New samba packages are available for Slackware 14.0, 14.1, 14.2, and -current
to fix security issues.

Here are the details from the Slackware 14.2 ChangeLog:

patches/packages/samba-4.6.16-i586-1_slack14.2.txz: Upgraded.
This is a security release in order to address the following defects:
Insufficient input validation on client directory listing in libsmbclient.
A malicious server could return a directory entry that could corrupt
libsmbclient memory.
Confidential attribute disclosure from the AD LDAP server.
Missing access control checks allow discovery of confidential attribute
values via authenticated LDAP search expressions.
For more information, see:
