The pip package before 19.2 for Python allows Directory Traversal when a
URL is given in an install command, because a Content-Disposition header
can have …/ in a filename, as demonstrated by overwriting the
/root/.ssh/authorized_keys file. This occurs in _download_http_url in
_internal/download.py.
