Descriptions

Discourse is an open source platform for community discussion. A malicious request can cause production log files to quickly fill up and thus result in the server running out of disk space. This problem has been patched in the 3.1.1 stable and 3.2.0.beta2 versions of Discourse. It is possible to temporarily work around this problem by reducing the `client_max_body_size nginx directive`. `client_max_body_size` will limit the size of uploads that can be uploaded directly to the server.

Discourse es una plataforma de código abierto para el debate comunitario. Una solicitud maliciosa puede hacer que los archivos de registro de producción se llenen rápidamente y, por lo tanto, que el servidor se quede sin espacio en disco. Este problema se ha solucionado en las versiones 3.1.1 stable y 3.2.0.beta2 de Discourse. Es posible workaround temporalmente en este problema reduciendo "client_max_body_size nginx directive". `client_max_body_size` limitará el tamaño de las cargas que se pueden cargar directamente al servidor.
