remote attacker could exploit this to cause a denial of service via
application crash. (CVE-2011-1486)

Eric Blake discovered that libvirt had an off-by-one error which could
be used to reopen disk probing and bypass the fix for CVE-2010-2238. A
privileged attacker in the guest could exploit this to read arbitrary files
on the host. This issue only affected Ubuntu 11.04. By default, guests are
confined by an AppArmor profile which provided partial protection against
this flaw. (CVE-2011-2178)");
