A bind security update has been released for Slackware Linux 14.0, 14.1, 14.2, and -current.

bind (SSA:2021-300-01)

New bind 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/bind-9.11.36-i586-1_slack14.2.txz: Upgraded.
This update fixes bugs and the following security issue:
The "lame-ttl" option is now forcibly set to 0. This effectively disables the lame server cache, as it could previously be abused by an attacker to significantly degrade resolver performance.
For more information, see: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-25219 (* Security fix *)
