RHSA-2017:1202 - Important: bind security update

Synopsis

Important: bind security update

Type/Severity

Security Advisory Important

Topic

An update for bind is now available for Red Hat Enterprise Linux 6.

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 handled DNSSEC validation. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS response. (CVE-2017-3139)

Note: This issue affected only the BIND versions as shipped with Red Hat Enterprise Linux 6. This issue did not affect any upstream versions of BIND.

Solution
