Use CVE-2016-9642.

Incidentally, the published WebKit policy is apparently "We cannot
guarantee a prompt human response to every security bug filed. If you
would like immediate feedback on a security issue, or would like to
discuss details with members of the WebKit Security Group, please
email security@...kit.org and include a link to the relevant Bugzilla
bug. Your message will be acknowledged within a week at most." on the
https://webkit.org/security-policy/ web page.
