Attackers can supply a crafted PLY file that makes ply_read_list_property() call an out-of-bounds handler, crashing ASCII parsing or corrupting memory in binary parsing.","summary":"RPly, a C library for reading PLY 3D model files, does not validate an array index when parsing list properties in a file header.
