Follow the instructions at https://www.virtualbox.org/wiki/Linux_Downloads that concern "Debian-based distributions." You'll need to add the "PPA" to your system as described there. Then after "sudo apt-get update" followed by "sudo apt-get install virtualbox-4.1" you'll have the latest release from Oracle.

You might want to run "sudo apt-get purge virtualbox-*" first to remove any existing packages.

Don't forget to install the Guest Additions as well; again the virtualbox.org website will explain how to do this.
