CVE-2018-13300

In FFmpeg 3.2 and 4.0.1, an improper argument (AVCodecParameters) passed to the avprivrequestsample function in the handle_eac3 function in libavformat/movenc.c may trigger an out-of-array read while converting a crafted AVI file to MPEG4, leading to a denial of service and possibly an information disclosure.
