CVE-2025-67432
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 · uneditedA stack overflow in the ZBarcode_Encode function of Monkeybread Software MBS DynaPDF Plugin v21.3.1.1 allows attackers to cause a Denial of Service (DoS) via a crafted input.

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.
-
Locate the MBS DynaPDF Plugin installationSearch for files named 'MBS DynaPDF' or 'DynaPDF' with .plugin, .dll, .so, or .dylib extensions in application directories, plugin folders, or the system library path. Common locations include application plugin directories and system plugin/system plugin folders.Affected if The MBS DynaPDF Plugin file is found on the system
-
Identify the plugin versionRight-click the plugin file and select Properties (Windows) or Get Info (macOS), or use command-line tools: 'dir' on Windows or 'ls -la' on Unix-like systems to check file metadata. Also check any version information in the filename or accompanying version.txt/readme files.Affected if The version is 21.3.1.1 or earlier (before any patched version is released)
-
Verify the ZBarcode_Encode function is in useSearch application source code, logs, or memory dumps for calls to 'ZBarcode_Encode' function, or inspect the plugin's exported function symbols using tools like 'dumpbin /exports' (Windows), 'nm' (Linux), or 'otool -Iv' (macOS).Affected if The ZBarcode_Encode function is exported and accessible to the application
-
Check for barcode processing with untrusted inputReview application code or configuration that passes barcode data to the DynaPDF plugin. Look for barcode generation workflows where user-supplied or external data is used as input to encoding functions.Affected if The application processes barcode data through ZBarcode_Encode without strict input validation
The system is affected if the MBS DynaPDF Plugin version 21.3.1.1 is installed and the application uses the ZBarcode_Encode function with potentially untrusted barcode input.

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 dataUpdate to a patched version when available, or implement input validation/constraints on barcode data before passing to the ZBarcode_Encode function.
