CWE: CWE-400 \u2014 Uncontrolled Resource Consumption
The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources.

Code:
    def test_hashes_large_file(self):
        class FakeLargeFile:
            """
            A class that pretends to be a huge file (~1.3GB)
            """

            def read(self, bytes):
                self.iterations -= 1
                if not self.iterations:
                    return b""

                return b"A" * bytes
