Security update for python310
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
configparsermodule 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.expatandxml.etree.ElementTreeuse insufficient entropy for Expat hash-flooding protection (bsc#1264962). - CVE-2026-7774:
tarfile.data_filterpath 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:
- [kernel 7.1] udplite was removed -> python fails in tests (bsc#1268375).
- crypto-policies: Extend the crypto-policies support for mozilla-nss, openjdk, krb5, bind, stunnel, openssh, libssh and more packages (bsc#1211301).

Описание
When using the "configparser" module to write configuration files containing multi-line text values with carriage return characters (\r) the resulting file could be injected with unexpected keys and values if the attacker controls the written value.

Описание
tarfile.extractall() with the 'data' or 'tar' filter could be bypassed by a crafted archive where a hardlink references a symlink stored at a deeper name than the hardlink itself. The extraction fallback validated the symlink at it's archived location but recreated it at the hardlink's shallower path, letting a relative target the filter judged contained escape the destination directory. This allowed a malicious tar archive to create a symlink pointing outside the destination, enabling out-of-destination file reads or writes. This was an incomplete fix of CVE-2025-4330.

Описание
When using the "tarfile" module with a file opened in "streaming mode" (mode="r|") the tarfile module did not properly handle EOF, making archive parsing take exponentially longer.

The incremental HTML parser (html.parser.HTMLParser) allows for CPU denial-of-service through repeated unterminated markup declarations when processing uncontrolled data.

Описание
unicodedata.normalize() can take excessive CPU time when processing specially crafted Unicode input containing long runs of combining characters with alternating Canonical Combining Class values. This affects all normalization forms.

Описание
In the Tarfile.extract() function, the filter parameter is not passed properly when extracting hardlinks. An affected system that extracts content from untrusted tar files could end up writing files with an unexpected uid/gid despite the user passing filter='data' to the extract() function.

Описание
`xml.parsers.expat` and `xml.etree.ElementTree` use insufficient entropy for Expat hash-flooding protection, which allows a crafted XML document to trigger hash flooding.\r\n\r\nFully mitigating this vulnerability requires both updating libexpat to 2.8.0 or later and applying this patch.

Описание
tarfile.data_filter could be bypassed using crafted link entries, including symlinks with empty or directory-like names, to redirect later archive members outside the intended extraction directory. This allowed a malicious tar archive to cause tarfile.extractall() to write files outside the destination directory, subject to the permissions of the extracting process.

Описание
The ftpcp() function in Lib/ftplib.py was not updated when CVE-2021-4189 was fixed. While makepasv() was patched to replace server-supplied PASV host addresses with the actual peer address (getpeername()[0]), ftpcp() still calls parse227() directly and passes the raw attacker-controllable IP address and port to target.sendport(). This patch is related to CVE-2021-4189.
