  An insufficient input validation flaw was discovered in the VNC client
  application, vncviewer. If an attacker could convince a victim to connect
  to a malicious VNC server, or when an attacker was able to connect to
  vncviewer running in the 'listen' mode, the attacker could cause the
  victim's vncviewer to crash or, possibly, execute arbitrary code.
  (CVE-2008-4770)

  Users of vncviewer should upgrade to these updated packages, which contain
  a backported patch to resolve this issue. For the update to take effect,
  all running instances of vncviewer must be restarted after the update is
  installed.");
