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. Published: June 04, 2020; 9:15:11 AM -0400 |
V3.1: 7.4 HIGH V2.0: 5.8 MEDIUM |
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.

V3.1: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2019-8936 |

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. Published: March 08, 2018; 3:29:00 PM -0500 |
V3.0: 9.8 CRITICAL V2.0: 7.5 HIGH |
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. Published: March 06, 2018; 3:29:01 PM -0500 |
V3.1: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2018-7184 |
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. Published: March 06, 2018; 3:29:01 PM -0500 |
V3.0: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2018-7182 |
The ctl_getitem method in ntpd in ntp-4.2.8p6 before 4.2.8p11 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted mode 6 packet with a ntpd instance from 4.2.8p6 through 4.2.8p10. Published: March 06, 2018; 3:29:01 PM -0500 |
V3.0: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2017-6458 |
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. Published: March 27, 2017; 1:59:00 PM -0400 |
V3.1: 8.8 HIGH V2.0: 6.5 MEDIUM |
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. Published: January 30, 2017; 4:59:01 PM -0500 |
V3.1: 5.3 MEDIUM V2.0: 5.0 MEDIUM |
CVE-2016-9312 |

V3.0: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2016-9311 |
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. Published: January 13, 2017; 11:59:00 AM -0500 |
V3.0: 5.9 MEDIUM V2.0: 7.1 HIGH |
CVE-2016-9310 |
