The gtk-vnc packages provide a VNC viewer widget for GTK. The gtk-vnc widget is built by using co-routines, which allows the widget to be completely asynchronous while remaining single-threaded. The following packages have been upgraded to a later upstream version: gtk-vnc . Security Fix: * It was found that gtk-vnc lacked proper bounds checking while processing messages using RRE, hextile, or copyrect encodings. A remote malicious VNC server could use this flaw to crash VNC viewers which are based on the gtk-vnc library. * An integer overflow flaw was found in gtk-vnc. A remote malicious VNC server could use this flaw to crash VNC viewers which are based on the gtk-vnc library.
