Security Fix(es):

* Multiple flaws were found in the way nettle implemented elliptic curve
scalar multiplication. These flaws could potentially introduce
cryptographic weaknesses into nettle's functionality. (CVE-2015-8803,
CVE-2015-8804, CVE-2015-8805)

* It was found that nettle's RSA and DSA decryption code was vulnerable to
cache-related side channel attacks. An attacker could use this flaw to
recover the private key from a co-located virtual-machine instance.
(CVE-2016-6489)
