- bpo#42988 (bsc#1183374) 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.
- bpo-43660: Fix crash that happens when replacing sys.stderr
with a callable that can remove the object while an exception
is being printed. Patch by Pablo Galindo.
- bpo-35883: Python no longer fails at startup with a fatal
error if a command line argument contains an invalid Unicode
character. The Py_DecodeLocale() function now escapes byte
sequences which would be decoded as Unicode characters
outside the [U+0000; U+10ffff] range.
- bpo-43406: Fix a possible race condition where
PyErr_CheckSignals tries to execute a non-Python signal
handler.
- bpo-35930: Raising an exception raised in a “future” instance

Python 3 in SUSE
==============
* Subpackages *
Python 3 is split into several subpackages, based on external dependencies.
The main package 'python3' has soft dependencies on all subpackages needed to
assemble the standard library; however, these might not all be installed by default.
If you attempt to import a module that is currently not installed, an ImportError is thrown,
with instructions to install the missing subpackage. Installing the subpackage might result
in installing libraries that the subpackage requires to function.
* ensurepip *
The 'ensurepip' module from Python 3 standard library (PEP 453) is supposed to deploy
a bundled copy of the pip installer. This makes no sense in a managed distribution like SUSE.
Instead, you need to install package 'python3-pip'. Usually this will be installed automatically
with 'python3'.
Using 'ensurepip' when pip is not installed will result in an ImportError with instructions
to install 'python3-pip'.
* Documentation *
You can find documentation in seprarate packages: python3-doc and
python3-doc-pdf. These contan following documents:
Tutorial, What's New in Python, Global Module Index, Library Reference,
Macintosh Module Reference, Installing Python Modules, Distributing Python
Modules, Language Reference, Extending and Embedding, Python/C API,
Documenting Python
The python3-doc package constains many text files from source tarball.
* Interactive mode *
Interactive mode is by default enhanced with of history and command completion.
If you don't like these features, you can unset the PYTHONSTARTUP variable
in your .profile or disable it system wide in /etc/profile.d/python.sh.
