| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2017-01-30 | CVE-2015-7975 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in NTP The nextvar function in NTP before 4.2.8p6 and 4.3.x before 4.3.90 does not properly validate the length of its input, which allows an attacker to cause a denial of service (application crash). | 2.1 |
| 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 |
| 2017-01-06 | CVE-2016-1547 | Improper Input Validation vulnerability in NTP An off-path attacker can cause a preemptible client association to be demobilized in NTP 4.2.8p4 and earlier and NTPSec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 by sending a crypto NAK packet to a victim client with a spoofed source address of an existing associated peer. | 5.0 |
| 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." | 4.0 |
