tag_insight = "USN-1008-1 fixed vulnerabilities in libvirt. The upstream fixes for
  CVE-2010-2238 changed the behavior of libvirt such that the domain
  XML could not specify 'host_device' as the qemu sub-type. While libvirt
  0.8.3 and later will longer support specifying this sub-type, this
  update restores the old behavior on Ubuntu 10.04 LTS.

  We apologize for the inconvenience.
  
  Original advisory details:
  
  It was discovered that libvirt would probe disk backing stores without
  consulting the defined format for the disk. A privileged attacker in the
  guest could exploit this to read arbitrary files on the host. This issue
  only affected Ubuntu 10.04 LTS. By default, guests are confined by an
  AppArmor profile which provided partial protection against this flaw.
  (CVE-2010-2237, CVE-2010-2238)
  
  It was discovered that libvirt would create new VMs without setting a
  backing store format. A privileged attacker in the guest could exploit this
  to read arbitrary files on the host. This issue did not affect Ubuntu 8.04
  LTS. In Ubuntu 9.10 and later guests are confined by an AppArmor profile
  which provided partial protection against this flaw. (CVE-2010-2239)
  
  Jeremy Nickurak discovered that libvirt created iptables rules with too
  lenient mappings of source ports. A privileged attacker in the guest could
  bypass intended restrictions to access privileged resources on the host.
