-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2026-4e99b7fe5f 2026-03-02 00:40:42.980517+00:00 -------------------------------------------------------------------------------- Name : python3.12 Product : Fedora 43 Version : 3.12.12 Release : 4.fc43 URL : https://www.python.org/ Summary : Version 3.12 of the Python interpreter Description : Python 3.12 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 python3.12 package provides the "python3.12" executable: the reference interpreter for the Python language, version 3. The majority of its standard library is provided in the python3.12-libs package, which should be installed automatically along with python3.12. The remaining parts of the Python standard library are broken out into the python3.12-tkinter and python3.12-test packages, which may need to be installed separately. Documentation for Python is provided in the python3.12-docs package. Packages containing additional libraries for Python are generally named with the "python3.12-" prefix. -------------------------------------------------------------------------------- Update Information: Security fixes for CVE-2026-1299, CVE-2026-0865, CVE-2025-15366 and CVE-2025-15367 -------------------------------------------------------------------------------- ChangeLog: * Fri Feb 6 2026 Tomáš Hrnčiar <thrnciar@redhat.com> - 3.12.12-4 - Security fixes for CVE-2026-0865, CVE-2025-15366 and CVE-2025-15367 -------------------------------------------------------------------------------- References: [ 1 ] Bug #2431627 - CVE-2025-15366 python3.12: IMAP command injection in user-controlled commands [fedora-43] https://bugzilla.redhat.com/show_bug.cgi?id=2431627 [ 2 ] Bug #2431651 - CVE-2025-15367 python3.12: POP3 command injection in user-controlled commands [fedora-43] https://bugzilla.redhat.com/show_bug.cgi?id=2431651 [ 3 ] Bug #2431830 - CVE-2026-0865 python3.12: wsgiref.headers.Headers allows header newline injection in Python [fedora-43] https://bugzilla.redhat.com/show_bug.cgi?id=2431830 [ 4 ] Bug #2433827 - CVE-2026-1299 python3.12: email header injection due to unquoted newlines [fedora-43] https://bugzilla.redhat.com/show_bug.cgi?id=2433827 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program.
