[slackware-security]  bind (SSA:2026-168-01)

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-9.18.50-i586-1_slack15.0.txz:  Upgraded.
  This update fixes a security issue:
  Fix DNS64 owner case after DNAME restart.
  When BIND 9 is configured to use DNS64 and encounters a DNAME
  redirect, it could end up using freed memory for the DNS response
  owner name. This caused the response to contain corrupted data. This
  fix ensures the correct owner name is used when constructing the
  synthesized response after a DNAME redirect.
  ISC thanks Qifan Zhang of Palo Alto Networks for reporting the issue.
  (* Security fix *)
