Descripción |
|
|
Se ha descubierto una vulnerabilidad en Fetchmail versión 6.2.5.2 y anteriores. La vulnerabilidad reside en que la utilidad "fetchmailconf" escribe ficheros de configuración que tienen durante un corto periodo de tiempo permisos de lectura para cualquier usuario. Un atacante local podría obtener contraseñas mediante la lectura de los ficheros de configuración durante la ventana de tiempo en que Fetchmailconf asigna los permisos adecuados. |
