How to fix?

Upgrade Debian:unstable libvirt to version 0.8.3-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libvirt package and not the libvirt package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

Red Hat libvirt 0.2.0 through 0.8.2 creates iptables rules with improper mappings of privileged source ports, which allows guest OS users to bypass intended access restrictions by leveraging IP address and source-port values, as demonstrated by copying and deleting an NFS directory tree.
