   An update that fixes 16 vulnerabilities is now available.

Description:

   This ntp update provides the following security and non security fixes:

   - Update to 4.2.8p4 to fix several security issues (bsc#951608):
     * CVE-2015-7871: NAK to the Future: Symmetric association authentication
       bypass via crypto-NAK
     * CVE-2015-7855: decodenetnum() will ASSERT botch instead of returning
       FAIL on some bogus values
     * CVE-2015-7854: Password Length Memory Corruption Vulnerability
     * CVE-2015-7853: Invalid length data provided by a custom refclock
       driver could cause a buffer overflow
     * CVE-2015-7852 ntpq atoascii() Memory Corruption Vulnerability
     * CVE-2015-7851 saveconfig Directory Traversal Vulnerability
     * CVE-2015-7850 remote config logfile-keyfile
     * CVE-2015-7849 trusted key use-after-free
     * CVE-2015-7848 mode 7 loop counter underrun
     * CVE-2015-7701 Slow memory leak in CRYPTO_ASSOC
     * CVE-2015-7703 configuration directives "pidfile" and "driftfile"
       should only be allowed locally
     * CVE-2015-7704, CVE-2015-7705 Clients that receive a KoD should
       validate the origin timestamp field
     * CVE-2015-7691, CVE-2015-7692, CVE-2015-7702 Incomplete autokey data
       packet length checks
   - Use ntpq instead of deprecated ntpdc in start-ntpd (bnc#936327).
   - Add a controlkey to ntp.conf to make the above work.
   - Improve runtime configuration:
     * Read keytype from ntp.conf
     * Don't write ntp keys to syslog.
   - Don't let "keysdir" lines in ntp.conf trigger the "keys" parser.
   - Fix the comment regarding addserver in ntp.conf (bnc#910063).
   - Remove ntp.1.gz, it wasn't installed anymore.
   - Remove ntp-4.2.7-rh-manpages.tar.gz and only keep ntptime.8.gz. The rest
     is partially irrelevant, partially redundant and potentially outdated
     (bsc#942587).
   - Remove "kod" from the restrict line in ntp.conf (bsc#944300).
   - Use SHA1 instead of MD5 for symmetric keys (bsc#905885).
   - Require perl-Socket6 (bsc#942441).
   - Fix incomplete backporting of "rcntp ntptimemset".
