https://notcve.org/view.php?id=CVE-2015-5195
ntp_openssl.m4 in ntpd in NTP before 4.2.7p112 allows remote attackers to cause a denial of service (segmentation fault) via a crafted statistics or filegen configuration command that is not enabled during compilation. ntp_openssl.m4 en ntpd en NTP anterior a 4.2.7p112, permite a los atacantes remotos causar una denegación de servicio (fallo de segmentación) por medio de un comando de configuración statistics o filegen creadas que no está habilitado durante la compilación. It was found that ntpd would exit with a segmentation fault when a statistics type that was not enabled during compilation (e.g. timingstats) was referenced by the statistics or filegen configuration command. • https://github.com/theglife214/CVE-2015-5195 http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170926.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169167.html http://lists.fedoraproject.org/pipermail/package-announce/2015-September/166992.html http://rhn.redhat.com/errata/RHSA-2016-0780.html http://rhn.redhat.com/errata/RHSA-2016-2583.html http://www.debian.org/security/2015/dsa-3388 http://www.openwall.com/lists/oss-security/2015/08/25& • CWE-20: Improper Input Validation CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2015-5194
The log_config_command function in ntp_parser.y in ntpd in NTP before 4.2.7p42 allows remote attackers to cause a denial of service (ntpd crash) via crafted logconfig commands. La función log_config_command en el archivo ntp_parser.y en ntpd en NTP anterior a versión 4.2.7p42, permite a los atacantes remotos causar una denegación de servicio (bloqueo de ntpd) por medio de comandos logconfig creados. It was found that ntpd could crash due to an uninitialized variable when processing malformed logconfig configuration commands. • http://bk1.ntp.org/ntp-dev/?PAGE=patch&REV=4c4fc141LwvcoGp-lLGhkAFp3ZvtrA http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170926.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169167.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00048.html http://lists.opensuse.org/opensuse-security-announce/2016-07/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00042.html http://rhn.redhat.com/errata/RHSA-2016-0780. • CWE-20: Improper Input Validation CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2015-5219
The ULOGTOD function in ntp.d in SNTP before 4.2.7p366 does not properly perform type conversions from a precision value to a double, which allows remote attackers to cause a denial of service (infinite loop) via a crafted NTP packet. La función ULOGTOD en el archivo ntp.d en SNTP en versiones anteriores a la 4.2.7p366 no realiza apropiadamente las conversiones de tipo de un valor de precisión a uno doble, lo que permite a los atacantes remotos causar una denegación de servicio (bucle infinito) por medio de un paquete NTP creado. It was discovered that the sntp utility could become unresponsive due to being caught in an infinite loop when processing a crafted NTP packet. • http://aix.software.ibm.com/aix/efixes/security/ntp_advisory4.asc http://bk1.ntp.org/ntp-dev/?PAGE=patch&REV=51786731Gr4-NOrTBC_a_uXO4wuGhg http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170926.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169167.html http://lists.fedoraproject.org/pipermail/package-announce/2015-September/166992.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00048.html http://lists.opensuse.org/opensuse-updates&#x • CWE-704: Incorrect Type Conversion or Cast CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVSS: 7.5EPSS: 5%CPEs: 38EXPL: 0CVE-2015-5300 – ntp: MITM attacker can force ntpd to make a step larger than the panic threshold
https://notcve.org/view.php?id=CVE-2015-5300
The panic_gate check in NTP before 4.2.8p5 is only re-enabled after the first change to the system clock that was greater than 128 milliseconds by default, which allows remote attackers to set NTP to an arbitrary time when started with the -g option, or to alter the time by up to 900 seconds otherwise by responding to an unspecified number of requests from trusted sources, and leveraging a resulting denial of service (abort and restart). La comprobación panic_gate en NTP anterior a versión 4.2.8p5 es solo habilitada nuevamente después del primer cambio al reloj del sistema que fue mayor que 128 milisegundos por defecto, permitiendo a los atacantes remotos fijar el NTP a un tiempo arbitrario cuando arranca con la opción -g, o alterar el tiempo hasta 900 segundos, de lo contrario por respuesta a un número no especificado de peticiones de fuentes de confianza y aprovechando una denegación de servicio resultante (anular y reiniciar). It was found that ntpd did not correctly implement the threshold limitation for the '-g' option, which is used to set the time without any restrictions. A man-in-the-middle attacker able to intercept NTP traffic between a connecting client and an NTP server could use this flaw to force that client to make multiple steps larger than the panic threshold, effectively changing the time to an arbitrary value at any time. • http://aix.software.ibm.com/aix/efixes/security/ntp_advisory5.asc http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170684.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170926.html http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177507.html 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-announc • CWE-20: Improper Input Validation CWE-361: 7PK - Time and State •

https://notcve.org/view.php?id=CVE-2015-7852
ntpq in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service (crash) via crafted mode 6 response packets. ntpd en NTP 4.2.x en versiones anteriores a 4.2.8p4, y 4.3.x en versiones anteriores a 4.3.77 permite que atacantes remotos provoquen una denegación de servicio empleando paquetes de respuesta en modo 6 manipulados. An off-by-one flaw, leading to a buffer overflow, was found in cookedprint functionality of ntpq. A specially crafted NTP packet could potentially cause ntpq to crash. • http://rhn.redhat.com/errata/RHSA-2016-0780.html http://rhn.redhat.com/errata/RHSA-2016-2583.html http://support.ntp.org/bin/view/Main/NtpBug2919 http://www.debian.org/security/2015/dsa-3388 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.securityfocus.com/bid/77288 http://www.securitytracker.com/id/1033951 https://security.gentoo.org/glsa/201607-15 https://security.netapp.com/advisory/ntap-20171004-0001 https://access.redhat.com& • CWE-20: Improper Input Validation CWE-193: Off-by-one Error •
