CVSS: 8.1EPSS: 94%CPEs: 18EXPL: 0CVE-2016-5388 – Tomcat: CGI sets environmental variable based on user supplied Proxy request header
https://notcve.org/view.php?id=CVE-2016-5388
Apache Tomcat 7.x through 7.0.70 and 8.x through 8.5.4, when the CGI Servlet is enabled, follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue. NOTE: the vendor states "A mitigation is planned for future releases of Tomcat, tracked as CVE-2016-5388"; in other words, this is not a CVE ID for a vulnerability. Apache Tomcat, en versiones 7.x hasta la 7.0.70 y versiones 8.x hasta la 8.5.4, cuando el Servlet CGI está habilitado, sigue la sección 4.1.18 de RFC 3875 y, por lo tanto, no protege aplicaciones ante la presencia de datos de cliente no fiables en la variable de entorno HTTP_PROXY. Esto podría permitir que atacantes remotos redirijan el tráfico HTTP saliente de una aplicación a un servidor proxy arbitrario mediante una cabecera Proxy manipulada en una petición HTTP. Esto también se conoce como problema "httpoxy". • http://lists.opensuse.org/opensuse-updates/2016-09/msg00025.html http://rhn.redhat.com/errata/RHSA-2016-1624.html http://rhn.redhat.com/errata/RHSA-2016-2045.html http://rhn.redhat.com/errata/RHSA-2016-2046.html http://www.kb.cert.org/vuls/id/797896 http://www.oracle.com/technetwork/security-advisory/cpujul2017-3236622.html http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2016-3090545.html http://www.securityfocus.com/bid/91818 http://www.securitytracker.com/id/ • CWE-20: Improper Input Validation CWE-284: Improper Access Control •
CVSS: 8.1EPSS: 17%CPEs: 52EXPL: 0CVE-2016-5387 – HTTPD: sets environmental variable based on user supplied Proxy request header
https://notcve.org/view.php?id=CVE-2016-5387
The Apache HTTP Server through 2.4.23 follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue. NOTE: the vendor states "This mitigation has been assigned the identifier CVE-2016-5387"; in other words, this is not a CVE ID for a vulnerability. El Apache HTTP Server hasta la versión 2.4.23 sigue a RFC 3875 sección 4.1.18 y por lo tanto no protege aplicaciones de la presencia de datos de clientes no confiables en ambiente variable de HTTP_PROXY, lo que puede permitir a atacantes remotos redireccionar el tráfico HTTP saliente de aplicación a un servidor proxy arbitrario a través de una cabecera Proxy manipulada en una petición HTTP, también conocido como problema "httpoxy". NOTA: el vendedor afirma "Se ha asignado a esta mitigación el identificador CVE-2016-5387"; en otras palabras, esto no es un CVE ID para una vulnerabilidad. It was discovered that httpd used the value of the Proxy header from HTTP requests to initialize the HTTP_PROXY environment variable for CGI scripts, which in turn was incorrectly used by certain HTTP client implementations to configure the proxy for outgoing HTTP requests. • http://lists.opensuse.org/opensuse-updates/2016-07/msg00059.html http://rhn.redhat.com/errata/RHSA-2016-1624.html http://rhn.redhat.com/errata/RHSA-2016-1625.html http://rhn.redhat.com/errata/RHSA-2016-1648.html http://rhn.redhat.com/errata/RHSA-2016-1649.html http://rhn.redhat.com/errata/RHSA-2016-1650.html http://www.debian.org/security/2016/dsa-3623 http://www.kb.cert.org/vuls/id/797896 http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html • CWE-20: Improper Input Validation •

CVSS: 7.8EPSS: 0%CPEs: 17EXPL: 0CVE-2016-4470 – kernel: Uninitialized variable in request_key handling causes kernel crash in error handling path
https://notcve.org/view.php?id=CVE-2016-4470
The key_reject_and_link function in security/keys/key.c in the Linux kernel through 4.6.3 does not ensure that a certain data structure is initialized, which allows local users to cause a denial of service (system crash) via vectors involving a crafted keyctl request2 command. La función key_reject_and_link en security/keys/key.c en el kernel de Linux hasta la versión 4.6.3 no asegura que cierta estructura de datos esté inicializada, lo que permite a usuarios locales provocar una denegación de servicio (caída del sistema) a través de vectores involucrando un comando keyctl request2 manipulado. A flaw was found in the Linux kernel's keyring handling code: the key_reject_and_link() function could be forced to free an arbitrary memory block. An attacker could use this flaw to trigger a use-after-free condition on the system, potentially allowing for privilege escalation. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=38327424b40bcebe2de92d07312c89360ac9229a http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00009.html http://lists.opensuse.org • CWE-253: Incorrect Check of Function Return Value •
