| CVE-2022-29177 | 1 Ethereum | 1 Go Ethereum | 2022-06-06 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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-2021-43668 | 1 Ethereum | 1 Go Ethereum | 2021-11-23 | 2.1 LOW | 5.5 MEDIUM |
| 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-2021-41173 | 1 Ethereum | 1 Go Ethereum | 2021-10-28 | 3.5 LOW | 5.7 MEDIUM |
| 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-2021-39137 | 1 Ethereum | 1 Go Ethereum | 2021-08-31 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2017-12116 | 1 Ethereum | 1 Aleth | 2021-01-19 | 6.8 MEDIUM | 8.1 HIGH |
| An exploitable improper authorization vulnerability exists in miner_setGasPrice API of cpp-ethereum's JSON-RPC (commit 4e1015743b95821849d001618a7ce82c7c073768). A JSON request can cause an access to the restricted functionality resulting in authorization bypass. An attacker can send JSON to trigger this vulnerability. | |||||
| CVE-2020-26800 | 1 Ethereum | 1 Aleth | 2021-01-13 | 4.3 MEDIUM | 5.5 MEDIUM |
| A stack overflow vulnerability in Aleth Ethereum C++ client version <= 1.8.0 using a specially crafted a config.json file may result in a denial of service. | |||||
| CVE-2020-26265 | 1 Ethereum | 1 Go Ethereum | 2020-12-14 | 3.5 LOW | 5.3 MEDIUM |
| 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-2020-26264 | 1 Ethereum | 1 Go Ethereum | 2020-12-14 | 4.0 MEDIUM | 6.5 MEDIUM |
| 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-2017-14451 | 1 Ethereum | 1 Ethereum | 2020-12-09 | 7.5 HIGH | 10.0 CRITICAL |
| An exploitable out-of-bounds read vulnerability exists in libevm (Ethereum Virtual Machine) of CPP-Ethereum. A specially crafted smart contract code can cause an out-of-bounds read which can subsequently trigger an out-of-bounds write resulting in remote code execution. An attacker can create/send malicious smart contract to trigger this vulnerability. | |||||
| CVE-2020-26241 | 1 Ethereum | 1 Go Ethereum | 2020-12-03 | 5.5 MEDIUM | 7.1 HIGH |
| 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-2020-26242 | 1 Ethereum | 1 Go Ethereum | 2020-12-03 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2020-26240 | 1 Ethereum | 1 Go Ethereum | 2020-12-03 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2018-20421 | 1 Ethereum | 1 Go Ethereum | 2019-10-03 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2018-15890 | 1 Ethereum | 1 Ethereumj | 2019-06-20 | 10.0 HIGH | 9.8 CRITICAL |
| An issue was discovered in EthereumJ 1.8.2. There is Unsafe Deserialization in ois.readObject in mine/Ethash.java and decoder.readObject in crypto/ECKey.java. When a node syncs and mines a new block, arbitrary OS commands can be run on the server. | |||||
| CVE-2018-18920 | 1 Ethereum | 1 Py-evm | 2019-02-04 | 6.8 MEDIUM | 8.8 HIGH |
| Py-EVM v0.2.0-alpha.33 allows attackers to make a vm.execute_bytecode call that triggers computation._stack.values with '"stack": [100, 100, 0]' where b'\x' was expected, resulting in an execution failure because of an invalid opcode. This is reportedly related to "smart contracts can be executed indefinitely without gas being paid." | |||||
| CVE-2018-19184 | 1 Ethereum | 1 Go Ethereum | 2018-12-13 | 5.0 MEDIUM | 7.5 HIGH |
| cmd/evm/runner.go in Go Ethereum (aka geth) 1.8.17 allows attackers to cause a denial of service (SEGV) via crafted bytecode. | |||||

| 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-2018-12018 | 1 Ethereum | 1 Go Ethereum | 2018-09-04 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
