-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2019-7322053e74 2019-04-29 01:40:59.966408 --------------------------------------------------------------------------------
Name : systemd Product : Fedora 30 Version : 241 Release : 8.git9ef65cb.fc30 URL : https://www.freedesktop.org/wiki/Software/systemd Summary : System and Service Manager Description : systemd is a system and service manager that runs as PID 1 and starts the rest of the system. It provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux control groups, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic. systemd supports SysV and LSB init scripts and works as a replacement for sysvinit. Other parts of this package are a logging daemon, utilities to control basic system configuration like the hostname, date, locale, maintain a list of logged-in users, system accounts, runtime directories and settings, and daemons to manage simple network configuration, network time synchronization, log forwarding, and name resolution.
This package was built from the 241-stable branch of systemd, commit https://github.com/systemd/systemd-stable/commit/9ef65cb.
-------------------------------------------------------------------------------- Update Information:
- Fix hang in flush_accept (#1702358) - Fix handling of RUN keys in udevd - Some documentation and minor logging fixes - Backport the addition of RestrictSUIDSGID= from systemd-242 and enable RestrictSUIDSGID=yes for systemd services which use DynamicUser=yes (#1703356, CVE-2019-3843). The defaults in v242 were changed to enable RestrictSUIDSGID=yes if DynamicUser=yes is specified, but this backport doesn't do this and RestrictSUIDSGID=yes has to be requested explicitly. Maintainers of other services packages for Fedora should consider doing this. No need to log out or reboot. -------------------------------------------------------------------------------- ChangeLog:
