Summary: An update for systemd is now available for Red Hat Enterprise Linux 7.4 Advanced Update Support, Red Hat Enterprise Linux 7.4 Telco Extended Update Support, and Red Hat Enterprise Linux 7.4 Update Services for SAP Solutions. 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 Server AUS (v. 7.4) - x86_64 Red Hat Enterprise Linux Server E4S (v. 7.4) - ppc64le, x86_64 Red Hat Enterprise Linux Server Optional AUS (v. 7.4) - x86_64 Red Hat Enterprise Linux Server Optional E4S (v. 7.4) - ppc64le, x86_64 Red Hat Enterprise Linux Server Optional TUS (v. 7.4) - x86_64 Red Hat Enterprise Linux Server TUS (v. 7.4) - 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. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 5.
