Opera, possibly before 9.25, uses the HTTP Host header to determine the context of a document provided in a (1) 4xx or (2) 5xx CONNECT response from a proxy server, which allows man-in-the-middle attackers to execute arbitrary web script by modifying this CONNECT response, aka an "SSL tampering" attack. Opera, posiblemente anteriores a v9.25, utiliza una cabecera HTTP Host para determinar el contexto de un documento propocionado por una respuesta de CONEXIÓN (1) 4xx o (2) 5xx desde un servidor proxy, lo que permite a los atacantes "hombre en el medio" ejecutar arbitrariamente una secuencia de comandos web modificando la respuesta CONEXIÓN, también conocida como un ataque "forzado SSL". • http://research.microsoft.com/apps/pubs/default.aspx?id=79323 http://research.microsoft.com/pubs/79323/pbp-final-with-update.pdf • CWE-287: Improper Authentication •

Multiple buffer overflows in Opera before 9.63 might allow (1) remote attackers to execute arbitrary code via a crafted text area, or allow (2) user-assisted remote attackers to execute arbitrary code via a long host name in a file: URL. NOTE: this might overlap CVE-2008-5178. Múltiples desbordamientos de búfer en versiones de Opera anteriores a la 9.63 podrían permitir (1) a atacantes remotos ejecutar código arbitrario a través de un textarea convenientemente modificada, o permitir (2) con ayuda de los usuarios a atacantes remotos ejecutar código arbitrario a través de un nombre de host demasiado largo en un archivo. • https://www.exploit-db.com/exploits/7135 http://secunia.com/advisories/34294 http://security.gentoo.org/glsa/glsa-200903-30.xml http://securitytracker.com/id?1021457 http://www.opera.com/docs/changelogs/linux/963 http://www.opera.com/support/kb/view/920 http://www.opera.com/support/kb/view/922 http://www.securityfocus.com/archive/1/498452/100/0/threaded http://www.securityfocus.com/archive/1/498481/100/0/threaded http://www.securityfocus.com/archive/1/498499 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
