Security update for python311
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).
