The Berkeley Internet Name Domain is an implementation of the Domain Name System protocols. BIND includes a DNS server ; a resolver library ; and tools for verifying that the DNS server is operating correctly. An uninitialized data structure use flaw was found in BIND when DNSSEC validation was enabled. A remote attacker able to send a large number of queries to a DNSSEC validating BIND resolver could use this flaw to cause it to exit unexpectedly with an assertion failure. Users of bind97 are advised to upgrade to these updated packages, which correct this issue. After installing the update, the BIND daemon will be restarted automatically.
