New bind packages are available for Slackware 14.0, 14.1, 14.2, and -current to
fix a denial-of-service security issue.

Here are the details from the Slackware 14.2 ChangeLog:

patches/packages/bind-9.11.8-i586-1_slack14.2.txz: Upgraded.
Fixed a race condition in dns_dispatch_getnext() that could cause an
assertion failure if a significant number of incoming packets were rejected.
For more information, see:
https://kb.isc.org/docs/cve-2019-6471
https://vulners.com/cve/CVE-2019-6471
(* Security fix *)
