Summary

### 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.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
