In GPAC 0.7.1 and earlier, gf_text_get_utf8_line in media_tools/text_import.c in libgpac_static.a allows an out-of-bounds write because a certain -1 return value is mishandled.
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.
