TLDR; horrendous security exploits uncovered in code written in known unsafe language.

The code is an utter shitshow, inviting disaster through seemingly normal use of the language. It contains a mess of malpractices that make any modern C++ or Rust developer cringe: goto, memcpy, naked pointers, type unsafe casts, raw loops, using malloc to allocate memory for input buffers.

Why do people continue to juggle chainsaws? I think it's fear of new things, fear of change. Old habits die hard.
