    1. Summary:
    
    An update for systemd is now available for Red Hat Enterprise Linux 7.5
    Extended Update Support.
    
    Red Hat Product Security has rated this update as having a security impact
    of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
    gives a detailed severity rating, is available for each vulnerability from
    the CVE link(s) in the References section.
    
    2. Relevant releases/architectures:
    
    Red Hat Enterprise Linux ComputeNode EUS (v. 7.5) - x86_64
    Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.5) - x86_64
    Red Hat Enterprise Linux Server EUS (v. 7.5) - ppc64, ppc64le, s390x, x86_64

    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: 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):
    
    * Restarting systemd-journald to load new configurations causes other
    daemons stop working (BZ#1798160)
