| CVE-2017-6458 | Hig | 0.58 | 8.8 | 0.11 | | Mar 27, 2017 | Multiple buffer overflows in the ctl_put* functions in NTP before 4.2.8p10 and 4.3.x before 4.3.94 allow remote authenticated users to have unspecified impact via a long variable. |
| CVE-2016-4953 | Hig | 0.50 | 7.5 | 0.14 | | Jul 5, 2016 | ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (ephemeral-association demobilization) by sending a spoofed crypto-NAK packet with incorrect authentication data at a certain time. |
| CVE-2016-4954 | Hig | 0.49 | 7.5 | 0.05 | | Jul 5, 2016 | The process_packet function in ntp_proto.c in ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (peer-variable modification) by sending spoofed packets from many source IP addresses in a certain scenario, as demonstrated by triggering an incorrect leap indication. |
| CVE-2016-4955 | Med | 0.38 | 5.9 | 0.02 | | Jul 5, 2016 | 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. |
| CVE-2016-4956 | Med | 0.35 | 5.3 | 0.01 | | Jul 5, 2016 | 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. |
