Synopsis :

The remote Samba server is affected by a remote code execution

Description :

According to its banner, the version of Samba running on the remote
host is 3.5.x prior to 3.5.22, 3.6.x prior to 3.6.25, 4.0.x prior to
4.0.25, or 4.1.x prior to 4.1.17. It is, therefore, affected by a
remote code execution vulnerability in the TALLOC_FREE() function of
'rpc_server/netlogon/srv_netlog_nt.c'. A remote attacker, using a
specially crafted sequence of packets followed by a subsequent
anonymous netlogon packet, can execute arbitrary code as the root

Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number.
