  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 memory access issue was found in Quick
  Emulator (QEMU) in the VNC display driver. This flaw could occur while
  refreshing the VNC display surface area in the 'vnc_refresh_server_surface'. A
  user inside a guest could use this flaw to crash the QEMU process.
  (CVE-2017-2633) * An integer overflow flaw was found in Quick Emulator (QEMU) in
  the CCID Card device support. The flaw could occur while passing messages via
  command/response packets to and from the host. A privileged user inside a guest
  could use this flaw to crash the QEMU process. (CVE-2017-5898) * An information
  exposure flaw was found in Quick Emulator (QEMU) in Task Priority Register (TPR)
  optimizations for 32-bit Windows guests. The flaw could occur while accessing
  TPR. A privileged user inside a guest could use this issue to read portions of
  the host memory. (CVE-2016-4020) Red Hat would like to thank Li Qiang (360.cn
  Inc.) for reporting CVE-2017-5898 and Donghai Zdh (Alibaba Inc.) for reporting
  CVE-2016-4020. Additional Changes: For detailed information on changes in this
  release, see the Red Hat Enterprise Linux 7.4 Release Notes linked from the
  References section.");
