| | | | | | | | | | | | | | | | | | | | | | | | | (GH-122233) (#122611) Per RFC 2047: > [...] these encoding schemes allow the > encoding of arbitrary octet values, mail readers that implement this > decoding should also ensure that display of the decoded data on the > recipient's terminal will not cause unwanted side-effects It seems that the "quoted-word" scheme is a valid way to include a newline character in a header value, just like we already allow undecodable bytes or control characters. They do need to be properly quoted when serialized to text, though. This should fail for custom fold() implementations that aren't careful about newlines.

* [3.8] gh-113171: gh-65056: Fix "private" (non-global) IP address ranges ↵Petr Viktorin2024-05-071-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (GH-113179) (GH-113186) (GH-118177) (GH-118479) The _private_networks variables, used by various is_private implementations, were missing some ranges and at the same time had overly strict ranges (where there are more specific ranges considered globally reachable by the IANA registries). This patch updates the ranges with what was missing or otherwise incorrect. 100.64.0.0/10 is left alone, for now, as it's been made special in [1]. The _address_exclude_many() call returns 8 networks for IPv4, 121 networks for IPv6. [1] https://github.com/python/cpython/issues/61602 In 3.10 and below, is_private checks whether the network and broadcast address are both private. In later versions (where the test wss backported from), it checks whether they both are in the same private network. For 0.0.0.0/0, both 0.0.0.0 and 255.225.255.255 are private, but one is in 0.0.0.0/8 ("This network") and the other in 255.255.255.255/32 ("Limited broadcast"). --------- Co-authored-by: Jakub Stasiak <jakub@stasiak.at>

| | | | | | | | (GH-115210) (GH-116069) 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.

| | | | | | | | | | | | | | | | | | flaw (#108321) 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.
