The rate limiting feature in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to have unspecified impact via a large number of crafted requests. La funcionalidad de limitación de velocidad en NTP 4.x en versiones anteriores a la 4.2.8p4 y 4.3.x en versiones anteriores a la 4.3.77 permite que atacantes remotos provoquen errores sin especificar empleando un gran número de peticiones manipuladas. • http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00034.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00037.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00048.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2016-06 • CWE-20: Improper Input Validation •

Directory traversal vulnerability in the save_config function in ntpd in ntp_control.c in NTP before 4.2.8p4, when used on systems that do not use '\' or '/' characters for directory separation such as OpenVMS, allows remote authenticated users to overwrite arbitrary files. La vulnerabilidad salto de directorio en la función save_config en ntpd en el archivo ntp_control.c en NTP versiones anteriores a 4.2.8p4, cuando es usado en sistemas que no utilizan caracteres "\" o '"/" para la separación de directorios como OpenVMS, permite a usuarios autenticados remotos sobrescribir archivos arbitrarios. • http://support.ntp.org/bin/view/Main/NtpBug2918 http://support.ntp.org/bin/view/Main/SecurityNotice http://www.talosintel.com/reports/TALOS-2015-0062 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 7.5EPSS: 6%CPEs: 45EXPL: 0CVE-2015-7701 – ntp: slow memory leak in CRYPTO_ASSOC
https://notcve.org/view.php?id=CVE-2015-7701
Memory leak in the CRYPTO_ASSOC function in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service (memory consumption). Una fuga de memoria en la función CRYPTO_ASSOC en ntpd en NTP 4.2.x en versiones anteriores a 4.2.8p4, y 4.3.x en versiones anteriores a 4.3.77 permite que atacantes remotos provoquen una denegación de servicio (consumo de memoria). A memory leak flaw was found in ntpd's CRYPTO_ASSOC. If ntpd was configured to use autokey authentication, an attacker could send packets to ntpd that would, after several days of ongoing attack, cause it to run out of memory. • http://rhn.redhat.com/errata/RHSA-2016-0780.html http://rhn.redhat.com/errata/RHSA-2016-2583.html http://support.ntp.org/bin/view/Main/NtpBug2909 http://www.debian.org/security/2015/dsa-3388 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.securityfocus.com/bid/77281 http://www.securitytracker.com/id/1033951 https://bugzilla.redhat.com/show_bug.cgi?id=1274255 https://security.gentoo.org/glsa/201607-15 https://security.netapp.com • CWE-401: Missing Release of Memory after Effective Lifetime CWE-772: Missing Release of Resource after Effective Lifetime •
CVSS: 7.5EPSS: 81%CPEs: 58EXPL: 0CVE-2015-7704 – ntp: disabling synchronization via crafted KoD packet
https://notcve.org/view.php?id=CVE-2015-7704
The ntpd client in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service via a number of crafted "KOD" messages. El cliente ntpd en NTP 4.x en versiones anteriores a 4.2.8p4, y 4.3.x en versiones anteriores a 4.3.77 permite que atacantes remotos provoquen una denegación de servicio empleando una serie de mensajes "KOD" manipulados. It was discovered that ntpd as a client did not correctly check timestamps in Kiss-of-Death packets. A remote attacker could use this flaw to send a crafted Kiss-of-Death packet to an ntpd client that would increase the client's polling interval value, and effectively disable synchronization with the server. • http://bugs.ntp.org/show_bug.cgi?id=2901 http://rhn.redhat.com/errata/RHSA-2015-1930.html http://rhn.redhat.com/errata/RHSA-2015-2520.html http://support.ntp.org/bin/view/Main/NtpBug2901 http://support.ntp.org/bin/view/Main/SecurityNotice#October_2015_NTP_4_2_8p4_Securit http://www.debian.org/security/2015/dsa-3388 http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.securityfocus.com/bid/77280 http://www.securitytracker.com/id/1 • CWE-20: Improper Input Validation •

Use-after-free vulnerability in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote authenticated users to possibly execute arbitrary code or cause a denial of service (crash) via crafted packets. Una vulnerabilidad use-after-free en ntpd en NTP 4.2.x en versiones anteriores a la 4.2.8p4, y 4.3.x en versiones anteriores a la 4.3.77 permite que atacantes remotos autenticados tengan la posibilidad de ejecutar código arbitrario o provocar una denegación de servicio utilizando paquetes manipulados. • http://support.ntp.org/bin/view/Main/NtpBug2916 http://www.securityfocus.com/bid/77276 http://www.securitytracker.com/id/1033951 https://bugzilla.redhat.com/show_bug.cgi?id=1274257 https://security.gentoo.org/glsa/201607-15 https://security.netapp.com/advisory/ntap-20171004-0001 • CWE-416: Use After Free •
