CVE-2016-2183 
DES-based cipher suites are demoted from the HIGH group to MEDIUM
as a mitigation for the SWEET32 attack.

CVE-2016-6302 
Shi Lei discovered that the use of SHA512 in TLS session tickets
is susceptible to denial of service.

CVE-2016-6304 
Shi Lei discovered that excessively large OCSP status request may
result in denial of service via memory exhaustion.

CVE-2016-6306
