CWE: CWE-502 \u2014 Deserialization of Untrusted Data
The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid.

Code:
	public void writeData(LPDataOutput output) throws IOException {
		super.writeData(output);
		for (int i = 0; i < renderCache.length; i++) {
			bits.set(i, renderCache[i] != null);
		}
		output.writeBitSet(bits);
		for (FluidStack aRenderCache : renderCache) {
			if (aRenderCache != null) {
				output.writeInt(FluidRegistry.getFluidID(aRenderCache.getFluid()));
				output.writeInt(aRenderCache.amount);
				output.writeNBTTagCompound(aRenderCache.tag);
			}
		}
	}
