Virtual Network Computing (VNC) is a remote display system which
allows you to view a computer's 'desktop' environment not only on the

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.
