"Python changelog :

bpo-37463: ssl.match_hostname() no longer accepts IPv4 addresses with
additional text after the address and only quad-dotted notation
without trailing whitespaces. Some inet_aton() implementations ignore
whitespace and all data after whitespace, e.g.'127.0.0.1 whatever'.

bpo-35907: CVE-2019-9948: Avoid file reading by disallowing
local-file:// and local_file:// URL schemes in URLopener().open() and
URLopener().retrieve() of urllib.request.

bpo-36742: Fixes mishandling of pre-normalization characters in
urlsplit().

bpo-30458: Address CVE-2019-9740 by disallowing URL paths with
embedded whitespace or control characters through into the underlying
http client request. Such potentially malicious header injection URLs
now cause an http.client.InvalidURL exception to be raised.

bpo-33529: Prevent fold function used in email header encoding from
entering infinite loop when there are too many non-ASCII characters in
a header.

bpo-35755: shutil.which() now uses os.confstr('CS_PATH') if available
and if the PATH environment variable is not set. Remove also the
current directory from posixpath.defpath. On Unix, shutil.which() and
the subprocess module no longer search the executable in the current
directory if the PATH environment variable is not set.");
