Security vulnerabilities and automated fixes for game development issues

A critical stack-based buffer overflow was discovered in `src/debugger.cpp` at line 387, where `strcpy` copied user-entered debugger commands into a fixed-size stack buffer (`prevCommandBuffer`) without any length validation. An attacker could craft an oversized command string to overflow the buffer, overwrite the return address, and achieve arbitrary code execution. The fix replaces `strcpy` with bounded `strncpy` and explicit null-termination.
A critical out-of-bounds heap read vulnerability was discovered in the Effekseer GLTF resource loader, where a `memcpy` operation copied data from a buffer without first verifying the source contained enough bytes. An attacker could craft a malicious GLTF file with truncated buffer data to crash the application or leak sensitive heap memory contents. The fix adds a simple but essential bounds check before the copy operation, ensuring the source buffer always contains at least as many bytes as th
A critical buffer overflow vulnerability was discovered and patched in a C-based game engine, where unbounded `strcpy()` calls in `src/game.c` and `src/anime.c` could allow attackers to overwrite adjacent memory and hijack program control flow. This type of vulnerability has been responsible for some of the most devastating exploits in software history and remains a top concern in systems-level C programming. The fix eliminates the unsafe string copy operations, closing a path that could have en
