Buffer Overflow vulnerability exists in FFmpeg 4.2 in filter_vertically_8 at libavfilter/vf_avgblur.c, which could cause a remote Denial of Service.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
