How to fix?

Upgrade Ubuntu:16.04 systemd to version 229-4ubuntu21.15 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream systemd package and not the systemd package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

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.
