Descriptions

Embedthis GoAhead before 5.0.1 mishandles redirected HTTP requests with a large Host header. The GoAhead WebsRedirect uses a static host buffer that has a limited length and can overflow. This can cause a copy of the Host header to fail, leaving that buffer uninitialized, which may leak uninitialized data in a response.

Incruste GoAhead versiones anteriores a 5.0.1, maneja inapropiadamente las peticiones HTTP redireccionadas con un encabezado Host grande. GoAhead WebsRedirect utiliza un búfer de host estático que posee una longitud limitada y puede desbordarse. Esto puede causar un fallo de la copia del encabezado del Host, dejando ese búfer no inicializado, lo que puede filtrar datos sin inicializar en una respuesta.
