Name : python3.14 Product : Fedora 42 Version : 3.14.3 Release : 1.fc42 URL : https://www.python.org/ Summary : Version 3.14 of the Python interpreter Description : Python 3.14 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 python3.14 package provides the "python3.14" executable: the reference interpreter for the Python language, version 3. The majority of its standard library is provided in the python3.14-libs package, which should be installed automatically along with python3.14. The remaining parts of the Python standard library are broken out into the python3.14-tkinter and python3.14-test packages, which may need to be installed separately. Documentation for Python is provided in the python3.14-docs package. Packages containing additional libraries for Python are generally named with the "python3.14-" prefix. -------------------------------------------------------------------------------- Update Information: New version of the Python interpreter also bringing security fixes. -------------------------------------------------------------------------------- ChangeLog: * Wed Feb 4 2026 Karolina Surma <[email protected]> - 3.14.3-1 - Update to Python 3.14.3 - Fix CVE-2025-15366, CVE-2025-15367 * Sat Jan 17 2026 Fedora Release Engineering <[email protected]> - 3.14.2-3 - Rebuilt for https://fedoraproject.org/wiki/Fedora_44_Mass_Rebuild -------------------------------------------------------------------------------- References: [ 1 ] Bug #2431785 - CVE-2025-11468 python3.14: Missing character filtering in Python [fedora-42] https://bugzilla.redhat.com/show_bug.cgi?id=2431785 [ 2 ] Bug #2431794 - CVE-2026-0672 python3.14: Header injection in http.cookies.Morsel in Python [fedora-42] https://bugzilla.redhat.com/show_bug.cgi?id=2431794 [ 3 ] Bug #2431800 - CVE-2026-0865 python3.14: wsgiref.headers.Headers allows header newline injection in Python [fedora-42] https://bugzilla.redhat.com/show_bug.cgi?id=2431800 [ 4 ] Bug #2431816 - CVE-2025-15282 python3.14: Header injection via newlines in data URL mediatype in Python [fedora-42] https://bugzilla.redhat.com/show_bug.cgi?id=2431816 [ 5 ] Bug #2433819 - CVE-2026-1299 python3.14: email header injection due to unquoted newlines [fedora-42] https://bugzilla.redhat.com/show_bug.cgi?id=2433819 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program.
