The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:2091 advisory.

    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)

    * systemd: kills privileged process if unprivileged PIDFile was tampered (CVE-2018-16888)
