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-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-2015-7691 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-2015-7701 5 Debian, Netapp, Ntp and 2 more 14 Debian Linux, Clustered Data Ontap, Data Ontap and 11 more 2025-04-20 7.5 High
Memory leak in the CRYPTO_ASSOC 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 (memory consumption).
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-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-2016-2519 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-2015-3405 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.
CVE-2015-5300 7 Canonical, Debian, Fedoraproject and 4 more 21 Ubuntu Linux, Debian Linux, Fedora and 18 more 2025-04-20 N/A
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).
