"Security Fix(es) :

  - A memory allocation flaw, leading to a heap-based buffer
    overflow, was found in spice's smartcard interaction,
    which runs under the QEMU-KVM context on the host. A
    user connecting to a guest VM using spice could
    potentially use this flaw to crash the QEMU-KVM process
    or execute arbitrary code with the privileges of the
    host's QEMU-KVM process. (CVE-2016-0749)

  - A memory access flaw was found in the way spice handled
    certain guests using crafted primary surface parameters.
    A user in a guest could use this flaw to read from and
    write to arbitrary memory locations on the host.
    (CVE-2016-2150)"
