Overview

Affected versions of this package are vulnerable to Out-of-bounds Write. In the function gf_hevc_read_pps_bs_internal function in media_tools/av_parsers.c in GPAC 1.0.1 there is a loop, which with crafted file, pps->num_tile_columns may be larger than sizeof(pps->column_width), which results in a heap overflow in the loop.
