vyper vulnerable to storage allocator overflow

Impact

The storage allocator does not guard against allocation overflows. This can result in vulnerabilities like the following:

owner: public(address)
take_up_some_space: public(uint256[10])
buffer: public(uint256[max_value(uint256)])

@external
def initialize():
    self.owner = msg.sender

@external
def foo(idx: uint256, data: uint256):
    self.buffer[idx] = data

Per @toonvanhove, "An attacker can overwrite the owner variable by calling this contract with calldata: 0x04bc52f8 fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff5 ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff (spaces inserted for readability)
0x04bc52f8 is the selector for foo(uint256, uint256), and the last argument fff...fff is the new value for the owner variable."
