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-2015-8140 1 Ntp 1 Ntp 2025-04-20 N/A
The ntpq protocol in NTP before 4.2.8p7 allows remote attackers to conduct replay attacks by sniffing the network.
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-2016-1547 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-2015-7852 5 Debian, Netapp, Ntp and 2 more 15 Debian Linux, Clustered Data Ontap, Data Ontap and 12 more 2025-04-20 5.9 Medium
ntpq 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 mode 6 response packets.
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-2016-2517 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-2017-6460 1 Ntp 1 Ntp 2025-04-20 N/A
Stack-based buffer overflow in the reslist function in ntpq in NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows remote servers have unspecified impact via a long flagstr variable in a restriction list response.
CVE-2017-6451 1 Ntp 1 Ntp 2025-04-20 N/A
The mx4200_send function in the legacy MX4200 refclock in NTP before 4.2.8p10 and 4.3.x before 4.3.94 does not properly handle the return value of the snprintf function, which allows local users to execute arbitrary code via unspecified vectors, which trigger an out-of-bounds memory write.
CVE-2015-7850 3 Debian, Netapp, Ntp 7 Debian Linux, Clustered Data Ontap, Data Ontap and 4 more 2025-04-20 6.5 Medium
ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote authenticated users to cause a denial of service (infinite loop or crash) by pointing the key file at the log file.
CVE-2017-6452 1 Ntp 1 Ntp 2025-04-20 N/A
Stack-based buffer overflow in the Windows installer for NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows local users to have unspecified impact via an application path on the command line.
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-2016-7427 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-2016-7428 1 Ntp 1 Ntp 2025-04-20 N/A
ntpd in NTP before 4.2.8p9 allows remote attackers to cause a denial of service (reject broadcast mode packets) via the poll interval in a broadcast packet.
CVE-2016-7431 1 Ntp 1 Ntp 2025-04-20 N/A
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.
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-2017-6459 1 Ntp 1 Ntp 2025-04-20 N/A
The Windows installer for NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows local users to have unspecified impact via vectors related to an argument with multiple null bytes.
