RHEL 6 : bind (RHSA-2017:1582)
high Nessus Plugin ID 101099

Synopsis
The remote Red Hat host is missing one or more security updates for bind.Description
The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:1582 advisory.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 a query response containing CNAME or DNAME resource records in an unusual order. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS response. (CVE-2017-3137)
* 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)
Red Hat would like to thank ISC for reporting CVE-2017-3137.
Bug Fix(es):
* ICANN is planning to perform a Root Zone DNSSEC Key Signing Key (KSK) rollover during October 2017.
Maintaining an up-to-date KSK, by adding the new root zone KSK, is essential for ensuring that validating DNS resolvers continue to function following the rollover. (BZ#1458229, BZ#1458230, BZ#1458231, BZ#1458232, BZ#1458233)
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Update the RHEL bind package based on the guidance in RHSA-2017:1582.See Also
