CVE-2024-11565
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 CGM 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 CGM 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-24866.
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 CGM (Computer Graphics Metafile) file parser due to insufficient validation of user-supplied data. The lack of bounds checking allows reading past the end of an allocated buffer, which can be leveraged to achieve remote code execution in the context of the current process. User interaction is required (opening a malicious CGM 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.
-
Confirm IrfanView installationLocate the IrfanView executable (irfanview.exe) in the program directory, typically found under C:\Program Files\IrfanView or C:\Program Files (x86)\IrfanViewAffected if IrfanView is installed on the system
-
Identify installed IrfanView versionRight-click irfanview.exe, select Properties, and check the File Version field under the Details tab, or run irfanview.exe /? to display version information in the command promptAffected if Version number equals 4.67 exactly
-
Check for CGM file handling capabilityExamine the IrfanView plugins folder (usually C:\Program Files\IrfanView\Plugins or C:\Program Files (x86)\IrfanView\Plugins) for the presence of a CGM-related plugin file such as CGM.dll or similar CGM handling moduleAffected if CGM processing capability exists in the plugins directory and would be loaded when opening CGM files
The environment is affected if IrfanView version 4.67 is installed with CGM file handling capability present, and a user opens a malicious CGM file.

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 · scopedApply vendor-supplied patch from IrfanView when available. Until then, avoid opening untrusted CGM files and consider disabling CGM file handling or using alternative image viewers for untrusted content.
IrfanView 4.70 or latest stable release
- Check the official IrfanView website (irfanview.com) for the latest version
- Navigate to the downloads or news section to find security updates
- Download and install the latest IrfanView version (currently version 4.70 or higher)
- Verify the installation by checking Help > About IrfanView
- Ensure the CGM plugin is also updated if applicable
