| 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-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-2015-8140 | 1 Ntp | 1 Ntp | 2025-04-20 | N/A |
| The ntpq protocol in NTP before 4.2.8p7 allows remote attackers to conduct replay attacks by sniffing the network. | ||||
| 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-2016-1551 | 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-2016-2516 | 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-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-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-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-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-2016-2519 | 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-2015-7853 | 2 Netapp, Ntp | 6 Clustered Data Ontap, Data Ontap, Oncommand Balance and 3 more | 2025-04-20 | 9.8 Critical |
| The datalen parameter in the refclock driver in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to execute arbitrary code or cause a denial of service (crash) via a negative input value. | ||||
| CVE-2016-7426 | 4 Canonical, Hpe, Ntp and 1 more | 10 Ubuntu Linux, Hpux-ntp, Ntp and 7 more | 2025-04-20 | 7.5 High |
| NTP before 4.2.8p9 rate limits responses received from the configured sources when rate limiting for all associations is enabled, which allows remote attackers to cause a denial of service (prevent responses from the sources) by sending responses with a spoofed source address. | ||||
| 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-2016-7428 | 1 Ntp | 1 Ntp | 2025-04-20 | N/A |
| ntpd in NTP before 4.2.8p9 allows remote attackers to cause a denial of service (reject broadcast mode packets) via the poll interval in a broadcast packet. | ||||
| CVE-2016-2518 | 7 Debian, Freebsd, Netapp and 4 more | 20 Debian Linux, Freebsd, Clustered Data Ontap and 17 more | 2025-04-20 | 5.3 Medium |
| The MATCH_ASSOC function in NTP before version 4.2.8p9 and 4.3.x before 4.3.92 allows remote attackers to cause an out-of-bounds reference via an addpeer request with a large hmode value. | ||||
| CVE-2015-3405 | 7 Debian, Fedoraproject, Ntp and 4 more | 14 Debian Linux, Fedora, Ntp and 11 more | 2025-04-20 | N/A |
| ntp-keygen in ntp 4.2.8px before 4.2.8p2-RC2 and 4.3.x before 4.3.12 does not generate MD5 keys with sufficient entropy on big endian machines when the lowest order byte of the temp variable is between 0x20 and 0x7f and not #, which might allow remote attackers to obtain the value of generated MD5 keys via a brute force attack with the 93 possible keys. | ||||
