CVE-2015-7975

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...

CVE-2015-7976

The ntpq saveconfig command in NTP 4.1.2, 4.2.x before 4.2.8p6, 4.3, 4.3.25, 4.3.70, and 4.3.77 does not properly filter special characters, which allows attackers to cause unspecified impact via a crafted filename...

CVE-2015-7978

NTP before 4.2.8p6 and 4.3.0 before 4.3.90 allows a remote attackers to cause a denial of service stack exhaustion via an ntpdc relist command, which triggers recursive traversal of the restriction list...

CVE-2016-2517

NTP before 4.2.8p7 and 4.3.x before 4.3.92 allows remote attackers to cause a denial of service prevent subsequent authentication by leveraging knowledge of the controlkey or requestkey and sending a crafted packet to ntpd, which changes the value of trustedkey, controlkey, or requestkey. NOTE:...

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-2016-2517

CVE-2016-2517 refers to ntpd remote configuration vulnerabilities where, if ntpd is configured to allow remote configuration, an attacker who knows the controlkey or requestkey (when mode7 is enabled) can send crafted packets to ntpd and alter the values of trustedkey, controlkey, or requestkey, ...

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...
