DEBIAN-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...

DEBIAN-CVE-2018-7182

The ctlgetitem 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...

UBUNTU-CVE-2018-7170

ntpd in ntp 4.2.x before 4.2.8p7 and 4.3.x before 4.3.92 allows authenticated users that know the private symmetric key to create arbitrarily-many ephemeral associations in order to win the clock selection of ntpd and modify a victim's clock via a Sybil attack. This issue exists because of an...

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...
