https://notcve.org/view.php?id=CVE-2017-6464
NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows remote attackers to cause a denial of service (ntpd crash) via a malformed mode configuration directive. NTP en versiones anteriores a 4.2.8p10 y 4.3.x en versiones anteriores a 4.3.94 permite a atacantes remotos provocar una denegación de servicio (caída ntpd) a través de una directiva de configuración de modo mal formado. A vulnerability was discovered in the NTP server's parsing of configuration directives. A remote, authenticated attacker could cause ntpd to crash by sending a crafted message. • http://support.ntp.org/bin/view/Main/NtpBug3389 http://support.ntp.org/bin/view/Main/SecurityNotice#March_2017_ntp_4_2_8p10_NTP_Secu http://www.securityfocus.com/bid/97050 http://www.securitytracker.com/id/1038123 https://access.redhat.com/errata/RHSA-2017:3071 https://access.redhat.com/errata/RHSA-2018:0855 https://security.FreeBSD.org/advisories/FreeBSD-SA-17:03.ntp.asc https://support.apple.com/HT208144 https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&a • CWE-20: Improper Input Validation •

The mx4200_send function in the legacy MX4200 refclock in NTP before 4.2.8p10 and 4.3.x before 4.3.94 does not properly handle the return value of the snprintf function, which allows local users to execute arbitrary code via unspecified vectors, which trigger an out-of-bounds memory write. La función mx4200_send en el refclock legado de MX4200 en NTP en versiones anteriores a 4.2.8p10 y 4.3.x en versiones anteriores a 4.3.94 no maneja correctamente el valor de retorno de la función snprintf, lo que permite a usuarios locales ejecutar código arbitrario a través de vectores no especificados, lo que desencadena una escritura de memoria fuera de límites. • http://support.ntp.org/bin/view/Main/NtpBug3378 http://support.ntp.org/bin/view/Main/SecurityNotice#March_2017_ntp_4_2_8p10_NTP_Secu http://www.securityfocus.com/bid/97058 http://www.securitytracker.com/id/1038123 http://www.securitytracker.com/id/1039427 https://support.apple.com/HT208144 https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbux03962en_us • CWE-787: Out-of-bounds Write •

CVSS: 4.3EPSS: 1%CPEs: 1EXPL: 0CVE-2016-7429 – ntp: Attack on interface selection
https://notcve.org/view.php?id=CVE-2016-7429
NTP before 4.2.8p9 changes the peer structure to the interface it receives the response from a source, which allows remote attackers to cause a denial of service (prevent communication with a source) by sending a response for a source to an interface the source does not use. NTP en versiones anteriores a 4.2.8p9 cambia la estructura de los pares a la interfaz que recibe la respuesta de una fuente, lo que permite a atacantes remotos provocar una denegación de servicio (prevenir la comunicación con una fuente) enviando una respuesta para una fuente a una interfaz que la fuente no utiliza. A flaw was found in the way ntpd running on a host with multiple network interfaces handled certain server responses. A remote attacker could use this flaw which would cause ntpd to not synchronize with the source. • http://nwtime.org/ntp428p9_release http://rhn.redhat.com/errata/RHSA-2017-0252.html http://support.ntp.org/bin/view/Main/NtpBug3072 http://support.ntp.org/bin/view/Main/SecurityNotice#Recent_Vulnerabilities http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/bid/94453 http://www.securitytracker.com/id/1037354 https://bto.bluecoat.com/security-advisory/sa139 https://h20566.www2.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr • CWE-18: DEPRECATED: Source Code •
