Descriptions

The navigator.sendBeacon implementation in Mozilla Firefox before 37.0, Firefox ESR 31.x before 31.6, and Thunderbird before 31.6 processes HTTP 30x status codes for redirects after a preflight request has occurred, which allows remote attackers to bypass intended CORS access-control checks and conduct cross-site request forgery (CSRF) attacks via a crafted web site, a similar issue to CVE-2014-8638.

La implementación navigator.sendBeacon en Mozilla Firefox anterior a 37.0, Firefox ESR 31.x anterior a 31.6, y Thunderbird anterior a 31.6 procesa los códigos del estatus HTTP 30x para redirecciones después de se ha ocurrido una solicitud de prevuelo, lo que permite a atacantes remotos evadir las comprobaciones de control de acceso a CORS y realizar ataques de CSRF a través de un sitio web manipulado, un problema similar a CVE-2014-8638.

A flaw was found in the Beacon interface implementation in Firefox. A web page containing malicious content could allow a remote attacker to conduct a Cross-Site Request Forgery (CSRF) attack.

Mozilla Firefox is an open source web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox. Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. A flaw was found in the way documents were loaded via resource URLs in, for example, Mozilla's PDF.js PDF file viewer. An attacker could use this flaw to bypass certain restrictions and under certain conditions even execute arbitrary code with the privileges of the user running Firefox.
