Vyper from 0.1.0b4 before 0.3.0 contains a memory corruption vulnerability caused by an incorrect stack tip pointer when internal function calls appear inside tuples or nested calls. Contracts using such calls as tuple elements, call arguments, or builtin arguments like concat or ecrecover can return corrupted values or pass wrong arguments to external calls.
