Ubuntu Security Notice USN-3193-1: Posted Feb 6, 2017; Authored by Ubuntu | Site security.ubuntu.com; Ubuntu Security Notice 3193-1 - It was discovered that Nettle incorrectly mitigated certain timing side-channel attacks. A remote attacker could possibly use this flaw to recover private keys.; tags | advisory, remote; systems | linux, ubuntu; advisories | CVE-2016-6489; SHA-256 | c99d17b3cb1a2dada1c04033fbb63bba3e4fad5be7282f2c74817a38efe879fb; Download | Favorite | View

Red Hat Security Advisory 2016-2582-02: Posted Nov 3, 2016; Authored by Red Hat | Site access.redhat.com; Red Hat Security Advisory 2016-2582-02 - 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: Multiple flaws were found in the way nettle implemented elliptic curve scalar multiplication. These flaws could potentially introduce cryptographic weaknesses into nettle's functionality.; tags | advisory, kernel, python; systems | linux, redhat; advisories | CVE-2015-8803, CVE-2015-8804, CVE-2015-8805, CVE-2016-6489; SHA-256 | e5dfca04374bb6d08b4923e98d607077727bd94ebabbe338b9888f47ba0f959f; Download | Favorite | View
