An update that solves nine vulnerabilities and has one security fix can now be
installed.
## Description:
This update for python311 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 issue fixed:
* Improve testing for the support of `IPPROTO_UDPLITE`, which could be not
present although header files are (bsc#1268375).
