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 (0.7.0). (BZ#1416783)
Security Fix(es):
-
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. (CVE-2017-5884)
-
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. (CVE-2017-5885)
