Action Type Old Value New Value Changed Description 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. gtk-vnc before 0.7.0 does not properly check boundaries of subrectangle-containing tiles, which allows remote servers to execute arbitrary code via the src x, y coordinates in a crafted (1) rre, (2) hextile, or (3) copyrect tile.
