Description

Impact

Versions of Geth built with Go <1.15.5 or <1.14.12 are most likely affected by a critical DoS-related security vulnerability. The golang team has registered the underlying flaw as ‘CVE-2020-28362’.

We recommend all users to rebuild (ideally v1.9.24) with Go 1.15.5 or 1.14.12, to avoid node crashes. Alternatively, if you are running binaries distributed via one of our official channels, we’re going to release v1.9.24 ourselves built with Go 1.15.5.

Patches

This is not an issue in go-ethereum, rebuilding an older version with Go 1.15.5 or 1.14.12 will suffice to address the vulnerability.

Workarounds

Rebuilding with Go 1.15.5 or 1.14.12 will suffice to address the vulnerability.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/ethereum/go-ethereum, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update github.com/ethereum/go-ethereum to 1.9.24 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-m6gx-rhvj-fh52 is resolved across your whole dependency graph.

  3. Workarounds

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
