Advisory ID:       RHSA-2019:3222-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2019:3222

CVE Names:         CVE-2018-15686 CVE-2018-16866 
=====================================================================

1. Summary:

An update for systemd is now available for Red Hat Enterprise Linux 7.6
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. 7.6) - x86_64
Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.6) - x86_64
Red Hat Enterprise Linux Server EUS (v. 7.6) - ppc64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux Server Optional EUS (v. 7.6) - 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):

* Layered slices are left in a "dead" state if slices are stopped that have
child slices underneath (BZ#1729227)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

5. Bugs fixed (https://bugzilla.redhat.com/):

1639071 - CVE-2018-15686 systemd: line splitting via fgets() allows for state injection during daemon-reexec
1653867 - CVE-2018-16866 systemd: out-of-bounds read when parsing a crafted syslog message
