"According to the versions of the systemd packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - It was discovered systemd does not correctly check the
    content of PIDFile files before using it to kill
    processes. When a service is run from an unprivileged
    user (e.g. User field set in the service file), a local
    attacker who is able to write to the PIDFile of the
    mentioned service may use this flaw to trick systemd
    into killing other services and/or privileged
    processes. Versions before v237 are
    vulnerable.(CVE-2018-16888)

  - In systemd prior to 234 a race condition exists between
    .mount and .automount units such that automount
    requests from kernel may not be serviced by systemd
    resulting in kernel holding the mountpoint and any
    processes that try to use said mount will hang. A race
    condition like this may lead to denial of service,
    until mount points are unmounted.(CVE-2018-1049)

  - A vulnerability in unit_deserialize of systemd allows
    an attacker to supply arbitrary state across systemd
    re-execution via NotifyAccess. This can be used to
    improperly influence systemd execution and possibly
    lead to root privilege escalation. Affected releases
    are systemd versions up to and including
    239.(CVE-2018-15686)

description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");

  - Fix a remote vulnerability in DHCPv6 in systemd-networkd
    (CVE-2018-15688, #1643362)

  - Downgrade logging of various messages and add loging in
    other places

  - Many many fixes in error handling and minor memory leaks
    and such

  - Fix typos and omissions in documentation

  - Various smaller improvements to unit ordering and
    dependencies

  - Handling of invalid (intentionally corrupt) dbus
    messages is improved, fixing potential local DOS avenues

  - The target of symlinks links in .wants/ and .requires/
    is now ignored. This fixes an issue where the unit file
    would sometimes be loaded from such a symlink, leading
    to non-deterministic unit contents.

  - Filtering of kernel threads is improved. This fixes an
    issues with newer kernels where hybrid kernel/user
    threads are used by bpfilter.

  - Catalog entries for the journal are improved (#1639482)

No need to reboot or log out.

"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.

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)"

"The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has systemd packages installed that are affected
by multiple vulnerabilities:

  - A vulnerability in unit_deserialize of systemd allows an
    attacker to supply arbitrary state across systemd re-
    execution via NotifyAccess. This can be used to
    improperly influence systemd execution and possibly lead
    to root privilege escalation. Affected releases are
    systemd versions up to and including 239.
    (CVE-2018-15686)

  - It was discovered systemd does not correctly check the
    content of PIDFile files before using it to kill
    processes. When a service is run from an unprivileged
    user (e.g. User field set in the service file), a local
    attacker who is able to write to the PIDFile of the
    mentioned service may use this flaw to trick systemd
    into killing other services and/or privileged processes.
    Versions before v237 are vulnerable. (CVE-2018-16888)

  - An out of bounds read was discovered in systemd-journald
    in the way it parses log messages that terminate with a
    colon ':'. A local attacker can use this flaw to
    disclose process memory data. Versions from v221 to v239
    are vulnerable. (CVE-2018-16866)
