The rfbProcessClientNormalMessage function in libvncserver/rfbserver.c in
LibVNCServer 0.9.9 and earlier does not properly handle attempts to send a
large amount of ClientCutText data, which allows remote attackers to cause
a denial of service (memory consumption or daemon crash) via a crafted
message that is processed by using a single unchecked malloc.
