CVE-2016-4954: Processing spoofed server packets (bsc#982066).
CVE-2016-4955: Autokey association reset (bsc#982067).
CVE-2015-7974: NTP did not verify peer associations of symmetric keys when authenticating packets, which might allowed remote attackers to conduct impersonation attacks via an arbitrary trusted key, aka a 'skeleton key (bsc#962960).
CVE-2016-4957: CRYPTO_NAK crash (bsc#982064).
CVE-2016-2516: Duplicate IPs on unconfig directives will cause an assertion botch (bsc#977452).
CVE-2016-2517: Remote configuration trustedkey/requestkey values are not properly validated (bsc#977455).

CVE-2016-1547: CRYPTO-NAK DoS (bsc#977459).
CVE-2016-1551: Refclock impersonation vulnerability, AKA: refclock-peering (bsc#977450).
CVE-2016-1550: Improve NTP security against buffer comparison timing attacks, authdecrypt-timing, AKA:
authdecrypt-timing (bsc#977464).
CVE-2016-1548: Interleave-pivot - MITIGATION ONLY (bsc#977461).
CVE-2016-1549: Sybil vulnerability: ephemeral association attack, AKA: ntp-sybil - MITIGATION ONLY (bsc#977451).
