VMSA-2008-0016 : VMware Hosted products, VirtualCenter Update 3 and patches for ESX and ESXi resolve multiple security issues

This script is Copyright (C) 2009-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

a. Privilege escalation on 64-bit guest operating systems

VMware products emulate hardware functions, like CPU, Memory, and
IO.

A flaw in VMware's CPU hardware emulation could allow the
virtual CPU to jump to an incorrect memory address. Exploitation of
this issue on the guest operating system does not lead to a
compromise of the host system but could lead to a privilege
escalation on guest operating system. An attacker would need to
have a user account on the guest operating system.

Affected
64-bit Windows and 64-bit FreeBSD guest operating systems and
possibly other 64-bit operating systems. The issue does not
affect the 64-bit versions of Linux guest operating systems.

VMware would like to thank Derek Soeder for discovering
this issue and working with us on its remediation.

The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2008-4279 this issue.

b. Update for VirtualCenter fixes a potential information disclosure

This release resolves an issue where a user's password could be
displayed in cleartext. When logging into VirtualCenter Server 2.0
with Virtual Infrastructure Client 2.5, the user password might be
displayed if it contains certain special characters. The dialog
box displaying the password can appear in front or hidden behind
other windows.

To remediate this issue the VirtualCenter client installations must
be updated after updating to VirtualCenter Update 3

VMware would like to thank Mark Woollatt for reporting this issue
to VMware.

The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2008-4278 to this issue.

c. Update for VirtualCenter updates JRE to version 1.5.0_16

Update for VirtualCenter updates the JRE package to version 1.5.0_16,
which addresses multiple security issues that existed in the previous
version of JRE.

The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the names CVE-2008-3103, CVE-2008-3104, CVE-2008-3105,
CVE-2008-3106, CVE-2008-3107, CVE-2008-3108, CVE-2008-3109,
CVE-2008-3110, CVE-2008-3111, CVE-2008-3112, CVE-2008-3113,
CVE-2008-3114, CVE-2008-3115 to the security issues fixed in
JRE 1.5.0_16.
