- Update to 3.9.16:

- python -m http.server no longer allows terminal control
    characters sent within a garbage request to be printed to the
    stderr server log.
    This is done by changing the http.server
    BaseHTTPRequestHandler .log_message method to replace control
    characters with a \xHH hex escape before printing.
  - Avoid publishing list of active per-interpreter audit hooks
    via the gc module
  - The IDNA codec decoder used on DNS hostnames by socket or
    asyncio related name resolution functions no longer involves
    a quadratic algorithm. This prevents a potential CPU denial
    of service if an out-of-spec excessive length hostname
    involving bidirectional characters were decoded. Some
    protocols such as urllib http 3xx redirects potentially allow
    for an attacker to supply such a name (CVE-2015-20107).
  - Update bundled libexpat to 2.5.0
  - Port XKCP’s fix for the buffer overflows in SHA-3
    (CVE-2022-37454).
  - On Linux the multiprocessing module returns to using
    filesystem backed unix domain sockets for communication with
    the forkserver process instead of the Linux abstract socket
    namespace. Only code that chooses to use the “forkserver”
    start method is affected.
    Abstract sockets have no permissions and could allow any
    user on the system in the same network namespace (often
    the whole system) to inject code into the multiprocessing
    forkserver process. This was a potential privilege
    escalation. Filesystem based socket permissions restrict this
    to the forkserver process user as was the default in Python

Abstract sockets have no permissions and could allow any

forkserver process. This was a potential privilege
escalation. Filesystem based socket permissions restrict this
to the forkserver process user as was the default in Python
3.8 and earlier.
This prevents Linux CVE-2022-42919.
- The deprecated mailcap module now refuses to inject unsafe
text (filenames, MIME types, parameters) into shell
commands. Instead of using such text, it will warn and act
as if a match was not found (or for test commands, as if the
test failed).
- Removed upstreamed patches:
- CVE-2015-20107-mailcap-unsafe-filenames.patch
- CVE-2022-42919-loc-priv-mulitproc-forksrv.patch
