CVE-2021-30022: Integer Overflow
First published: Mon Apr 19 2021(Updated: )
There is a integer overflow in media_tools/av_parsers.c in the gf_avc_read_pps_bs_internal in GPAC 1.0.1. pps_id may be a negative number, so it will not return. However, avc->pps only has 255 unit, so there is an overflow, which results a crash.
