| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2017-01-13 | CVE-2016-7429 | Source Code vulnerability in NTP 4.2.4/4.2.7/4.2.8 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. | 4.3 |
| 2017-01-13 | CVE-2016-7428 | Resource Exhaustion vulnerability in NTP 4.2.8 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. | 3.3 |
| 2017-01-13 | CVE-2016-7427 | Resource Exhaustion vulnerability in NTP 4.2.8 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. | 3.3 |
| 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-2016-1550 | Information Exposure vulnerability in NTP 4.2.8 An exploitable vulnerability exists in the message authentication functionality of libntp in ntp 4.2.8p4 and NTPSec a5fb34b9cc89b92a8fef2f459004865c93bb7f92. | 5.0 |
| 2017-01-06 | CVE-2016-1549 | Data Processing Errors vulnerability in NTP 4.2.8 A malicious authenticated peer can create arbitrarily-many ephemeral associations in order to win the clock selection algorithm in ntpd in NTP 4.2.8p4 and earlier and NTPsec 3e160db8dc248a0bcb053b56a80167dc742d2b74 and a5fb34b9cc89b92a8fef2f459004865c93bb7f92 and modify a victim's clock. | 4.0 |
| 2017-01-06 | CVE-2016-1548 | Data Processing Errors vulnerability in NTP 4.2.8 An attacker can spoof a packet from a legitimate ntpd server with an origin timestamp that matches the peer->dst timestamp recorded for that server. | 6.4 |
| 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 |
