Server memory information leak via SMB1.
This is an SMB1-only vulnerability. Since Samba release 4.11.0 SMB1 has been disabled by default. We do not recommend enabling SMB1 server support. For Samba versions prior to 4.11.0 please disable SMB1 by adding `server min protocol = SMB2_02` to the [global] section of your smb.conf and restarting smbd.
