Description ybuenos 2022-12-11 13:11:35 UTC 
Integer overflow in realloc and memcpy calls in core_anal_graph_label. In the process of concatenating source lines based on DWARF data, the resulting size (32bit signed int) can overflow. The sizes of the realloc and memcpy calls differ, and potentially can lead to writes in an unintended location.
