An update that solves nine vulnerabilities and has two security fixes can now be
installed.

## Description:

This update for python310 fixes the following issues:

Security issues fixed:

  * CVE-2026-0864: improper handling of line-ending characters can lead to
    configuration file injection when the `configparser` module is used
    (bsc#1269066).
  * CVE-2026-3276: quadratic complexity in `unicodedata.normalize()` can lead to
    DoS when processing specially crafted Unicode input (bsc#1267581).
  * CVE-2026-4360: in the `Tarfile.extract()` function, the filter parameter is
    not passed properly when extracting hardlinks (bsc#1269959).
  * CVE-2026-7210: `xml.parsers.expat` and `xml.etree.ElementTree` use
    insufficient entropy for Expat hash-flooding protection (bsc#1264962).
  * CVE-2026-7774: `tarfile.data_filter` path traversal bypass allows writing
    outside the extraction directory (bsc#1267821).
  * CVE-2026-8328: `ftpcp()` does not use actual peer address and trusts server-
    supplied PASV host address (bsc#1265268).
  * CVE-2026-11940: tarfile extraction filter bypass via a crafted archive
    allows escaping the destination directory and enables arbitrary file reads
    and writes (bsc#1268977).
  * CVE-2026-11972: infinite loop due to improper EOF handling in the tarfile
    module streaming mode can lead to DoS (bsc#1269788).
  * CVE-2026-15308: incremental `HTMLParser` allows CPU-exhaustion DoS via
    repeated unterminated markup declarations (bsc#1271192).

Non security issues fixed:

  * Improve testing for the support of `IPPROTO_UDPLITE`, which could be not
    present although header files are (bsc#1268375).
  * Use the system-wide crypto-policies (bsc#1211301).
  * Support changes required for Sphinx 9.
