Lifecycle Timeline
1DescriptionNVD
Go Ethereum, or "Geth", is the official Golang implementation of the Ethereum protocol. In Geth from version 1.9.4 and before version 1.9.20 a consensus-vulnerability could cause a chain split, where vulnerable versions refuse to accept the canonical chain. The fix was included in the Paragade release version 1.9.20. No individual workaround patches have been made -- all users are recommended to upgrade to a newer version.
AnalysisAI
Go Ethereum, or "Geth", is the official Golang implementation of the Ethereum protocol. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable. No vendor patch available.
