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.

Column 4 of the following table lists the action required to remediate the vulnerability in each release, if a solution is available.

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.

** 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

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 remediate the vulnerability in each release, if a solution is available.
