* [3.8] gh-95778: CVE-2020-10735: Prevent DoS by very large int() (#96503)Gregory P. Smith2022-09-059-5/+304
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Correctly pre-check for int-to-str conversion Converting a large enough `int` to a decimal string raises `ValueError` as expected. However, the raise comes _after_ the quadratic-time base-conversion algorithm has run to completion. For effective DOS prevention, we need some kind of check before entering the quadratic-time loop. Oops! =) The quick fix: essentially we catch _most_ values that exceed the threshold up front. Those that slip through will still be on the small side (read: sufficiently fast), and will get caught by the existing check so that the limit remains exact. The justification for the current check. The C code check is: ```c max_str_digits / (3 * PyLong_SHIFT) <= (size_a - 11) / 10 ``` In GitHub markdown math-speak, writing $M$ for `max_str_digits`, $L$ for `PyLong_SHIFT` and $s$ for `size_a`, that check is: $$\left\lfloor\frac{M}{3L}\right\rfloor \le \left\lfloor\frac{s - 11}{10}\right\rfloor$$ From this it follows that $$\frac{M}{3L} < \frac{s-1}{10}$$ hence that $$\frac{L(s-1)}{M} > \frac{10}{3} > \log_2(10).$$ So $$2^{L(s-1)} > 10^M.$$ But our input integer $a$ satisfies $|a| \ge 2^{L(s-1)}$, so $|a|$ is larger than $10^M$. This shows that we don't accidentally capture anything _below_ the intended limit in the check. <!-- gh-issue-number: gh-95778 --> * Issue: gh-95778 <!-- /gh-issue-number --> Co-authored-by: Gregory P.

* bpo-45001: Make email date parsing more robust against malformed input ↵Miss Islington (bot)2021-08-261-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (GH-27946) (GH-27974) Various date parsing utilities in the email module, such as email.utils.parsedate(), are supposed to gracefully handle invalid input, typically by raising an appropriate exception or by returning None. The internal email._parseaddr._parsedate_tz() helper used by some of these date parsing routines tries to be robust against malformed input, but unfortunately it can still crash ungracefully when a non-empty but whitespace-only input is passed. This manifests as an unexpected IndexError. In practice, this can happen when parsing an email with only a newline inside a ‘Date:’ header, which unfortunately happens occasionally in the real world. Here's a minimal example: $ python Python 3.9.6 (default, Jun 30 2021, 10:22:16) [GCC 11.1.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import email.utils >>> email.utils.parsedate('foo') >>> email.utils.parsedate(' ') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python3.9/email/_parseaddr.py", line 176, in parsedate t = parsedate_tz(data) File "/usr/lib/python3.9/email/_parseaddr.py", line 50, in parsedate_tz res = _parsedate_tz(data) File "/usr/lib/python3.9/email/_parseaddr.py", line 72, in _parsedate_tz if data[0].endswith(',') or data[0].lower() in _daynames: IndexError: list index out of range The fix is rather straight-forward: guard against empty lists, after splitting on whitespace, but before accessing the first element.

| | | | | | | | | | | | | The address tuple for CAN_RAW no longer returns the address family after the introduction of CAN ISO-TP support in a30f6d45ac3. However, updating test_socket.CANTest.testSendFrame was missed as part of the change, so the test incorrectly attempts to index past the last tuple item to retrieve the address family. This removes the now-redundant check for equality against socket.AF_CAN, as the tuple will not contain the address family.

* [3.8] bpo-41100: Support macOS 11 Big Sur and Apple Silicon Macs (#25806)Ned Deily2021-05-023-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * bpo-41100: Support macOS 11 and Apple Silicon on Python 3.8 This is a partial backport of bpo-41100 changes `e8b1c038b14b5fc8120aab62c9bf5fb840274cb6` and `96d906b144e6e6aa96c5ffebecbcc5d38034bbda` for Python 3.8. We introduce the ability to build Python from source for `arm64` on macOS, but we do not make a promise of support. This allows us to omit support for Universal2 binaries as well as weak-linking of symbols from the macOS SDK based on the deployment target, which are larger changes much more difficult to merge. This also includes a backport of subsequent bpo-42688 change `7e729978fa08a360cbf936dc215ba7dd25a06a08` to fix build errors with external `libffi`. * bpo-41116: Ensure system supplied libraries are found on macOS 11 (GH-23301) (GH-23455) On macOS system provided libraries are in a shared library cache and not at their usual location.

| | | | | | | | | | | | | | | | | (GH-24906) 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. Use MAX_UNICODE constant in unicodeobject.c.
