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 out of bounds read was discovered in systemd-journald in the way it parses log messages that terminate with a colon ':'. A local attacker can use this flaw to disclose process memory data. Versions from v221 to v239 are vulnerable.
