samba -- multiple vulnerabilities

The samba project reports:

Samba releases 4.7.0 to 4.8.3 (inclusive) contain an error which
allows authentication using NTLMv1 over an SMB1 transport (either
directory or via NETLOGON SamLogon calls from a member server), even
when NTLMv1 is explicitly disabled on the server.

Missing input sanitization checks on some of the input parameters to
LDB database layer cause the LDAP server and DNS server to crash when
following a NULL pointer.

Samba releases 3.2.0 to 4.8.3 (inclusive) contain an error in
libsmbclient that could allow a malicious server to overwrite
client heap memory by returning an extra long filename in a directory
listing.

Missing database output checks on the returned directory attributes
from the LDB database layer cause the DsCrackNames call in the DRSUAPI
server to crash when following a NULL pointer.

All versions of the Samba Active Directory LDAP server from 4.0.0
onwards are vulnerable to the disclosure of confidential attribute
values, both of attributes where the schema SEARCH_FLAG_CONFIDENTIAL
(0x80) searchFlags bit and where an explicit Access Control Entry has
been specified on the ntSecurityDescriptor.
