| 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. | 3.7 |
| 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. | 4.3 |
| 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. | 4.3 |
| 2017-01-13 | CVE-2016-7426 | Resource Exhaustion vulnerability in multiple products 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. | 7.5 |
| 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. | 5.3 |
| 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. | 6.5 |
| 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. | 7.2 |
| 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. | 5.3 |
| 2017-01-06 | CVE-2015-7848 | Integer Overflow or Wraparound vulnerability in NTP Ntp-Dev 4.3.70 An integer overflow can occur in NTP-dev.4.3.70 leading to an out-of-bounds memory copy operation when processing a specially crafted private mode packet. | 7.5 |
| 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. | 7.5 |
