CVE-2019-20630
It contains a heap-based buffer over-read in BS_ReadByte (called from gf_bs_read_bit) in utils/bitstream.c that can cause a denial of service via a crafted MP4 file.
Does this matter?
Lower severity and a low EPSS score (0.93%). Track it; it rarely justifies an emergency change on its own.
