CVE-2024-31181
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::of13::GroupStats::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 confidenceOut-of-bounds read vulnerability in libfluid_msg module's fluid_msg::of13::GroupStats::unpack function. The routine fails to properly validate buffer boundaries before reading data when unpacking OpenFlow 1.3 GroupStats messages, potentially allowing memory disclosure beyond allocated buffers.

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 for libfluid_msg in project dependencies (package.json, Cargo.toml, requirements.txt) or list installed packages. Look for the fluid_msg library in Python or C++ projects using libfluid.Affected if The libfluid_msg library is present in the environment
-
Identify installed version of libfluid_msgRun package manager command to get version: pip show libfluid-msg (Python) or check Cargo.toml/version header (C++). Compare against the affected version 0.1.0.Affected if The installed version is exactly 0.1.0
-
Check if OpenFlow 1.3 support is enabledInspect code or configuration for OpenFlow 1.3 (of13) message handling. Look for imports like 'from fluid_msg import of13' or of13::GroupStats usage in C++ code.Affected if OpenFlow 1.3 protocol support is active and GroupStats messages are processed
-
Verify GroupStats unpack function is reachableReview application logs or code to confirm incoming OpenFlow messages include GroupStats requests. The vulnerability triggers during unpack of received GroupStats data.Affected if The application processes incoming OpenFlow GroupStats messages from switches
The environment is affected only if libfluid_msg version 0.1.0 is installed AND OpenFlow 1.3 GroupStats messages are being received and unpacked by the application.

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 dataRestrict network exposure of libfluid-based controllers/agents, implement input validation on all incoming OpenFlow messages, and monitor for patches from ONF.
