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 •

06 Jun 2016 — The process_packet function in ntp_proto.c in ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (peer-variable modification) by sending spoofed packets from many source IP addresses in a certain scenario, as demonstrated by triggering an incorrect leap indication.

06 Jun 2016 — ntpd in NTP 4.x before 4.2.8p8, when autokey is enabled, allows remote attackers to cause a denial of service (peer-variable clearing and association outage) by sending (1) a spoofed crypto-NAK packet or (2) a packet with an incorrect MAC value at a certain time. ntpd en NTP 4.x en versiones anteriores a 4.2.8p8, cuando está habilitada la autoclave, permite a atacantes remotos provocar una denegación de servicio (limpiando el par variable y corte de asociación) enviando (1) un paquete crypto-NAK manipulado ... • http://bugs.ntp.org/3043 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

06 Jun 2016 — ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (interleaved-mode transition and time change) via a spoofed broadcast packet. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-1548. ntpd en NTP 4.x en versiones anteriores a 4.2.8p8 permite a atacantes remotos provocar una denegación de servicio (transición de modo intercalado y cambio de hora) a través de un paquete de difusión manipulado.

02 May 2016 — The MATCH_ASSOC function in NTP before version 4.2.8p9 and 4.3.x before 4.3.92 allows remote attackers to cause an out-of-bounds reference via an addpeer request with a large hmode value. La función MATCH_ASSOC en NTP en versiones anteriores 4.2.8p9 y 4.3.x en versiones anteriores a 4.3.92 permite a atacantes remotos provocar una referencia fuera de los límites a través de una solicitud addpeer con un valor hmode grande.
