Nettle is a cryptographic library that is designed to fit easily in almost any context: In cryptographic toolkits for object-oriented languages, such as C++, Python, or Pike, in applications like lsh or GnuPG, or even in kernel space.
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)
Additional Changes:
