Opera 9 drops DNS pins based on failed connections to irrelevant TCP ports, which makes it easier for remote attackers to conduct DNS rebinding attacks, as demonstrated by a port 81 URL in an IMG SRC, when the DNS pin had been established for a session on port 80. Opera 9 descarta asignaciones DNS fijas basándose en conexiones fallidas a puertos TCP irrelevantes, lo cual facilita a atacantes remotos llevar a cabo ataques de revinculación DNS, como se ha demostrado mediante un URL con puerto 81 en un SRC de IMG, cuando la asignación DNS ha sido establecida para una sesión en el puerto 80. • http://crypto.stanford.edu/dns/dns-rebinding.pdf http://osvdb.org/45526 •

The child frames in Opera 9 before 9.20 inherit the default charset from the parent window when a charset is not specified in an HTTP Content-Type header or META tag, which allows remote attackers to conduct cross-site scripting (XSS) attacks, as demonstrated using the UTF-7 character set. Los marcos secundarios en Opera 9 antes de la versión 9.20 heredan el conjunto de caracteres por defecto de la ventana principal cuando no se especifica un conjunto de caracteres en un encabezado de tipo de contenido HTTP o etiqueta META, lo que permite a los atacantes remotos conducir ataques de tipo cross-site scripting (XSS), como se demuestra utilizando el conjunto de caracteres UTF-7. • http://osvdb.org/32118 http://secunia.com/advisories/24312 http://secunia.com/advisories/25027 http://www.hardened-php.net/advisory_032007.142.html http://www.novell.com/linux/security/advisories/2007_28_opera.html http://www.opera.com/support/search/view/855 http://www.securityfocus.com/archive/1/461076/100/0/threaded http://www.securityfocus.com/bid/22701 http://www.securitytracker.com/id?1017909 http://www.vupen.com/english/advisories/2007/0745 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
