Scientific Linux Security Update : tigervnc on SL6.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

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.
