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. A denial of service flaw was found in BIND. A remote attacker could use this flaw to send a specially-crafted DNS query to named that, when processed, would cause named to crash when rejecting the malformed query. All bind97 users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the update, the BIND daemon will be restarted automatically.
