DATE CVE VULNERABILITY TITLE RISK
2017-01-30 CVE-2016-2518 Out-of-bounds Read vulnerability in multiple products
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.

5.0
2017-01-30 CVE-2015-7977 NULL Pointer Dereference vulnerability in multiple products
ntpd in NTP before 4.2.8p6 and 4.3.x before 4.3.90 allows remote attackers to cause a denial of service (NULL pointer dereference) via a ntpdc reslist command.
4.3
2017-01-30 CVE-2015-7973 7PK - Security Features vulnerability in multiple products
NTP before 4.2.8p6 and 4.3.x before 4.3.90, when configured in broadcast mode, allows man-in-the-middle attackers to conduct replay attacks by sniffing the network.
5.8
2017-01-13 CVE-2016-7426 Resource Exhaustion vulnerability in NTP 4.2.5/4.2.6/4.2.7
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.
4.3
2016-07-05 CVE-2016-4957 NULL Pointer Dereference vulnerability in multiple products
ntpd in NTP before 4.2.8p8 allows remote attackers to cause a denial of service (daemon crash) via a crypto-NAK packet.

5.0
2016-07-05 CVE-2016-4956 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.

5.3
2016-07-05 CVE-2016-4955 Race Condition vulnerability in multiple products
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.

5.9
2016-07-05 CVE-2016-4954 Race Condition vulnerability in multiple products
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.

7.5
2016-07-05 CVE-2016-4953 Improper Authentication vulnerability in multiple products
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.

5.0
2016-01-26 CVE-2015-7974 Improper Authentication vulnerability in multiple products
NTP 4.x before 4.2.8p6 and 4.3.x before 4.3.90 do not verify peer associations of symmetric keys when authenticating packets, which might allow remote attackers to conduct impersonation attacks via an arbitrary trusted key, aka a "skeleton key."
