| CVE-2009-3563 | 2 Ntp, Redhat | 2 Ntp, Enterprise Linux | 2026-04-23 | 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 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2026-04-23 | 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-2009-0159 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2026-04-23 | 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-2009-0021 | 2 Ntp, Redhat | 2 Ntp, Enterprise Linux | 2026-04-23 | 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-2004-0657 | 2 Hp, Ntp | 2 Tru64 Unix, Ntp | 2026-04-16 | 7.1 High |
| 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 | 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 | 5 Fujitsu, Netapp, Ntp and 2 more | 41 M10-1, M10-1 Firmware, M10-4 and 38 more | 2025-05-05 | 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 | 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-2016-1550 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2025-04-20 | N/A |
| 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-2016-7426 | 4 Canonical, Hpe, Ntp and 1 more | 10 Ubuntu Linux, Hpux-ntp, Ntp and 7 more | 2025-04-20 | 7.5 High |
| NTP before 4.2.8p9 rate limits responses received from the configured sources when rate limiting for all associations is enabled, which allows remote attackers to cause a denial of service (prevent responses from the sources) by sending responses with a spoofed source address. | ||||
| CVE-2016-7428 | 1 Ntp | 1 Ntp | 2025-04-20 | N/A |
| ntpd in NTP before 4.2.8p9 allows remote attackers to cause a denial of service (reject broadcast mode packets) via the poll interval in a broadcast packet. | ||||
| CVE-2016-7433 | 2 Ntp, Redhat | 2 Ntp, Enterprise Linux | 2025-04-20 | N/A |
| NTP before 4.2.8p9 does not properly perform the initial sync calculations, which allows remote attackers to unspecified impact via unknown vectors, related to a "root distance that did not include the peer dispersion." | ||||
| CVE-2017-6452 | 1 Ntp | 1 Ntp | 2025-04-20 | N/A |
| Stack-based buffer overflow in the Windows installer for NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows local users to have unspecified impact via an application path on the command line. | ||||
| CVE-2016-7434 | 2 Hpe, Ntp | 2 Hpux-ntp, Ntp | 2025-04-20 | 7.5 High |
| The read_mru_list function in NTP before 4.2.8p9 allows remote attackers to cause a denial of service (crash) via a crafted mrulist query. | ||||
| CVE-2016-2518 | 7 Debian, Freebsd, Netapp and 4 more | 20 Debian Linux, Freebsd, Clustered Data Ontap and 17 more | 2025-04-20 | 5.3 Medium |
| The MATCH_ASSOC function in NTP before version 4.2.8p9 and 4.3.x before 4.3.92 allows remote attackers to cause an out-of-bounds reference via an addpeer request with a large hmode value. | ||||
| CVE-2015-7853 | 2 Netapp, Ntp | 6 Clustered Data Ontap, Data Ontap, Oncommand Balance and 3 more | 2025-04-20 | 9.8 Critical |
| The datalen parameter in the refclock driver in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to execute arbitrary code or cause a denial of service (crash) via a negative input value. | ||||
| CVE-2016-1551 | 2 Ntp, Ntpsec | 2 Ntp, Ntpsec | 2025-04-20 | N/A |
| 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-2015-7849 | 2 Netapp, Ntp | 6 Clustered Data Ontap, Data Ontap, Oncommand Balance and 3 more | 2025-04-20 | 8.8 High |
| Use-after-free vulnerability in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote authenticated users to possibly execute arbitrary code or cause a denial of service (crash) via crafted packets. | ||||
| CVE-2016-2519 | 1 Ntp | 1 Ntp | 2025-04-20 | N/A |
| ntpd in NTP before 4.2.8p7 and 4.3.x before 4.3.92 allows remote attackers to cause a denial of service (ntpd abort) by a large request data value, which triggers the ctl_getitem function to return a NULL value. | ||||
| CVE-2017-6459 | 1 Ntp | 1 Ntp | 2025-04-20 | N/A |
| The Windows installer for NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows local users to have unspecified impact via vectors related to an argument with multiple null bytes. | ||||
