Go Ethereum

go-ethereum (Geth) is a golang execution layer implementation of the Ethereum protocol. Prior to version 1.16.9, through a flaw in the ECIES cryptography implementation, an attacker may be able to extract bits of the p2p node key. The issue is resolved in the v1.16.9 and v1.17.0 releases of Geth. Geth maintainers recommend rotating the node key after applying the upgrade, which can be done by removing the file `<datadir>/geth/nodekey` before starting Geth.

go-ethereum (geth) is a golang execution layer implementation of the Ethereum protocol. Prior to 1.13.15, a vulnerable node can be made to consume very large amounts of memory when handling specially crafted p2p messages sent from an attacker node. The fix has been included in geth version `1.13.15` and onwards.

go-ethereum (geth) is a golang execution layer implementation of the Ethereum protocol. A vulnerable node, can be made to consume unbounded amounts of memory when handling specially crafted p2p messages sent from an attacker node. The fix is included in geth version `1.12.1-stable`, i.e, `1.12.2-unstable` and onwards. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Go Ethereum is the official Golang implementation of the Ethereum protocol. Prior to version 1.10.17, a vulnerable node, if configured to use high verbosity logging, can be made to crash when handling specially crafted p2p messages sent from an attacker node. Version 1.10.17 contains a patch that addresses the problem. As a workaround, setting loglevel to default level (`INFO`) makes the node not vulnerable to this attack.

Go Ethereum is the official Golang implementation of the Ethereum protocol. Prior to version 1.10.9, a vulnerable node is susceptible to crash when processing a maliciously crafted message from a peer. Version v1.10.9 contains patches to the vulnerability. There are no known workarounds aside from upgrading.

go-ethereum is the official Go implementation of the Ethereum protocol. In affected versions a consensus-vulnerability in go-ethereum (Geth) could cause a chain split, where vulnerable versions refuse to accept the canonical chain. Further details about the vulnerability will be disclosed at a later date. A patch is included in the upcoming `v1.10.8` release. No workaround are available.

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.

Go Ethereum, or "Geth", is the official Golang implementation of the Ethereum protocol. In Geth before version 1.9.25 a denial-of-service vulnerability can make a LES server crash via malicious GetProofsV2 request from a connected LES client. This vulnerability only concerns users explicitly enabling les server; disabling les prevents the exploit. The vulnerability was patched in version 1.9.25.

Go Ethereum, or "Geth", is the official Golang implementation of the Ethereum protocol. This is a Consensus vulnerability in Geth before version 1.9.17 which can be used to cause a chain-split where vulnerable nodes reject the canonical chain. Geth's pre-compiled dataCopy (at 0x00...04) contract did a shallow copy on invocation. An attacker could deploy a contract that writes X to an EVM memory region R, then calls 0x00..04 with R as an argument, then overwrites R to Y, and finally invokes the RETURNDATACOPY opcode. When this contract is invoked, a consensus-compliant node would push X on the EVM stack, whereas Geth would push Y. This is fixed in version 1.9.17.

Go Ethereum, or "Geth", is the official Golang implementation of the Ethereum protocol. An ethash mining DAG generation flaw in Geth before version 1.9.24 could cause miners to erroneously calculate PoW in an upcoming epoch (estimated early January, 2021). This happened on the ETC chain on 2020-11-06. This issue is relevant only for miners, non-mining nodes are unaffected. This issue is fixed as of 1.9.24
