Perform bounds checking, use functions that limit length, or ensure that the size is larger than the maximum possible length. char exponent_buf[10]; data/mlgmp-20021123/mlgmp_f.c:315:3: [2] (buffer) sprintf: Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or vsnprintf. Risk is low because the source has a constant maximum length. sprintf(exponent_buf, "@%08lx", (exponent & 0xFFFFFFFFUL)); data/mlgmp-20021123/mlgmp_fr.c:421:3: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).
