Samba 3.x and 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3
supports connections that are encrypted but unsigned, which allows
man-in-the-middle attackers to conduct encrypted-to-unencrypted downgrade
attacks by modifying the client-server data stream, related to clidfs.c,
libsmb_server.c, and smbXcli_base.c.
