USN-6841-1 fixed a vulnerability in PHP. This update provides the
corresponding updates for Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.
Original advisory details:
It was discovered that PHP could early return in the filter_var function
resulting in invalid user information being treated as valid user
information. An attacker could possibly use this issue to expose raw
user input information.
