Technical Description
Frontier is Substrate's Ethereum compatibility layer. Prior to commit aea528198b3b226e0d20cce878551fd4c0e3d5d0, at the end of a contract execution, when opcode SUICIDE marks a contract to be deleted, the software uses `storage::remove_prefix` (now renamed to `storage::clear_prefix`) to remove all storages associated with it. This is a single IO primitive call passing the WebAssembly boundary. For large contracts, the call (without providing a `limit` parameter) can be slow. In addition, for parachains, all storages to be deleted will be part of the PoV, which easily exceed relay chain PoV size limit. On the other hand, Frontier's maintainers only charge a fixed cost for opcode SUICIDE. The maintainers consider the severity of this issue high, because an attacker can craft a contract with a lot of storage values on a parachain, and then call opcode SUICIDE on the contract. If the transaction makes into a parachain block, the parachain will then stall because the PoV size will exceed rel
Remediation
Check the references section for vendor advisories and patches from parity. Update frontier to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
