| 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-2015-5146 | 3 Debian, Fedoraproject, Ntp | 3 Debian Linux, Fedora, Ntp | 2025-04-20 | N/A |
| ntpd in ntp before 4.2.8p3 with remote configuration enabled allows remote authenticated users with knowledge of the configuration password and access to a computer entrusted to perform remote configuration to cause a denial of service (service crash) via a NULL byte in a crafted configuration directive packet. | ||||
| 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-2016-1551 | 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-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-2015-7855 | 4 Debian, Netapp, Ntp and 1 more | 11 Debian Linux, Clustered Data Ontap, Data Ontap and 8 more | 2025-04-20 | 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-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-2016-2519 | 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-2015-7850 | 3 Debian, Netapp, Ntp | 7 Debian Linux, Clustered Data Ontap, Data Ontap and 4 more | 2025-04-20 | 6.5 Medium |
| ntpd 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 (infinite loop or crash) by pointing the key file at the log file. | ||||
| CVE-2015-7691 | 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) via crafted packets containing particular autokey operations. NOTE: This vulnerability exists due to an incomplete fix for CVE-2014-9750. | ||||
| CVE-2017-6460 | 1 Ntp | 1 Ntp | 2025-04-20 | N/A |
| Stack-based buffer overflow in the reslist function in ntpq in NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows remote servers have unspecified impact via a long flagstr variable in a restriction list response. | ||||
| 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-2015-7692 | 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. | ||||
| CVE-2015-7979 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2025-04-20 | N/A |
| NTP before 4.2.8p6 and 4.3.x before 4.3.90 allows remote attackers to cause a denial of service (client-server association tear down) by sending broadcast packets with invalid authentication to a broadcast client. | ||||
| CVE-2016-1547 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2025-04-20 | N/A |
| An off-path attacker can cause a preemptible client association to be demobilized in NTP 4.2.8p4 and earlier and NTPSec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 by sending a crypto NAK packet to a victim client with a spoofed source address of an existing associated peer. This is true even if authentication is enabled. | ||||
| CVE-2016-1548 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2025-04-20 | N/A |
| An attacker can spoof a packet from a legitimate ntpd server with an origin timestamp that matches the peer->dst timestamp recorded for that server. After making this switch, the client in NTP 4.2.8p4 and earlier and NTPSec aa48d001683e5b791a743ec9c575aaf7d867a2b0c will reject all future legitimate server responses. It is possible to force the victim client to move time after the mode has been changed. ntpq gives no indication that the mode has been switched. | ||||
| 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-2017-6463 | 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 authenticated users to cause a denial of service (daemon crash) via an invalid setting in a :config directive, related to the unpeer option. | ||||
| CVE-2015-7973 | 5 Canonical, Freebsd, Netapp and 2 more | 9 Ubuntu Linux, Freebsd, Clustered Data Ontap and 6 more | 2025-04-20 | 6.5 Medium |
| NTP before 4.2.8p6 and 4.3.x before 4.3.90, when configured in broadcast mode, allows man-in-the-middle attackers to conduct replay attacks by sniffing the network. | ||||
