Files with the .JNLP extension used for "Java web start" applications are not treated as executable content for download prompts even though they can be executed if Java is installed on the local system. This could allow users to mistakenly launch an executable binary locally. This vulnerability affects Firefox < 67.
Los archivos con la extensión .JNLP utilizada para las aplicaciones "Java web start" no se tratan como contenido ejecutable para las solicitudes de descarga, aunque se pueden ejecutar si Java está instalado en el sistema local. Esto podría permitir a los usuarios lanzar de forma local un binario ejecutable. Esta vulnerabilidad afecta a Firefox anterior a 67.
Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, spoof the browser UI, trick the user in to launching local executable binaries, obtain sensitive information, conduct cross-site scripting attacks, or execute arbitrary code. Various other issues were also addressed.
