CVSS: 8.6EPSS: 0%CPEs: 7EXPL: 0CVE-2016-4554 – squid: Header Smuggling issue in HTTP Request processing
https://notcve.org/view.php?id=CVE-2016-4554
mime_header.cc in Squid before 3.5.18 allows remote attackers to bypass intended same-origin restrictions and possibly conduct cache-poisoning attacks via a crafted HTTP Host header, aka a "header smuggling" issue. mime_header.cc en Squid en versiones anteriores a 3.5.18 permite a atacantes remotos eludir restricciones destinadas al mismo origen y posiblemente llevar a cabo ataques de envenenamiento de caché a través de una cabecera HTTP Host manipulada, también conocido como un problema "contrabando de peticiones". An input validation flaw was found in Squid's mime_get_header_field() function, which is used to search for headers within HTTP requests. An attacker could send an HTTP request from the client side with specially crafted header Host header that bypasses same-origin security protections, causing Squid operating as interception or reverse-proxy to contact the wrong origin server. It could also be used for cache poisoning for client not following RFC 7230. • http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00040.html http://lists.opensuse.org/opensuse-updates/2016-08/msg00069.html http://www.debian.org/security/2016/dsa-3625 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.securitytracker.com/id/1035769 http://www.squid-cache.org/Advisories/SQUID-2016_8.txt http://www.squid-cache.org/Versions/v3/3.1/changesets&# • CWE-20: Improper Input Validation CWE-345: Insufficient Verification of Data Authenticity •

Double free vulnerability in Esi.cc in Squid 3.x before 3.5.18 and 4.x before 4.0.10 allows remote servers to cause a denial of service (crash) via a crafted Edge Side Includes (ESI) response. Vulnerabilidad de liberación doble de memoria en Esi.cc en Squid 3.x en versiones anteriores a 3.5.18 y 4.x en versiones anteriores a 4.0.10 permite a servidores remotos provocar una denegación de servicio (caída) a través de una respuesta Edge Side Includes (ESI) manipulada. An incorrect reference counting flaw was found in the way Squid processes ESI responses. If Squid is configured as reverse-proxy, for TLS/HTTPS interception, an attacker controlling a server accessed by Squid, could crash the squid worker, causing a Denial of Service attack. • http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00040.html http://lists.opensuse.org/opensuse-updates/2016-08/msg00069.html http://www.debian.org/security/2016/dsa-3625 http://www.openwall.com/lists/oss-security/2016/05/06/3 http://www.openwall.com/lists/oss-security/2016/05/06/5 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.securitytracker.com/ • CWE-20: Improper Input Validation •

Multiple stack-based buffer overflows in Squid 3.x before 3.5.17 and 4.x before 4.0.9 allow remote HTTP servers to cause a denial of service or execute arbitrary code via crafted Edge Side Includes (ESI) responses. Múltiples desbordamientos de buffer basado en pila en Squid 3.x en versiones anteriores a 3.5.17 y 4.x en versiones anteriores a 4.0.9 permiten a servidores HTTP remotos provocar una denegación de servicio o ejecutar código arbitrario a través de respuestas Edge Side Includes (ESI) manipuladas. Buffer overflow and input validation flaws were found in the way Squid processed ESI responses. If Squid was used as a reverse proxy, or for TLS/HTTPS interception, a remote attacker able to control ESI components on an HTTP server could use these flaws to crash Squid, disclose parts of the stack memory, or possibly execute arbitrary code as the user running Squid. • http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00040.html http://lists.opensuse.org/opensuse-updates/2016-08/msg00069.html http://www.debian.org/security/2016/dsa-3625 http://www.openwall.com/lists/oss-security/2016/04/20/6 http://www.openwall.com/lists/oss-security/2016/04/20/9 http://www.oracle.com/technetwork/security-advisory/cpujul2016-2881720.html http://www.oracle.com/technetwork/t • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
