CVE-2017-14059

In FFmpeg 3.3.3, a DoS in cine_read_header() due to lack of an EOF check
might cause huge CPU and memory consumption. When a crafted CINE file,
which claims a large “duration” field in the header but does not contain
sufficient backing data, is provided, the image-offset parsing loop would
consume huge CPU and memory resources, since there is no EOF check inside
the loop.
