2014-12-20 CVE-2014-9296 The receive function in ntp_proto.c in ntpd in NTP before 4.2.8 continues to execute after detecting a certain authentication error, which might allow remote attackers to trigger an unintended association change via crafted packets. Ntp N/A
2017-01-06 CVE-2016-1547 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. Ntp 5.3
2017-01-06 CVE-2016-1548 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. Ntp 7.2
2017-01-06 CVE-2016-1550 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. Ntp 5.3
2015-10-06 CVE-2014-9751 The read_network_packet function in ntp_io.c in ntpd in NTP 4.x before 4.2.8p1 on Linux and OS X does not properly determine whether a source IP address is an IPv6 loopback address, which makes it easier for remote attackers to spoof restricted packets, and read or write to the runtime state, by leveraging the ability to reach the ntpd machine's network interface with a packet from the ::1 address. Debian_linux, Ntp, Linux, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_workstation N/A
2018-03-08 CVE-2018-7183 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. Ubuntu_linux, Freebsd, Element_software, Ntp 9.8
2016-07-05 CVE-2016-4953 ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (ephemeral-association demobilization) by sending a spoofed crypto-NAK packet with incorrect authentication data at a certain time. Ntp, Leap, Opensuse, Solaris, Simatic_net_cp_443\-1_opc_ua_firmware, Tim_4r\-Ie_dnp3_firmware, Tim_4r\-Ie_firmware, Linux_enterprise_desktop, Linux_enterprise_server, Manager, Manager_proxy, Openstack_cloud 7.5
2017-08-07 CVE-2015-7853 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. Clustered_data_ontap, Data_ontap, Oncommand_balance, Oncommand_performance_manager, Oncommand_unified_manager, Ntp 9.8
2017-01-13 CVE-2016-7431 NTP before 4.2.8p9 allows remote attackers to bypass the origin timestamp protection mechanism via an origin timestamp of zero. NOTE: this vulnerability exists because of a CVE-2015-8138 regression. Ntp 5.3
2017-01-30 CVE-2016-2518 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. Debian_linux, Freebsd, Clustered_data_ontap, Data_ontap, Oncommand_balance, Oncommand_performance_manager, Oncommand_unified_manager_for_clustered_data_ontap, Ntp, Communications_user_data_repository, Linux, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_eus, Enterprise_linux_server_tus, Enterprise_linux_workstation, Simatic_net_cp_443\-1_opc_ua_firmware 5.3
