CVE-2018-16864 is fixed in 14 products on 1 platform, first by libnss-myhostname 237-3ubuntu10.11, released January 10, 2019. It is not reported as exploited. Patch Radar priority: High.
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.
