Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The ethereum crate before 0.18.0 checks for transaction signature malleability only on legacy transactions, not on EIP-2930, EIP-1559 or EIP-7702 transactions, which deviates from the EIP-2 specification. The source says this is high severity for Ethereum mainnet use and low or informational for single-implementation blockchains, since malleability is not itself a security issue. Upgrade to ethereum 0.18.0, which fixes the issue; the source gives no workaround beyond manual checks.
