|---|---|---|---|
| 2018-12-24 | CVE-2018-20421 | Allocation of Resources Without Limits or Throttling vulnerability in Ethereum GO Ethereum 1.8.19 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. | 7.5 |
| 2018-11-12 | CVE-2018-19184 | NULL Pointer Dereference vulnerability in Ethereum GO Ethereum 1.8.17 cmd/evm/runner.go in Go Ethereum (aka geth) 1.8.17 allows attackers to cause a denial of service (SEGV) via crafted bytecode. | 7.5 |
| 2018-11-12 | CVE-2018-18920 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Ethereum Py-Evm 0.2.0 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. | 8.8 |
| 2018-09-08 | CVE-2018-16733 | Improper Input Validation vulnerability in Ethereum GO Ethereum 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. | 7.5 |
| 2018-07-05 | CVE-2018-12018 | Improper Validation of Array Index vulnerability in Ethereum GO Ethereum 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. | 7.5 |
| 2018-01-19 | CVE-2017-14457 | Out-of-bounds Read vulnerability in Ethereum Virtual Machine An exploitable information leak/denial of service vulnerability exists in the libevm (Ethereum Virtual Machine) `create2` opcode handler of CPP-Ethereum. | 8.2 |
| 2018-01-19 | CVE-2017-12119 | Improper Check for Unusual or Exceptional Conditions vulnerability in Ethereum Cpp-Ethereum An exploitable unhandled exception vulnerability exists in multiple APIs of CPP-Ethereum JSON-RPC. | 7.5 |
| 2018-01-19 | CVE-2017-12118 | Incorrect Authorization vulnerability in Ethereum Cpp-Ethereum An exploitable improper authorization vulnerability exists in miner_stop API of cpp-ethereum's JSON-RPC (commit 4e1015743b95821849d001618a7ce82c7c073768). | 8.1 |
| 2018-01-19 | CVE-2017-12116 | Incorrect Authorization vulnerability in Ethereum Aleth An exploitable improper authorization vulnerability exists in miner_setGasPrice API of cpp-ethereum's JSON-RPC (commit 4e1015743b95821849d001618a7ce82c7c073768). | 8.1 |
| 2018-01-19 | CVE-2017-12113 | Incorrect Authorization vulnerability in Ethereum Cpp-Ethereum An exploitable improper authorization vulnerability exists in admin_nodeInfo API of cpp-ethereum's JSON-RPC (commit 4e1015743b95821849d001618a7ce82c7c073768). | 8.1 |
