Subject: [PATCH] gh-119451: Fix a potential denial of service in http.client
(GH-119454)
Reading the whole body of the HTTP response could cause OOM if
the Content-Length value is too large even if the server does not send
a large amount of data. Now the HTTP client reads large data by chunks,
therefore the amount of consumed memory is proportional to the amount
of sent data.
(cherry picked from commit 5a4c4a033a4a54481be6870aa1896fad732555b5)

Subject: [PATCH] [3.10] gh-119342: Fix a potential denial of service in
plistlib (GH-119343)
Reading a specially prepared small Plist file could cause OOM because file's
read(n) preallocates a bytes object for reading the specified amount of
data. Now plistlib reads large data by chunks, therefore the upper limit of
consumed memory is proportional to the size of the input file.

- Add CVE-2025-13836-http-resp-cont-len.patch (bsc#1254400,
CVE-2025-13836) to prevent reading an HTTP response from
a server, if no read amount is specified, with using
Content-Length per default as the length.
- Add CVE-2025-12084-minidom-quad-search.patch prevent quadratic
behavior in node ID cache clearing (CVE-2025-12084,
bsc#1254997).
- Add CVE-2025-13837-plistlib-mailicious-length.patch protect
against OOM when loading malicious content (CVE-2025-13837,
bsc#1254401).

Thu Dec 11 21:44:35 UTC 2025 - Matej Cepl <mcepl@cepl.eu>
* Update to 3.9.25:
- Security
- gh-137836: Add support of the “plaintext” element, RAWTEXT
elements “xmp”, “iframe”, “noembed” and “noframes”, and
optionally RAWTEXT element “noscript” in
html.parser.HTMLParser.
- gh-136063: email.message: ensure linear complexity for
legacy HTTP parameters parsing. Patch by Bénédikt Tran.
- gh-136065: Fix quadratic complexity in
os.path.expandvars() (CVE-2025-6075, bsc#1252974).
- Library
- gh-98793: Fix argument typechecks in
_overlapped.WSAConnect() and
_overlapped.Overlapped.WSASendTo() functions. bpo-44817:
Ignore WinError 53 (ERROR_BAD_NETPATH), 65
(ERROR_NETWORK_ACCESS_DENIED) and 161 (ERROR_BAD_PATHNAME)
when using ntpath.realpath().
- Core and Builtins
- gh-120384: Fix an array out of bounds crash in
list_ass_subscript, which could be invoked via some
specificly tailored input: including concurrent
modification of a list object, where one thread assigns
a slice and another clears it.
- gh-120298: Fix use-after free in list_richcompare_impl
which can be invoked via some specificly tailored evil
input.
- Remove upstreamed patches:
-CVE-2025-6075-expandvars-perf-degrad.patch
