"It was discovered that PHP incorrectly handled the PHAR 404 error
page. A remote attacker could possibly use this issue to conduct
cross-site scripting (XSS) attacks. (CVE-2018-5712)

It was discovered that PHP incorrectly handled memory when
unserializing certain data. A remote attacker could use this issue to
cause PHP to crash, resulting in a denial of service, or possibly
execute arbitrary code. (CVE-2017-12933)

It was discovered that PHP incorrectly handled 'front of' and 'back
of' date directives. A remote attacker could possibly use this issue
to obtain sensitive information. (CVE-2017-16642).

description block directly from the Ubuntu security advisory. Tenable
