Descriptions
A flaw was found in the copying tool `nbdcopy` of libnbd. When performing multi-threaded copies using asynchronous nbd calls, nbdcopy was blindly treating the completion of an asynchronous command as successful, rather than checking the *error parameter. This could result in the silent creation of a corrupted destination image.
Se ha encontrado un fallo en la herramienta de copia "nbdcopy" de libnbd. Cuando eran llevado a cabo copias multihilo usando llamadas asíncronas a nbd, nbdcopy trataba ciegamente la finalización de un comando asíncrono como exitosa, en lugar de comprobar el parámetro *error. Esto podía resultar en la creación silenciosa de una imagen de destino corrupta
