Here are the details from the Slackware 14.1 ChangeLog:
+--------------------------+
patches/packages/samba-4.1.6-i486-1_slack14.1.txz: Upgraded.
 This update fixes two security issues:
 CVE-2013-4496:
 Samba versions 3.4.0 and above allow the administrator to implement
 locking out Samba accounts after a number of bad password attempts.
 However, all released versions of Samba did not implement this check for
 password changes, such as are available over multiple SAMR and RAP
 interfaces, allowing password guessing attacks.
 CVE-2013-6442:
 Samba versions 4.0.0 and above have a flaw in the smbcacls command. If
 smbcacls is used with the '-C<pipe>--chown name' or '-G<pipe>--chgrp name'
 command options it will remove the existing ACL on the object being
 modified, leaving the file or directory unprotected.
