NVD Description

Note: Versions mentioned in the description apply only to the upstream samba4 package and not the samba4 package as distributed by Oracle. See How to fix? for Oracle:6 relevant fixed versions and status.

libcli/smb/smbXcli_base.c in Samba 4.x before 4.2.14, 4.3.x before 4.3.11, and 4.4.x before 4.4.5 allows man-in-the-middle attackers to bypass a client-signing protection mechanism, and consequently spoof SMB2 and SMB3 servers, via the (1) SMB2_SESSION_FLAG_IS_GUEST or (2) SMB2_SESSION_FLAG_IS_NULL flag.
