https://notcve.org/view.php?id=CVE-2015-5194
The log_config_command function in ntp_parser.y in ntpd in NTP before 4.2.7p42 allows remote attackers to cause a denial of service (ntpd crash) via crafted logconfig commands. La función log_config_command en el archivo ntp_parser.y en ntpd en NTP anterior a versión 4.2.7p42, permite a los atacantes remotos causar una denegación de servicio (bloqueo de ntpd) por medio de comandos logconfig creados. It was found that ntpd could crash due to an uninitialized variable when processing malformed logconfig configuration commands. • http://bk1.ntp.org/ntp-dev/?PAGE=patch&REV=4c4fc141LwvcoGp-lLGhkAFp3ZvtrA http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170926.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169167.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00048.html http://lists.opensuse.org/opensuse-security-announce/2016-07/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00042.html http://rhn.redhat.com/errata/RHSA-2016-0780. • CWE-20: Improper Input Validation CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2015-5219
The ULOGTOD function in ntp.d in SNTP before 4.2.7p366 does not properly perform type conversions from a precision value to a double, which allows remote attackers to cause a denial of service (infinite loop) via a crafted NTP packet. La función ULOGTOD en el archivo ntp.d en SNTP en versiones anteriores a la 4.2.7p366 no realiza apropiadamente las conversiones de tipo de un valor de precisión a uno doble, lo que permite a los atacantes remotos causar una denegación de servicio (bucle infinito) por medio de un paquete NTP creado. It was discovered that the sntp utility could become unresponsive due to being caught in an infinite loop when processing a crafted NTP packet. • http://aix.software.ibm.com/aix/efixes/security/ntp_advisory4.asc http://bk1.ntp.org/ntp-dev/?PAGE=patch&REV=51786731Gr4-NOrTBC_a_uXO4wuGhg http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170926.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169167.html http://lists.fedoraproject.org/pipermail/package-announce/2015-September/166992.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00048.html http://lists.opensuse.org/opensuse-updates&#x • CWE-704: Incorrect Type Conversion or Cast CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVSS: 7.5EPSS: 5%CPEs: 38EXPL: 0CVE-2015-5300 – ntp: MITM attacker can force ntpd to make a step larger than the panic threshold
https://notcve.org/view.php?id=CVE-2015-5300
The panic_gate check in NTP before 4.2.8p5 is only re-enabled after the first change to the system clock that was greater than 128 milliseconds by default, which allows remote attackers to set NTP to an arbitrary time when started with the -g option, or to alter the time by up to 900 seconds otherwise by responding to an unspecified number of requests from trusted sources, and leveraging a resulting denial of service (abort and restart). La comprobación panic_gate en NTP anterior a versión 4.2.8p5 es solo habilitada nuevamente después del primer cambio al reloj del sistema que fue mayor que 128 milisegundos por defecto, permitiendo a los atacantes remotos fijar el NTP a un tiempo arbitrario cuando arranca con la opción -g, o alterar el tiempo hasta 900 segundos, de lo contrario por respuesta a un número no especificado de peticiones de fuentes de confianza y aprovechando una denegación de servicio resultante (anular y reiniciar). It was found that ntpd did not correctly implement the threshold limitation for the '-g' option, which is used to set the time without any restrictions. A man-in-the-middle attacker able to intercept NTP traffic between a connecting client and an NTP server could use this flaw to force that client to make multiple steps larger than the panic threshold, effectively changing the time to an arbitrary value at any time. • http://aix.software.ibm.com/aix/efixes/security/ntp_advisory5.asc http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170684.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170926.html http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177507.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00060.html http://lists.opensuse.org/opensuse-security-announc • CWE-20: Improper Input Validation CWE-361: 7PK - Time and State •

https://notcve.org/view.php?id=CVE-2015-1819
The xmlreader in libxml allows remote attackers to cause a denial of service (memory consumption) via crafted XML data, related to an XML Entity Expansion (XEE) attack. Vulnerabilidad en el xmlreader en libxml, permite a atacantes remotos causar una denegación de servicio (consumo de memoria) a través de datos XML manipulados, relacionada con un ataque XML Entity Expansión (XEE). A denial of service flaw was found in the way the libxml2 library parsed certain XML files. An attacker could provide a specially crafted XML file that, when parsed by an application using libxml2, could cause that application to use an excessive amount of memory. • http://lists.apple.com/archives/security-announce/2016/Mar/msg00000.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00001.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00002.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00004.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172710.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172943.html http://lists.opensuse.org/opensuse-updates/2015- • CWE-399: Resource Management Errors •
CVSS: 7.9EPSS: 0%CPEs: 42EXPL: 0CVE-2015-3900 – rubygems: DNS hijacking vulnerability in api_endpoint()
https://notcve.org/view.php?id=CVE-2015-3900
RubyGems 2.0.x before 2.0.16, 2.2.x before 2.2.4, and 2.4.x before 2.4.7 does not validate the hostname when fetching gems or making API requests, which allows remote attackers to redirect requests to arbitrary domains via a crafted DNS SRV record, aka a "DNS hijack attack." RubyGems 2.0.x en versiones anteriores a 2.0.16, 2.2.x en versiones anteriores a 2.2.4 y 2.4.x en versiones anteriores a 2.4.7 no valida el nombre de host al recuperar gemas o hacer solicitudes de API, lo que permite a atacantes remotos redireccionar peticiones a dominios arbitrarios a través del registro DNS SRV manipulado, también conocido como un "ataque de secuestro de DNS". A flaw was found in a way rubygems verified the API endpoint hostname retrieved through a DNS SRV record. A man-in-the-middle attacker could use this flaw to force a client to download content from an untrusted domain. • http://blog.rubygems.org/2015/05/14/CVE-2015-3900.html http://lists.fedoraproject.org/pipermail/package-announce/2015-August/163502.html http://lists.fedoraproject.org/pipermail/package-announce/2015-August/163600.html http://lists.fedoraproject.org/pipermail/package-announce/2015-August/164236.html http://rhn.redhat.com/errata/RHSA-2015-1657.html http://www.openwall.com/lists/oss-security/2015/06/26/2 http://www.oracle.com/technetwork/topics/security/bulletinoct2015-2511968.html http:// • CWE-254: 7PK - Security Features CWE-345: Insufficient Verification of Data Authenticity •
