K08613310 : BIND vulnerability CVE-2017-3145

Security Advisory Description

BIND was improperly sequencing cleanup operations on upstream recursion fetch contexts, leading in some cases to a use-after-free error that can trigger an assertion failure and crash in named. (CVE-2017-3145)

Impact

BIG-IP

A remote attacker can use this flaw to make named, acting as a Domain Name System Security Extensions (DNSSEC) validating resolver, exit unexpectedly with an assertion failure by way of a specially crafted DNS request.

This vulnerability affects BIND only when configured as a recursive resolver with DNSSEC validation enabled. That mode of operation is not present in any default configuration but can be enabled.

ARX, Enterprise Manager, BIG-IQ, F5 iWorkflow, LineRate, and Traffix

There is no impact; these F5 products are not affected by this vulnerability.
