The version of MySQL running on the remote host is 5.6.x prior to 5.6.20. It is, therefore, affected by a use-after-free error in the mysql_prune_stmt_list() function in client.c, that allows an authenticated, remote attacker to cause a denial of service condition.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
