"Updated bind packages that fix one security issue are now available
for Red Hat Enterprise Linux 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 flaw was found in the way BIND performed DNSSEC validation. An
attacker able to make BIND (functioning as a DNS resolver with DNSSEC
validation enabled) resolve a name in an attacker-controlled domain
could cause named to 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, which
contain a backported patch to correct this issue. After installing the
update, the BIND daemon (named) will be restarted automatically."
