08 Mar 2019 — NTP through 4.2.8p12 has a NULL Pointer Dereference. NTP hasta 4.2.8p12 tiene una desreferencia del puntero NULL. A crafted malicious authenticated mode 6 packet from a permitted network address can trigger a NULL pointer dereference. Note for this attack to work, the sending system must be on an address from which the target ntpd(8) accepts mode 6 packets, and must use a private key that is specifically listed as being used for mode 6 authorization. The ntpd daemon can crash due to the NULL pointer derefer... • https://github.com/snappyJack/CVE-2019-8936 • CWE-476: NULL Pointer Dereference •

01 Mar 2018 — ntpd in ntp 4.2.x before 4.2.8p7 and 4.3.x before 4.3.92 allows authenticated users that know the private symmetric key to create arbitrarily-many ephemeral associations in order to win the clock selection of ntpd and modify a victim's clock via a Sybil attack. This issue exists because of an incomplete fix for CVE-2016-1549. ntpd en ntp, en versiones 4.2.x anteriores a la 4.2.8p7 y versiones 4.3.x anteriores a la 4.3.92, permite que usuarios autenticados que conozcan la clave privada simétrica creen de for... • http://packetstormsecurity.com/files/146631/Slackware-Security-Advisory-ntp-Updates.html •

01 Mar 2018 — The protocol engine in ntp 4.2.6 before 4.2.8p11 allows a remote attackers to cause a denial of service (disruption) by continually sending a packet with a zero-origin timestamp and source IP address of the "other side" of an interleaved association causing the victim ntpd to reset its association.

12 Apr 2017 — An exploitable denial of service vulnerability exists in the origin timestamp check functionality of ntpd 4.2.8p9. A specially crafted unauthenticated network packet can be used to reset the expected origin timestamp for target peers. Legitimate replies from targeted peers will fail the origin timestamp check (TEST2) causing the reply to be dropped and creating a denial of service condition. Existe una vulnerabilidad explotable de denegación de servicio (DoS) en la funcionalidad de comprobación de marca de ... • http://packetstormsecurity.com/files/142101/FreeBSD-Security-Advisory-FreeBSD-SA-17-03.ntp.html • CWE-20: Improper Input Validation •

27 Mar 2017 — Multiple buffer overflows in the ctl_put* functions in NTP before 4.2.8p10 and 4.3.x before 4.3.94 allow remote authenticated users to have unspecified impact via a long variable. Múltiples desbordamientos de búfer en las funciones ctl_put * en NTP en versiones anteriores a 4.2.8p10 y 4.3.x en versiones anteriores a 4.3.94 permiten a usuarios remotos autenticados tener un impacto no especificado a través de una variable larga.
