RedHat: RHSA-2016-0074:01 Moderate: bind97 security update
Summary
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 processed certain
malformed Address Prefix List (APL) records. A remote, authenticated
attacker could use this flaw to cause named to crash. (CVE-2015-8704)
Red Hat would like to thank ISC for reporting this issue.
All bind97 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.
Summary
Solution
Before applying this update, make sure all previously released errata
