Synopsis

The remote AIX host has a version of bind installed that is affected by multiple denial of service vulnerabilities.

Description

The version of bind installed on the remote AIX host is affected by the following vulnerabilities :

- A denial of service vulnerability exists in files sexpr.c and alist.c when handling control channel packets. An unauthenticated, remote attacker can exploit this, via crafted packets sent to the control channel (rndc) interface, to cause an assertion failure and daemon exit. (CVE-2016-1285)

- A denial of service vulnerability exists in files resolver.c and db.c when handling DNAME resource signatures. An unauthenticated, remote attacker can exploit this, via a crafted query that generates a response containing a signature record, to cause an assertion failure and daemon exit. (CVE-2016-1286)

Solution

A fix is available and can be downloaded from the IBM AIX website.
