CVE-2011-1775 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.29% chance of exploitation in the next 30 days.
