| CVE-2015-5300 | 7 Canonical, Debian, Fedoraproject and 4 more | 20 Ubuntu Linux, Debian Linux, Fedora and 17 more | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2016-1548 | 1 Ntp | 1 Ntp | 2025-04-20 | 6.4 MEDIUM | 7.2 HIGH |
| 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. | |||||

| 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-2016-7433 | 1 Ntp | 1 Ntp | 2025-04-20 | 5.0 MEDIUM | 5.3 MEDIUM |
| 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-2015-7849 | 2 Netapp, Ntp | 6 Clustered Data Ontap, Data Ontap, Oncommand Balance and 3 more | 2025-04-20 | 6.5 MEDIUM | 8.8 HIGH |
| Use-after-free vulnerability in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote authenticated users to possibly execute arbitrary code or cause a denial of service (crash) via crafted packets. | |||||
| CVE-2015-7852 | 5 Debian, Netapp, Ntp and 2 more | 14 Debian Linux, Clustered Data Ontap, Data Ontap and 11 more | 2025-04-20 | 4.3 MEDIUM | 5.9 MEDIUM |

| CVE-2015-7692 | 5 Debian, Netapp, Ntp and 2 more | 13 Debian Linux, Clustered Data Ontap, Data Ontap and 10 more | 2025-04-20 | 5.0 MEDIUM | 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-2017-6463 | 1 Ntp | 1 Ntp | 2025-04-20 | 4.0 MEDIUM | 6.5 MEDIUM |
| 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-2016-7427 | 1 Ntp | 1 Ntp | 2025-04-20 | 3.3 LOW | 4.3 MEDIUM |
| 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-2015-8158 | 1 Ntp | 1 Ntp | 2025-04-20 | 4.3 MEDIUM | 5.9 MEDIUM |
| The getresponse function in ntpq in NTP versions before 4.2.8p9 and 4.3.x before 4.3.90 allows remote attackers to cause a denial of service (infinite loop) via crafted packets with incorrect values. | |||||
| CVE-2016-9312 | 2 Microsoft, Ntp | 2 Windows, Ntp | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |

| 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. | |||||

| 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-2015-7975 | 1 Ntp | 1 Ntp | 2025-04-20 | 2.1 LOW | 6.2 MEDIUM |
