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 o (2) un paquete con un valor MAC incorrecto en un momento determinado. • http://bugs.ntp.org/3043 http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00040.html http://lists.opensuse.org/ • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

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. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2016-1548. • http://bugs.ntp.org/3042 http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00040.html http://lists.opensuse.org/ •

NTP before 4.2.8p7 and 4.3.x before 4.3.92, when mode7 is enabled, allows remote attackers to cause a denial of service (ntpd abort) by using the same IP address multiple times in an unconfig directive. NTP en versiones anteriores a 4.2.8p7 y 4.3.x en versiones anteriores a 4.3.92, cuando mode7 está habilitado, permite a atacantes remotos provocar una denegación de servicio (anular ntpd) usando la misma dirección IP varias veces en una directiva unconfig. • http://support.ntp.org/bin/view/Main/NtpBug3011 http://www.debian.org/security/2016/dsa-3629 http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.securityfocus.com/bid/88180 http://www.securitytracker.com/id/1035705 https://security.FreeBSD.org/advisories/FreeBSD-SA-16:16.ntp.asc https://security.gentoo.org/glsa/201607-15 https://security.netapp.com/advisory/ntap-20171004-0002 https://www.kb.cert.org/vuls/id/718152 • CWE-20: Improper Input Validation •

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: this vulnerability exists because of a CVE-2016-2516 regression. NTP en versiones anteriores a 4.2.8p7 y 4.3.x en versiones anteriores a 4.3.92 permite a los atacantes remotos provocar una denegación de servicio (evitar la posterior autenticación) aprovechando el conocimiento de la clave de control o requestkey y enviando un paquete creado a ntpd, que cambia el valor de trustedkey, Controlkey o requestkey. NOTA: esta vulnerabilidad existe debido a una regresión de la CVE-2016-2516. • http://support.ntp.org/bin/view/Main/NtpBug3010 http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.securityfocus.com/bid/88189 http://www.securitytracker.com/id/1035705 https://security.FreeBSD.org/advisories/FreeBSD-SA-16:16.ntp.asc https://security.gentoo.org/glsa/201607-15 https://security.netapp.com/advisory/ntap-20171004-0002 https://www.kb.cert.org/vuls/id/718152 • CWE-20: Improper Input Validation •

ntpd in NTP before 4.2.8p7 and 4.3.x before 4.3.92 allows remote attackers to cause a denial of service (ntpd abort) by a large request data value, which triggers the ctl_getitem function to return a NULL value. Ntpd en NTP en versiones anteriores a 4.2.8p7 y 4.3.x en versiones anteriores a 4.3.92 permite a los atacantes remotos causar una denegación de servicio (ntpd abort) por un gran petición de valores de datos, lo que activa la función ctl_getitem para devolver un valor NULL. • http://support.ntp.org/bin/view/Main/NtpBug3008 http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.securityfocus.com/bid/88204 http://www.securitytracker.com/id/1035705 https://security.FreeBSD.org/advisories/FreeBSD-SA-16:16.ntp.asc https://security.gentoo.org/glsa/201607-15 https://security.netapp.com/advisory/ntap-20171004-0002 https://www.kb.cert.org/vuls/id/718152 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
