fc2c98f [3.9] gh-115197: Stop resolving host in urllib.request proxy bypass (GH-115210) (GH-116068) Use of a proxy is intended to defer DNS for the hosts to the proxy itself, rather than a potential for information leak of the host doing DNS resolution itself for any reason. Proxy bypass lists are strictly name based. Most implementations of proxy support agree.

2007624 [3.9] gh-115398: Expose Expat >=2.6.0 reparse deferral API (CVE-2023-52425) (GH-115623) (GH-116272) Allow controlling Expat >=2.6.0 reparse deferral (CVE-2023-52425) by adding five new methods: - `xml.etree.ElementTree.XMLParser.flush` - `xml.etree.ElementTree.XMLPullParser.flush` - `xml.parsers.expat.xmlparser.GetReparseDeferralEnabled` - `xml.parsers.expat.xmlparser.SetReparseDeferralEnabled` - `xml.sax.expatreader.ExpatParser.flush` Based on the "flush" idea from https://github.com/python/cpython/pull/115138#issuecomment-1932444270 .

d2cd0a3 [3.9] gh-108342: Make ssl TestPreHandshakeClose more reliable (GH-108370) (#108407) * In preauth tests of test_ssl, explicitly break reference cycles invoving SingleConnectionTestServerThread to make sure that the thread is deleted. Otherwise, the test marks the environment as altered because the threading module sees a "dangling thread" (SingleConnectionTestServerThread). This test leak was introduced by the test added for the fix of issue gh-108310. * Use support.SHORT_TIMEOUT instead of hardcoded 1.0 or 2.0 seconds timeout. * SingleConnectionTestServerThread.run() catchs TimeoutError * Fix a race condition (missing synchronization) in test_preauth_data_to_tls_client(): the server now waits until the client connect() completed in call_after_accept(). * test_https_client_non_tls_response_ignored() calls server.join() explicitly. * Replace "localhost" with server.listener.getsockname()[0].

264b1da [3.9] gh-108310: Fix CVE-2023-40217: Check for & avoid the ssl pre-close flaw (#108320) gh-108310: Fix CVE-2023-40217: Check for & avoid the ssl pre-close flaw 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. The vulnerability is caused when a socket is connected, data is sent by the malicious peer and stored in a buffer, and then the malicious peer closes the socket within a small timing window before the other peers’ TLS handshake can begin. After this sequence of events the closed socket will not immediately attempt a TLS handshake due to not being connected but will also allow the buffered data to be read as if a successful TLS handshake had occurred.

cec1e9d [3.9] gh-95778: CVE-2020-10735: Prevent DoS by very large int() (#96502) * Correctly pre-check for int-to-str conversion (#96537) 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.
