This fixes a security issue, which can be exploited by malicious people to disclose potentially sensitive information. The security issue is caused due to the vncviewer not properly validating the X.509 certificate of a TLS VNC server before providing client credentials. This can be exploited to e.g. disclose logon credentials of a user by tricking the user into connecting to a malicious server. SOLUTION: Updated packages are available via Red Hat Network.
