"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 Important. 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.

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: stack overflow when calling syslog from a command with long
cmdline (CVE-2018-16864)

* systemd: stack overflow when receiving many journald entries
(CVE-2018-16865)

For more details about the security issue(s), including the impact, a
CVSS score, and other related information, refer to the CVE page(s)
listed in the References section.

Red Hat would like to thank Qualys Research Labs for reporting these
issues."
