{"schemaVersion":3,"id":"SUSE-SU-2016:1568-1","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Security update for ntp\n\nntp was updated to version 4.2.8p8 to fix 17 security issues.\n\nThese security issues were fixed:\n- CVE-2016-4956: Broadcast interleave (bsc#982068).\n- CVE-2016-2518: Crafted addpeer with hmode > 7 causes array wraparound with MATCH_ASSOC (bsc#977457).\n- CVE-2016-2519: ctl_getitem() return value not always checked (bsc#977458).\n- CVE-2016-4954: Processing spoofed server packets (bsc#982066).\n- CVE-2016-4955: Autokey association reset (bsc#982067).\n- CVE-2015-7974: NTP did not verify peer associations of symmetric keys when authenticating packets, which might allowed remote attackers to conduct impersonation attacks via an arbitrary trusted key, aka a 'skeleton key (bsc#962960).\n- CVE-2016-4957: CRYPTO_NAK crash (bsc#982064).\n- CVE-2016-2516: Duplicate IPs on unconfig directives will cause an assertion botch (bsc#977452).\n- CVE-2016-2517: Remote configuration trustedkey/requestkey values are not properly validated (bsc#977455).\n- CVE-2016-4953: Bad authentication demobilizes ephemeral associations (bsc#982065).\n- CVE-2016-1547: CRYPTO-NAK DoS (bsc#977459).\n- CVE-2016-1551: Refclock impersonation vulnerability, AKA: refclock-peering (bsc#977450).\n- CVE-2016-1550: Improve NTP security against buffer comparison timing attacks, authdecrypt-timing, AKA: authdecrypt-timing (bsc#977464).\n- CVE-2016-1548: Interleave-pivot - MITIGATION ONLY (bsc#977461).\n- CVE-2016-1549: Sybil vulnerability: ephemeral association attack, AKA: ntp-sybil - MITIGATION ONLY (bsc#977451).\n\nThis release also contained improved patches for CVE-2015-7704, CVE-2015-7705, CVE-2015-7974.\n\nThese non-security issues were fixed:\n- bsc#979302: Change the process name of the forking DNS worker process to avoid the impression that ntpd is started twice.\n- bsc#981422: Don't ignore SIGCHILD because it breaks wait().\n- bsc#979981: ntp-wait does not accept fractional seconds, so use 1 instead of 0.2 in ntp-wait.service.\n- 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'.\n- bsc#957226: Restrict the parser in the startup script to the first occurrance of 'keys' and 'controlkey' in ntp.conf.","dates":{"published":"2016-06-14T06:45:46.000Z","modified":"2026-02-04T02:54:59.789Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"suse","product":"ntp&distro=SUSE
