CVE-2018-1139 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:14.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream samba package and not the samba package as distributed by Ubuntu.
A flaw was found in the way samba before 4.7.9 and 4.8.4 allowed the use of weak NTLMv1 authentication even when NTLMv1 was explicitly disabled. A man-in-the-middle attacker could use this flaw to read the credential and other details passed between the samba server and client.
