This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

The remote VMware ESXi / ESX host is missing one or more
security-related patches.

Description :

a. VMware vSphere client-side authentication memory corruption
vulnerability

VMware vCenter Server, vSphere Client, and ESX contain a
vulnerability in the handling of the management authentication
protocol. To exploit this vulnerability, an attacker must
convince either vCenter Server, vSphere Client or ESX to
interact with a malicious server as a client. Exploitation of
the issue may lead to code execution on the client system.

To reduce the likelihood of exploitation, vSphere components
should be deployed on an isolated management network.

The Common Vulnerabilities and Exposures Project (cve.mitre.org)
has assigned the name CVE-2013-1405 to this issue.

b. Update to ESX/ESXi libxml2 userworld and service console

The ESX/ESXi userworld libxml2 library has been updated to
resolve multiple security issues. Also, the ESX service console

libxml2-2.6.26-2.1.15.el5_8.5
libxml2-python-2.6.26-2.1.15.el5_8.5

These updates fix multiple security issues. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has
