"The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2012-478:01 advisory.

    KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware.
    Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual
    machine has private virtualized hardware: a network card, disk, graphics adapter, etc.
    Security issues fixed with this release:
     CVE-2011-2527
     CVE-2011-4111
    No information available at the time of writing, see the CVE link below.
     CVE-2012-0029
    Heap-based buffer overflow in the process_tx_desc function in the e1000 emulation (hw/e1000.c) in qemu-kvm
    0.12, and possibly other versions, allows guest OS users to cause a denial of service (QEMU crash) and
    possibly execute arbitrary code via crafted legacy mode packets.
     No information available at the time of writing, see the CVE link below.
    Fixed bugs:
     qemu-kvm scsi option can be used along the device option. Previously, when set to off, it did not
    disable the scsi feature but just hid the feature bit, allowing for malicious users to ignore the feature
    bit and issue a request. This scsi=off option can be used to mitigate the virtualization aspect of
    CVE-2011-4127 before installing the kernel from <A
    HREF=http://www.asianux.com/tsn_hq/index.php?m=errata&a=detail&eid=2720&sType... AXSA:2012-228:02</A>. If
    it is already installed, you can skip changing the scsi option.Other wise run the guests by invoking
    /usr/libexec/qemu-kvm directly and use the -global virtio-blk-pci.scsi=off option to apply the
    mitigation.
    Enhancement:
     qemu-kvm is now built with full RELRO and PIE support.
