Hi, is there any chance, that somebody can hack in to the Linux machine through VirtualBox? Let say, that I am running Linux 1, I've installed VBox and on VBox another Linux 2 distro. Is there any chance, that during using Linux 2 via VBox, Linux 1 host system can be hacked? If so, how?

I'm asking, because I'm planning to install VBox and test some others systems etc.

Thanks.
