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. • https://bugzilla.mozilla.org/show_bug.cgi?id=1392955 https://www.mozilla.org/security/advisories/mfsa2019-13 • CWE-20: Improper Input Validation •
