Security update for python
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
configparsermodule 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.expatandxml.etree.ElementTreeuse 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).

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.

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.

Описание
When pip is installing and extracting a maliciously crafted wheel archive, files may be extracted outside the installation directory. The path traversal is limited to prefixes of the installation directory, thus isn't able to inject or overwrite executable files in typical situations.

Описание
pip handles concatenated tar and ZIP files as ZIP files regardless of filename or whether a file is both a tar and ZIP file. This behavior could result in confusing installation behavior, such as installing "incorrect" files according to the filename of the archive. New behavior only proceeds with installation if the file identifies uniquely as a ZIP or tar archive, not as both.

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
pip prior to version 26.1 would run self-update check functionality after installing wheel files which required importing well-known Python modules names. These module imports were intentionally deferred to increase startup time of the pip CLI. The patch changes self-update functionality to run before wheels are installed to prevent newly-installed modules from being imported shortly after the installation of a wheel package. Users should still review package contents prior to installation.

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
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.

Описание
pip would treat console_scripts and gui_scripts as paths instead of file names without sanitizing the resolved absolute path to the installation directory, leading to entry points being installed outside the installation directory.
