"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)

Note that Tenable Network Security has extracted the preceding
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.");

    service (#7526) (bsc#1066156)

    at least one is defined in fstab (bsc#897422)

  - fstab-util: introduce fstab_has_fstype() helper

  - fstab-generator: ignore root=/dev/nfs (#3591)

  - fstab-generator: don't process root= if it happens to be
    'gpt-auto' (#3452)

    apply link config (#7328)

  - Add missing /etc/systemd/network directory

  - Fix parsing of features in detect_vm_xen_dom0 (#7890)
    (bsc#1048510)

    first, and then close the pager (#3550)

"systemd was found to suffer from multiple security vulnerabilities
ranging from denial of service attacks to possible root privilege
escalation.

CVE-2018-1049

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-2018-15686

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.

CVE-2018-15688

A buffer overflow vulnerability in the dhcp6 client of systemd allows
a malicious dhcp6 server to overwrite heap memory in systemd-networkd,
which is not enabled by default in Debian.

For Debian 8 'Jessie', these problems have been fixed in version
215-17+deb8u8.

We recommend that you upgrade your systemd packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."

"According to the versions of the systemd packages installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - An allocation of memory without limits, that could
    result in the stack clashing with another memory
    region, was discovered in systemd-journald when a
    program with long command line arguments calls syslog.
    A local attacker may use this flaw to crash
    systemd-journald or escalate his privileges. Versions
    through v240 are vulnerable.(CVE-2018-16864)

  - An allocation of memory without limits, that could
    result in the stack clashing with another memory
    region, was discovered in systemd-journald when many
    entries are sent to the journal socket. A local
    attacker, or a remote one if systemd-journal-remote is
    used, may use this flaw to crash systemd-journald or
    execute code with journald privileges. Versions through
    v240 are vulnerable.(CVE-2018-16865)

  - An issue was discovered in sd-bus in systemd 239.
    bus_process_object() in libsystemd/sd-bus/bus-objects.c
    allocates a variable-length stack buffer for
    temporarily storing the object path of incoming D-Bus
    messages. An unprivileged local user can exploit this
    by sending a specially crafted message to PID1, causing
    the stack pointer to jump over the stack guard pages
    into an unmapped memory region and trigger a denial of
    service (systemd PID1 crash and kernel
    panic).(CVE-2019-6454)

  - A race condition was found in systemd. This could
    result in automount requests not being serviced and
    processes using them could hang, causing denial of
    service.(CVE-2018-1049)

  - It was discovered that systemd-network does not
    correctly keep track of a buffer size when constructing
    DHCPv6 packets. This flaw may lead to an integer
    underflow that can be used to produce an heap-based
    buffer overflow. A malicious host on the same network
    segment as the victim's one may advertise itself as a
    DHCPv6 server and exploit this flaw to cause a Denial
    of Service or potentially gain code execution on the
    victim's machine.(CVE-2018-15688)
