| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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. | 7.5 |
| 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." | 7.7 |
