CVE-2016-10002 – squid: Information disclosure in HTTP request processing
https://notcve.org/view.php?id=CVE-2016-10002
Incorrect processing of responses to If-None-Modified HTTP conditional requests in Squid HTTP Proxy 3.1.10 through 3.1.23, 3.2.0.3 through 3.5.22, and 4.0.1 through 4.0.16 leads to client-specific Cookie data being leaked to other clients. Attack requests can easily be crafted by a client to probe a cache for this information. Procesamiento incorrecto de respuestas a peticiones condicionales If-None-Modified HTTP en Squid HTTP Proxy 3.1.10 hasta la versión 3.1.23, 3.2.0.3 hasta la versión 3.5.22 y 4.0.1 hasta la versión 4.0.16 conduce a que datos Cookie de un cliente específico sean filtrados a otros clientes. Peticiones de ataque pueden ser fácilmente manipuladas por un cliente para probar una memoria caché para esta información. It was found that squid did not properly remove connection specific headers when answering conditional requests using a cached request. • http://rhn.redhat.com/errata/RHSA-2017-0182.html http://rhn.redhat.com/errata/RHSA-2017-0183.html http://www.debian.org/security/2016/dsa-3745 http://www.openwall.com/lists/oss-security/2016/12/18/1 http://www.securityfocus.com/bid/94953 http://www.securitytracker.com/id/1037513 http://www.squid-cache.org/Advisories/SQUID-2016_11.txt https://access.redhat.com/security/cve/CVE-2016-10002 https://bugzilla.redhat.com/show_bug.cgi?id=1405941 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2016-4553 – squid: Cache poisoning issue in HTTP Request handling
https://notcve.org/view.php?id=CVE-2016-4553
client_side.cc in Squid before 3.5.18 and 4.x before 4.0.10 does not properly ignore the Host header when absolute-URI is provided, which allows remote attackers to conduct cache-poisoning attacks via an HTTP request. client_side.cc en Squid en versiones anteriores a 3.5.18 y 4.x en versiones anteriores a 4.0.10 no ignora correctamente la cabecera Host cuando se proporciona una URI absoluta, lo que permite a atacantes remotos llevar a cabo ataques de envenenamiento de caché a través de una petición HTTP. An input validation flaw was found in the way Squid handled intercepted HTTP Request messages. An attacker could use this flaw to bypass the protection against issues related to CVE-2009-0801, and perform cache poisoning attacks on Squid. • http://bugs.squid-cache.org/show_bug.cgi?id=4501 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/1035768 http://www.squid-cache.org/Advisories/SQUID-2016_7.txt http& • CWE-20: Improper Input Validation CWE-345: Insufficient Verification of Data Authenticity •
CVE-2016-4555 – squid: SegFault from ESIInclude::Start
https://notcve.org/view.php?id=CVE-2016-4555
client_side_request.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 crafted Edge Side Includes (ESI) responses. client_side_request.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 respuestas Edge Side Includes (ESI) manipuladas. A NULL pointer dereference flaw was found in the way Squid processes ESI responses. If Squid was used as a reverse proxy or for TLS/HTTPS interception, a malicious server could use this flaw to crash the Squid worker process. • http://bugs.squid-cache.org/show_bug.cgi?id=4455 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/linu • CWE-20: Improper Input Validation CWE-476: NULL Pointer Dereference •
CVE-2016-4556 – squid: SIGSEGV in ESIContext response handling
https://notcve.org/view.php?id=CVE-2016-4556
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 •
CVE-2016-4053 – squid: multiple issues in ESI processing
https://notcve.org/view.php?id=CVE-2016-4053
Squid 3.x before 3.5.17 and 4.x before 4.0.9 allow remote attackers to obtain sensitive stack layout information via crafted Edge Side Includes (ESI) responses, related to incorrect use of assert and compiler optimization. Squid 3.x en versiones anteriores a 3.5.17 y 4.x en versiones anteriores a 4.0.9 permite a atacantes remotos obtener información sensible sobre la estructura de pila a través de respuestas Edge Side Includes (ESI) manipuladas, relacionado con el uso incorrecto de assert y optimización del compilador. 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 •
