New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 3.6

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.
