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-2009-3563 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-2009-0021 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-2016-7427 1 Ntp 1 Ntp 2025-04-20 N/A
The broadcast mode replay prevention functionality in ntpd in NTP before 4.2.8p9 allows remote attackers to cause a denial of service (reject broadcast mode packets) via a crafted broadcast mode packet.
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-2015-8138 2 Ntp, Redhat 2 Ntp, Enterprise Linux 2025-04-20 N/A
NTP before 4.2.8p6 and 4.3.x before 4.3.90 allows remote attackers to bypass the origin timestamp validation via a packet with an origin timestamp set to zero.
CVE-2017-6464 2 Ntp, Redhat 2 Ntp, Enterprise Linux 2025-04-20 N/A
NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows remote attackers to cause a denial of service (ntpd crash) via a malformed mode configuration directive.
CVE-2015-7852 5 Debian, Netapp, Ntp and 2 more 15 Debian Linux, Clustered Data Ontap, Data Ontap and 12 more 2025-04-20 5.9 Medium
ntpq 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) via crafted mode 6 response packets.
CVE-2016-7429 2 Ntp, Redhat 2 Ntp, Enterprise Linux 2025-04-20 N/A
NTP before 4.2.8p9 changes the peer structure to the interface it receives the response from a source, which allows remote attackers to cause a denial of service (prevent communication with a source) by sending a response for a source to an interface the source does not use.
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-2017-6458 4 Apple, Hpe, Ntp and 1 more 5 Mac Os X, Hpux-ntp, Ntp and 2 more 2025-04-20 8.8 High
Multiple buffer overflows in the ctl_put* functions in NTP before 4.2.8p10 and 4.3.x before 4.3.94 allow remote authenticated users to have unspecified impact via a long variable.
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-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-2016-9310 2 Ntp, Redhat 2 Ntp, Enterprise Linux 2025-04-20 N/A
The control mode (mode 6) functionality in ntpd in NTP before 4.2.8p9 allows remote attackers to set or unset traps via a crafted control mode packet.
CVE-2017-6451 1 Ntp 1 Ntp 2025-04-20 N/A
The mx4200_send function in the legacy MX4200 refclock in NTP before 4.2.8p10 and 4.3.x before 4.3.94 does not properly handle the return value of the snprintf function, which allows local users to execute arbitrary code via unspecified vectors, which trigger an out-of-bounds memory write.
