Language: Java
Label: vulnerable
CWE: CWE-400 \u2014 Uncontrolled Resource Consumption
The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources.

Code:
	public static void copy(InputStream in, OutputStream out, int bufferSize)
			throws IOException
	{
		byte[] b = new byte[bufferSize];
		int read;

		while ((read = in.read(b)) != -1)
		{
			out.write(b, 0, read);
		}
	}
