CVSS: 7.5EPSS: 0%CPEs: 27EXPL: 0CVE-2016-8743 – httpd: Apache HTTP Request Parsing Whitespace Defects
https://notcve.org/view.php?id=CVE-2016-8743
Apache HTTP Server, in all releases prior to 2.2.32 and 2.4.25, was liberal in the whitespace accepted from requests and sent in response lines and headers. Accepting these different behaviors represented a security concern when httpd participates in any chain of proxies or interacts with back-end application servers, either through mod_proxy or using conventional CGI mechanisms, and may result in request smuggling, response splitting and cache pollution. El servidor HTTP Apache, en todas las distribuciones anteriores a la 2.2.32 y la 2.4.25 era liberal en el espacio en blanco aceptado de peticiones y enviado en lineas y cabeceras de respuesta. La aceptación de estos comportamientos diferentes representaba un problema a nivel de seguridad cuando httpd participa en cualquier cadena de proxies o interactúa con servidores de aplicaciones backend, ya sea mediante mod_proxy o utilizando mecanismos CGI convencionales y puede dar lugar al tráfico de peticiones, división de respuestas y contaminación de la caché. It was discovered that the HTTP parser in httpd incorrectly allowed certain characters not permitted by the HTTP protocol specification to appear unencoded in HTTP request headers. • http://rhn.redhat.com/errata/RHSA-2017-1415.html http://www.debian.org/security/2017/dsa-3796 http://www.securityfocus.com/bid/95077 http://www.securitytracker.com/id/1037508 https://access.redhat.com/errata/RHSA-2017:0906 https://access.redhat.com/errata/RHSA-2017:1161 https://access.redhat.com/errata/RHSA-2017:1413 https://access.redhat.com/errata/RHSA-2017:1414 https://access.redhat.com/errata/RHSA-2017:1721 https://h20566.www2.hpe.com/hpsc/doc/public/display • CWE-20: Improper Input Validation •
CVSS: 5.3EPSS: 0%CPEs: 125EXPL: 0CVE-2016-2518 – ntp: out-of-bounds references on crafted packet
https://notcve.org/view.php?id=CVE-2016-2518
The MATCH_ASSOC function in NTP before version 4.2.8p9 and 4.3.x before 4.3.92 allows remote attackers to cause an out-of-bounds reference via an addpeer request with a large hmode value. La función MATCH_ASSOC en NTP en versiones anteriores 4.2.8p9 y 4.3.x en versiones anteriores a 4.3.92 permite a atacantes remotos provocar una referencia fuera de los límites a través de una solicitud addpeer con un valor hmode grande. An out-of-bounds access flaw was found in the way ntpd processed certain packets. An authenticated attacker could use a crafted packet to create a peer association with hmode of 7 and larger, which could potentially (although highly unlikely) cause ntpd to crash. • http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183647.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/184669.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/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2016& • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2015-7977
ntpd in NTP before 4.2.8p6 and 4.3.x before 4.3.90 allows remote attackers to cause a denial of service (NULL pointer dereference) via a ntpdc reslist command. ntpd en NTP en versiones anteriores a 4.2.8p6 y 4.3.x en versiones anteriores a 4.3.90 permite a atacantes remotos provocar una denegación de servicio (referencia a puntero NULL) mediante un comando ntpdc reslist. A NULL pointer dereference flaw was found in the way ntpd processed 'ntpdc reslist' commands that queried restriction lists with a large amount of entries. A remote attacker could potentially use this flaw to crash ntpd. • http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177507.html http://lists.fedoraproject.org/pipermail/package-announce/2016-January/176434.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-announce/2016-05/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00038.html http://lists.opensuse.org/opensuse-security-announce&# • CWE-476: NULL Pointer Dereference •
CVSS: 7.7EPSS: 0%CPEs: 29EXPL: 1CVE-2015-7974 – ntp: missing key check allows impersonation between authenticated peers (VU#357792)
https://notcve.org/view.php?id=CVE-2015-7974
NTP 4.x before 4.2.8p6 and 4.3.x before 4.3.90 do not verify peer associations of symmetric keys when authenticating packets, which might allow remote attackers to conduct impersonation attacks via an arbitrary trusted key, aka a "skeleton key." NTP 4.x en versiones anteriores a 4.2.8p6 y 4.3.x en versiones anteriores a 4.3.90 no verifica las asociaciones del par de las claves simétricas cuando autentica paquetes, lo que podría permitir a atacante remotos llevar a cabo ataques de suplantación de identidad a través de una clave de confianza arbitraria, también conocida como "skeleton key". A flaw was found in the way NTP verified trusted keys during symmetric key authentication. An authenticated client (A) could use this flaw to modify a packet sent between a server (B) and a client (C) using a key that is different from the one known to the client (A). • http://bugs.ntp.org/show_bug.cgi?id=2936 http://rhn.redhat.com/errata/RHSA-2016-2583.html http://support.ntp.org/bin/view/Main/NtpBug2936 http://www.debian.org/security/2016/dsa-3629 http://www.securityfocus.com/bid/81960 http://www.securitytracker.com/id/1034782 http://www.talosintel.com/reports/TALOS-2016-0071 https://cert-portal.siemens.com/productcert/pdf/ssa-497656.pdf https://h20566.www2.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbhf03750e • CWE-287: Improper Authentication CWE-304: Missing Critical Step in Authentication •
