CVE-2024-31172
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 · uneditedOut-of-bounds Read vulnerability in Open Networking Foundation (ONF) libfluid (libfluid_msg module). This vulnerability is associated with program routine fluid_msg::of10::StatsReplyTable::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 confidenceAn out-of-bounds read vulnerability exists in libfluid's fluid_msg::of10::StatsReplyTable::unpack function, which handles OpenFlow 1.0 statistics reply message parsing. The vulnerability allows reading memory beyond allocated buffer boundaries, potentially leading to information disclosure or denial of service.

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 libfluid_msg library is in useSearch your codebase or dependencies for references to 'libfluid', 'fluid_msg', or the package 'libfluid-msg'Affected if the library is present in your project dependencies or imports
-
Identify the installed libfluid_msg versionCheck your package manager, dependency lock file (e.g., package.json, requirements.txt, Cargo.lock), or the version string in the libfluid source codeAffected if the version is 0.1.0 exactly
-
Verify OpenFlow 1.0 message processing is enabledInspect your configuration files or code for OpenFlow 1.0 (OF10) controller or switch setup, specifically looking for of10::Controller or of10::Switch instancesAffected if OpenFlow 1.0 protocol support is enabled in your deployment
-
Check if StatsReplyTable messages are processedReview logs, traffic captures, or code that handles OFPMP_TABLE, OFPMP_PORT_STATS, OFPMP_QUEUE_STATS, or other OpenFlow 1.0 statistics request/reply typesAffected if your environment processes OpenFlow 1.0 statistics reply messages (StatsReply)
-
Inspect the StatsReplyTable::unpack function implementationLocate the libfluid source file containing the unpack function in fluid_msg/of10/stats.cc or similar path, and verify if bounds checking exists before buffer readsAffected if the code lacks proper buffer length validation before accessing memory in the unpack function
Your environment is affected if libfluid_msg version 0.1.0 is in use and OpenFlow 1.0 statistics reply messages are being 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 dataUpgrade to a patched version of libfluid if available; otherwise, implement proper bounds checking in the StatsReplyTable::unpack function to validate buffer lengths before reading. Consider input validation and length checks on all incoming OpenFlow messages.
