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 •
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 •
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 •

https://notcve.org/view.php?id=CVE-2016-7434
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 •
