Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/bind-9.18.1-i586-1_slack15.0.txz: Upgraded.
 This update fixes bugs and the following security issues:
 An assertion could occur in resume_dslookup() if the fetch had been shut
 down earlier.
 Lookups involving a DNAME could trigger an INSIST when 'synth-from-dnssec'
 was enabled.
 A synchronous call to closehandle_cb() caused isc__nm_process_sock_buffer()
 to be called recursively, which in turn left TCP connections hanging in the
 CLOSE_WAIT state blocking indefinitely when out-of-order processing was
 disabled.
 The rules for acceptance of records into the cache have been tightened to
 prevent the possibility of poisoning if forwarders send records outside
 the configured bailiwick.
