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 . - CVE-2016-4954: Processing spoofed server packets . - CVE-2016-4955: Autokey association reset . - CVE-2016-4956: Broadcast interleave . - CVE-2016-4957: CRYPTO_NAK crash . 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. - Separate the creation of ntp.keys and key #1 in it to avoid problems when upgrading installations that have the file, but no key #1, which is needed e.g. by rcntp addserver.
