Summary:

An update for python3 is now available for EulerOS Virtualization release 2.10.1

EulerOS Security has rated this update as having a security impact of Important.A Common Vunlnerability Scoring System(CVSS)base score, which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.General:

Python is an accessible, high-level, dynamically typed, interpreted programming language, designed with an emphasis on code readability. It includes an extensive standard library, and has a vast ecosystem of third-party libraries. The python3 package provides the "python3" executable: the reference interpreter for the Python language, version 3. The majority of its standard library is provided in the python3-libs package, which should be installed automatically along with python3. The remaining parts of the Python standard library are broken out into the python3-tkinter and python3-test packages, which may need to be installed separately. Documentation for Python is provided in the python3-docs package. Packages containing additional libraries for Python are generally named with the "python3-" prefix.

Security Fix(es):

There is a defect in the CPython "tarfile" module affecting the "TarFile" extraction and entry enumeration APIs. The tar implementation would process tar archives with negative offsets without error, resulting in an infinite loop and deadlock during the parsing of maliciously crafted tar archives. This vulnerability can be mitigated by including the following patch after importing the "tarfile" module: https://gist.github.com/sethmlarson/1716ac5b82b73dbcbf23ad2eff8b33e1(CVE-2025-8194)

During an address list folding when a separating comma ends up on a folded line and that line is to be unicode-encoded then the separator itself is also unicode-encoded. Expected behavior is that the separating comma remains a plan comma. This can result in the address header being misinterpreted by...
