Fedora Linux 9371 Published by

Fedora administrators should immediately apply several critical security patches released for both Fedora 43 and Fedora 44 systems. The hplip package receives version 3.26.4 to address arbitrary code execution flaws, while python-wsgidav upgrades to 4.3.4 to resolve a known vulnerability in its WebDAV implementation. X.Org server components gain eight separate security fixes for Fedora 44, and the roundcubemail webmail client gets updated to version 1.7.1 with patches for SQL injection, cross-site scripting, and file deletion risks. System owners can deploy these essential upgrades quickly by running standard dnf commands that pull the advisory packages directly from official repositories.

Fedora 43 Update: python-wsgidav-4.3.4-1.fc43
Fedora 44 Update: xorg-x11-server-21.1.23-1.fc44

Name : python-wsgidav
Product : Fedora 43
Version : 4.3.4
Release : 1.fc43
URL : https://github.com/mar10/wsgidav
Summary : Generic and extendable WebDAV server based on WSGI
Description :
A generic and extendable WebDAV server written in Python and based on WSGI.

Main features:

??? WsgiDAV is a stand-alone WebDAV server with SSL support, that can be
installed and run as Python command line script.
??? The python-pam library is needed as extra requirement if pam-login
authentication is used on Linux or OSX.
??? WebDAV is a superset of HTTP, so WsgiDAV is also a performant,
multi-threaded web server with SSL support.
??? WsgiDAV is also a Python library that implements the WSGI protocol and can
be run behind any WSGI compliant web server.
??? WsgiDAV is implemented as a configurable stack of WSGI middleware
applications. Its open architecture allows to extend the functionality and
integrate WebDAV services into your project. Typical use cases are:
??? Expose data structures as virtual, editable file systems.
??? Allow online editing of MS Office documents.
