CVE-2018-16733ethereumgo_ethereum+18y ago08-09-2018 15:00

In Go Ethereum (aka geth) before 1.8.14, TraceChain in eth/api_tracer.go does not verify that the end block is after the start block.CVE-2018-19184ethereumgo_ethereum+17y ago12-11-2018 02:00

cmd/evm/runner.go in Go Ethereum (aka geth) 1.8.17 allows attackers to cause a denial of service (SEGV) via crafted bytecode.CVE-2018-20421ethereumgo_ethereum7y ago24-12-2018 03:00

Go Ethereum (aka geth) 1.8.19 allows attackers to cause a denial of service (memory consumption) by rewriting the length of a dynamic array in memory, and then writing data to a single memory location with a large index number, as demonstrated by use of "assembly { mstore }" followed by a "c[0xC800000] = 0xFF" assignment.CVE-2018-12018ethereumgo_ethereum+18y ago05-07-2018 02:00

The GetBlockHeadersMsg handler in the LES protocol implementation in Go Ethereum (aka geth) before 1.8.11 may lead to an access violation because of an integer signedness error for the array index, which allows attackers to launch a Denial of Service attack by sending a packet with a -1 query.Skip value. The vulnerable remote node would be crashed by such an attack immediately, aka the EPoD (Ethereum Packet of Death) issue.CVE-2021-41173ethereumgo_ethereum+24y ago26-10-2021 14:05

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.CVE-2021-42219ethereumgo_ethereum+14y ago16-03-2022 23:02

Go-Ethereum v1.10.9 was discovered to contain an issue which allows attackers to cause a denial of service (DoS) via sending an excessive amount of messages to a node. This is caused by missing memory in the component /ethash/algorithm.go.CVE-2021-39137ethereumgo_ethereum+25y ago24-08-2021 16:05

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.CVE-2021-43668ubuntugolang-goleveldb+24y ago18-11-2021 15:05

Go-Ethereum 1.10.9 nodes crash (denial of service) after receiving a serial of messages and cannot be recovered. They will crash with "runtime error: invalid memory address or nil pointer dereference" and arise a SEGV signal.CVE-2020-26265ethereumgo_ethereum+25y ago11-12-2020 16:45

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.CVE-2020-26241ethereumgo_ethereum+25y ago25-11-2020 01:25

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.CVE-2020-26264ethereumgo_ethereum+25y ago11-12-2020 16:45

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.CVE-2020-26240ethereumgo_ethereum+25y ago25-11-2020 01:25

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 CVE-2020-26242ethereumgo_ethereum+35y ago25-11-2020 01:25

Go Ethereum, or "Geth", is the official Golang implementation of the Ethereum protocol. In Geth before version 1.9.18, there is a Denial-of-service (crash) during block processing. This is fixed in 1.9.18.CVE-2022-37450ethereumgo_ethereum+14y ago05-08-2022 20:30

Go Ethereum (aka geth) through 1.10.21 allows attackers to increase rewards by mining blocks in certain situations, and using a manipulation of time-difference values to achieve replacement of main-chain blocks, aka Riskless Uncle Making (RUM), as exploited in the wild in 2020 through 2022.CVE-2022-29177ethereumgo_ethereum+24y ago20-05-2022 16:20

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.CVE-2022-23328ethereumgo_ethereum+14y ago04-03-2022 11:24

A design flaw in all versions of Go-Ethereum allows an attacker node to send 5120 pending transactions of a high gas price from one account that all fully spend the full balance of the account to a victim Geth node, which can purge all of pending transactions in a victim node's memory pool and then occupy the memory pool to prevent new transactions from entering the pool, resulting in a denial of service (DoS).CVE-2022-23327ethereumgo_ethereum+14y ago04-03-2022 11:24

A design flaw in Go-Ethereum 1.10.12 and older versions allows an attacker node to send 5120 future transactions with a high gas price in one message, which can purge all of pending transactions in a victim node's memory pool, causing a denial of service (DoS).CVE-2026-26313ethereumgo_ethereum+28mo ago19-02-2026 21:07

go-ethereum (geth) is a golang execution layer implementation of the Ethereum protocol. Prior to version 1.17.0, an attacker can cause high memory usage by sending a specially-crafted p2p message. The issue is resolved in the v1.17.0 release.CVE-2026-26314ethereumgo_ethereum+28mo ago19-02-2026 21:15

go-ethereum (geth) is a golang execution layer implementation of the Ethereum protocol. Prior to version 1.16.9, a vulnerable node can be forced to shutdown/crash using a specially crafted message. The problem is resolved in the v1.16.9 and v1.17.0 releases of Geth.CVE-2026-26315ethereumgo_ethereum+28mo ago19-02-2026 21:22

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.
