Descriptions
An issue was discovered in res_http_websocket.c in Asterisk 15.x through 15.2.1. If the HTTP server is enabled (default is disabled), WebSocket payloads of size 0 are mishandled (with a busy loop).
Se ha descubierto un problema en res_http_websocket.c en Asterisk hasta la versión 15.2.1. Si el servidor HTTP está habilitado (está deshabilitado por defecto), las cargas útiles de WebSocket de tamaño 0 se gestionan de forma incorrecta (con un bucle ocupado).
When reading a websocket, the length was not being checked. If a payload of length 0 was read, it would result in a busy loop that waited for the underlying connection to close.
