Synopsis

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

Description

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

 - The TLS protocol allows weaker than expected security caused by a collision attack when using the MD5 hash function for signing a ServerKeyExchange message during a TLS handshake. An attacker can exploit this vulnerability using man-in-the-middle techniques to impersonate a TLS server and obtain credentials. (CVE-2015-7575)

 - IBM AIX does not require the newest version of TLS by default which allows a remote attacker to obtain sensitive information using man in the middle techniques. (CVE-2016-0266)

Solution

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