UBUNTU-CVE-2016-2118

The MS-SAMR and MS-LSAD protocol implementations in Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 mishandle DCERPC connections, which allows man-in-the-middle attackers to perform protocol-downgrade attacks and impersonate users by modifying the client-server data...

Man in the middle attacks possible with NTLMSSP

Description There are several man in the middle attacks possible with NTLMSSP authentication. E.g. NTLMSSPNEGOTIATESIGN and NTLMSSPNEGOTIATESEAL can be cleared by a man in the middle. This was by protocol design in earlier Windows versions. Windows Server 2003 RTM and Vista RTM introduced a way t...
