Descriptions

In libavformat/mxfdec.c in FFmpeg 3.3.3 -> 2.4, a DoS in mxf_read_index_entry_array() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted MXF file, which claims a large "nb_index_entries" field in the header but does not contain sufficient backing data, is provided, the loop would consume huge CPU resources, since there is no EOF check inside the loop. Moreover, this big loop can be invoked multiple times if there is more than one applicable data segment in the crafted MXF file.

En libavformat/mxfdec.c en FFmpeg versión 3.3.3 mayor a 2.4, en DoS una denegación de servicio en mxf_read_index_entry_array() por una falta de chequeos EOF (End of File) podría provocar un enorme consumo de recursos de la CPU. Cuando se proporciona un archivo MXF manipulado que pide un campo "nb_index_entries" grande en la cabecera pero no contiene suficientes datos de respaldo, el bucle consumiría una gran cantidad de recursos de CPU, ya que el bucle no contiene ningún chequeo EOF. Además, este gran bucle se invocaría en múltiples ocasiones si existe más de un segmento de datos aplicable en el archivo MXF manipulado
