An update that solves 16 vulnerabilities can now be installed.

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 The rest is partially irrelevant, partially redundant and potentially outdated (bsc#942587).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".
