[slackware-security]  bind (SSA:2021-118-01)

New bind packages are available for Slackware 14.0, 14.1, 14.2, and -current
to fix security issues.


Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
patches/packages/bind-9.11.31-i586-1_slack14.2.txz:  Upgraded.
  This update fixes bugs and the following security issues:
  A specially crafted GSS-TSIG query could cause a buffer overflow in the
  ISC implementation of SPNEGO.
  named crashed when a DNAME record placed in the ANSWER section during DNAME
  chasing turned out to be the final answer to a client query.
  Insufficient IXFR checks could result in named serving a zone without an SOA
  record at the apex, leading to a RUNTIME_CHECK assertion failure when the
  zone was subsequently refreshed. This has been fixed by adding an owner name
  check for all SOA records which are included in a zone transfer.
  For more information, see:

  (* Security fix *)
