.. section: Security
CVE-2021-3426: Remove the ``getfile`` feature of the :mod:`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.

.. date: 2021-03-13-03-48-14
.. nonce: g-Hah3
.. section: Security
:mod:`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 :class:`ftplib.FTP`
instances to ``True`` to re-enable it.

Galindo.

.. section: Core and Builtins
Python no longer fails at startup with a fatal error if a command line
argument contains an invalid Unicode character. The
:c:func:`Py_DecodeLocale` function now escapes byte sequences which would be
decoded as Unicode characters outside the [U+0000; U+10ffff] range.

.. section: Library
Fixed long-standing bug of smtplib.SMTP where doing AUTH LOGIN with
initial_response_ok=False will fail.
The cause is that SMTP.auth_login _always_ returns a password if provided
with a challenge string, thus non-compliant with the standard for AUTH
LOGIN.
Also fixes bug with the test for smtpd.
