Network Time Protocol Forced Interleaved Time Spoofing Vulnerability(CVE-2016-1548)

SUMMARY It is possible to change the time of an ntpd client or deny service to an ntpd client by forcing it to change from basic client/server mode to interleaved symmetric mode. An attacker can spoof a packet from a legitimate ntpd server with an origin timestamp that matches the peer-dst...

Network Time Protocol Crypto-NAK Preemptible Association Denial of Service Vulnerability(CVE-2016-1547)

SUMMARY An off-path attacker can cause a preemptible client association to be demobilized by sending a crypto NAK packet to a victim client with a spoofed source address of an existing associated peer. This is true even if authentication is enabled. Furthermore, if the attacker keeps sending cryp...

Network Time Protocol Broadcast Mode Poll Interval Enforcement Denial of Service Vulnerability(CVE-2016-7428)

Summary An exploitable denial of service vulnerability exists in the broadcast mode poll interval enforcement functionality of ntpd. To limit abuse, ntpd restricts the rate at which each broadcast association will process incoming packets. ntpd will reject broadcast mode packets that arrive befor...

Network Time Protocol Trap Crash Denial of Service Vulnerability(CVE-2016-9311)

Summary An exploitable denial of service vulnerability exists in the trap functionality of ntpd. If an ntpd instance is configured to send traps, a specially crafted network packet can be used to cause a null pointer dereference resulting in a denial of service. This vulnerability can be triggere...

Network Time Protocol Control Mode Unauthenticated Trap Information Disclosure and DDoS Amplification Vulnerability(CVE-2016-9310)

Summary An exploitable configuration modification vulnerability exists in the control mode mode 6 functionality of ntpd. A specially crafted control mode packet can set ntpd traps, providing information disclosure and DDoS amplification, and unset ntpd traps, preventing legitimate monitoring. A...

Network Time Protocol Broadcast Mode Replay Prevention Denial of Service Vulnerability(CVE-2016-7427)

Summary An exploitable denial of service vulnerability exists in the broadcast mode replay prevention functionality of ntpd. To prevent replay of broadcast mode packets, ntpd rejects broadcast mode packets with non-monotonically increasing transmit timestamps. Remote unauthenticated attackers can...
