The hevc_write_frame function in libbpg.c in libbpg 0.9.7 allows remote attackers to cause a denial of service (integer underflow and application crash) or possibly have unspecified other impact via a crafted BPG file, related to improper interaction with copy_CTB_to_hv in hevc_filter.c in libavcodec in FFmpeg and sao_filter_CTB in hevc_filter.c in libavcodec in FFmpeg.
The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
