CVE-2021-30022

Exploit
There is a integer overflow in media_tools/av_parsers.c in the gf_avc_read_pps_bs_internal in GPAC from 0.5.2 to 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.

CWE-190 Integer Overflow or Wraparound

The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
