Introduction

   BIND 9.8.5-P1 is the latest production release of BIND 9.8.

Security Fixes

   Prevents exploitation of a runtime_check which can crash named
   when satisfying a recursive query for particular malformed zones.
   (CVE-2013-3919) [RT #33690]

   A deliberately constructed combination of records could cause
   named to hang while populating the additional section of a
   response. (CVE-2012-5166) [RT #31090]

   Now supports NAPTR regular expression validation on all platforms,
   and avoids memory exhaustion compiling pathological regular
   expressions. (CVE-2013-2266)  [RT #32688]

   Prevents named from aborting with a require assertion failure
   on servers with DNS64 enabled.  These crashes might occur as a
   result of specific queries that are received.  (CVE-2012-5688)
   [RT #30792 / #30996]

   Prevents an assertion failure in named when RPZ and DNS64 are
   used together. (CVE-2012-5689) [RT #32141]

New Features

   Adds a new configuration option, "check-spf"; valid values are
   "warn" (default) and "ignore".  When set to \ 
"warn", checks SPF
   and TXT records in spf format, warning if either resource record
   type occurs without a corresponding record of the other resource
   record type.  [RT #33355]

   Adds support for Uniform Resource Identifier (URI) resource
   records. [RT #23386]

   Adds support for the EUI48 and EUI64 RR types. [RT #33082]

   Adds support for the RFC 6742 ILNP record types (NID, LP, L32,
   and L64). [RT #31836]
