emulator.

  - CVE-2014-3689
    The Advanced Threat Research team at Intel Security
    reported that guest provided parameter were
    insufficiently validated in rectangle functions in the
    vmware-vga driver. A privileged guest user could use
    this flaw to write into qemu address space on the host,
    potentially escalating their privileges to those of the
    qemu host process.

  - CVE-2014-7815
    James Spadaro of Cisco reported insufficiently sanitized
    bits_per_pixel from the client in the QEMU VNC display
    driver. An attacker having access to the guest's VNC
    console could use this flaw to crash the guest."
