CVE-2011-1775

TigerVNC 1.1beta1 - Man-in-the-Middle

Title source: llm
STIX 2.1

Description

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.
