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

Here are the details from the Slackware 14.2 ChangeLog:

patches/packages/samba-4.4.12-i586-1_slack14.2.txz: Upgraded.
This update fixes a security issue:
All versions of Samba prior to 4.6.1, 4.5.7, 4.4.12 are vulnerable to
a malicious client using a symlink race to allow access to areas of
the server file system not exported under the share definition.
For more information, see:
https://vulners.com/cve/CVE-2017-2619
(* Security fix *)

Where to find the new packages:
