Summary: An update for bind97 is now available for Red Hat Enterprise Linux 5. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop Workstation (v. 5 client) - i386, x86_64 3. Description: The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly. Security Fix(es): * A denial of service flaw was found in the way BIND handled a query response containing inconsistent DNSSEC information. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS response. (CVE-2016-9147) Red Hat would like to thank ISC for reporting this issue. 4. Solution: For details on how to apply this update,which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 After installing the update, the BIND daemon (named) will be restarted automatically. 5. Bugs fixed (https://bugzilla.redhat.com/): 1411367 - CVE-2016-9147 bind: assertion failure while handling a query response containing inconsistent DNSSEC information 6.
