3. 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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

702470 - CVE-2011-1775 tigervnc: vncviewer can send password to server without proper validation of the X.509 certificate
