Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/bind-9.16.48-i586-1_slack15.0.txz: Upgraded.
 This update fixes bugs and security issues:
 Specific DNS answers could cause a denial-of-service condition due to DNS
 validation taking a long time.
 Query patterns that continuously triggered cache database maintenance could
 exhaust all available memory on the host running named.
 Restore DNS64 state when handling a serve-stale timeout.
 Specific queries could trigger an assertion check with nxdomain-redirect
 enabled.
 Speed up parsing of DNS messages with many different names.
