These security issues were fixed:
- CVE-2016-4956: Broadcast interleave (bsc#982068).
- CVE-2016-2518: Crafted addpeer with hmode > 7 causes array wraparound
with MATCH_ASSOC (bsc#977457).
- CVE-2016-2519: ctl_getitem() return value not always checked
(bsc#977458).
- 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-2016-4953: Bad authentication demobilizes ephemeral associations
(bsc#982065).
- 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).
This release also contained improved patches for CVE-2015-7704,
CVE-2015-7705, CVE-2015-7974.
These non-security issues were fixed:
- bsc#979302: Change the process name of the forking DNS worker process to
avoid the impression that ntpd is started twice.
- bsc#981422: Don't ignore SIGCHILD because it breaks wait().
- bsc#979981: ntp-wait does not accept fractional seconds, so use 1
instead of 0.2 in ntp-wait.service.
- Separate the creation of ntp.keys and key #1 in it to avoid problems
when upgrading installations that have the file, but no key #1, which is
needed e.g. by 'rcntp addserver'.
- bsc#957226: Restrict the parser in the startup script to the first
occurrance of 'keys' and 'controlkey' in ntp.conf.");
