Topic

An update for bind is now available for Red Hat Enterprise Linux 6.2 Advanced
Update Support.

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.

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 parsed signature records

for DNAME records. By sending a specially crafted query, a remote attacker could
use this flaw to cause named to crash. (CVE-2016-1286)

  • A denial of service flaw was found in the way BIND processed certain control

channel input. A remote attacker able to send a malformed packet to the control
channel could use this flaw to cause named to crash. (CVE-2016-1285)

Red Hat would like to thank ISC for reporting these issues.

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.
