The remote FreeBSD host is missing one or more security-related updates.


Alan Coopersmith reports :

Pedro Ribeiro (pedrib at reported an issue to the X.Org security team 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.
