The HandleRFBServerMessage function in libvncclient/rfbproto.c in
LibVNCServer 0.9.9 and earlier does not check certain malloc return values,
which allows remote VNC servers to cause a denial of service (application
crash) or possibly execute arbitrary code by specifying a large screen size
in a (1) FramebufferUpdate, (2) ResizeFrameBuffer, or (3)
PalmVNCReSizeFrameBuffer message.
