An update that solves 10 vulnerabilities and has two security fixes can now be
installed.

## Description:

This update for python fixes the following issues:

  * CVE-2026-0864: improper handling of line-ending characters can lead to
    configuration file injection when the `configparser` module is used
    (bsc#1269066).
  * CVE-2026-1703: files may be extracted outside the installation directory
    when installing and extracting maliciously crafted wheel archives
    (bsc#1257599).
  * CVE-2026-3219: python-pip: pip doesn't reject concatenated ZIP
    (bsc#1262467).
  * CVE-2026-3276: quadratic complexity in `unicodedata.normalize()` can lead to
    DoS when processing specially crafted Unicode input (bsc#1267581).
  * CVE-2026-6357: pip self-update functionality can import newly installed
    modules after wheel installation (bsc#1263442 bsc#1263443).
  * CVE-2026-7210: `xml.parsers.expat` and `xml.etree.ElementTree` use
    insufficient entropy for Expat hash-flooding protection (bsc#1264962).
  * CVE-2026-8328: `ftpcp()` does not use actual peer address and trusts server-
    supplied PASV host address (bsc#1265268).
  * CVE-2026-8643: Path traversal via malicious entry point name in pip wheel
    installation allows arbitrary file overwrite (bsc#1266669).
  * 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).
  * Regression in `http.cookies` (bsc#1263083).
