CWE: CWE-190 \u2014 Integer Overflow or Wraparound
The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control.

Code:
    public static byte[] compress(long[] input)
            throws IOException
    {
        int byteSize = input.length * 8;
        if (byteSize < input.length) {
            throw new SnappyError(SnappyErrorCode.TOO_LARGE_INPUT, "input array size is too large: " + input.length);
        }
        return rawCompress(input, byteSize); // long uses 8 bytes
    }
