Subject: [PATCH] gh-115133: Fix tests for XMLPullParser with Expat 2.6.0
Feeding the parser by too small chunks defers parsing to prevent
CVE-2023-52425. Future versions of Expat may be more reactive.
(cherry picked from commit 4a08e7b3431cd32a0daf22a33421cd3035343dc4)

Subject: [PATCH] 00435: gh-121650: Encode newlines in headers, and verify
headers are sound (GH-122233)
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.
(cherry picked from commit 097633981879b3c9de9a1dd120d3aa585ecc2384)
This patch also contains modified commit cherry picked from
c5bba853d5e7836f6d4340e18721d3fb3a6ee0f7.
This commit was backported to simplify the backport of the other commit
fixing CVE. The only modification is a removal of one test case which
tests multiple changes in Python 3.7 and it wasn't working properly
with Python 3.6 where we backported only one change.
