Is Spectrum vulnerable to Samba Vulnerability CVE-2018-1057 and CVE-2018-1050?
1, Authenticated users can change other users' password (CVE-2018-1057)
On a Samba 4 AD DC the LDAP server in all versions of Samba from 4.0.0 onwards incorrectly validates permissions to modify passwords over LDAP allowing authenticated users to change any other users' passwords, including administrative users and privileged service accounts (eg Domain Controllers). The LDAP server incorrectly validates certain LDAP password modifications against the "Change Password" privilege, but then performs a password reset operation.
2. Denial of Service Attack on external print server (CVE-2018-1050)
All versions of Samba from 4.0.0 onwards are vulnerable to a denial of service attack when the RPC spoolss service is configured to be run as an external daemon. Missing input sanitization checks on some of the input parameters to spoolss RPC calls could cause the print spooler service to crash.
