Fedora Linux 9437 Published by

Fedora 44 administrators can now apply a batch of security patches, covering seven major system packages. The updates address critical vulnerabilities across fuse-overlayfs, Python 3.12, PHP 8.5.9, Nextcloud 34.0.2, Exim 4.99.5, PostgreSQL 16.14, and RabbitMQ Server 4.2.9 by patching privilege escalation risks, arbitrary code execution flaws, SQL injection vectors, and cross-site scripting issues. System operators can install the corrected versions through the dnf package manager using their respective advisory identifiers. These patches prevent potential system compromise and keep containerized environments, web servers, and database services running securely on Fedora 44.

Update Information:

Update to fuse-overlayfs 1.17 to fix CVE-2026-52791: privilege escalation via
SUID/SGID bit preservation on file truncation. When a file with SUID/SGID bits
is truncated, those privilege bits should be cleared but were not in versions
prior to 1.17, allowing potential privilege escalation in rootless containers.

Name : python3.12
Product : Fedora 44
Version : 3.12.13
Release : 6.fc44
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.

PHP is an HTML-embedded scripting language. PHP attempts to make it
easy for developers to write dynamically generated web pages. PHP also
