Updated gtk-vnc packages fix security vulnerability

It was found that gtk-vnc code does not properly check boundaries of subrectangle-containing tiles. A malicious server can use this to overwrite parts of the client memory (CVE-2017-5884).

In addition, the vnc_connection_server_message() and vnc_color_map_set() functions do not check for integer overflow properly, leading to a malicious server being able to overwrite parts of the client memory (CVE-2017-5885).
