https://notcve.org/view.php?id=CVE-2017-6463
NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows remote authenticated users to cause a denial of service (daemon crash) via an invalid setting in a :config directive, related to the unpeer option. NTP en versiones anteriores a 4.2.8p10 y 4.3.x en versiones anteriores a 4.3.94 permite a usuarios remotos autenticados provocar una denegación de servicio (caída del demonio) a través de una configuración no válida en al directiva :config, relacionado con la opción unpeer. 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/NtpBug3387 http://support.ntp.org/bin/view/Main/SecurityNotice#March_2017_ntp_4_2_8p10_NTP_Secu http://www.securityfocus.com/bid/97049 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 CWE-476: NULL Pointer Dereference •

CVSS: 7.5EPSS: 5%CPEs: 92EXPL: 0CVE-2016-7426 – ntp: Client rate limiting and server responses
https://notcve.org/view.php?id=CVE-2016-7426
NTP before 4.2.8p9 rate limits responses received from the configured sources when rate limiting for all associations is enabled, which allows remote attackers to cause a denial of service (prevent responses from the sources) by sending responses with a spoofed source address. NTP en versiones anteriores a 4.2.8p9 limita la clasificación de respuestas recibidas desde las fuentes configuradas cuando la limitación de clasificación para todas las asociaciones está habilitado, lo que permite a atacantes remotos provocar una denegación de servicio (prevenir las respuestas de las fuentes) enviando respuestas con una dirección de origen suplantada. It was found that when ntp is configured with rate limiting for all associations the limits are also applied to responses received from its configured sources. A remote attacker who knows the sources can cause a denial of service by preventing ntpd from accepting valid responses from its sources. • http://nwtime.org/ntp428p9_release http://rhn.redhat.com/errata/RHSA-2017-0252.html http://support.ntp.org/bin/view/Main/NtpBug3071 http://support.ntp.org/bin/view/Main/SecurityNotice#Recent_Vulnerabilities http://www.securityfocus.com/bid/94451 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_na-hpesbux03706en_us https://security.FreeBSD.org/advisories/FreeBSD-SA- • CWE-400: Uncontrolled Resource Consumption •

The read_mru_list function in NTP before 4.2.8p9 allows remote attackers to cause a denial of service (crash) via a crafted mrulist query. La función read_mru_list en NTP en versiones anteriores a 4.2.8p9 permite a atacantes remotos provocar una denegación de servicio (caída) a través de una consulta mrulist manipulada. ntpd versions 4.2.7p22 up to but not including 4.2.8p9 and 4.3.0 up to, but not including 4.3.94 suffer from a remote denial of service vulnerability. The vulnerability allow unauthenticated users to crash ntpd with a single malformed UDP packet, which cause a null pointer dereference. • https://www.exploit-db.com/exploits/40806 https://github.com/opsxcq/exploit-CVE-2016-7434 https://github.com/shekkbuilder/CVE-2016-7434 http://nwtime.org/ntp428p9_release http://support.ntp.org/bin/view/Main/NtpBug3082 http://support.ntp.org/bin/view/Main/SecurityNotice#Recent_Vulnerabilities http://www.securityfocus.com/bid/94448 http://www.securitytracker.com/id/1037354 https://bto.bluecoat.com/security-advisory/sa139 https://h20566.www2.hpe.com/hpsc/doc/public/display?docLoca • CWE-20: Improper Input Validation •
