Several vulnerabilities were discovered
in OpenSSL:

CVE-2016-2177
Guido Vranken discovered that OpenSSL uses undefined pointer
arithmetic.

CVE-2016-2178
Cesar Pereida, Billy Brumley and Yuval Yarom discovered a timing
leak in the DSA code.

CVE-2016-2179 / CVE-2016-2181
Quan Luo and the OCAP audit team discovered denial of service
vulnerabilities in DTLS.

CVE-2016-2180 / CVE-2016-2182 / CVE-2016-6303
Shi Lei discovered an out-of-bounds memory read in
TS_OBJ_print_bio() and an out-of-bounds write in BN_bn2dec()
and MDC2_Update().

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
Shi Lei discovered that missing message length validation when parsing
certificates may potentially result in denial of service.
