ntpq in NTP before 4.2.8p7 allows remote attackers to obtain origin timestamps and then impersonate peers via unspecified vectors. ntpq en NTP en versiones anteriores a 4.2.8p7 permite a atacantes remotos obtener timestamps de origen y luego suplantar a sus pares a través de vectores no especificados. • http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00060.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00038.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00048.html http://lists.opensuse.org/opensuse-updates/2016-05/msg00114.html http://support.ntp.org/bin/view/Main/NtpBug2946 http://tools&# • CWE-284: Improper Access Control •

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 •

https://notcve.org/view.php?id=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: 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 •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2016-1547 – ntp: crypto-NAK preemptable association denial of service
https://notcve.org/view.php?id=CVE-2016-1547
An off-path attacker can cause a preemptible client association to be demobilized in NTP 4.2.8p4 and earlier and NTPSec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 by sending a crypto NAK packet to a victim client with a spoofed source address of an existing associated peer. This is true even if authentication is enabled. Un atacante fuera de ruta puede provocar que una asociación de clientes preventiva sea desmovilizada en NTP 4.2.8p4 y versiones anteriores y NTPSec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 enviando un paquete NAK encriptado a un cliente víctima con una dirección fuente suplantada de un asociado existente. Esto es cierto incluso si la autenticación está habilitada. A denial of service flaw was found in the way NTP handled preemptable client associations. • http://rhn.redhat.com/errata/RHSA-2016-1552.html http://www.debian.org/security/2016/dsa-3629 http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.securityfocus.com/bid/88276 http://www.securitytracker.com/id/1035705 http://www.talosintelligence.com/reports/TALOS-2016-0081 https://access.redhat.com/errata/RHSA-2016:1141 https://cert-portal.siemens.com/productcert/pdf/ssa- • CWE-20: Improper Input Validation •
CVSS: 5.3EPSS: 0%CPEs: 125EXPL: 0CVE-2016-2518 – ntp: out-of-bounds references on crafted packet
https://notcve.org/view.php?id=CVE-2016-2518
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. An out-of-bounds access flaw was found in the way ntpd processed certain packets. An authenticated attacker could use a crafted packet to create a peer association with hmode of 7 and larger, which could potentially (although highly unlikely) cause ntpd to crash. • http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183647.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/184669.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00034.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00037.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2016& • CWE-125: Out-of-bounds Read •
