buffer overflows (CWE-120, CWE-20). Specify a limit to %s, or use a
different input function. If the scanf format is influenceable by an
attacker, it's exploitable.

Statically-sized arrays can be improperly restricted, leading to potential
overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
functions that limit length, or ensure that the size is larger than the
