[slackware-security] bind (SSA:2023-025-01)

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

Here are the details from the Slackware 15.0 ChangeLog:
patches/packages/bind-9.16.37-i586-1_slack15.0.txz: Upgraded.
This update fixes bugs and the following security issues:
An UPDATE message flood could cause :iscman:`named` to exhaust all
available memory. This flaw was addressed by adding a new
:any:`update-quota` option that controls the maximum number of
outstanding DNS UPDATE messages that :iscman:`named` can hold in a
queue at any given time (default: 100).
:iscman:`named` could crash with an assertion failure when an RRSIG
query was received and :any:`stale-answer-client-timeout` was set to a
non-zero value. This has been fixed.
:iscman:`named` running as a resolver with the
:any:`stale-answer-client-timeout` option set to any value greater
than ``0`` could crash with an assertion failure, when the
:any:`recursive-clients` soft quota was reached. This has been fixed.
For more information, see:
(* Security fix *)
