    Description:

    ntp was updated to version 4.2.8p8 to fix five security issues.

    These security issues were fixed:
    - CVE-2016-4953: Bad authentication demobilizes ephemeral associations
    (bsc#982065).
    - CVE-2016-4954: Processing spoofed server packets (bsc#982066).
    - CVE-2016-4955: Autokey association reset (bsc#982067).
    - CVE-2016-4956: Broadcast interleave (bsc#982068).
    - CVE-2016-4957: CRYPTO_NAK crash (bsc#982064).

    These non-security issues were fixed:
    - Keep the parent process alive until the daemon has finished
    initialisation, to make sure that the PID file exists when the parent
    returns.
    - 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().
