Summary
OpenZeppelin Contracts's SignatureChecker may revert on invalid EIP-1271 signers
Details

Impact

SignatureChecker.isValidSignatureNow is not expected to revert. However, an incorrect assumption about Solidity 0.8's abi.decode allows some cases to revert, given a target contract that doesn't implement EIP-1271 as expected.

The contracts that may be affected are those that use SignatureChecker to check the validity of a signature and handle invalid signatures in a way other than reverting. We believe this to be unlikely.

Patches

The issue was patched in 4.7.1.
