Security vulnerability fixed :

CVE-2019-6454: Fixed a crash of PID1 by sending specially crafted D-BUS message on the system bus by an unprivileged user (bsc#1125352)

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

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3891-1 advisory.

    It was discovered that systemd incorrectly handled certain D-Bus messages. A local unprivileged attacker     could exploit this in order to crash the init process, resulting in a system denial-of-service (kernel     panic).

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

- Prevent buffer overread in systemd-udevd

  - Properly validate dbus paths received over dbus     (#1678394, CVE-2019-6454)

No need to log out or reboot.

An update of the systemd package has been released.

The remote CentOS Linux 8 host has packages installed that are affected by a vulnerability as referenced in the CESA-2019:0990 advisory.

  - systemd: Insufficient input validation in bus_process_object() resulting in PID 1 crash (CVE-2019-6454)

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

Chris Coulson discovered a flaw in systemd leading to denial of service. An unprivileged user could take advantage of this issue to crash PID1 by sending a specially crafted D-Bus message on the system bus.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2019:0368 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: Insufficient input validation in bus_process_object() resulting in PID 1 crash (CVE-2019-6454)

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

  - A memory leak was discovered in the backport of fixes     for CVE-2018-16864 in Red Hat Enterprise Linux. Function     dispatch_message_real() in journald-server.c does not     free the memory allocated by set_iovec_field_free() to     store the `_CMDLINE=` entry. A local attacker may use     this flaw to make systemd-journald crash.
    (CVE-2019-3815)

  - It was discovered that systemd allocates a buffer large     enough to store the path field of a dbus message without     performing enough checks. A local attacker may trigger     this flaw by sending a dbus message to systemd with a     large path making systemd crash or possibly elevating     his privileges. (CVE-2019-6454)
