RHEL 7 : systemd (RHSA-2019:3222)

high Nessus Plugin ID 130377

Synopsis

The remote Red Hat host is missing one or more security updates for systemd.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:3222 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)

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)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL systemd package based on the guidance in RHSA-2019:3222.
