Descriptions

In libavformat/rl2.c in FFmpeg 3.3.3, a DoS in rl2_read_header() due to lack of an EOF (End of File) check might cause huge CPU and memory consumption. When a crafted RL2 file, which claims a large "frame_count" field in the header but does not contain sufficient backing data, is provided, the loops (for offset and size tables) would consume huge CPU and memory resources, since there is no EOF check inside these loops.

En libavformat/rl2.c in FFmpeg 3.3.3, se podría realizar un ataque de denegación de servicio en rl2_read_header() al no haber un chequeo EOF (End Of File) que podría provocar acabar en un gran consumo de CPU y de memoria. Cuando se envía un archivo RL2 manipulado que reclama un campo "frame_count" grande en la cabecera pero que no contiene suficientes datos de respaldo, los bucles (para las tablas offset y size) consumirían una gran cantidad de recursos de CPU y de memoria, ya que no hay ningún chequeo EOF en los bucles.
