Summary

The systemd packages contain systemd, a system and service manager for Linux, compatible with the SysV and LSB init scripts. It provides aggressive parallelism capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, and keeps track of processes using Linux cgroups. In addition, it supports snapshotting and restoring of the system state, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic. It can also work as a drop-in replacement for sysvinit.
Security Fix(es):
* systemd: line splitting via fgets() allows for state injection during daemon-reexec (CVE-2018-15686)
* systemd: out-of-bounds read when parsing a crafted syslog message (CVE-2018-16866)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
* Layered slices are left in a "dead" state if slices are stopped that have child slices underneath (BZ#1729227)
