Here are the details from the Slackware 13.37 ChangeLog:
+--------------------------+
patches/packages/bind-9.7.6_P2-i486-1_slack13.37.txz: Upgraded.
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]
Under heavy incoming TCP query loads named could experience a
memory leak which could lead to significant reductions in query
response or cause the server to be terminated on systems with
"out of memory" killers. [RT #29539]
A condition has been corrected where improper handling of zero-length
RDATA could cause undesirable behavior, including termination of
the named process. [RT #29644]
(* Security fix *)
