20 Release Notes for Samba 4.7.6
22 =============================
25 This is a security release in order to address the following defects:
27 o CVE-2018-1050 (Denial of Service Attack on external print server.)
28 o CVE-2018-1057 (Authenticated users can change other users' password.)
36 All versions of Samba from 4.0.0 onwards are vulnerable to a denial of
37 service attack when the RPC spoolss service is configured to be run as
38 an external daemon. Missing input sanitization checks on some of the
39 input parameters to spoolss RPC calls could cause the print spooler
42 There is no known vulnerability associated with this error, merely a
43 denial of service. If the RPC spoolss service is left by default as an
44 internal service, all a client can do is crash its own authenticated
48 On a Samba 4 AD DC the LDAP server in all versions of Samba from
49 4.0.0 onwards incorrectly validates permissions to modify passwords
50 over LDAP allowing authenticated users to change any other users'
51 passwords, including administrative users.
53 Possible workarounds are described at a dedicated page in the Samba wiki:
