How to fix?

NVD Description

Note: Versions mentioned in the description apply only to the upstream php5 package and not the php5 package as distributed by Debian. See How to fix? for Debian:8 relevant fixed versions and status.

In all versions of PHP 7, during the unserialization process, resizing the 'properties' hash table of a serialized object may lead to use-after-free. A remote attacker may exploit this bug to gain arbitrary code execution.
