DESCRIPTION
 "bind" is a name server (DNS) developed by the ISC and used in many
 internet and intranet sites.
 
 ISC (Internet Software Consortium) reported a remote denial of
 service vulnerability[2] in the BIND[1] server. A remote attacker can
 exploit this problem and shut down the name server.
 
 This vulnerability only affects the 9.x versions of the server and
 has no other consequence besides shutting down the service.
 
 An indication that the service has been shut down due to this problem
 are the following messages in the system log (/var/log/messages):
 
 named: message.c:808: REQUIRE(*rdataset == ((void *)0)) failed 
 named: exiting (due to assertion failure) 
 
 Please note that regular DNS traffic could also accidentally trigger
 this problem.
 
 ISC has released BIND version 9.2.1 to address this vulnerability.


SOLUTION
 It is recommended that all bind users upgrade their packages. The
 "named" service will be automatically restarted if it was already
 running before the upgrade.
