[FFmpeg-devel] [PATCH] fix for bfi buffer overread (roundup issue 2497)

[Daniel Kang]

When the input resolution is too large, the bfi decoder overreads the
data buffer. The patch attached adds a sanity check to prevent this.
ffmpeg will still fail in decoding this with an assertion error (the
video data itself is invalid with the sample), but it does not buffer
overread.

The roundup issue is 2497.
