While playing with fuzzing and Python, I stumbled upon an infinite loop in Python's tarfile module: just open the attached file with `tarfile.open('timeout-a52710a313fdb35fb428c3399277cb640fe2f686')`, and Python will be endlessly stuck in the `_proc_pax` function in tarfile.py, likely due to a missing check of `length` being strictly superior to zero.
