  - A remote code execution vulnerability exists due to

    denial of service condition or the execution of
    arbitrary code on the host OS. (CVE-2012-3288)

  - A denial of service vulnerability exists due to
    improper handling of traffic originating from mobile

    crash the guest OS. (CVE-2012-3289)");
