F5 Networks BIG-IP : BIND vulnerability (K34250741)

Medium Nessus Plugin ID 88851


The remote device is missing a vendor-supplied security patch.


db.c in named in ISC BIND 9.x before 9.9.8-P2 and 9.10.x before 9.10.3-P2 allows remote attackers to cause a denial of service (REQUIRE assertion failure and daemon exit) via a malformed class attribute. (CVE-2015-8000)


An attack may cause a denial-of-service (DoS) on the vulnerable BIND system by requesting a record that contains a malformed class attribute.

Although the BIG-IP, BIG-IQ, and Enterprise Manager software contains the vulnerable code, the BIG-IP, BIG-IQ, and Enterprise Manager systems do not use the vulnerable code in a way that exposes the vulnerability in the default configuration.

The BIG-IP system must meet both of the following conditions to be considered vulnerable :

A listener object is configured to use the local BIND. For example :

A virtual server with a DNS profile is configured with the Use BIND Server on BIG-IP option (this option is enabled by default for the DNS profile)

A DNS/GTM pool uses the Return to DNS load balancing method or its Alternate and Fallback load balancing methods set to None and all pools associated with the wide IP are unavailable.

The local BIND configuration is enabled with the non-default recursion yes; option.


Upgrade to one of the non-vulnerable versions listed in the F5 Solution K34250741.
