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 •
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 •

https://notcve.org/view.php?id=CVE-2015-0881
CRLF injection vulnerability in Squid before 3.1.1 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via a crafted header in a response. Una vulnerabilidad de inyección CRLF en Squid anterior a versión 3.1.1, permite a los atacantes remotos inyectar encabezados HTTP arbitrarios y conducir ataques de división de respuesta HTTP por medio de un encabezado diseñado en una respuesta. • http://jvn.jp/en/jp/JVN64455813/index.html http://jvndb.jvn.jp/jvndb/JVNDB-2015-000019 •
CVE-2014-6270
https://notcve.org/view.php?id=CVE-2014-6270
Off-by-one error in the snmpHandleUdp function in snmp_core.cc in Squid 2.x and 3.x, when an SNMP port is configured, allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted UDP SNMP request, which triggers a heap-based buffer overflow. Error de superación de límite (off-by-one) en la función snmpHandleUdp en snmp_core.cc en Squid 2.x y 3.x, cuando un puerto SNMP está configurado, permite a atacantes remotos causar una denegación de servicio (caída) o posiblemente ejecutar código arbitrario a través de una solicitud UDP SNMP manipulada, lo que provoca un desbordamiento de buffer basado en memoria dinámica. • http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00040.html http://seclists.org/oss-sec/2014/q3/542 http://seclists.org/oss-sec/2014/q3/550 http://www.oracle.com/technetwork/topics/security/bulletinjul2015-2511963.html http://www.securityfocus.com/bid/69686 http://www.ubuntu.com/usn/USN-2921-1 https://bugzilla.novell.com/show_bug.cgi?id=895773 https://bugzilla.redhat.com/show_bug.cgi • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2014-3609 – squid: assertion failure in Range header processing (SQUID-2014:2)
https://notcve.org/view.php?id=CVE-2014-3609
HttpHdrRange.cc in Squid 3.x before 3.3.12 and 3.4.x before 3.4.6 allows remote attackers to cause a denial of service (crash) via a request with crafted "Range headers with unidentifiable byte-range values." HttpHdrRange.cc en Squid 3.x anterior a 3.3.12 y 3.4.x anterior a 3.4.6 permite a atacantes remotos causar una denegación de servicio (caída) a través de una solicitud con ' cabeceras de rango con valores de rango de bytes no identificables' manipuladas. A flaw was found in the way Squid handled malformed HTTP Range headers. A remote attacker able to send HTTP requests to the Squid proxy could use this flaw to crash Squid. • http://lists.opensuse.org/opensuse-security-announce/2014-09/msg00025.html http://lists.opensuse.org/opensuse-updates/2014-09/msg00029.html http://rhn.redhat.com/errata/RHSA-2014-1147.html http://secunia.com/advisories/60179 http://secunia.com/advisories/60334 http://secunia.com/advisories/61320 http://secunia.com/advisories/61412 http://www.debian.org/security/2014/dsa-3014 http://www.debian.org/security/2015/dsa-3139 http://www.oracle.com/technetwork/topics/security/bulletinj • CWE-20: Improper Input Validation CWE-617: Reachable Assertion •
