RedHat: RHSA-2015-2658:01 Important: 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
records with malformed class attributes. A remote attacker could use this
flaw to send a query to request a cached record with a malformed class
attribute that would cause named functioning as an authoritative or
recursive server to crash. (CVE-2015-8000)
Note: This issue affects authoritative servers as well as recursive
servers, however authoritative servers are at limited risk if they perform
authentication when making recursive queries to resolve addresses for
servers listed in NS RRSETs.
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.
