Description

Impact

A vulnerable node, can be made to consume unbounded amounts of memory when handling specially crafted p2p messages sent from an attacker node.

Details

The p2p handler spawned a new goroutine to respond to ping requests. By flooding a node with ping requests, an unbounded number of goroutines can be created, leading to resource exhaustion and potentially crash due to OOM.

Patches

The fix is included in geth version 1.12.1-stable, i.e, 1.12.2-unstable and onwards.

Fixed by https://github.com/ethereum/go-ethereum/pull/27887

Workarounds

No known workarounds.

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. 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 github.com/ethereum/go-ethereum to 1.12.1-stable or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-ppjg-v974-84cm 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-ppjg-v974-84cm 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-ppjg-v974-84cm. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
