Vulnerability CVE-2016-2114 - CERT Civis.Net

Vulnerability Name:

CVE-2016-2114 (CCN-111941)

Assigned:

2016-04-12

Published:

2016-04-12

Updated:

2016-12-31

Summary:

The SMB1 protocol implementation in Samba 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 does not recognize the "server signing = mandatory" setting, which allows man-in-the-middle attackers to spoof SMB servers by modifying the client-server data stream.
