| CVE-2015-7855 | 4 Debian, Netapp, Ntp and 1 more | 11 Debian Linux, Clustered Data Ontap, Data Ontap and 8 more | 2025-04-20 | 4.0 MEDIUM | 6.5 MEDIUM |
| The decodenetnum function in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service (assertion failure) via a 6 or mode 7 packet containing a long data value. | |||||
| CVE-2016-2516 | 1 Ntp | 1 Ntp | 2025-04-20 | 7.1 HIGH | 5.3 MEDIUM |
| NTP before 4.2.8p7 and 4.3.x before 4.3.92, when mode7 is enabled, allows remote attackers to cause a denial of service (ntpd abort) by using the same IP address multiple times in an unconfig directive. | |||||
| CVE-2015-7703 | 5 Debian, Netapp, Ntp and 2 more | 13 Debian Linux, Clustered Data Ontap, Data Ontap and 10 more | 2025-04-20 | 4.3 MEDIUM | 7.5 HIGH |
| The "pidfile" or "driftfile" directives in NTP ntpd 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77, when ntpd is configured to allow remote configuration, allows remote attackers with an IP address that is allowed to send configuration requests, and with knowledge of the remote configuration password to write to arbitrary files via the :config command. | |||||
| CVE-2016-1551 | 2 Ntp, Ntpsec | 2 Ntp, Ntpsec | 2025-04-20 | 2.6 LOW | 3.7 LOW |
| ntpd in NTP 4.2.8p3 and NTPsec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 relies on the underlying operating system to protect it from requests that impersonate reference clocks. Because reference clocks are treated like other peers and stored in the same structure, any packet with a source ip address of a reference clock (127.127.1.1 for example) that reaches the receive() function will match that reference clock's peer record and will be treated as a trusted peer. Any system that lacks the typical martian packet filtering which would block these packets is in danger of having its time controlled by an attacker. | |||||
| CVE-2015-8139 | 1 Ntp | 1 Ntp | 2025-04-20 | 5.0 MEDIUM | 5.3 MEDIUM |
| ntpq in NTP before 4.2.8p7 allows remote attackers to obtain origin timestamps and then impersonate peers via unspecified vectors. | |||||

| ntpd in NTP before 4.2.8p9, when the trap service is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted packet. | |||||
| CVE-2015-7702 | 5 Debian, Netapp, Ntp and 2 more | 13 Debian Linux, Clustered Data Ontap, Data Ontap and 10 more | 2025-04-20 | 4.0 MEDIUM | 6.5 MEDIUM |
| The crypto_xmit function in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service (crash). NOTE: This vulnerability exists due to an incomplete fix for CVE-2014-9750. | |||||
| CVE-2017-6462 | 1 Ntp | 1 Ntp | 2025-04-20 | 4.6 MEDIUM | 7.8 HIGH |
| Buffer overflow in the legacy Datum Programmable Time Server (DPTS) refclock driver in NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows local users to have unspecified impact via a crafted /dev/datum device. | |||||
| CVE-2016-2517 | 1 Ntp | 1 Ntp | 2025-04-20 | 4.9 MEDIUM | 5.3 MEDIUM |
| NTP before 4.2.8p7 and 4.3.x before 4.3.92 allows remote attackers to cause a denial of service (prevent subsequent authentication) by leveraging knowledge of the controlkey or requestkey and sending a crafted packet to ntpd, which changes the value of trustedkey, controlkey, or requestkey. NOTE: this vulnerability exists because of a CVE-2016-2516 regression. | |||||
| CVE-2016-1550 | 1 Ntp | 1 Ntp | 2025-04-20 | 5.0 MEDIUM | 5.3 MEDIUM |
| An exploitable vulnerability exists in the message authentication functionality of libntp in ntp 4.2.8p4 and NTPSec a5fb34b9cc89b92a8fef2f459004865c93bb7f92. An attacker can send a series of crafted messages to attempt to recover the message digest key. | |||||

| ntp_openssl.m4 in ntpd in NTP before 4.2.7p112 allows remote attackers to cause a denial of service (segmentation fault) via a crafted statistics or filegen configuration command that is not enabled during compilation. | |||||
| CVE-2015-5146 | 3 Debian, Fedoraproject, Ntp | 3 Debian Linux, Fedora, Ntp | 2025-04-20 | 3.5 LOW | 5.3 MEDIUM |
| ntpd in ntp before 4.2.8p3 with remote configuration enabled allows remote authenticated users with knowledge of the configuration password and access to a computer entrusted to perform remote configuration to cause a denial of service (service crash) via a NULL byte in a crafted configuration directive packet. | |||||
