied data. An attacker can exploit this by tricking a user into opening a malicious DXF file, allowing 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.
-
Confirm IrfanView is installedLocate IrfanView on the system - typically installed in Program Files (e.g., C:\Program Files\IrfanView or C:\Program Files (x86)\IrfanView). Check for i_view64.exe or IrfanView.exe.Affected if IrfanView executable is present on the system
-
Determine installed versionRight-click the IrfanView executable, select Properties, and view the Details tab for the Version information. Alternatively, open IrfanView and go to Help > About IrfanView.Affected if The version number displayed is 4.67 exactly
-
Check if DXF file support is enabledLook for DXF-related plugins in the IrfanView plugins folder (typically C:\Program Files\IrfanView\Plugins). Check for files like DXF.dll or similar DXF handling plugins. Also verify file association settings for .dxf files.Affected if DXF plugin files exist and .dxf file associations are configured in IrfanView
-
Inspect recent DXF file handling activityCheck the IrfanView recent files list or Windows shell history for any recently opened .dxf files. Examine the application's file open dialog for .dxf filter presence.Affected if DXF files can be opened by IrfanView and the user has opened or may open such files
The user is affected if IrfanView version 4.67 is installed with DXF file support or plugins enabled, allowing malicious DXF files to be processed.

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 until IrfanView releases an official patch. Consider blocking or restricting DXF file associations as a temporary workaround.
