Descriptions
A heap-based buffer overflow was discovered in bluetoothd in BlueZ through 5.48. There isn't any check on whether there is enough space in the destination buffer. The function simply appends all data passed to it. The values of all attributes that are requested are appended to the output buffer. There are no size checks whatsoever, resulting in a simple heap overflow if one can craft a request where the response is large enough to overflow the preallocated buffer. This issue exists in service_attr_req gets called by process_request (in sdpd-request.c), which also allocates the response buffer.
Se ha detectado un desbordamiento del búfer en la región heap de la memoria en bluetoothd en BlueZ versiones hasta 5.48. No presenta ninguna comprobación sobre si presenta suficiente espacio en el buffer de destino. La función simplemente añade todos los datos que son pasados. Los valores de todos los atributos solicitados son añadidos al búfer de salida. No se presenta ningún tipo de comprobación de tamaño, resultando en un simple desbordamiento de la pila si es posible diseñar una petición en la que la respuesta sea lo suficientemente grande como para desbordar el búfer preasignado. Este problema se presenta cuando service_attr_req es llamado por process_request (en el archivo sdpd-request.c), que también asigna el buffer de respuesta
