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-2016-1551 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.

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-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-2016-2516 1 Ntp 1 Ntp 2025-04-20 N/A
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-2015-8138 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-2017-6458 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-2017-6462 2 Ntp, Redhat 2 Ntp, Enterprise Linux 2025-04-20 N/A
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-2016-7433 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-2015-7705 4 Citrix, Netapp, Ntp and 1 more 10 Xenserver, Clustered Data Ontap, Data Ontap and 7 more 2025-04-20 9.8 Critical
The rate limiting feature in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to have unspecified impact via a large number of crafted requests.
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-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-2015-7976 4 Novell, Ntp, Opensuse and 1 more 10 Suse Openstack Cloud, Ntp, Leap and 7 more 2025-04-20 N/A
The ntpq saveconfig command in NTP 4.1.2, 4.2.x before 4.2.8p6, 4.3, 4.3.25, 4.3.70, and 4.3.77 does not properly filter special characters, which allows attackers to cause unspecified impact via a crafted filename.
CVE-2016-2517 1 Ntp 1 Ntp 2025-04-20 N/A
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-2015-7692 5 Debian, Netapp, Ntp and 2 more 14 Debian Linux, Clustered Data Ontap, Data Ontap and 11 more 2025-04-20 7.5 High
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-2015-7703 5 Debian, Netapp, Ntp and 2 more 14 Debian Linux, Clustered Data Ontap, Data Ontap and 11 more 2025-04-20 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.
