* SUSE Linux Micro 6.1
An update that solves 13 vulnerabilities and has three fixes 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-2026-1502: HTTP client proxy tunnel headers not validated for CR/LF
(bsc#1261969).
* 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-2026-4786: Incomplete mitigation of %action expansion for command
injection to webbrowser.open() (bsc#1262319).
* CVE-2026-6019: BaseCookie.js_output() does not neutralize embedded
characters (bsc#1262654).
* CVE-2026-6100: Arbitrary code execution or information disclosure via use-
after-free in decompression modules (bsc#1262098).
* 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:
* Regression in `http.cookies` (bsc#1263083).
* udplite was removed -> python fails in tests (bsc#1268375).
* Conflicts between different versions of Python (bsc#1258364).
