attacker could possibly use this issue to cause PHP to crash, resulting in a
denial of service. This issue only affected Ubuntu 16.04 LTS. (CVE-2019-9022)

It was discovered that PHP incorrectly handled mbstring regular expressions. A
remote attacker could possibly use this issue to cause PHP to crash, resulting
in a denial of service. (CVE-2019-9023)
