Security Advisory

Original Publication Date: 23 Feb, 2017

Latest   Publication Date: 14 Apr, 2018

Security Advisory 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.

^1 The specified products contain the affected code. However, F5 identifies
the vulnerability status as Not vulnerable because the attacker cannot exploit
the code in default, standard, or recommended configurations.


Security Advisory 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.

 1. Log in to the Configuration utility.
 2. Navigate to DNS > Delivery > Profiles > DNS.
 3. Select the affected DNS profile.
 4. For the DNS IPv6 to IPv4 option, select Disabled.
 5. Click Update.

Alternatively, if you have manually enabled RPZ in the BIND configuration, you
can disable RPZ.


Supplemental Information
