- 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
