OpenZeppelin Contracts's ERC165Checker may revert instead of returning false
Summary
OpenZeppelin Contracts's ERC165Checker may revert instead of returning false
Original description
The description as published by the source.
OpenZeppelin Contracts is a library for smart contract development. Versions 4.0.0 until 4.7.1 are vulnerable to ERC165Checker reverting instead of returning false. ERC165Checker.supportsInterface is designed to always successfully return a boolean, and under no circumstance 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-165 as expected, specifically if it returns a value other than 0 or 1. The contracts that may be affected are those that use ERC165Checker to check for support for an interface and then handle the lack of support in a way other than reverting. The issue was patched in version 4.7.1.
