Descriptions

In libavformat/asfdec_f.c in FFmpeg 3.3.3, a DoS in asf_build_simple_index() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted ASF file, which claims a large "ict" field in the header but does not contain sufficient backing data, is provided, the for loop would consume huge CPU and memory resources, since there is no EOF check inside the loop.

En libavformat/asfdec_f.c en FFmpeg 3.3.3, una denegación de servicio en asf_build_simple_index() debido a una falta de comprobación EOE (End of File) podría provocar un gran consumo de CPU. Cuando se proporciona un archivo ASF manipulado, que reclama un gran campo "ict" en el encabezado pero que no contiene datos de respaldo suficientes, el bucle for consumiría una gran cantidad de recursos de CPU y de memoria, ya que no existe una comprobación EOF dentro del bucle.
