SOL16356: BIND vulnerability CVE-2015-1349
Security Advisory
Original Publication Date: 04/02/2015
Description
named in ISC BIND 9.7.0 through 9.9.6 before 9.9.6-P2 and 9.10.x before
9.10.1-P2, when DNSSEC validation and the managed-keys feature are enabled,
allows remote attackers to cause a denial of service (assertion failure and
daemon exit, or daemon crash) by triggering an incorrect trust-anchor
management scenario in which no key is ready for use. (CVE-2015-1349)
Impact
This vulnerability can only be exploited if you explicitly enable DNSSEC
validation and managed-keys features in the BIND configuration. The default
BIND configuration on a BIG-IP system does not have these features enabled and
is not vulnerable. When exploited, the remote attacker may be able to cause
the named process to exit or crash, resulting in a denial-of-service (DoS).
Note: The BIG-IP DNSSEC feature does not use BIND code and is not vulnerable.
Status
F5 Product Development has assigned ID 507842 (BIG-IP), ID 511758 (Enterprise
Manager) and ID 511757 (BIG-IQ) to this vulnerability, and has evaluated the
currently supported releases for potential vulnerability.

features that are affected by the vulnerability, and for information about
releases or hotfixes that address the vulnerability, refer to the following

Note: As of February 17, 2015, AskF5 Security Advisory articles include the
Severity value. Security Advisory articles published before this date do not
list a Severity value.
Recommended Action
If the previous table lists a version in the Versions known to be not
vulnerable column, you can eliminate this vulnerability by upgrading to the
listed version. If the listed version is older than the version you are
currently running, or if the table does not list any version in the column,
then no upgrade candidate currently exists.
F5 responds to vulnerabilities in accordance with the Severity values
published in the previous table. The Severity values and other security
vulnerability parameters are defined in SOL4602: Overview of the F5 security
vulnerability response policy.
If you have manually enabled the DNSSEC validation and the managed-keys
features in the BIND configuration, you can mitigate this vulnerability by
disabling/removing these features in/from the BIND configuration. For more
information about BIND's DNSSEC validation and managed-keys features, refer to
the official documentation BIND DNSSEC Guide from Internet Systems Consortium
(ISC).
