Overview
FFmpeg is a FFmpeg static library ruby binding that is compiled for iOS and CocoaPods.
Affected versions of this package are vulnerable to Heap-based Buffer Overflow. The size calculation in build_open_gop_key_points() goes through all entries in the loop and adds sc->ctts_data[i].count to sc->sample_offsets_count. This can lead to an integer overflow resulting in a small allocation with `av_calloc().
