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().
