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-2009-3563 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-2009-0021 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-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-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-2015-7871 3 Debian, Netapp, Ntp 7 Debian Linux, Clustered Data Ontap, Data Ontap and 4 more 2025-04-20 9.8 Critical
Crypto-NAK packets in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to bypass authentication.
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-2015-8140 1 Ntp 1 Ntp 2025-04-20 N/A
The ntpq protocol in NTP before 4.2.8p7 allows remote attackers to conduct replay attacks by sniffing the network.
CVE-2015-5300 7 Canonical, Debian, Fedoraproject and 4 more 21 Ubuntu Linux, Debian Linux, Fedora and 18 more 2025-04-20 N/A
The panic_gate check in NTP before 4.2.8p5 is only re-enabled after the first change to the system clock that was greater than 128 milliseconds by default, which allows remote attackers to set NTP to an arbitrary time when started with the -g option, or to alter the time by up to 900 seconds otherwise by responding to an unspecified number of requests from trusted sources, and leveraging a resulting denial of service (abort and restart).
CVE-2016-7431 1 Ntp 1 Ntp 2025-04-20 N/A
NTP before 4.2.8p9 allows remote attackers to bypass the origin timestamp protection mechanism via an origin timestamp of zero. NOTE: this vulnerability exists because of a CVE-2015-8138 regression.
CVE-2016-9311 2 Ntp, Redhat 2 Ntp, Enterprise Linux 2025-04-20 N/A
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-2015-7975 1 Ntp 1 Ntp 2025-04-20 N/A
The nextvar function in NTP before 4.2.8p6 and 4.3.x before 4.3.90 does not properly validate the length of its input, which allows an attacker to cause a denial of service (application crash).
CVE-2015-8139 1 Ntp 1 Ntp 2025-04-20 N/A
ntpq in NTP before 4.2.8p7 allows remote attackers to obtain origin timestamps and then impersonate peers via unspecified vectors.
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.
CVE-2015-7854 2 Netapp, Ntp 6 Clustered Data Ontap, Data Ontap, Oncommand Balance and 3 more 2025-04-20 8.8 High
Buffer overflow in the password management functionality in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote authenticated users to cause a denial of service (daemon crash) or possibly execute arbitrary code via a crafted key file.
CVE-2017-6455 1 Ntp 1 Ntp 2025-04-20 N/A
NTP before 4.2.8p10 and 4.3.x before 4.3.94, when using PPSAPI, allows local users to gain privileges via a DLL in the PPSAPI_DLLS environment variable.
CVE-2016-9312 2 Microsoft, Ntp 2 Windows, Ntp 2025-04-20 N/A
ntpd in NTP before 4.2.8p9, when running on Windows, allows remote attackers to cause a denial of service via a large UDP packet.
