Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS

Summary:

systemd could be made to crash if it received specially a crafted D-Bus message.

Software Description: - systemd: system and service manager

Details:

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).

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.10:
libsystemd0 239-7ubuntu10.8
systemd 239-7ubuntu10.8

Ubuntu 18.04 LTS:
libsystemd0 237-3ubuntu10.13
systemd 237-3ubuntu10.13

Ubuntu 16.04 LTS:
libsystemd0 229-4ubuntu21.16
systemd 229-4ubuntu21.16

After a standard system update you need to reboot your computer to make all the necessary changes.
