Oracle Linux 7 : systemd (ELSA-2016-2610)

This script is Copyright (C) 2016 Tenable Network Security, Inc.


Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2016:2610 :

An update for systemd is now available for Red Hat Enterprise Linux 7.

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.

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) :

* A flaw was found in the way systemd handled empty notification
messages. A local attacker could use this flaw to make systemd freeze
its execution, preventing further management of system services,
system shutdown, or zombie process collection via systemd.
(CVE-2016-7795)

Bug Fix(es) :

* Previously, the udev device manager automatically enabled all memory
banks on IBM z System installations. As a consequence, hot plug memory
was enabled automatically, which was incorrect. With this update,
system architecture checks have been added to the udev rules to
address the problem. As a result, hot plug memory is no longer
automatically enabled. (BZ#1381123)
