Does this matter?
Lower severity and a low EPSS score (1.07%). Track it; it rarely justifies an emergency change on its own.
Description
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.
