ntp: ntpd crash when processing config commands with statistics type

It was found that ntpd would exit with a segmentation fault when a statistics type that was not enabled during compilation e.g. timingstats was referenced by the statistics or filegen configuration command...

ntp: incomplete checks in ntp_crypto.c

It was found that the fix for CVE-2014-9750 was incomplete: three issues were found in the value length checks in NTP's ntpcrypto.c, where a packet with particular autokey operations that contained malicious data was not always being completely validated. A remote attacker could use a specially...

FreeBSD : FreeBSD -- Multiple ntp vulnerabilities (7cfcea05-600a-11e6-a6c3-14dae9d210b8)

Multiple vulnerabilities have been discovered in the NTP suite : The fix for Sec 3007 in ntp-4.2.8p7 contained a bug that could cause ntpd to crash. CVE-2016-4957, Reported by Nicolas Edet of Cisco An attacker who knows the origin timestamp and can send a spoofed packet containing a CRYPTO-NAK to...

CVE-2016-4957

ntpd in NTP before 4.2.8p8 allows remote attackers to cause a denial of service daemon crash via a crypto-NAK packet. NOTE: this vulnerability exists because of an incorrect fix for CVE-2016-1547...

CVE-2016-4956

ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service interleaved-mode transition and time change via a spoofed broadcast packet. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-1548...

CVE-2016-4955

ntpd in NTP 4.x before 4.2.8p8, when autokey is enabled, allows remote attackers to cause a denial of service peer-variable clearing and association outage by sending 1 a spoofed crypto-NAK packet or 2 a packet with an incorrect MAC value at a certain time...

Design/Logic Flaw

ntpd in NTP before 4.2.8p8 allows remote attackers to cause a denial of service daemon crash via a crypto-NAK packet. NOTE: this vulnerability exists because of an incorrect fix for CVE-2016-1547...
