"Fixes the following security issue :

  - an authenticated X client can cause an X server to use
    memory after it was freed, potentially leading to crash
    and/or memory corruption. (CVE-2013-4396, bnc#843652)
    and the following bug was fixed too :

  - rfbAuthReenable is accessing rfbClient structure that
    was in most cases already freed. It actually needs only
    ScreenPtr, so pass it directly. (bnc#816813)"
