Fixes the following security issues:
- bpo-42988: CVE-2021-3426: Remove the getfile feature of the pydoc module
which could be abused to read arbitrary files on the disk (directory
traversal vulnerability). Moreover, even source code of Python modules
can contain sensitive data like passwords. Vulnerability reported by
David Schwörer.
- bpo-43285: ftplib no longer trusts the IP address value returned from the
server in response to the PASV command by default. This prevents a
malicious FTP server from using the response to probe IPv4 address and
port combinations on the client network.
Code that requires the former vulnerable behavior may set a
trust_server_pasv_ipv4_address attribute on their ftplib.FTP instances to
True to re-enable it.
- bpo-43439: Add audit hooks for gc.get_objects(), gc.get_referrers() and
gc.get_referents(). Patch by Pablo Galindo.
Note: 3.9.3 was recalled due to introducing unintentional ABI
incompatibility, and fixes re-released as 3.9.4:
