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):

If the value passed to os.path.expandvars() is user-controlled a performance degradation is possible when expanding environment variables.(CVE-2025-6075)

When using http.cookies.Morsel, user-controlled cookie values and parameters can allow injecting HTTP headers into messages. Patch rejects all control characters within cookie names, values, and parameters.(CVE-2026-0672)

The email module, specifically the "BytesGenerator" class, didn't properly quote newlines for email headers when serializing an email message allowing for header injection when an email is serialized. This is only applicable if using "LiteralHeader" writing headers that don't respect email folding rules, the new behavior will reject the incorrectly folded headers in "BytesGenerator".(CVE-2026-1299)Legal...
