3. Problem Description
 
   a. VMware ROM Overwrite Privilege Escalation
 
      A flaw in the way port-based I/O is handled allows for modifying
      Read-Only Memory that belongs to the Virtual DOS Machine.
      Exploitation of this issue may lead to privilege escalation on
      Guest Operating Systems that run Windows 2000, Windows XP
      32-bit, Windows Server 2003 32-bit or Windows Server 2003 R2
      32-bit.
 
      VMware would like to thank Derek Soeder of Ridgeway Internet
      Security, L.L.C. for reporting this issue to us.

   b. ESX third party update for Service Console kernel
 
      The ESX Service Console Operating System (COS) kernel is updated
      to kernel-400.2.6.18-238.4.11.591731 to fix multiple security
      issues in the COS kernel.
 
      The Common Vulnerabilities and Exposures project (cve.mitre.org)
      has assigned the names CVE-2011-2482, CVE-2011-3191 and
      CVE-2011-4348 to these issues.
 
      Column 4 of the following table lists the action required to
      remediate the vulnerability in each release, if a solution is
      available.

      ** One of the three issues, CVE-2011-2482, has already been
         addressed on ESX 4.1 in an earlier kernel patch. See
         VMSA-2012-0001 for details.
   
   c. ESX third party update for Service Console krb5 RPM
 
      This patch updates the krb5-libs and krb5-workstation RPMs to
      version 1.6.1-63.el5_7 to resolve a security issue.
 
      By default, the affected krb5-telnet and ekrb5-telnet services
      do not run. The krb5 telnet daemon is an xinetd service.  You
      can run the following commands to check if krb5 telnetd is
      enabled:

        /sbin/chkconfig --list krb5-telnet
        /sbin/chkconfig --list ekrb5-telnet
     
      The output of these commands displays if krb5 telnet is enabled.
     
      You can run the following commands to disable krb5 telnet
      daemon:

        /sbin/chkconfig krb5-telnet off
        /sbin/chkconfig ekrb5-telnet off
 
      The Common Vulnerabilities and Exposures project (cve.mitre.org)
      has assigned the name CVE-2011-4862 to this issue.
 
      Column 4 of the following table lists the action required to
