"ntp was updated to version 4.2.8p6 to fix 12 security issues.

Also yast2-ntp-client was updated to match some sntp syntax changes.
(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.
