| ntp_request.c in ntpd in NTP before 4.2.4p8, and 4.2.5, allows remote attackers to cause a denial of service (CPU and bandwidth consumption) by using MODE_PRIVATE to send a spoofed (1) request or (2) response packet that triggers a continuous exchange of MODE_PRIVATE error responses between two NTP daemons. | |||||

| CVE-2020-11868 | 5 Debian, Netapp, Ntp and 2 more | 24 Debian Linux, All Flash Fabric-attached Storage 8300, All Flash Fabric-attached Storage 8300 Firmware and 21 more | 2023-12-10 | 5.0 MEDIUM | 7.5 HIGH |
| ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address, because transmissions are rescheduled even when a packet lacks a valid origin timestamp. | |||||
| CVE-2020-15025 | 4 Netapp, Ntp, Opensuse and 1 more | 27 8300, 8300 Firmware, 8700 and 24 more | 2023-12-10 | 4.0 MEDIUM | 4.9 MEDIUM |
| ntpd in ntp 4.2.8 before 4.2.8p15 and 4.3.x before 4.3.101 allows remote attackers to cause a denial of service (memory consumption) by sending packets, because memory is not freed in situations where a CMAC key is used and associated with a CMAC algorithm in the ntp.keys file. | |||||
| CVE-2020-13817 | 4 Fujitsu, Netapp, Ntp and 1 more | 40 M10-1, M10-1 Firmware, M10-4 and 37 more | 2023-12-10 | 5.8 MEDIUM | 7.4 HIGH |
| ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows remote attackers to cause a denial of service (daemon exit or system time change) by predicting transmit timestamps for use in spoofed packets. The victim must be relying on unauthenticated IPv4 time sources. There must be an off-path attacker who can query time from the victim's ntpd instance. | |||||
| CVE-2018-8956 | 1 Ntp | 1 Ntp | 2023-12-10 | 5.0 MEDIUM | 5.3 MEDIUM |
| ntpd in ntp 4.2.8p10, 4.2.8p11, 4.2.8p12 and 4.2.8p13 allow remote attackers to prevent a broadcast client from synchronizing its clock with a broadcast NTP server via soofed mode 3 and mode 5 packets. The attacker must either be a part of the same broadcast network or control a slave in that broadcast network that can capture certain required packets on the attacker's behalf and send them to the attacker. | |||||
| CVE-2014-5209 | 2 F5, Ntp | 25 Big-ip Access Policy Manager, Big-ip Advanced Firewall Manager, Big-ip Analytics and 22 more | 2023-12-10 | 5.0 MEDIUM | 5.3 MEDIUM |
| An Information Disclosure vulnerability exists in NTP 4.2.7p25 private (mode 6/7) messages via a GET_RESTRICT control message, which could let a malicious user obtain sensitive information. | |||||
| CVE-2015-7851 | 1 Ntp | 1 Ntp | 2023-12-10 | 3.5 LOW | 6.5 MEDIUM |
| Directory traversal vulnerability in the save_config function in ntpd in ntp_control.c in NTP before 4.2.8p4, when used on systems that do not use '\' or '/' characters for directory separation such as OpenVMS, allows remote authenticated users to overwrite arbitrary files. | |||||
| CVE-2019-11331 | 1 Ntp | 1 Ntp | 2023-12-10 | 6.8 MEDIUM | 8.1 HIGH |
| Network Time Protocol (NTP), as specified in RFC 5905, uses port 123 even for modes where a fixed port number is not required, which makes it easier for remote attackers to conduct off-path attacks. | |||||
| CVE-2019-8936 | 5 Fedoraproject, Hpe, Netapp and 2 more | 6 Fedora, Hpux-ntp, Clustered Data Ontap and 3 more | 2023-12-10 | 5.0 MEDIUM | 7.5 HIGH |
| NTP through 4.2.8p12 has a NULL Pointer Dereference. | |||||
| CVE-2018-12327 | 1 Ntp | 1 Ntp | 2023-12-10 | 7.5 HIGH | 9.8 CRITICAL |
| Stack-based buffer overflow in ntpq and ntpdc of NTP version 4.2.8p11 allows an attacker to achieve code execution or escalate to higher privileges via a long string as the argument for an IPv4 or IPv6 command-line parameter. NOTE: It is unclear whether there are any common situations in which ntpq or ntpdc is used with a command line from an untrusted source. | |||||
| CVE-2018-7183 | 4 Canonical, Freebsd, Netapp and 1 more | 4 Ubuntu Linux, Freebsd, Element Software and 1 more | 2023-12-10 | 7.5 HIGH | 9.8 CRITICAL |
| Buffer overflow in the decodearr function in ntpq in ntp 4.2.8p6 through 4.2.8p10 allows remote attackers to execute arbitrary code by leveraging an ntpq query and sending a response with a crafted array. | |||||
| CVE-2018-7184 | 5 Canonical, Netapp, Ntp and 2 more | 10 Ubuntu Linux, Cloud Backup, Steelstore Cloud Integrated Storage and 7 more | 2023-12-10 | 5.0 MEDIUM | 7.5 HIGH |
| ntpd in ntp 4.2.8p4 before 4.2.8p11 drops bad packets before updating the "received" timestamp, which allows remote attackers to cause a denial of service (disruption) by sending a packet with a zero-origin timestamp causing the association to reset and setting the contents of the packet as the most recent timestamp. This issue is a result of an incomplete fix for CVE-2015-7704. | |||||
| CVE-2018-7170 | 4 Hpe, Netapp, Ntp and 1 more | 10 Hpux-ntp, Hci, Solidfire and 7 more | 2023-12-10 | 3.5 LOW | 5.3 MEDIUM |
| ntpd in ntp 4.2.x before 4.2.8p7 and 4.3.x before 4.3.92 allows authenticated users that know the private symmetric key to create arbitrarily-many ephemeral associations in order to win the clock selection of ntpd and modify a victim's clock via a Sybil attack. This issue exists because of an incomplete fix for CVE-2016-1549. | |||||
| CVE-2016-9042 | 4 Freebsd, Hpe, Ntp and 1 more | 5 Freebsd, Hpux-ntp, Ntp and 2 more | 2023-12-10 | 4.3 MEDIUM | 5.9 MEDIUM |
| An exploitable denial of service vulnerability exists in the origin timestamp check functionality of ntpd 4.2.8p9. A specially crafted unauthenticated network packet can be used to reset the expected origin timestamp for target peers. Legitimate replies from targeted peers will fail the origin timestamp check (TEST2) causing the reply to be dropped and creating a denial of service condition. | |||||
| CVE-2018-7185 | 6 Canonical, Hpe, Netapp and 3 more | 23 Ubuntu Linux, Hpux-ntp, Hci and 20 more | 2023-12-10 | 5.0 MEDIUM | 7.5 HIGH |
| The protocol engine in ntp 4.2.6 before 4.2.8p11 allows a remote attackers to cause a denial of service (disruption) by continually sending a packet with a zero-origin timestamp and source IP address of the "other side" of an interleaved association causing the victim ntpd to reset its association. | |||||
