GPAC through 0.7.1 has a Buffer Overflow in the gf_media_avc_read_sps function in media_tools/av_parsers.c, a different vulnerability than CVE-2018-1000100.

From the Ubuntu Security Team

It was discovered that the GPAC MP4Box utility incorrectly handled certain memory operations. If an user or automated system were tricked into opening a specially crafted MP4 file, a remote attacker could use this issue to cause MP4Box to crash, resulting in a denial of service, or possibly execute arbitrary code.
