An authentication flaw was found in Samba. When Samba is configured to act as a Domain Controller, it allows remote attackers to spoof the computer name of a secure channel's endpoints. The attacker could exploit this flaw to obtain sensitive session information by running a crafted application and leveraging the ability to sniff network traffic. This flaw only affects Samba running as a classic primary domain controller, classic backup domain controller, or Active Directory domain controller. Note: This flaw is referred to as CVE-2015-0005 for Microsoft Windows Server.
