K80533167: BIND vulnerability CVE-2017-3135
Security Advisory
Original Publication Date: Feb 23, 2017
Updated Date: Feb 23, 2017
Vulnerability Description
** RESERVED ** This candidate has been reserved by an organization or
individual that will use it when announcing a new security problem. When
the candidate has been publicized, the details for this candidate will be
provided. (CVE-2015-3135)
BIG-IP configurations using DNS64 (the DNS IPv6 to IPv4 option configured
in the DNS profile) and Response Policy Zone (RPZ) rewriting (in the BIND
configuration) together are affected by this CVE.
Note: The DNS IPv6 to IPv4 option is disabled, by default, in the DNS
profile.
Note: RPZ Rewriting is an optional BIND 9.x configuration that allows
administrators to create DNS blacklists.
Impact
Remote attackers may be able to cause a BIND denial-of-service (DoS)
attack by making a query for an AAAA record.

exploit the code in default, standard, or recommended configurations.
Vulnerability Recommended Actions
If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. If the table lists only
an older version than what you are currently running, or does not list a
non-vulnerable version, then no upgrade candidate currently exists.
Mitigation
To mitigate this vulnerability, you can disable the DNS Ipv6 to IPv4 option
in the DNS profile, or disable RPZ in the BIND configuration. To disable the
DNS IPv6 to IPv4 option in the DNS profile, perform the following procedure:
Impact of action: The BIG-IP system does not map IPv4 addresses to IPv6
addresses for DNS resolutions.
Log in to the BIG-IP Configuration utility.
Navigate to DNS > Delivery > Profiles > DNS.
Click the name of the affected DNS profile.
For the DNS IPv6 to IPv4 option, select Disabled.
Click Update.
Alternatively, if you have manually enabled RPZ in the BIND configuration,
you can disable RPZ.
