There is a integer overflow in media_tools/av_parsers.c in the hevc_parse_slice_segment function in GPAC from v0.9.0-preview to 1.0.1 which results in a crash.
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.
