| 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-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-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-2016-7431 | 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-2016-7433 | 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-2015-5194 | 6 Canonical, Debian, Fedoraproject and 3 more | 14 Ubuntu Linux, Debian Linux, Fedora and 11 more | 2025-04-20 | N/A |
| The log_config_command function in ntp_parser.y in ntpd in NTP before 4.2.7p42 allows remote attackers to cause a denial of service (ntpd crash) via crafted logconfig commands. | ||||
| 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-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-2016-1549 | 1 Ntp | 1 Ntp | 2025-04-20 | N/A |
| A malicious authenticated peer can create arbitrarily-many ephemeral associations in order to win the clock selection algorithm in ntpd in NTP 4.2.8p4 and earlier and NTPsec 3e160db8dc248a0bcb053b56a80167dc742d2b74 and a5fb34b9cc89b92a8fef2f459004865c93bb7f92 and modify a victim's clock. | ||||
| CVE-2015-7704 | 6 Citrix, Debian, Mcafee and 3 more | 16 Xenserver, Debian Linux, Enterprise Security Manager and 13 more | 2025-04-20 | 7.5 High |
| The ntpd client in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service via a number of crafted "KOD" messages. | ||||
| 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-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. | ||||
| 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-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-2016-9312 | 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. | ||||
| CVE-2015-7977 | 9 Canonical, Debian, Fedoraproject and 6 more | 13 Ubuntu Linux, Debian Linux, Fedora and 10 more | 2025-04-20 | 5.9 Medium |
| ntpd in NTP before 4.2.8p6 and 4.3.x before 4.3.90 allows remote attackers to cause a denial of service (NULL pointer dereference) via a ntpdc reslist command. | ||||
| 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-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. | ||||
| CVE-2015-5219 | 10 Canonical, Debian, Fedoraproject and 7 more | 21 Ubuntu Linux, Debian Linux, Fedora and 18 more | 2025-04-20 | 7.5 High |
