Upstream information
Description
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 stream, aka "BADLOCK."Upstream Security Advisories:

Note from the SUSE Security Team
This security feature that is affected by this bug was added in the Samba 3.6 series, so only Samba 3.6 and later were affected by this problem.
