FuelVM is vulnerable to heap memory allocation re-use bug

Impact A memory safety vulnerability was present in the Fuel Virtual Machine FuelVM, where memory reads could bypass expected access controls. Specifically, when a smart contract performed a mload or other opcodes which access memory on memory that had been deallocated using ret, it was still abl...
