1. Summary

   Updated ESXi and ESX 3.5 packages address critical security issue in
   openwsman

2. Relevant releases

   VMware ESXi 3.5 Update 2 without patch ESXe350-200808501-I-SG

   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.

   Version Information and Workaround
   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.
   ESXi 3.5
     Refer to the VMware KB article at http://kb.vmware.com/kb/1005818.
   ESX 3.5
     Refer to the VMware KB article at http://kb.vmware.com/kb/1006878.

   Note: This vulnerability can be exploited remotely only if the
         attacker has access to the service console network.
         Security best practices provided by VMware recommend that the
         service console be isolated from the VM network. Please see
         http://www.vmware.com/resources/techresources/726 for more
         information on VMware security best practices.
