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 · unedited
Improper Null Termination vulnerability in Open Networking Foundation (ONF) libfluid (libfluid_msg module). This vulnerability is associated with program routine fluid_msg::of10::Port:unpack. This issue affects libfluid: 0.1.0.

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 confidence

Improper Null Termination vulnerability in the fluid_msg::of10::Port::unpack routine of libfluid_msg module (version 0.1.0). When parsing OpenFlow 1.0 Port messages, the unpack function fails to properly null-terminate strings, potentially leading to buffer overread and information disclosure.

MitigationUpdate libfluid to a patched version if available; otherwise, implement proper null-termination in the Port::unpack routine and validate all string buffers before processing. Consider network segmentation to limit exposure to untrusted OpenFlow messages.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Locate libfluid_msg library in your environment
    Search for files named libfluid_msg.so, libfluid_msg.a, or headers like fluid_msg.hpp in your project directories and system libraries. Check your dependency manifests (e.g., package.json, CMakeLists.txt, requirements.txt) for a libfluid_msg entry.
    Affected if The libfluid_msg library is present in your environment and version 0.1.0 is installed or linked.
  2. Verify the exact version of libfluid_msg
    Check your dependency lock file, package manager records, or compile-time version macros. If the library is compiled, inspect the version string in the binary or its build metadata.
    Affected if The installed version is exactly 0.1.0.
  3. Confirm OpenFlow 1.0 message processing is enabled
    Review your application code or configuration for usage of the of10 namespace and Port class. Look for calls to Port::unpack or similar parsing functions that handle OpenFlow 1.0 port structures.
    Affected if Your code uses fluid_msg::of10::Port to parse OpenFlow 1.0 Port messages.
  4. Identify if untrusted network traffic reaches the vulnerable code
    Audit your network configuration and OpenFlow controller/agent setup to determine whether the system receives OpenFlow messages from untrusted or external sources.
    Affected if Untrusted or external OpenFlow messages can reach the component using libfluid_msg.

You are affected only if libfluid_msg version 0.1.0 is installed, your code invokes the of10::Port::unpack routine, and untrusted OpenFlow 1.0 Port messages can be processed by your application.
