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 |
V4.0:(not available) 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.

V4.0:(not available) V3.1: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2019-8936 |

CVE-2016-9042 |
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.

V4.0:(not available) V3.1: 5.9 MEDIUM V2.0: 4.3 MEDIUM |
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 |
V4.0:(not available) 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 |
V4.0:(not available) 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 |
V4.0:(not available) 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 |

CVE-2017-6464 |
NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows remote attackers to cause a denial of service (ntpd crash) via a malformed mode configuration directive. Published: March 27, 2017; 1:59:00 PM -0400 |
