| CVE-2015-7705 | Cri | 0.66 | 9.8 | 0.31 | | Aug 7, 2017 | The rate limiting feature in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to have unspecified impact via a large number of crafted requests. |
| CVE-2015-7974 | Hig | 0.51 | 7.7 | 0.11 | | Jan 26, 2016 | NTP 4.x before 4.2.8p6 and 4.3.x before 4.3.90 do not verify peer associations of symmetric keys when authenticating packets, which might allow remote attackers to conduct impersonation attacks via an arbitrary trusted key, aka a "skeleton key." |
| 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. |
