BIND 9.9.1-P4 Release Notes

Security Fixes

*A deliberately constructed combination of records could cause named
 to hang while populating the additional section of a response.
 [RT #31090]

*Prevents a named assert (crash) when queried for a record whose
 RDATA exceeds 65535 bytes.  [RT #30416]

*Prevents a named assert (crash) when validating caused by using
 "Bad cache" data before it has been initialized.  [RT #30025] 

*ISC_QUEUE handling for recursive clients was updated to address a
 race condition that could cause a memory leak.  This rarely
 occurred with UDP clients, but could be a significant problem for a
 server handling a steady rate of TCP queries.  [RT #29539 & #30233]

*A condition has been corrected where improper handling of
 zero-length RDATA could cause undesirable behavior, including
 termination of the named process.  [RT #29644]

New Features

*None

Feature Changes

*BIND now recognizes the TLSA resource record type, created to
 support IETF DANE (DNS-based Authentication of Named Entities)
 [RT #28989]

*A note will be added to the README in future releases to explain
 that the improved scalability provided by using multiple threads to
 listen for and process queries (change 3137, RT #22992) does not
 provide any performance benefit when running BIND on versions of
 the linux kernel that do not include the 'lockless UDP transmit
 path' changes that were incorporated in 2.6.39.  (Some linux
 distributors may have provided this functionality under their own
 version numbering systems).
