CVE-2022-36025 Incorrect Conversion between Numeric Types in Besu Ethereum Client

Besu is a Java-based Ethereum client. In versions newer than 22.1.3 and prior to 22.7.1, Besu is subject to an Incorrect Conversion between Numeric Types. An error in 32 bit signed and unsigned types in the calculation of available gas in the CALL operations including DELEGATECALL results in...

Weight not properly refunded after EVM execution

Impact Previously, the worst case weight was always accounted as the block weight for all cases. In case of large EVM gas refunds, this can lead to block spamming attacks -- the adversary can construct blocks with transactions that have large amount of refunds or unused gases with reverts, and as...

Voting signature malleability of EVM's ecrecover in castVoteBySig

Lines of code Vulnerability details Proof of Concept EVM's ecrecover is susceptible to signature malleability which allows replay attacks, but that is mitigated here by doing receipt.hasVoted = true;. However, if any of the application logic changes, it might make signature malleability a risk fo...

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...
