CVE-2015-5219 – ntp: infinite loop in sntp processing crafted packet
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 • CWE-704: Incorrect Type Conversion or Cast CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVE-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 •
CVE-2014-8162 – Satellite5: RPC API XML External Entities file disclosure
https://notcve.org/view.php?id=CVE-2014-8162
XML external entity (XXE) in the RPC interface in Spacewalk and Red Hat Network (RHN) Satellite 5.7 and earlier allows remote attackers to read arbitrary files and possibly have other unspecified impact via unknown vectors. Vulnerabilidad de entidad externa XML (XXE) en la interfaz RPC en Spacewalk y Red Hat Network (RHN) Satellite 5.7 y anteriores permite a atacantes remotos leer archivos arbitrarios y posiblemente tener otro impacto no especificado a través de vectores desconocidos. It was found that the RPC interface in Satellite would resolve external entities, allowing an attacker to conduct XML External Entity (XXE) attacks. A remote attacker could use this flaw to read files accessible to the user running the Satellite server, and potentially perform other more advanced XXE attacks. • http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00020.html http://rhn.redhat.com/errata/RHSA-2015-0957.html http://www.securityfocus.com/bid/74595 https://access.redhat.com/security/cve/CVE-2014-8162 https://bugzilla.redhat.com/show_bug.cgi?id=1187339 • CWE-611: Improper Restriction of XML External Entity Reference •
CVE-2015-2808 – SSL/TLS: "Invariance Weakness" vulnerability in RC4 stream cipher
https://notcve.org/view.php?id=CVE-2015-2808
The RC4 algorithm, as used in the TLS protocol and SSL protocol, does not properly combine state data with key data during the initialization phase, which makes it easier for remote attackers to conduct plaintext-recovery attacks against the initial bytes of a stream by sniffing network traffic that occasionally relies on keys affected by the Invariance Weakness, and then using a brute-force approach involving LSB values, aka the "Bar Mitzvah" issue. El algoritmo RC4, utilizado en el protocolo TLS y el protocolo SSL, no combina correctamente los datos de estados con los datos de claves durante la fase de inicialización, lo que facilita a atacantes remotos realizar ataques de recuperación de texto claro contra los bytes iniciales de un flujo mediante la captura de trafico de la red que ocasionalmente depende de claves afectadas por la debilidad de la invariabilidad (Invariance Weakness), y posteriormente utilizar un acercamiento de fuerza bruta que involucra valores LSB, también conocido como el problema de 'Bar Mitzvah'. • http://h20564.www2.hpe.com/hpsc/doc/public/display?docId=emr_na-c04779034 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10705 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10727 http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00013.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00022.html • CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
