| 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-2020-26241 | 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 | |||||

A JSON request can cause an access to the restricted functionality resulting in authorization bypass. An attacker can send JSON to trigger this vulnerability. | |||||

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-2017-12115 | 1 Ethereum | 1 Cpp-ethereum | 2019-10-03 | 6.8 MEDIUM | 8.1 HIGH |
| An exploitable improper authorization vulnerability exists in miner_setEtherbase API of cpp-ethereum's JSON-RPC (commit 4e1015743b95821849d001618a7ce82c7c073768). A JSON request can cause an access to the restricted functionality resulting in authorization bypass. | |||||
| CVE-2017-12117 | 1 Ethereum | 1 Cpp-ethereum | 2019-10-03 | 6.8 MEDIUM | 8.1 HIGH |
| An exploitable improper authorization vulnerability exists in miner_start 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-2017-12118 | 1 Ethereum | 1 Cpp-ethereum | 2019-10-03 | 6.8 MEDIUM | 8.1 HIGH |
| An exploitable improper authorization vulnerability exists in miner_stop API of cpp-ethereum's JSON-RPC (commit 4e1015743b95821849d001618a7ce82c7c073768). An attacker can send JSON to trigger this vulnerability. | |||||
| 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-2018-18920 | 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. | |||||
| CVE-2018-16733 | 1 Ethereum | 1 Go Ethereum | 2018-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||

| An exploitable unhandled exception vulnerability exists in multiple APIs of CPP-Ethereum JSON-RPC. Specially crafted JSON requests can cause an unhandled exception resulting in denial of service. An attacker can send malicious JSON to trigger this vulnerability. | |||||
