Synopsis: Moderate: systemd security, bug fix, and enhancement update
Advisory ID: RHSA-2019:3592-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2019:3592
Issue date: 2019-11-05
CVE Names: CVE-2019-15718
=====================================================================

1. Summary:

An update for systemd is now available for Red Hat Enterprise Linux 8.

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 BaseOS (v. 8) – aarch64, 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: systemd-resolved allows unprivileged users to configure DNS
(CVE-2019-15718)
