| 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."
