Package

go-ethereum (golang)

Affected versions

<v1.9.24

Patched versions

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.
