This update for systemd fixes the following issues :

Security issues fixed :

CVE-2018-15688: A buffer overflow vulnerability in the dhcp6 client of systemd allowed a malicious dhcp6 server to overwrite heap memory in systemd-networkd. (bsc#1113632)

CVE-2018-15686: 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.
(bsc#1113665)

Non security issues fixed: dhcp6: split assert_return() to be more debuggable when hit

core: skip unit deserialization and move to the next one when unit_deserialize() fails

core: properly handle deserialization of unknown unit types (#6476)

core: don't create Requires for workdir if 'missing ok' (bsc#1113083)

logind: use manager_get_user_by_pid() where appropriate

logind: rework manager_get_{user|session}_by_pid() a bit

login: fix user@.service case, so we don't allow nested sessions (#8051) (bsc#1112024)

core: be more defensive if we can't determine per-connection socket peer (#7329)

core: introduce systemd.early_core_pattern= kernel cmdline option

core: add missing 'continue' statement

core/mount: fstype may be NULL

journald: don't ship systemd-journald-audit.socket (bsc#1109252)

core: make 'tmpfs' dependencies on swapfs a 'default' dep, not an 'implicit' (bsc#1110445)

mount: make sure we unmount tmpfs mounts before we deactivate swaps (#7076)

detect-virt: do not try to read all of /proc/cpuinfo (bsc#1109197)

emergency: make sure console password agents don't interfere with the emergency shell

man: document that 'nofail' also has an effect on ordering

journald: take leading spaces into account in syslog_parse_identifier

journal: do not remove multiple spaces after identifier in syslog message

syslog: fix segfault in syslog_parse_priority()

journal: fix syslog_parse_identifier()

install: drop left-over debug message (#6913)

Ship systemd-sysv-install helper via the main package This script was part of systemd-sysvinit sub-package but it was wrong since systemd-sysv-install is a script used to redirect enable/disable operations to chkconfig when the unit targets are sysv init scripts.
Therefore it's never been a SySV init tool.

Add udev.no-partlabel-links kernel command-line option. This option can be used to disable the generation of the by-partlabel symlinks regardless of the name used. (bsc#1089761)

man: SystemMaxUse= clarification in journald.conf(5). (bsc#1101040)

systemctl: load unit if needed in 'systemctl is-active' (bsc#1102908)

core: don't freeze OnCalendar= timer units when the clock goes back a lot (bsc#1090944)

Enable or disable machines.target according to the presets (bsc#1107941)

cryptsetup: add support for sector-size= option (fate#325697)

nspawn: always use permission mode 555 for /sys (bsc#1107640)

Bugfix for a race condition between daemon-reload and other commands (bsc#1105031)

Fixes an issue where login with root credentials was not possible in init level 5 (bsc#1091677)

Fix an issue where services of type 'notify' harmless DENIED log entries. (bsc#991901)

Does no longer adjust qgroups on existing subvolumes (bsc#1093753)

cryptsetup: add support for sector-size= option (#9936) (fate#325697 bsc#1114135)

- Fix a local vulnerability from a race condition in     chown-recursive (CVE-2018-15687, #1639076)

  - Fix a local vulnerability from invalid handling of long     lines in state deserialization (CVE-2018-15686,     #1639071)

  - Fix a remote vulnerability in DHCPv6 in systemd-networkd     (CVE-2018-15688, #1639067)

  - The DHCP server is started only when link is UP

  - DHCPv6 prefix delegation is improved

  - 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

  - Typo in %%_environmnentdir rpm macro is fixed (with     backwards compatibility preserved)

  - Matching by MACAddress= in systemd-networkd is fixed

  - Creation of user runtime directories is improved, and     the user manager is only stopped after 10 s after the     user logs out (#1642460 and other bugs)

  - systemd units systemd-timesyncd, systemd-resolved,     systemd-networkd are switched back to use DynamicUser=0

  - Aliases are now resolved when loading modules from pid1.
    This is a (redundant) fix for a brief kernel regression.

  - 'systemctl --wait start' exits immediately if no valid     units are named

  - zram devices are not considered as candidates for     hibernation

  - ECN is not requested for both in- and out-going     connections (the sysctl overide for net.ipv4.tcp_ecn is     removed)

  - Various smaller improvements to unit ordering and     dependencies

  - generators are now called with the manager's environment

  - 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.

  - 'noresume' can be used on the kernel command line to     force normal boot even if a hibernation images is     present

  - Hibernation is not advertised if resume= is not present     on the kernenl command line

  - Hibernation/Suspend/... modes can be disabled using     AllowSuspend=, AllowHibernation=,     AllowSuspendThenHibernate=, AllowHybridSleep=

  - LOGO= and DOCUMENTATION_URL= are documented for the     os-release file

  - The hashmap mempool is now only used internally in     systemd, and is disabled for external users of the     systemd libraries

  - Additional state is serialized/deserialized when logind     is restarted, fixing the handling of user objects

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

  - If suspend fails, the post-suspend hooks are still     called.

  - Various build issues on less-common architectures are     fixed

No need to reboot or log out.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:0049 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: Out-of-bounds heap write in systemd-networkd dhcpv6 option handling (CVE-2018-15688)

    * systemd: stack overflow when calling syslog from a command with long cmdline (CVE-2018-16864)

    * systemd: stack overflow when receiving many journald entries (CVE-2018-16865)

    For more details about the security issue(s), including the impact, a CVSS score, and other related     information, refer to the CVE page(s) listed in the References section.

    Red Hat would like to thank Ubuntu Security Team for reporting CVE-2018-15688 and Qualys Research Labs for     reporting CVE-2018-16864 and CVE-2018-16865. Upstream acknowledges Felix Wilhelm (Google) as the original     reporter of CVE-2018-15688.

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

The remote NewStart CGSL host, running version MAIN 6.06, has NetworkManager packages installed that are affected by multiple vulnerabilities:

  - A buffer overflow vulnerability in the dhcp6 client of systemd allows a malicious dhcp6 server to     overwrite heap memory in systemd-networkd. Affected releases are systemd: versions up to and including     239. (CVE-2018-15688)

  - Incomplete blacklist vulnerability in the svEscape function in settings/plugins/ifcfg-rh/shvar.c in the     ifcfg-rh plug-in for GNOME NetworkManager 0.9.1, 0.9.0, 0.8.1, and possibly other versions, when PolicyKit     is configured to allow users to create new connections, allows local users to execute arbitrary commands     via a newline character in the name for a new network connection, which is not properly handled when     writing to the ifcfg file. (CVE-2011-3364)

  - nm-applet.conf in GNOME NetworkManager before 0.7.0.99 contains an incorrect deny setting, which allows     local users to discover (1) network connection passwords and (2) pre-shared keys via calls to the     GetSecrets method in the dbus request handler. (CVE-2009-0365)

  - GNOME NetworkManager before 0.7.0.99 does not properly verify privileges for dbus (1) modify and (2)     delete requests, which allows local users to change or remove the network connections of arbitrary users     via unspecified vectors related to org.freedesktop.NetworkManagerUserSettings and at_console.
    (CVE-2009-0578)

  - DBus-GLib 0.73 disregards the access flag of exported GObject properties, which allows local users to     bypass intended access restrictions and possibly cause a denial of service by modifying properties, as     demonstrated by properties of the (1) DeviceKit-Power, (2) NetworkManager, and (3) ModemManager services.
    (CVE-2010-1172)
