CVE-2016-2570 – squid: some code paths fail to check bounds in string object
https://notcve.org/view.php?id=CVE-2016-2570
The Edge Side Includes (ESI) parser in Squid 3.x before 3.5.15 and 4.x before 4.0.7 does not check buffer limits during XML parsing, which allows remote HTTP servers to cause a denial of service (assertion failure and daemon exit) via a crafted XML document, related to esi/CustomParser.cc and esi/CustomParser.h. El analizador de Edge Side Includes (ESI) en Squid 3.x en versiones anteriores a 3.5.15 y 4.x en versiones anteriores a 4.0.7 no comprueba los limites del buffer durante el análisis gramatical XML, lo que permite a servidores HTTP remotos provocar una denegación de servicio (fallo de aserción y salida de demonio) a través de un documento XML manipulado, relacionado con esi/CustomParser.cc y esi/CustomParser.h. Incorrect boundary checks were found in the way squid handled headers in HTTP responses, which could lead to an assertion failure. A malicious HTTP server could use this flaw to crash squid using a specially crafted HTTP response. • 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://rhn.redhat.com/errata/RHSA-2016-2600.html http://www.openwall.com/lists/oss-security/2016/02/26/2 http://www.securitytracker.com/id/1035101 http://www.squid-cache.org/Advisories/SQUID-2016_2.txt http://www.squid-cache.org/Versions/v3/3.5/changesets/squid-3 • CWE-20: Improper Input Validation CWE-617: Reachable Assertion •
CVE-2016-2571 – squid: wrong error handling for malformed HTTP responses
https://notcve.org/view.php?id=CVE-2016-2571
http.cc in Squid 3.x before 3.5.15 and 4.x before 4.0.7 proceeds with the storage of certain data after a response-parsing failure, which allows remote HTTP servers to cause a denial of service (assertion failure and daemon exit) via a malformed response. http.cc en Squid 3.x en versiones anteriores a 3.5.15 y 4.x en versiones anteriores a 4.0.7 procede con el almacenamiento de ciertos datos después de un fallo de respuesta de análisis, lo que permite a servidores HTTP remotos provocar una denegación de servicio (fallo de aserción y salida de demonio) a través de una respuesta mal formada. It was found that squid did not properly handle errors when failing to parse an HTTP response, possibly leading to an assertion failure. A malicious HTTP server could use this flaw to crash squid using a specially crafted HTTP response. • 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://rhn.redhat.com/errata/RHSA-2016-2600.html http://www.debian.org/security/2016/dsa-3522 http://www.openwall.com/lists/oss-security/2016/02/26/2 http://www.securitytracker.com/id/1035101 http://www.squid-cache.org/Advisories/SQUID-2016_2.txt http://www.s • CWE-20: Improper Input Validation CWE-228: Improper Handling of Syntactically Invalid Structure •

https://notcve.org/view.php?id=CVE-2014-9749
Squid 3.4.4 through 3.4.11 and 3.5.0.1 through 3.5.1, when Digest authentication is used, allow remote authenticated users to retain access by leveraging a stale nonce, aka "Nonce replay vulnerability." Squid 3.4.4 hasta la versión 3.4.11 y 3.5.0.1 hasta la versión 3.5.1, cuando es utilizada la autenticación Digest, permiten a usuarios remotos autenticados retener el acceso aprovechando un nonce caducado, también conocido como 'Nonce replay vulnerability'. • http://bugs.squid-cache.org/show_bug.cgi?id=4066 http://lists.opensuse.org/opensuse-updates/2015-10/msg00052.html http://www.openwall.com/lists/oss-security/2015/10/01/1 http://www.openwall.com/lists/oss-security/2015/10/11/4 http://www.openwall.com/lists/oss-security/2015/10/12/2 • CWE-264: Permissions, Privileges, and Access Controls •
CVE-2015-5400
https://notcve.org/view.php?id=CVE-2015-5400
Squid before 3.5.6 does not properly handle CONNECT method peer responses when configured with cache_peer, which allows remote attackers to bypass intended restrictions and gain access to a backend proxy via a CONNECT request. Vulnerabilidad en Squid en versiones anteriores a 3.5.6, no maneja adecuadamente las respuestas de pares del método CONNECT cuando se configura con cache_peer, lo que permite a atacantes remotos eludir las restricciones previstas y obtener acceso a un proxy backend a través de una solicitud CONNECT. • http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183598.html 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/2015/dsa-3327 http://www.openwall.com/lists/oss-security/2015/07/06/8 http://www.openwall.com/lists/oss-security/2015/07/09/12 http://www.openwall.com/lists • CWE-264: Permissions, Privileges, and Access Controls •
CVE-2015-3455 – squid: incorrect X509 server certificate validation (SQUID-2015:1)
https://notcve.org/view.php?id=CVE-2015-3455
Squid 3.2.x before 3.2.14, 3.3.x before 3.3.14, 3.4.x before 3.4.13, and 3.5.x before 3.5.4, when configured with client-first SSL-bump, do not properly validate the domain or hostname fields of X.509 certificates, which allows man-in-the-middle attackers to spoof SSL servers via a valid certificate. Squid 3.2.x en versiones anteriores a 3.2.14, 3.3.x en versiones anteriores a 3.3.14, 3.4.x en versiones anteriores a 3.4.13 y 3.5.x en versiones anteriores a 3.5.4, cuando el primer cliente está configurado mediante SSL-bump, no valida adecuadamente el dominio o campos de nombre de host de certificados X.509, lo que permite a atacantes man-in-the-middle suplantar servidores SSL a través de un certificado válido. It was found that Squid configured with client-first SSL-bump did not correctly validate X.509 server certificate host name fields. A man-in-the-middle attacker could use this flaw to spoof a Squid server using a specially crafted X.509 certificate. • http://advisories.mageia.org/MGASA-2015-0191.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183598.html http://lists.opensuse.org/opensuse-updates/2015-09/msg00016.html http://lists.opensuse.org/opensuse-updates/2016-08/msg00069.html http://rhn.redhat.com/errata/RHSA-2015-2378.html http://www.mandriva.com/security/advisories?name=MDVSA-2015:230 http://www.oracle.com/technetwork/topics/security/bulletinjul2015-2511963.html http://www.oracle.com/technetwork/topics/security • CWE-20: Improper Input Validation CWE-297: Improper Validation of Certificate with Host Mismatch •
