Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Check Point reports :

... discovered 3 fresh and previously unknown vulnerabilities (CVE-2016-7479, CVE-2016-7480, CVE-2016-7478) in the PHP 7 unserialize mechanism.

The first two vulnerabilities allow attackers to take full control over servers, allowing them to do anything they want with the website, from spreading malware to defacing it or stealing customer data.

The last vulnerability generates a Denial of Service attack which basically hangs the website, exhausts its memory consumption, and shuts it down.

The PHP security team issued fixes for two of the vulnerabilities on the 13th of October and 1st of December.

Solution

Update the affected package.
