Description

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