"xorg-x11-server was updated to fix the following security issue :

  - Fixed a security issue in which 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)

A non-security issues was also fixed :

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