[CVE-2015-5370] Errors in Samba DCE-RPC code can lead to denial of service
(crashes and high cpu consumption) and man in the middle attacks.
[CVE-2016-2110] The feature negotiation of NTLMSSP is not downgrade protected.
A man in the middle is able to clear even required flags, especially
NTLMSSP_NEGOTIATE_SIGN and NTLMSSP_NEGOTIATE_SEAL.
[CVE-2016-2111] When Samba is configured as Domain Controller it allows remote
attackers to spoof the computer name of a secure channel's endpoints, and obtain
sensitive session information, by running a crafted application and leveraging
the ability to sniff network traffic.
[CVE-2016-2112] A man in the middle is able to downgrade LDAP connections
to no integrity protection.
[CVE-2016-2113] Man in the middle attacks are possible for client triggered LDAP
connections (with ldaps://) and ncacn_http connections (with https://).
[CVE-2016-2114] Due to a bug Samba doesn't enforce required smb signing, even if explicitly configured.
[CVE-2016-2115] The protection of DCERPC communication over ncacn_np (which is
the default for most the file server related protocols) is inherited from the underlying SMB connection.
[CVE-2016-2118] a.k.a. BADLOCK. A man in the middle can intercept any DCERPC traffic
between a client and a server in order to impersonate the client and get the same privileges
as the authenticated user account. This is most problematic against active directory domain controllers.
