{"schemaVersion":3,"id":"SUSE-SU-2016:1311-1","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Security update for ntp\n\n\nThis network time protocol server ntp was updated to 4.2.8p6 to fix the following\nissues:\n\nAlso yast2-ntp-client was updated to match some sntp syntax changes. (bsc#937837)\n\nMajor functional changes:\n- The 'sntp' commandline tool changed its option handling in a major way.\n- 'controlkey 1' is added during update to ntp.conf to allow sntp to work.\n- The local clock is being disabled during update.\n- ntpd is no longer running chrooted.\n\n\nOther functional changes:\n- ntp-signd is installed.\n- 'enable mode7' can be added to the configuration to allow ntdpc to work as compatibility mode option.\n- 'kod' was removed from the default restrictions.\n- SHA1 keys are used by default instead of MD5 keys.\n\nThese security issues were fixed:\n- CVE-2015-5219: An endless loop due to incorrect precision to double conversion (bsc#943216).\n- CVE-2015-8158: Fixed potential infinite loop in ntpq (bsc#962966).\n- CVE-2015-8138: Zero Origin

CVE-2015-7691, CVE-2015-7692, CVE-2015-7702: Incomplete autokey data packet length checks (bsc#951608).\n\nThese non-security issues were fixed:\n- fate#320758 bsc#975981: Enable compile-time support for MS-SNTP (--enable-ntp-signd).\n  This replaces the w32 patches in 4.2.4 that added the authreg\n  directive.\n- bsc#962318: Call /usr/sbin/sntp with full path to synchronize in start-ntpd.\n  When run as cron job, /usr/sbin/ is not in the path, which caused\n  the synchronization to fail.\n- bsc#782060: Speedup ntpq.\n- bsc#916617: Add /var/db/ntp-kod.\n- bsc#956773: Add ntp-ENOBUFS.patch to limit a warning that might happen quite a lot on loaded systems.\n- bsc#951559,bsc#975496: Fix the TZ offset output of sntp during DST.\n- Add ntp-fork.patch and build with threads disabled to allow name resolution even when running chrooted.\n- Add a controlkey line to /etc/ntp.conf if one does not already exist to allow runtime configuuration via ntpq.\n- bsc#946386: Temporarily disable memlock to avoid problems due to high memory usage during name resolution.\n- bsc#905885: Use SHA1 instead of MD5 for symmetric keys.\n- Improve runtime configuration:\n  * Read keytype from ntp.conf\n  * Don't write ntp keys to syslog.\n- Fix legacy action scripts to pass on command line arguments.\n- bsc#944300: Remove 'kod' from the restrict line in ntp.conf.\n- bsc#936327: Use ntpq instead of deprecated ntpdc in start-ntpd.\n- Don't let 'keysdir' lines in ntp.conf trigger the 'keys' parser.\n- Disable mode 7 (ntpdc) again, now that we don't use it anymore.\n- Add 'addserver' as a new legacy action.\n- bsc#910063: Fix the comment regarding addserver in ntp.conf.\n- bsc#926510: Disable chroot by default.\n- bsc#920238: Enable ntpdc for backwards compatibility.\n- bsc#784760: Remove local clock from default configuration.\n- bsc#942441/fate#319496: Require perl-Socket6.\n- Improve runtime configuration:\n  * Read keytype from ntp.conf\n  * Don't write ntp keys to syslog.\n-
