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-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 mos...

Network Time Protocol Origin Timestamp Check Denial of Service Vulnerability(CVE-2016-9042)

Summary 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...

CVE-2015-8138

CVE-2015-8138 relates to ntpd, where versions prior to 4.2.8p6 and 4.3.x prior to 4.3.90 allow a remote attacker to bypass origin timestamp validation by sending a packet with origin timestamp set to zero. Connected advisories confirm this is a real issue in ntpd and note it can enable spoofing o...
