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.A denial of service flaw was found in the way BIND handled queries forNSEC3-signed zones. A remote attacker could use this flaw against anauthoritative name server that served NCES3-signed zones by sending aspecially crafted query, which, when processed, would cause named to crash.(CVE-2014-0591)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.
