New bind packages are available for Slackware 15.0 and -current to fix
a security issue.

Here are the details from the Slackware 15.0 ChangeLog:

patches/packages/bind-9.16.42-i586-1_slack15.0.txz: Upgraded.
This update fixes a security issue:
Exceeding the recursive-clients quota may cause named to terminate
unexpectedly when stale-answer-client-timeout is set to 0.
For more information, see:
https://kb.isc.org/docs/cve-2023-2911
https://vulners.com/cve/CVE-2023-2911
(* Security fix *)
