NVD Description

Note: Versions mentioned in the description apply only to the upstream gpac package and not the gpac package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

An issue was discovered in libgpac.a in GPAC before 0.8.0, as demonstrated by MP4Box. 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.
