3. Description:

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-resolved: use-after-free when dealing with DnsStream in
resolved-dns-stream.c (CVE-2022-2526)
