CVE-2018-16864

An allocation of memory without limits, that could result in the
stack clashing with another memory region, was discovered in
systemd-journald when many entries are sent to the journal
socket. A local attacker, or a remote one if
systemd-journal-remote is used, may use this flaw to crash
systemd-journald or execute code with journald privileges.

CVE-2018-16865

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.");
