Updated bind packages that fix one security issue are now available for Red
Hat Enterprise Linux 5, 6, and 7.
Red Hat Product Security has rated this update as having Important security
impact. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available from the CVE link in the
References section.
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.
A denial of service flaw was found in the way BIND followed DNS
delegations. A remote attacker could use a specially crafted zone
containing a large number of referrals which, when looked up and processed,
would cause named to use excessive amounts of memory or crash.
(CVE-2014-8500)
All bind users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. After installing the
update, the BIND daemon (named) will be restarted automatically.
