CVE-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 •
CVE-2016-5844 – libarchive: undefined behaviour (integer overflow) in iso parser
https://notcve.org/view.php?id=CVE-2016-5844
Integer overflow in the ISO parser in libarchive before 3.2.1 allows remote attackers to cause a denial of service (application crash) via a crafted ISO file. Desbordamiento de entero en el analizador ISO en libarchive en versiones anteriores a 3.2.1 permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) a través de un archivo ISO manipulado. Undefined behavior (signed integer overflow) was discovered in libarchive, in the ISO parser. A crafted file could potentially cause denial of service. • http://rhn.redhat.com/errata/RHSA-2016-1844.html http://rhn.redhat.com/errata/RHSA-2016-1850.html http://www.debian.org/security/2016/dsa-3657 http://www.openwall.com/lists/oss-security/2016/06/23/6 http://www.openwall.com/lists/oss-security/2016/06/24/4 http://www.oracle.com/technetwork/topics/security/bulletinjul2016-3090568.html http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016-3090544.html http://www.securityfocus.com/bid/91808 http://www.securityt • CWE-190: Integer Overflow or Wraparound •

wiretap/netscreen.c in the NetScreen file parser in Wireshark 1.12.x before 1.12.12 and 2.x before 2.0.4 mishandles sscanf unsigned-integer processing, which allows remote attackers to cause a denial of service (application crash) via a crafted file. wiretap/netscreen.c en el analizador de archivo NetScreen en Wireshark 1.12.x en versiones anteriores a 1.12.12 y 2.x en versiones anteriores a 2.0.4 no maneja correctamente procesamiento sin signo de entero sscanf, lo que permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) a través de un archivo manipulado. • http://www.debian.org/security/2016/dsa-3615 http://www.openwall.com/lists/oss-security/2016/06/09/3 http://www.oracle.com/technetwork/topics/security/bulletinjul2016-3090568.html http://www.securityfocus.com/bid/91140 https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=12396 https://github.com/wireshark/wireshark/commit/11edc83b98a61e890d7bb01855389d40e984ea82 https://github.com/wireshark/wireshark/commit/6a140eca7b78b230f1f90a739a32257476513c78 https://www.wireshark.org/security/wnpa-sec-2016-36.html • CWE-20: Improper Input Validation •
CVE-2016-4971 – GNU Wget < 1.18 - Arbitrary File Upload
https://notcve.org/view.php?id=CVE-2016-4971
GNU wget before 1.18 allows remote servers to write to arbitrary files by redirecting a request from HTTP to a crafted FTP resource. GNU wget en versiones anteriores a 1.18 permite a servidores remotos escribir archivos arbitrarios redirigiendo una petición desde HTTP a una fuente FTP manipulada. It was found that wget used a file name provided by the server for the downloaded file when following a HTTP redirect to a FTP server resource. This could cause wget to create a file with a different name than expected, possibly allowing the server to execute arbitrary code on the client. GNU Wget versions prior to 1.18 suffer from an arbitrary file upload vulnerability that may allow for remote code execution. • https://www.exploit-db.com/exploits/49815 https://www.exploit-db.com/exploits/40064 https://github.com/gitcollect/CVE-2016-4971 https://github.com/mbadanoiu/CVE-2016-4971 https://github.com/dinidhu96/IT19013756_-CVE-2016-4971- http://git.savannah.gnu.org/cgit/wget.git/commit/?id=e996e322ffd42aaa051602da182d03178d0f13e1 http://lists.gnu.org/archive/html/info-gnu/2016-06/msg00004.html http://lists.opensuse.org/opensuse-updates/2016-08/msg00043.html http://packetstormsecurity.com/files • CWE-73: External Control of File Name or Path •
CVE-2016-2178 – openssl: Non-constant time codepath followed for certain operations in DSA implementation
https://notcve.org/view.php?id=CVE-2016-2178
The dsa_sign_setup function in crypto/dsa/dsa_ossl.c in OpenSSL through 1.0.2h does not properly ensure the use of constant-time operations, which makes it easier for local users to discover a DSA private key via a timing side-channel attack. La función dsa_sign_setup en crypto/dsa/dsa_ossl.c en OpenSSL hasta la versión 1.0.2h no asegura correctamente la utilización de operaciones de tiempo constante, lo que facilita a usuarios locales descubrir una clave privada DSA a través de un ataque de sincronización de canal lateral. It was discovered that OpenSSL did not always use constant time operations when computing Digital Signature Algorithm (DSA) signatures. A local attacker could possibly use this flaw to obtain a private DSA key belonging to another user or service running on the same system. • http://eprint.iacr.org/2016/594.pdf http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00005.html http://lists.opensuse.org& • CWE-203: Observable Discrepancy CWE-385: Covert Timing Channel •
