Description

Python reports:

bpo-42278: Replaced usage of tempfile.mktemp() with TemporaryDirectory to avoid

a potential race condition.

bpo-44394: Update the vendored copy of libexpat to 2.4.1 (from 2.2.8) to get the

fix for the CVE-2013-0340 "Billion Laughs" vulnerability. This copy is most used

on Windows and macOS.

bpo-43124: Made the internal putcmd function in smtplib sanitize input for

presence of \r and \n characters to avoid (unlikely) command injection.

bpo-36384: ipaddress module no longer accepts any leading zeros in IPv4 address

strings. Leading zeros are ambiguous and interpreted as octal notation by some

libraries. For example the legacy function socket.inet_aton() treats leading

zeros as octal notation. glibc implementation of modern inet_pton() does not

accept any leading zeros. For a while the ipaddress module used to accept ambiguous

leading zeros.
