Here are the details from the Slackware 14.1 ChangeLog:
+--------------------------+
patches/packages/samba-4.1.16-i486-1_slack14.1.txz: Upgraded.
 This update is a security release in order to address CVE-2014-8143
 (Elevation of privilege to Active Directory Domain Controller).
 Samba's AD DC allows the administrator to delegate creation of user or
 computer accounts to specific users or groups. However, all released
 versions of Samba's AD DC did not implement the additional required
 check on the UF_SERVER_TRUST_ACCOUNT bit in the userAccountControl
 attributes. Most Samba deployments are not of the AD Domain Controller,
 but are of the classic domain controller, the file server or print server.
 Only the Active Directory Domain Controller is affected by this issue.
 Additionally, most sites running the AD Domain Controller do not configure
 delegation for the creation of user or computer accounts, and so are not
 vulnerable to this issue, as no writes are permitted to the
 userAccountControl attribute, no matter what the value.
