Descriptions
When reading binary Ion data through Amazon.IonDotnet using the RawBinaryReader class, Amazon.IonDotnet does not check the number of bytes read from the underlying stream while deserializing the binary format. If the Ion data is malformed or truncated, this triggers an infinite loop condition that could potentially result in a denial of service. Users should upgrade to Amazon.IonDotnet version 1.3.1 and ensure any forked or derivative code is patched to incorporate the new fixes.
Al leer datos binarios de Ion a través de Amazon.IonDotnet con la clase RawBinaryReader, Amazon.IonDotnet no comprueba el número de bytes leídos del flujo subyacente al deserializar el formato binario. Si los datos de Ion están malformados o truncados, se activa un bucle infinito que podría resultar en una denegación de servicio. Los usuarios deben actualizar a la versión 1.3.1 de Amazon.IonDotnet y asegurarse de que cualquier código bifurcado o derivado esté parcheado para incorporar las nuevas correcciones.
