  script_tag(name:"insight", value:"The gtk-vnc packages provide a VNC viewer
  widget for GTK. The gtk-vnc widget is built by using co-routines, which allows
  the widget to be completely asynchronous while remaining single-threaded. The
  following packages have been upgraded to a later upstream version: gtk-vnc
  (0.7.0). (BZ#1416783) Security Fix(es): * It was found that gtk-vnc lacked
  proper bounds checking while processing messages using RRE, hextile, or copyrect
  encodings. A remote malicious VNC server could use this flaw to crash VNC
  viewers which are based on the gtk-vnc library. (CVE-2017-5884) * An integer
  overflow flaw was found in gtk-vnc. A remote malicious VNC server could use this
  flaw to crash VNC viewers which are based on the gtk-vnc library.
  (CVE-2017-5885) 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.");
