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

The MITRE CVE dictionary describes this issue as:

The CSecurityTLS::processMsg function in common/rfb/CSecurityTLS.cxx in the vncviewer component in TigerVNC 1.1beta1 does not properly verify the server's X.509 certificate, which allows man-in-the-middle attackers to spoof a TLS VNC server via an arbitrary certificate.
