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 flaw was found in the way BIND performed DNSSEC validation. An attackerable to make BIND (functioning as a DNS resolver with DNSSEC validationenabled) resolve a name in an attacker-controlled domain could cause namedto exit unexpectedly with an assertion failure. (CVE-2015-4620)Red Hat would like to thank ISC for reporting this issue.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.
