Descriptions

Windows 10 does not warn users before opening executable files with the SettingContent-ms extension even when they have been downloaded from the internet and have the "Mark of the Web." Without the warning, unsuspecting users unfamiliar with this new file type might run an unwanted executable. This also allows a WebExtension with the limited downloads.open permission to execute arbitrary code without user interaction on Windows 10 systems. *Note: this issue only affects Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 60, Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61.

Windows 10 no advierte a los usuarios antes de abrir archivos ejecutables con la extensión SettingContent-ms incluso aunque hayan sido descargados de Internet y tengan la "marca de la web". Sin la advertencia, los usuarios incautos que no están familiarizados con este nuevo tipo de archivo podrían ejecutar un archivo no deseado. Esto también permite que una WebExtension con el permiso limitado downloads.open ejecute código arbitrario sin interacción del usuario en sistemas Windows 10. Nota: este problema solo afecta a sistemas operativos Windows. Otros sistemas operativos no se han visto afectados *. La vulnerabilidad afecta a Thunderbird en versiones anteriores a la 60 y la 52.9, Firefox ESR en versiones anteriores a la 60.1 y la 52.9 y Firefox en versiones anteriores a la 61.
