CVSS: 5.3EPSS: 2%CPEs: 1EXPL: 0CVE-2016-7433 – ntp: Broken initial sync calculations regression
https://notcve.org/view.php?id=CVE-2016-7433
NTP before 4.2.8p9 does not properly perform the initial sync calculations, which allows remote attackers to unspecified impact via unknown vectors, related to a "root distance that did not include the peer dispersion." NTP en versiones anteriores a 4.2.8p9 no realiza adecuadamente los cálculos de sincronización inicial, lo que permite a atacantes remotos un impacto no especificado a través de vectores desconocidos, relacionado con una "distancia de raíz que no incluía la dispersión de pares". A flaw was found in the way ntpd calculated the root delay. A remote attacker could send a specially-crafted spoofed packet to cause denial of service or in some special cases even crash. • http://lists.opensuse.org/opensuse-updates/2016-12/msg00153.html http://nwtime.org/ntp428p9_release http://rhn.redhat.com/errata/RHSA-2017-0252.html http://support.ntp.org/bin/view/Main/NtpBug3067 http://support.ntp.org/bin/view/Main/SecurityNotice#Recent_Vulnerabilities http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20171129-01-ntpd-en http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/archive/1/539955/100/0/threaded • CWE-682: Incorrect Calculation •

https://notcve.org/view.php?id=CVE-2016-9311
ntpd in NTP before 4.2.8p9, when the trap service is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted packet. ntpd en NTP en versiones anteriores a 4.2.8p9, cuando el servicio de captura está habilitado, permite a atacantes remotos provocar una denegación de servicio (referencia a puntero NULL y caída) a través de un paquete manipulado. A flaw was found in the way ntpd implemented the trap service. A remote attacker could send a specially crafted packet to cause a null pointer dereference that will crash ntpd, resulting in a denial of service. • http://nwtime.org/ntp428p9_release http://rhn.redhat.com/errata/RHSA-2017-0252.html http://support.ntp.org/bin/view/Main/NtpBug3119 http://support.ntp.org/bin/view/Main/SecurityNotice#Recent_Vulnerabilities http://www.securityfocus.com/bid/94444 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-476: NULL Pointer Dereference •
