for certain message fields on the stack. A local attacker could
potentially exploit this to cause a denial of service, or execute
arbitrary code. (CVE-2018-16864)
It was discovered that systemd-journald allocated variable-length arrays
of objects representing message fields on the stack. A local attacker
could potentially exploit this to cause a denial of service, or execute
arbitrary code. (CVE-2018-16865)
An out-of-bounds read was discovered in systemd-journald. A local
