"The following bugs have been fixed :

  - By causing a hot-unplug of the pci-isa bridge from
    within guests the qemu process could access already
    freed memory. A privileged user inside the guest could
    exploit that to crash the guest instance or potentially
    execute arbitrary code on the host. (CVE-2011-1751)

  - The virtio-blk driver did not properly validate read and
    write request. A privileged user inside the guest could
    exploit that to cause a heap corruption and crash the
    guest instance or potentially execute arbitrary code on
    the host. (CVE-2011-1750)"
