GO-2022-0254 Consensus flaw during block processing in github.com/ethereum/go-ethereum

A vulnerability in the Geth EVM can cause a node to reject the canonical chain. A memory-corruption bug within the EVM can cause a consensus error, where vulnerable nodes obtain a different stateRoot when processing a maliciously crafted transaction. This, in turn, would lead to the chain being...

Denial of Service in Go-Ethereum

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 th...

Geth Node Vulnerable to DoS via maliciously crafted p2p message

Impact A vulnerable node is susceptible to crash when processing a maliciously crafted message from a peer, via the snap/1 protocol. The crash can be triggered by sending a malicious snap/1 GetTrieNodes package. Details On September 21, 2021, geth-team member Gary Rong @rjl493456442 found a way t...

Denial of service in geth

Impact Denial-of-service crash during block processing Details Affected versions suffer from a vulnerability which can be exploited through the MULMOD operation, by specifying a modulo of 0: mulmoda,b,0, causing a panic in the underlying library. The crash was in the uint256 library, where a buff...

GHSA-69V6-XC2J-R2JF Shallow copy bug in geth

Impact This is a Consensus vulnerability, 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,...
