CVE-2017-14223

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.
