CVE-2013-4115 – squid: buffer overflow when processing overly long DNS names (SQUID-2013:2)
https://notcve.org/view.php?id=CVE-2013-4115
Buffer overflow in the idnsALookup function in dns_internal.cc in Squid 3.2 through 3.2.11 and 3.3 through 3.3.6 allows remote attackers to cause a denial of service (memory corruption and server termination) via a long name in a DNS lookup request. Desbordamiento de búfer en la función idnsALookup en dns_internal.cc en Squid v3.2 hasta v3.2.11 y v3.3 hasta v3.3.6, lo que permite a atacantes remotos provocar una denegación de servicio (corrupción de memoria o finalización de servicio) a través de un nombre largo en una petición “DNS lookup”. A buffer overflow flaw was found in Squid's DNS lookup module. 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/2016-08/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00040.html http://lists.opensuse.org/opensuse-updates/2013-09/msg00024.html http://lists.opensuse.org/opensuse-updates/2013-09/msg00025.html http://lists.opensuse.org/opensuse-updates/2013-09/msg00030.html http://lists.opensuse.org/opensuse-updates/2013-09/msg00032.html http://lists.opensuse.org/opensuse-updates/2013-09/msg00033.html http://secunia.com/advi • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

CVE-2012-2213 – McAfee Web Gateway And Squid Proxy 3.1.19 Bypass
https://notcve.org/view.php?id=CVE-2012-2213
Squid 3.1.9 allows remote attackers to bypass the access configuration for the CONNECT method by providing an arbitrary allowed hostname in the Host HTTP header. NOTE: this issue might not be reproducible, because the researcher is unable to provide a squid.conf file for a vulnerable system, and the observed behavior is consistent with a squid.conf file that was (perhaps inadvertently) designed to allow access based on a "req_header Host" acl regex that matches www.uol.com.br ** EN DISPUTA ** Squid v3.1.9 permite a atacantes remotos evitar la configuración de acceso para el método CONNECT, proporcionando un nombre de host arbitrario en la cabecera 'host HTTP'. NOTA: este problema no puede ser reproducible, porque el investigador es incapaz de proporcionar un archivo squid.conf de un sistema vulnerable, y el comportamiento observado es consistente con un archivo squid.conf que fue (tal vez sin darse cuenta), diseñado para permitir el acceso basado en una expresión regular de ACL "host req_header" que coincide con www.uol.com.br. • http://archives.neohapsis.com/archives/bugtraq/2012-04/0117.html http://archives.neohapsis.com/archives/bugtraq/2012-04/0131.html http://archives.neohapsis.com/archives/bugtraq/2012-04/0140.html http://archives.neohapsis.com/archives/bugtraq/2012-04/0146.html http://archives.neohapsis.com/archives/bugtraq/2012-04/0163.html http://archives.neohapsis.com/archives/bugtraq/2012-04/0165.html • CWE-264: Permissions, Privileges, and Access Controls •
