If length is >= 0x80000000 (2 GB), length * 2 wraps around to a small value, calloc allocates a too small buffer, then the loop writes length * 2 bytes into it causing a heap buffer overflow. Fix this by using a size_t for size calculation, and also checking the length before multiplication (needed on 32 bit platforms).
