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 Red Hat Enterprise Linux Server Optional 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: 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)
