CVE-2015-7979

NTP before 4.2.8p6 and 4.3.x before 4.3.90 allows remote attackers to cause a denial of service client-server association tear down by sending broadcast packets with invalid authentication to a broadcast client...

CVE-2016-2516

CVE-2016-2516 affects ntp before 4.2.8p7 and 4.3.x before 4.3.92. When mode7 is enabled, ntpd can abort or crash due to duplicate IPs on unconfig directives, enabling remote denial of service. Publicly documented fixes exist: Debian security advisories note patches in ntp packages (e.g., Jessie u...

CVE-2016-1551

ntpd in NTP 4.2.8p3 and NTPsec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 relies on the underlying operating system to protect it from requests that impersonate reference clocks. Because reference clocks are treated like other peers and stored in the same structure, any packet with a source ip...

CVE-2016-1551

CVE-2016-1551 affects ntpd (NTP 4.2.8p3 and NTPsec a5fb34b9…). The flaw arises because reference clocks are stored with regular peers; if a system lacks martian-filtering, a packet with a reference-clock source (e.g., 127.127.1.1) reaching receive() can be treated as a trusted peer, enabling an a...

DEBIAN-CVE-2016-7431

NTP before 4.2.8p9 allows remote attackers to bypass the origin timestamp protection mechanism via an origin timestamp of zero. NOTE: this vulnerability exists because of a CVE-2015-8138 regression...

CVE-2016-9310

The control mode mode 6 functionality in ntpd in NTP before 4.2.8p9 allows remote attackers to set or unset traps via a crafted control mode packet...

CVE-2016-7426

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...

CVE-2016-9311

ntpd in NTP before 4.2.8p9, when the trap service is enabled, allows remote attackers to cause a denial of service NULL pointer dereference and crash via a crafted packet...

CVE-2016-7426

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...

CVE-2016-7429

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...

CVE-2016-7433

NTP before 4.2.8p9 does not properly perform the initial sync calculations, which allows remote attackers to unspecified impact via unknown vectors, related to a "root distance that did not include the peer dispersion."...

CVE-2016-7434

The readmrulist function in NTP before 4.2.8p9 allows remote attackers to cause a denial of service crash via a crafted mrulist query...

CVE-2016-1549

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...

CVE-2016-1547

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. This is true even if...

CVE-2016-1547

CVE-2016-1547 describes a denial-of-service vulnerability in ntpd where handling of crypto NAK packets can demobilize a preemptable client association. An off-path attacker can spoof a peer’s source and force the victim to drop synchronization, even with authentication enabled. The issue affects ...
