  script_tag(name:"insight", value:"Virtual Network Computing (VNC) is a remote display system which allows you
  to view a computer's desktop environment not only on the machine where it
  is running, but from anywhere on the Internet and from a wide variety of
  machine architectures. TigerVNC is a suite of VNC servers and clients.

  It was discovered that vncviewer could prompt for and send authentication
  credentials to a remote server without first properly validating the
  server's X.509 certificate. As vncviewer did not indicate that the
  certificate was bad or missing, a man-in-the-middle attacker could use this
  flaw to trick a vncviewer client into connecting to a spoofed VNC server,
  allowing the attacker to obtain the client's credentials. (CVE-2011-1775)

  All tigervnc users should upgrade to these updated packages, which contain
  a backported patch to correct this issue.");
