GHSA-pvh2-pj76-4m96 Specification non-compliance in JUMPI

• crates.io evm: < 0.31.0 → fixed in 0.31.0

Impact In `evm` crate `< 0.31.0`, `JUMPI` opcode's condition is checked after the destination validity check. However, according to Geth and OpenEthereum, the condition check should happen before the destination validity check. Patches This is a high severity security advisory if you use `evm` crate for Ethereum mainnet. In this case, you should update your library dependency immediately to on or after `0.31.0`. This is a low severity security advisory if you use `evm` crate in Frontier or in a standalone blockchain, because there's no security exploit possible with this advisory. It is not recommended to update to on or after `0.31.0` until all the normal chain upgrade preparations have been done. If you use Frontier or other `pallet-evm` based Substrate blockchain, please ensure to update your `spec_version` before updating this. For other blockchains, please make sure to follow a hard-fork process before you update this. Workarounds If you are dependent on an older version of `evm` and cannot update due to API interface changes, please contact Wei by email ([email protected]), who will be happy to help you to publish patch releases for older `evm` versions.
