VMware ESX 3.5 Update 2 without patch ESX350-200808413-SG
3. Problem Description
a. Updated Openwsman
Openwsman is a system management platform that implements the Web
Services Management protocol (WS-Management). It is installed and
running by default. It is used in the VMware Management Service
Console and in ESXi.
The openwsman 2.0.0 management service on ESX 3.5 and ESXi 3.5 is
vulnerable to the following issue found by the SuSE Security-Team:
- Two remote buffer overflows while decoding the HTTP basic
authentication header
This vulnerability could potentially be exploited by users without
valid login credentials.
Openwsman before 2.0.0 is not vulnerable to this issue. The ESXi
3.5 patch ESXe350-200808201-O-UG updated openwsman to version 2.0.0.
The ESX 3.5 patch ESX350-200808205-UG updated openwsman to version
2.0.0. These patches are installed as part of the ESX and ESXi
Upgrade 2 release. The ESX patch can be installed individually.

The following VMware KB articles provide information on how to
obtain the version of openwsman in your environment and what a
possible workaround for the issue might be.
