CVE-2016-9042 4 Freebsd, Hpe, Ntp and 1 more 5 Freebsd, Hpux-ntp, Ntp and 2 more 2024-09-17 5.9 Medium
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.
CVE-2016-4956 6 Novell, Ntp, Opensuse and 3 more 11 Suse Manager, Ntp, Leap and 8 more 2024-08-06 5.3 Medium
ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (interleaved-mode transition and time change) via a spoofed broadcast packet. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-1548.
CVE-2016-4953 5 Ntp, Opensuse, Oracle and 2 more 15 Ntp, Leap, Opensuse and 12 more 2024-08-06 7.5 High
ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (ephemeral-association demobilization) by sending a spoofed crypto-NAK packet with incorrect authentication data at a certain time.
CVE-2016-4955 6 Novell, Ntp, Opensuse and 3 more 11 Suse Manager, Ntp, Leap and 8 more 2024-08-06 5.9 Medium
ntpd in NTP 4.x before 4.2.8p8, when autokey is enabled, allows remote attackers to cause a denial of service (peer-variable clearing and association outage) by sending (1) a spoofed crypto-NAK packet or (2) a packet with an incorrect MAC value at a certain time.
CVE-2016-4954 5 Ntp, Opensuse, Oracle and 2 more 15 Ntp, Leap, Opensuse and 12 more 2024-08-06 7.5 High
The process_packet function in ntp_proto.c in ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (peer-variable modification) by sending spoofed packets from many source IP addresses in a certain scenario, as demonstrated by triggering an incorrect leap indication.
CVE-2016-2518 7 Debian, Freebsd, Netapp and 4 more 20 Debian Linux, Freebsd, Clustered Data Ontap and 17 more 2024-08-05 5.3 Medium
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.
CVE-2017-6458 4 Apple, Hpe, Ntp and 1 more 5 Mac Os X, Hpux-ntp, Ntp and 2 more 2024-08-05 8.8 High
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.
