  script_tag(name:"insight", value:"Kernel-based Virtual Machine (KVM) is a full
  virtualization solution for Linux on a variety of architectures. The qemu-kvm
  package provides the user-space component for running virtual machines that use
  KVM. Security Fix(es): * An out-of-bounds r/w access issue was found in QEMU's
  Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while
  copying VGA data via various bitblt functions. A privileged user inside a guest
  could use this flaw to crash the QEMU process or, potentially, execute arbitrary
  code on the host with privileges of the QEMU process. (CVE-2017-7980) * An
  out-of-bounds access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator
  support. The vulnerability could occur while copying VGA data using bitblt
  functions (for example, cirrus_bitblt_rop_fwd_transp_). A privileged user inside
  a guest could use this flaw to crash the QEMU process, resulting in denial of
  service. (CVE-2017-7718) Red Hat would like to thank Jiangxin (PSIRT Huawei Inc)
  and Li Qiang (Qihoo 360 Gear Team) for reporting CVE-2017-7980 and Jiangxin
  (PSIRT Huawei Inc) for reporting CVE-2017-7718. Bug Fix(es): * Previously, guest
  virtual machines in some cases became unresponsive when the 'pty' back end of a
  serial device performed an irregular I/O communication. This update improves the
  handling of serial I/O on guests, which prevents the described problem from
  occurring. (BZ#1452332)");
