Mozilla Firefox before 3.0.16 and 3.5.x before 3.5.6, and SeaMonkey before 2.0.1, allows remote attackers to spoof an SSL indicator for an http URL or a file URL by setting document.location to an https URL corresponding to a site that responds with a No Content (aka 204) status code and an empty body. Mozilla Firefox en versiones anteriores a v3.0.16 y v3.5.x antes de v3.5.6, y SeaMonkey antes de v2.0.1, permite a atacantes remotos suplantar un indicador de SSL para una URL o fichero HTTP URL estableciendo el valor de document.location a una URL https correspondiente a un sitio que responde con un código de estado "No Content" (Código 204) y un cuerpo vacío. • http://secunia.com/advisories/37699 http://secunia.com/advisories/37703 http://secunia.com/advisories/37704 http://secunia.com/advisories/37785 http://secunia.com/advisories/37813 http://secunia.com/advisories/37856 http://secunia.com/advisories/37881 http://securitytracker.com/id?1023342 http://securitytracker.com/id?1023343 http://www.debian.org/security/2009/dsa-1956 http://www.mozilla.org/security/announce/2009/mfsa2009-69.html http://www.novell.com/linux/security/advis •

Mozilla Firefox before 3.0.15 and 3.5.x before 3.5.4, and SeaMonkey before 2.0, does not properly handle a right-to-left override (aka RLO or U+202E) Unicode character in a download filename, which allows remote attackers to spoof file extensions via a crafted filename, as demonstrated by displaying a non-executable extension for an executable file. Mozilla Firefox anteriores a v3.0.15 y v3.5.x anteriores a v3.5.4, y SeaMonkey anteriores a v2.0, no maneja adecuadamente una anulación de carácter Unicode "right-to-left" (también conocido como RLO o U+202E) en un nombre de fichero de descarga, lo que permite a atacantes remotos falsificar las extensiones de fichero a través de un nombre de fichero manipulado como se demuestra en una extensión no ejecutable de un fichero ejecutable. • http://lists.opensuse.org/opensuse-security-announce/2010-06/msg00001.html http://secunia.com/advisories/38977 http://sunsolve.sun.com/search/document.do?assetkey=1-26-272909-1 http://www.mandriva.com/security/advisories?name=MDVSA-2009:294 http://www.mozilla.org/security/announce/2009/mfsa2009-62.html http://www.redhat.com/support/errata/RHSA-2010-0153.html http://www.redhat.com/support/errata/RHSA-2010-0154.html http://www.ubuntu.com/usn/USN-915-1 http://www.vupen.co • CWE-16: Configuration •

Mozilla Firefox 3.0.13 and earlier, 3.5, 3.6 a1 pre, and 3.7 a1 pre; SeaMonkey 1.1.17; and Mozilla 1.7.x and earlier do not properly handle javascript: URIs in HTML links within 302 error documents sent from web servers, which allows user-assisted remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Location HTTP response header or (2) specifying the content of a Location HTTP response header. Mozilla Firefox v3.0.13 y anteriores, v3.5, v3.6 a1 pre, y v3.7 a1 pre; SeaMonkey v1.1.17; y Mozilla v1.7.x y anteriores no manejan de forma adecuada las URIs javascript en los enlaces HTML incluidos en los documentos de error 302 enviados desde servidores web, lo que permite a atacantes remotos asistidos por usuarios realizar un ataque de ejecución de secuencias de comandos en sitios cruzados (XSS) a través de vectores relativos a (1) inyectar una cabecera Location de respuesta HTTP o (2) especificando el contenidos de una cabecera Location de respuesta HTTP. • http://websecurity.com.ua/3373 http://websecurity.com.ua/3386 http://www.securityfocus.com/archive/1/506163/100/0/threaded https://exchange.xforce.ibmcloud.com/vulnerabilities/52995 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
