A "data:" URL loaded in a new tab did not inherit the Content Security Policy (CSP) of the original page, allowing for bypasses of the policy including the execution of JavaScript. In prior versions when "data:" documents also inherited the context of the original page this would allow for potential cross-site scripting (XSS) attacks. This vulnerability affects Firefox < 57. Una URL "data:" cargada en una nueva pestaña no hereda la política de seguridad de contenido (CSP) de la página original, permitiendo la omisión de la política, incluyendo la ejecución de código JavaScript. Las versiones anteriores, cuando los documentos "data:" también heredaban el contexto de la página original, permitirían ataques Cross-Site Scripting (XSS) potenciales. • http://www.securityfocus.com/bid/101832 http://www.securitytracker.com/id/1039803 https://bugzilla.mozilla.org/show_bug.cgi?id=1358009 https://www.mozilla.org/security/advisories/mfsa2017-24 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

A vulnerability where the security wrapper does not deny access to some exposed properties using the deprecated "_exposedProps_" mechanism on proxy objects. These properties should be explicitly unavailable to proxy objects. This vulnerability affects Firefox < 57. Una vulnerabilidad en la que el wrapper de seguridad no deniega el acceso a determinadas propiedades expuestas usando el mecanismo obsoleto "_exposedProps_" en los objetos proxy. Estas propiedades deberían no estar disponibles explícitamente para los objetos proxy. • http://www.securityfocus.com/bid/101832 http://www.securitytracker.com/id/1039803 https://bugzilla.mozilla.org/show_bug.cgi?id=1392026 https://www.mozilla.org/security/advisories/mfsa2017-24 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

Some Arabic and Indic vowel marker characters can be combined with Latin characters in a domain name to eclipse the non-Latin character with some font sets on the addressbar. The non-Latin character will not be visible to most viewers. This allows for domain spoofing attacks because these combined domain names do not display as punycode. This vulnerability affects Firefox < 57. Algunos caracteres marcas de vocales árabes e indios se pueden combinar con caracteres latinos en un nombre de dominio para eclipsar caracteres no latinos con algunas familias de fuentes en la barra de direcciones. • http://www.securityfocus.com/bid/101832 http://www.securitytracker.com/id/1039803 https://bugzilla.mozilla.org/show_bug.cgi?id=1370497 https://www.mozilla.org/security/advisories/mfsa2017-24 • CWE-20: Improper Input Validation •

JavaScript can be injected into an exported bookmarks file by placing JavaScript code into user-supplied tags in saved bookmarks. If the resulting exported HTML file is later opened in a browser this JavaScript will be executed. This could be used in social engineering and self-cross-site-scripting (self-XSS) attacks if users were convinced to add malicious tags to bookmarks, export them, and then open the resulting file. This vulnerability affects Firefox < 57. Se puede inyectar código JavaScript en un archivo de marcadores exportado colocando código JavaScript en las etiquetas proporcionadas por el usuario en los marcadores guardados. • http://www.securityfocus.com/bid/101832 http://www.securitytracker.com/id/1039803 https://bugzilla.mozilla.org/show_bug.cgi?id=1366420 https://www.mozilla.org/security/advisories/mfsa2017-24 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

Memory safety bugs were reported in Firefox 56. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 57. Se han informado de errores de seguridad de memoria en Firefox 56. Algunos de estos errores mostraron evidencias de corrupción de memoria y se cree que, con el esfuerzo necesario, se podrían explotar para ejecutar código arbitrario. • http://www.securityfocus.com/bid/101832 http://www.securitytracker.com/id/1039803 https://bugzilla.mozilla.org/buglist.cgi?bug_id=1399922%2C1403646%2C1403716%2C1365894%2C1402876%2C1406154%2C1384121%2C1384615%2C1407375%2C1339485%2C1361432%2C1394031%2C1383019%2C1407032%2C1387845%2C1386490 https://www.mozilla.org/security/advisories/mfsa2017-24 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
