Official description
A NULL pointer dereference in GPAC MP4Box: when parsing certain truncated MP4 files, an unknown/invalid stsd entry can result in missing descriptor fields (e.g., codec/mime/profile strings). gf_media_map_esd then calls strlen() on a NULL pointer, triggering a crash (ASan SEGV).
