CVE-2024-31173
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::StatsReplyFlow::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's of10 module specifically in the fluid_msg::of10::StatsReplyFlow::unpack routine. The vulnerability allows reading memory outside allocated buffers when unpacking OpenFlow 1.0 flow stats reply messages, potentially exposing sensitive memory contents or causing 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.
-
Identify libfluid_msg dependencySearch your project's dependency manifest (package.json, requirements.txt, Cargo.toml, go.mod, pom.xml, or similar) for 'libfluid', 'libfluid_msg', or 'fluid' libraries. Also grep source code for '#include <fluid' or 'libfluid' imports.Affected if libfluid_msg version 0.1.0 is listed as a dependency or present in the environment
-
Verify installed versionRun your package manager's version query command (npm list, pip show, cargo tree, mvn dependency:tree, or equivalent) to confirm the exact installed version of libfluid_msg.Affected if The installed version resolves to exactly 0.1.0
-
Confirm OpenFlow 1.0 usageSearch configuration files and runtime logs for OpenFlow 1.0 protocol references. Look for 'of10', 'openflow 1.0', or 'OF10' in switch controller configurations, controller logs, or API settings.Affected if Your environment is configured to use or negotiate OpenFlow 1.0 protocol with switches
-
Check flow stats processingMonitor or trace application behavior during OpenFlow flow stats reply handling. Search code for calls to StatsReplyFlow, flow_stats_reply, or unpack methods in of10 context. Review network traffic captures for OFPT_STATS_REPLY (type 17) messages.Affected if The application processes OpenFlow 1.0 flow statistics reply messages from switches
You are affected if libfluid_msg version 0.1.0 is in use AND your environment processes OpenFlow 1.0 flow stats replies, which triggers the vulnerable StatsReplyFlow::unpack routine.

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 libfluid to a patched version if available, or apply bounds-checking fixes to the StatsReplyFlow::unpack routine to validate buffer lengths before reading. If no patch exists, implement input validation and buffer boundary checks in the affected unpack function.
