   An update that solves 5 vulnerabilities and has three fixes
   is now available.

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().
