CVE-2017-6464 – ntp: Denial of Service via Malformed Config
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.

CVE-2017-6451
https://notcve.org/view.php?id=CVE-2017-6451
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 •
