The Berkeley Internet Name Domain (BIND) is an implementation of theDomain Name System (DNS) protocols. BIND includes a DNS server (named); aresolver library (routines for applications to use when interfacing withDNS); and tools for verifying that the DNS server is operating correctly.A denial of service flaw was found in BIND. A remote attacker could usethis flaw to send a specially-crafted DNS query to named that, whenprocessed, would cause named to crash when rejecting the malformed query.(CVE-2013-4854)All bind users are advised to upgrade to these updated packages, whichcontain a backported patch to correct this issue. After installing theupdate, the BIND daemon (named) will be restarted automatically.
