| CVE-2016-1551 | 2 Ntp, Ntpsec | 2 Ntp, Ntpsec | 2017-11-21 | 2.6 LOW | 3.7 LOW |
| 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 | 2017-11-21 | 7.1 HIGH | 5.3 MEDIUM |

| 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-2016-2519 | 1 Ntp | 1 Ntp | 2017-11-21 | 4.9 MEDIUM | 5.9 MEDIUM |
| 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-2015-7848 | 1 Ntp | 1 Ntp-dev | 2017-11-10 | 5.0 MEDIUM | 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. | |||||

| NTP before 4.2.8p10 and 4.3.x before 4.3.94, when using PPSAPI, allows local users to gain privileges via a DLL in the PPSAPI_DLLS environment variable. | |||||
| CVE-2017-6452 | 1 Ntp | 1 Ntp | 2017-10-24 | 4.6 MEDIUM | 7.8 HIGH |
| Stack-based buffer overflow in 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 an application path on the command line. | |||||
| CVE-2017-6451 | 1 Ntp | 1 Ntp | 2017-10-24 | 4.6 MEDIUM | 7.8 HIGH |
| 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. | |||||
