libvirt is vulnerable to information disclosure. It was found that libvirt created insecure iptables rules on the host when a guest system was configured for IP masquerading, allowing the guest to use privileged ports on the host when accessing network resources. A privileged guest user could use this flaw to access network resources that would otherwise not be accessible to the guest.
