This issue only affected Ubuntu 18.04 LTS.\n(CVE-2018-10918)\n\nPhillip Kuhrt discovered that the Samba LDAP server incorrectly handled\ncertain confidential attribute values. A remote authenticated attacker\ncould possibly use this issue to obtain certain sensitive information.\n(CVE-2018-10919)\n\nVivek Das discovered that Samba incorrectly handled NTLMv1 being explicitly\ndisabled on the server.
