  (bsc#937837)

  These security issues were fixed:

  - CVE-2015-8158: Fixed potential infinite loop in ntpq (bsc#962966).

  - CVE-2015-8138: Zero Origin Timestamp Bypass (bsc#963002).

  - CVE-2015-7979: Off-path Denial of Service (DoS) attack on authenticated
  broadcast mode (bsc#962784).

  - CVE-2015-7978: Stack exhaustion in recursive traversal of restriction
  list (bsc#963000).

  - CVE-2015-7977: reslist NULL pointer dereference (bsc#962970).

  - CVE-2015-7976: ntpq saveconfig command allows dangerous characters in
  filenames (bsc#962802).

  - CVE-2015-7975: nextvar() missing length check (bsc#962988).

  - CVE-2015-7974: Skeleton Key: Missing key check allows impersonation
  between authenticated peers (bsc#962960).

  - CVE-2015-7973: Replay attack on authenticated broadcast mode
  (bsc#962995).

  - CVE-2015-8140: ntpq vulnerable to replay attacks (bsc#962994).

  - CVE-2015-8139: Origin Leak: ntpq and ntpdc, disclose origin (bsc#962997).

  - CVE-2015-5300: MITM attacker could have forced ntpd to make a step
  larger than the panic threshold (bsc#951629).

  These non-security issues were fixed:

  - fate#320758 bsc#975981: Enable compile-time support for MS-SNTP
  (--enable-ntp-signd).  This replaces the w32 patches in 4.2.4 that added
  the authreg directive.

  - bsc#962318: Call /usr/sbin/sntp with full path to synchronize in
  start-ntpd. When run as cron job, /usr/sbin/ is not in the path, which
  caused the synchronization to fail.

  - bsc#782060: Speedup ntpq.

  - bsc#916617: Add /var/db/ntp-kod.

  - bsc#956773: Add ntp-ENOBUFS.patch to limit a warning that might happen
  quite a lot on loaded systems.

  - bsc#951559, bsc#975496: Fix the TZ offset output of sntp during DST.

  - Add ntp-fork.patch and build with threads disabled to allow name
  resolution even when running chrooted.
