A critical vulnerability in `lib/server.c` allowed attackers to trigger out-of-bounds memory reads when copying credentials via unsafe `memcpy()` calls. By replacing `memcpy()` with bounds-safe `strlcpy()`, the fix ensures credentials are safely stored without buffer overruns or null-termination issues.
A critical memory safety vulnerability was discovered and patched in `src/cache.c`, where an unchecked `memcpy` operation could be exploited via attacker-controlled network responses to cause out-of-bounds memory reads and writes. The root cause — a silent unsigned integer underflow — is a classic but devastatingly dangerous pattern that can lead to remote code execution, data corruption, or application crashes. Understanding this vulnerability is essential for any developer working with low-lev
