I'm working on cleaning up this advisory so that it's more informative at a glance. Suggestions are welcome.

This advisory addresses the underlying PHP vulnerabilities behind Dawid Golunski's [CVE-2016-10033][CVE-2016-10033], [CVE-2016-10045][CVE-2016-10045], and [CVE-2016-10074][CVE-2016-10074]. It assumes prior understanding of these vulnerabilities.

This advisory does not yet have associated CVE identifiers.
