See also CVE-2016-7032 This alert mentions a seccomp-based filter. If we decide to backport that filter for this CVE, and CVE-2016-7032, then 'medium' may continue to be appropriate. If we decide the seccomp-based filter is not suitable for a backport, then perhaps 'negligible' would be appropriate.
