| CVE-2013-5211 | 3 Ntp, Opensuse, Oracle | 3 Ntp, Opensuse, Linux | 2026-04-29 | 5.0 MEDIUM | N/A |
| The monlist feature in ntp_request.c in ntpd in NTP before 4.2.7p26 allows remote attackers to cause a denial of service (traffic amplification) via forged (1) REQ_MON_GETLIST or (2) REQ_MON_GETLIST_1 requests, as exploited in the wild in December 2013. | |||||
| CVE-2009-0021 | 1 Ntp | 1 Ntp | 2026-04-23 | 5.0 MEDIUM | N/A |
| NTP 4.2.4 before 4.2.4p5 and 4.2.5 before 4.2.5p150 does not properly check the return value from the OpenSSL EVP_VerifyFinal function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature for DSA and ECDSA keys, a similar vulnerability to CVE-2008-5077. | |||||
| CVE-2009-0159 | 1 Ntp | 1 Ntp | 2026-04-23 | 6.8 MEDIUM | N/A |
| Stack-based buffer overflow in the cookedprint function in ntpq/ntpq.c in ntpq in NTP before 4.2.4p7-RC2 allows remote NTP servers to execute arbitrary code via a crafted response. | |||||
| CVE-2009-3563 | 1 Ntp | 1 Ntp | 2026-04-23 | 6.4 MEDIUM | N/A |
| ntp_request.c in ntpd in NTP before 4.2.4p8, and 4.2.5, allows remote attackers to cause a denial of service (CPU and bandwidth consumption) by using MODE_PRIVATE to send a spoofed (1) request or (2) response packet that triggers a continuous exchange of MODE_PRIVATE error responses between two NTP daemons. | |||||
| CVE-2009-1252 | 1 Ntp | 1 Ntp | 2026-04-23 | 6.8 MEDIUM | N/A |
| Stack-based buffer overflow in the crypto_recv function in ntp_crypto.c in ntpd in NTP before 4.2.4p7 and 4.2.5 before 4.2.5p74, when OpenSSL and autokey are enabled, allows remote attackers to execute arbitrary code via a crafted packet containing an extension field. | |||||
| CVE-2004-0657 | 2 Hp, Ntp | 2 Tru64 Unix, Ntp | 2026-04-16 | 5.0 MEDIUM | N/A |
| Integer overflow in the NTP daemon (NTPd) before 4.0 causes the NTP server to return the wrong date/time offset when a client requests a date/time that is more than 34 years away from the server's time. | |||||
| CVE-2015-7848 | 2 Netapp, Ntp | 6 Clustered Data Ontap, Data Ontap Operating In 7-mode, Oncommand Balance and 3 more | 2025-05-23 | 5.0 MEDIUM | 7.5 HIGH |
| An integer overflow can occur in NTP-dev.4.3.70 leading to an out-of-bounds memory copy operation when processing a specially crafted private mode packet. The crafted packet needs to have the correct message authentication code and a valid timestamp. When processed by the NTP daemon, it leads to an immediate crash. | |||||
| CVE-2020-13817 | 4 Fujitsu, Netapp, Ntp and 1 more | 40 M10-1, M10-1 Firmware, M10-4 and 37 more | 2025-05-05 | 5.8 MEDIUM | 7.4 HIGH |
| ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows remote attackers to cause a denial of service (daemon exit or system time change) by predicting transmit timestamps for use in spoofed packets. The victim must be relying on unauthenticated IPv4 time sources. There must be an off-path attacker who can query time from the victim's ntpd instance. | |||||
| CVE-2020-11868 | 5 Debian, Netapp, Ntp and 2 more | 24 Debian Linux, All Flash Fabric-attached Storage 8300, All Flash Fabric-attached Storage 8300 Firmware and 21 more | 2025-05-05 | 5.0 MEDIUM | 7.5 HIGH |
| ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address, because transmissions are rescheduled even when a packet lacks a valid origin timestamp. | |||||
| 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. | |||||
| CVE-2016-9311 | 1 Ntp | 1 Ntp | 2025-04-20 | 7.1 HIGH | 5.9 MEDIUM |
| 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. | |||||
| CVE-2015-5195 | 5 Canonical, Debian, Fedoraproject and 2 more | 8 Ubuntu Linux, Debian Linux, Fedora and 5 more | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
