CVE-2018-7170
https://notcve.org/view.php?id=CVE-2018-7170
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 forma arbitraria muchas asociaciones efímeras para ganar la selección de reloj de ntpd y modifiquen el reloj de una víctima mediante un ataque Sybil. Este problema existe debido a una solución incompleta para CVE-2016-1549. • http://packetstormsecurity.com/files/146631/Slackware-Security-Advisory-ntp-Updates.html http://support.ntp.org/bin/view/Main/NtpBug3415 http://www.securityfocus.com/archive/1/541824/100/0/threaded http://www.securityfocus.com/bid/103194 https://bugzilla.redhat.com/show_bug.cgi?id=1550214 https://security.FreeBSD.org/advisories/FreeBSD-SA-18:02.ntp.asc https://security.gentoo.org/glsa/201805-12 https://security.netapp.com/advisory/ntap-20180626-0001 https://support.hpe.com/hpsc/doc •
CVE-2016-9042
https://notcve.org/view.php?id=CVE-2016-9042
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 tiempo de origen de ntpd 4.2.8p9. Se puede emplear un paquete de red no autenticado especialmente manipulado para reiniciar la marca de tiempo de origen esperada para los peers objetivo. • http://packetstormsecurity.com/files/142101/FreeBSD-Security-Advisory-FreeBSD-SA-17-03.ntp.html http://packetstormsecurity.com/files/142284/Slackware-Security-Advisory-ntp-Updates.html http://seclists.org/fulldisclosure/2017/Nov/7 http://seclists.org/fulldisclosure/2017/Sep/62 http://www.securityfocus.com/archive/1/540403/100/0/threaded http://www.securityfocus.com/archive/1/archive/1/540403/100/0/threaded http://www.securityfocus.com/archive/1/archive/1/540464/100/0/threaded http:// • CWE-20: Improper Input Validation •

CVE-2017-6462 – ntp: Buffer Overflow in DPTS Clock
https://notcve.org/view.php?id=CVE-2017-6462
Buffer overflow in the legacy Datum Programmable Time Server (DPTS) refclock driver in NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows local users to have unspecified impact via a crafted /dev/datum device. Desbordamiento de búfer en el controlador refclock legado Datum Programmable Time Server (DPTS) en NTP en versiones anteriores a 4.2.8p10 y 4.3.x en versiones anteriores a 4.3.94 permite a usuarios locales tener un impacto no especificado a través de un dispositivo /dev/datum manipulado. A vulnerability was found in NTP, in the parsing of packets from the /dev/datum device.
