Description

Impact

An issue in s2n-quic results in the endpoint shutting down after receiving an empty UDP packet on a connection.

No AWS services are affected by this issue and customers of AWS services do not need to take action. Applications using s2n-quic should upgrade their application to the most recent release of s2n-quic.

Impacted version: s2n-quic v1.22.0.

Patches

The patch is included in s2n-quic v1.23.0.

If you have any questions or comments about this advisory we ask that you contact AWS/Amazon Security via our vulnerability reporting page or directly via email to [email protected]. Please do not create a public GitHub issue.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for s2n-quic. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update s2n-quic to 1.23.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hxq4-mx37-fqvg is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-hxq4-mx37-fqvg is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-hxq4-mx37-fqvg. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
