2018-06-20 CVE-2018-12327 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. Ntp 9.8
2020-06-24 CVE-2020-15025 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. Ntp N/A
2020-06-04 CVE-2020-13817 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. Ntp N/A
2020-04-17 CVE-2020-11868 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. Debian_linux, All_flash_fabric\-Attached_storage_8300_firmware, All_flash_fabric\-Attached_storage_8700_firmware, All_flash_fabric\-Attached_storage_a400_firmware, Clustered_data_ontap, Data_ontap, Fabric\-Attached_storage_8300_firmware, Fabric\-Attached_storage_8700_firmware, Fabric\-Attached_storage_a400_firmware, Hci_management_node, Hci_storage_node_firmware, Solidfire, Vasa_provider_for_clustered_data_ontap, Virtual_storage_console, Ntp, Enterprise_linux N/A
2020-05-06 CVE-2018-8956 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. Ntp N/A
2019-05-15 CVE-2019-8936 NTP through 4.2.8p12 has a NULL Pointer Dereference. Fedora, Hpux\-Ntp, Clustered_data_ontap, Data_ontap, Ntp, Leap N/A
2018-03-06 CVE-2018-7185 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. Ubuntu_linux, Hpux\-Ntp, Hci, Solidfire, Ntp, Fujitsu_m10\-1_firmware, Fujitsu_m10\-4_firmware, Fujitsu_m10\-4s_firmware, Fujitsu_m12\-1_firmware, Fujitsu_m12\-2_firmware, Fujitsu_m12\-2s_firmware, Diskstation_manager, Router_manager, Skynas, Virtual_diskstation_manager, Vs960hd_firmware N/A
2018-03-06 CVE-2018-7170 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. Hpux\-Ntp, Hci, Solidfire, Ntp, Diskstation_manager, Router_manager, Skynas, Virtual_diskstation_manager, Vs960hd_firmware N/A
2017-01-13 CVE-2016-7434 The read_mru_list function in NTP before 4.2.8p9 allows remote attackers to cause a denial of service (crash) via a crafted mrulist query. Hpux\-Ntp, Ntp N/A
2017-01-13 CVE-2016-7426 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.
