codecs read out of bounds
- Library
- gh-115197: urllib.request no longer resolves the hostname
before checking it against the system’s proxy bypass list
on macOS and Windows.
- gh-115133: Fix tests for XMLPullParser with Expat 2.6.0.
- gh-81194: Fix a crash in socket.if_indextoname() with
specific value (UINT_MAX). Fix an integer overflow in
socket.if_indextoname() on 64-bit non-Windows platforms.
- gh-109858: Protect zipfile from “quoted-overlap”
zipbomb. It now raises BadZipFile when try to read an entry
that overlaps with other entry or central directory.
- gh-107077: Seems that in some conditions, OpenSSL will
return SSL_ERROR_SYSCALL instead of SSL_ERROR_SSL
when a certification verification has failed, but
the error parameters will still contain ERR_LIB_SSL
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:Factory/python38?expand=0&rev=149
- gh-108310: Fixed an issue where instances of ssl.SSLSocket were
vulnerable to a bypass of the TLS handshake and included
protections (like certificate verification) and treating sent
unencrypted data as if it were post-handshake TLS encrypted data.
Security issue reported as CVE-2023-40217 by Aapo Oksman. Patch by
Gregory P. Smith.
- gh-107845: tarfile.data_filter() now takes the location of
symlinks into account when determining their target, so it will no
longer reject some valid tarballs with
LinkOutsideDestinationError.
- gh-107565: Update multissltests and GitHub CI workflows to use
OpenSSL 1.1.1v, 3.0.10, and 3.1.2.
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:Factory/python38?expand=0&rev=137
- Add Revert-gh105127-left-tests.patch (gh#python/cpython!106941)
partially reverting CVE-2023-27043-email-parsing-errors.patch,
because of the regression in gh#python/cpython#106669.
- (bsc#1210638, CVE-2023-27043) Add
CVE-2023-27043-email-parsing-errors.patch, which detects email
address parsing errors and returns empty tuple to indicate the
parsing error (old API). (The patch is faulty,
gh#python/cpython#106669, but upstream decided not to just
revert it).
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:Factory/python38?expand=0&rev=135
- gh-103142: The version of OpenSSL used in Windows and
Mac installers has been upgraded to 1.1.1u to address
CVE-2023-2650, CVE-2023-0465, CVE-2023-0466, CVE-2023-0464,
as well as CVE-2023-0286, CVE-2022-4303, and CVE-2022-4303
fixed previously in 1.1.1t (gh-101727).
- gh-102153: urllib.parse.urlsplit() now strips leading C0
control and space characters following the specification for
URLs defined by WHATWG in response to CVE-2023-24329
(bsc#1208471).
- gh-99889: Fixed a security in flaw in uu.decode() that could
allow for directory traversal based on the input if no
out_file was specified.
- gh-104049: Do not expose the local on-disk
location in directory indexes produced by
http.client.SimpleHTTPRequestHandler.
- gh-103935: trace.__main__ now uses io.open_code() for files
to be executed instead of raw open().
- gh-102953: The extraction methods in tarfile, and
shutil.unpack_archive(), have a new filter argument that
allows limiting tar features than may be surprising or
dangerous, such as creating files outside the destination
directory. See Extraction filters for details (fixing
CVE-2007-4559, bsc#1203750).
- Remove upstreamed patches:
- CVE-2023-24329-blank-URL-bypass.patch
- CVE-2007-4559-filter-tarfile_extractall.patch
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:Factory/python38?expand=0&rev=130
gh#python/cpython#98086 (backport from Python 3.10 patch in
gh#python/cpython!99366), fixing bsc#1211158.
- Add CVE-2007-4559-filter-tarfile_extractall.patch to fix
CVE-2007-4559 (bsc#1203750) by adding the filter for
tarfile.extractall (PEP 706).
- Why in the world we download from HTTP?
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:Factory/python38?expand=0&rev=128
- python -m http.server no longer allows terminal
control characters sent within a garbage request to be
printed to the stderr server log.
This is done by changing the http.server
BaseHTTPRequestHandler .log_message method to replace control
characters with a \xHH hex escape before printing.
- Avoid publishing list of active per-interpreter
audit hooks via the gc module
- The IDNA codec decoder used on DNS hostnames by
socket or asyncio related name resolution functions no
longer involves a quadratic algorithm. This prevents a
potential CPU denial of service if an out-of-spec excessive
length hostname involving bidirectional characters were
decoded. Some protocols such as urllib http 3xx redirects
potentially allow for an attacker to supply such a
name (CVE-2022-45061).
- Update bundled libexpat to 2.5.0
- Port XKCP’s fix for the buffer overflows in SHA-3
(CVE-2022-37454).
- The deprecated mailcap module now refuses to inject
unsafe text (filenames, MIME types, parameters) into shell
commands. Instead of using such text, it will warn and act
as if a match was not found (or for test commands, as if the
test failed).
- Removed upstream patches:
- CVE-2022-37454-sha3-buffer-overflow.patch
- CVE-2022-45061-DoS-by-IDNA-decode.patch
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:Factory/python38?expand=0&rev=115
- Fix multiplying a list by an integer (list *= int): detect
the integer overflow when the new allocated length is close
to the maximum size.
- Fix a shell code injection vulnerability in the
get-remote-certificate.py example script. The script no
longer uses a shell to run openssl commands. (originally
filed as CVE-2022-37460, later withdrawn)
- Fix command line parsing: reject -X int_max_str_digits option
with no value (invalid) when the PYTHONINTMAXSTRDIGITS
environment variable is set to a valid limit.
- When ValueError is raised if an integer is larger than the
limit, mention the sys.set_int_max_str_digits() function in
the error message.
- Update bundled libexpat to 2.4.9
- Fixes a potential buffer overrun in msilib.
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:Factory/python38?expand=0&rev=106
- (CVE-2020-10735, bsc#1203125). Converting between int
and str in bases other than 2 (binary), 4, 8 (octal), 16
(hexadecimal), or 32 such as base 10 (decimal) now raises a
ValueError if the number of digits in string form is above a
limit to avoid potential denial of service attacks due to the
algorithmic complexity.
This new limit can be configured or disabled by environment
variable, command line flag, or sys APIs. See the integer
string conversion length limitation documentation. The
default limit is 4300 digits in string form.
- (CVE-2021-28861, bsc#1202624) http.server: Fix an open
redirection vulnerability in the HTTP server when an URI path
starts with //. Vulnerability discovered, and initial fix
proposed, by Hamza Avvan.
- Also other bugfixes:
- Fix contextvars HAMT implementation to handle iteration
over deep trees. The bug was discovered and fixed by Eli
Libman. See MagicStack/immutables#84 for more details.
- Fix ensurepip environment isolation for subprocess running
pip.
- Raise ProgrammingError instead of segfaulting on recursive
usage of cursors in sqlite3 converters. Patch by Sergey
Fedoseev.
- Add a new gh role to the documentation to link to GitHub
issues.
- Pin Jinja to a version compatible with Sphinx version
2.4.4.
- test_ssl is now checking for supported TLS version and
protocols in more tests.

* Complete list of changes is available at
https://docs.python.org/release/3.8.12/whatsnew/changelog.html
* Security
- 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.
