The Berkeley Internet Name Domain (BIND) is an implementation of the DomainName System (DNS) protocols. BIND includes a DNS server (named); a resolverlibrary (routines for applications to use when interfacing with DNS); andtools for verifying that the DNS server is operating correctly.An uninitialized data structure use flaw was found in BIND when DNSSECvalidation was enabled. A remote attacker able to send a large number ofqueries to a DNSSEC validating BIND resolver could use this flaw to causeit to exit unexpectedly with an assertion failure. (CVE-2012-3817)Users of bind are advised to upgrade to these updated packages, whichcorrect this issue. After installing the update, the BIND daemon (named)will be restarted automatically.
