The read_mru_list function in NTP before 4.2.8p9 allows remote attackers to cause a denial of service (crash) via a crafted mrulist query.
CVE-2016-7433 1 Ntp 1 Ntp 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
NTP before 4.2.8p9 does not properly perform the initial sync calculations, which allows remote attackers to unspecified impact via unknown vectors, related to a "root distance that did not include the peer dispersion."
CVE-2016-7431 1 Ntp 1 Ntp 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
NTP before 4.2.8p9 allows remote attackers to bypass the origin timestamp protection mechanism via an origin timestamp of zero. NOTE: this vulnerability exists because of a CVE-2015-8138 regression.
CVE-2016-7429 1 Ntp 1 Ntp 2024-11-21 4.3 MEDIUM 3.7 LOW
NTP before 4.2.8p9 changes the peer structure to the interface it receives the response from a source, which allows remote attackers to cause a denial of service (prevent communication with a source) by sending a response for a source to an interface the source does not use.
CVE-2016-7428 1 Ntp 1 Ntp 2024-11-21 3.3 LOW 4.3 MEDIUM
ntpd in NTP before 4.2.8p9 allows remote attackers to cause a denial of service (reject broadcast mode packets) via the poll interval in a broadcast packet.
CVE-2016-7427 1 Ntp 1 Ntp 2024-11-21 3.3 LOW 4.3 MEDIUM
The broadcast mode replay prevention functionality in ntpd in NTP before 4.2.8p9 allows remote attackers to cause a denial of service (reject broadcast mode packets) via a crafted broadcast mode packet.
CVE-2016-7426 4 Canonical, Hpe, Ntp and 1 more 9 Ubuntu Linux, Hpux-ntp, Ntp and 6 more 2024-11-21 4.3 MEDIUM 7.5 HIGH
NTP before 4.2.8p9 rate limits responses received from the configured sources when rate limiting for all associations is enabled, which allows remote attackers to cause a denial of service (prevent responses from the sources) by sending responses with a spoofed source address.
CVE-2016-4957 5 Novell, Ntp, Opensuse and 2 more 9 Suse Manager, Ntp, Leap and 6 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
ntpd in NTP before 4.2.8p8 allows remote attackers to cause a denial of service (daemon crash) via a crypto-NAK packet. NOTE: this vulnerability exists because of an incorrect fix for CVE-2016-1547.
CVE-2016-4956 6 Novell, Ntp, Opensuse and 3 more 11 Suse Manager, Ntp, Leap and 8 more 2024-11-21 5.0 MEDIUM 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-2016-4955 6 Novell, Ntp, Opensuse and 3 more 11 Suse Manager, Ntp, Leap and 8 more 2024-11-21 4.3 MEDIUM 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 2024-11-21 5.0 MEDIUM 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-2016-4953 5 Ntp, Opensuse, Oracle and 2 more 15 Ntp, Leap, Opensuse and 12 more 2024-11-21 5.0 MEDIUM 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-2016-2519 1 Ntp 1 Ntp 2024-11-21 4.9 MEDIUM 5.9 MEDIUM
ntpd in NTP before 4.2.8p7 and 4.3.x before 4.3.92 allows remote attackers to cause a denial of service (ntpd abort) by a large request data value, which triggers the ctl_getitem function to return a NULL value.
CVE-2016-2518 7 Debian, Freebsd, Netapp and 4 more 18 Debian Linux, Freebsd, Clustered Data Ontap and 15 more 2024-11-21 5.0 MEDIUM 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-2016-2517 1 Ntp 1 Ntp 2024-11-21 4.9 MEDIUM 5.3 MEDIUM
NTP before 4.2.8p7 and 4.3.x before 4.3.92 allows remote attackers to cause a denial of service (prevent subsequent authentication) by leveraging knowledge of the controlkey or requestkey and sending a crafted packet to ntpd, which changes the value of trustedkey, controlkey, or requestkey. NOTE: this vulnerability exists because of a CVE-2016-2516 regression.
CVE-2016-2516 1 Ntp 1 Ntp 2024-11-21 7.1 HIGH 5.3 MEDIUM
NTP before 4.2.8p7 and 4.3.x before 4.3.92, when mode7 is enabled, allows remote attackers to cause a denial of service (ntpd abort) by using the same IP address multiple times in an unconfig directive.
CVE-2016-1551 2 Ntp, Ntpsec 2 Ntp, Ntpsec 2024-11-21 2.6 LOW 3.7 LOW
ntpd in NTP 4.2.8p3 and NTPsec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 relies on the underlying operating system to protect it from requests that impersonate reference clocks. Because reference clocks are treated like other peers and stored in the same structure, any packet with a source ip address of a reference clock (127.127.1.1 for example) that reaches the receive() function will match that reference clock's peer record and will be treated as a trusted peer. Any system that lacks the typical martian packet filtering which would block these packets is in danger of having its time controlled by an attacker.
