None of these exploits have anything to do with accessing TCP services using a browser. The only exploit there having anything to do with Safari, CVE-2016-4657, is a WebKit memory corruption (per your [1]: "The stage1 employs a previously undocumented memory corruption vulnerability in WebKit to execute this code within the context of the Safari browser (CVE-2016-4657).").
