| 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-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-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-2016-9311 | 2 Ntp, Redhat | 2 Ntp, Enterprise Linux | 2025-04-20 | N/A |
| ntpd in NTP before 4.2.8p9, when the trap service is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted packet. | ||||
| CVE-2016-9310 | 2 Ntp, Redhat | 2 Ntp, Enterprise Linux | 2025-04-20 | N/A |
| The control mode (mode 6) functionality in ntpd in NTP before 4.2.8p9 allows remote attackers to set or unset traps via a crafted control mode packet. | ||||
| 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-2016-7427 | 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-2016-7426 | 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-2016-1549 | 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-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-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-2016-1551 | 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-2015-7979 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2025-04-20 | N/A |
| 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-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-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-2015-8158 | 2 Ntp, Redhat | 2 Ntp, Enterprise Linux | 2025-04-20 | N/A |
| 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-2016-1548 | 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-2016-1550 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2025-04-20 | N/A |
| An exploitable vulnerability exists in the message authentication functionality of libntp in ntp 4.2.8p4 and NTPSec a5fb34b9cc89b92a8fef2f459004865c93bb7f92. An attacker can send a series of crafted messages to attempt to recover the message digest key. | ||||
| 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-2015-5219 | 10 Canonical, Debian, Fedoraproject and 7 more | 21 Ubuntu Linux, Debian Linux, Fedora and 18 more | 2025-04-20 | 7.5 High |
| The ULOGTOD function in ntp.d in SNTP before 4.2.7p366 does not properly perform type conversions from a precision value to a double, which allows remote attackers to cause a denial of service (infinite loop) via a crafted NTP packet. | ||||
