GHSA-4G63-C64M-25W9 OpenZeppelin Contracts's SignatureChecker may revert on invalid EIP-1271 signers

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...

CVE-2022-31172

OpenZeppelin Contracts (library) is affected by CVE-2022-31172 in versions 4.1.0–4.7.1, where SignatureChecker.isValidSignatureNow may revert due to an incorrect assumption about Solidity 0.8 ABI decoding, especially when a target contract does not implement EIP-1271 as expected. The vulnerabilit...
